16. The intercept form of the parabola is
[tex]y=a(x-x_1)(x-x_2),[/tex]
where [tex]x_1, x_2[/tex] are two x-intercepts.
In your case,
[tex]x_1=2\\ \\x_2=-8[/tex]
so
[tex]y=a(x-2)(x-(-8))\\ \\y=a(x-2)(x+8)[/tex]
To find a, substitute coordinates of the point (-6,-4) parabola is passing through
[tex]-4=a(-6-2)(-6+8)\\ \\-4=-16a\\ \\a=\dfrac{1}{4}[/tex]
and
[tex]y=\dfrac{1}{4}(x-2)(x+8)[/tex]
17. The vertex form of the parabola equation is
[tex]-2p(y-k)=(x-h)^2,[/tex]
where (h,k) are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so
[tex]-2p(y-3)=(x-2)^2[/tex]
The vertex is 3 units from the focus, then
[tex]\dfrac{p}{2}=3\\ \\p=6[/tex]
The equation of the parabola is
[tex]-2\cdot 6(y-3)=(x-2)^2\\ \\y=-\dfrac{1}{12}(x-3)^2+3[/tex]

A room has dimensions 6.8m x 9.2m. Steven wants to paint the walls of the room. A large tin of paint covers 20m^2 and cost £11.75. Ignoring windows and doors, and allowing for 2 coats of paint, how much will it cost Steven to paint the room.
Answers
Answer:
Total cost to paint the room = £73.51
Step-by-step explanation:
Given:
Dimensions of the room = 6.8 m [tex]\times[/tex] 9.2 m
Cost of tin of paint = £11.75
A tin of paint covers an area = 20 [tex]m^2[/tex]
To find the cost of painting the room with two coats of paint.
Solution:
Area of the room = [tex]length\times width=6.8\ m\times 9.2\ m= 62.56\ m^2[/tex]
We will use unitary method to find the amount of paint required for the room.
If [tex]20\ m^2[/tex] of area is covered by 1 tin of paint.
For [tex]1\ m^2[/tex] of area, amount of paint required = [tex]\frac{1}{20}[/tex] of a tin
Then, for [tex]62.56\ m^2[/tex] amount of paint required = [tex]\frac{62.56}{20}=3.128[/tex] tins of paint.
For double coats twice paint must be required.
So, total amount of paint required for painting the room with two coats of paint = [tex]3.128\times 2=6.256[/tex] tins of paints.
Using unitary method to find total cost.
If 1 tin of paint costs = £11.75
6.256 tins of paint will cost = [tex]6.256\times \£11.75=\£73.508\approx\£73.51[/tex]
Total cost to paint the room = £73.51

Sunil takes 5 more days than Anil to a certain work . Anil left the work after 4days,Sunil takes 5days to complete the rest work . How many days they took to complete the work
Answers
Answer:
Anil would take 10 days and Sunil would take 15 days to complete the work.
Step-by-step Explanation:
To Determine:
How many days they took to complete the work?
Information Fetching and Solution steps:
Sunil takes 5 more days than Anil to a certain workAnil left the work after 4 daysSunil takes 5 days to complete the rest workLet is consider,
The number of days taken by Anil to complete the required work = d.
The number of days taken by Sunil to complete the required work = d + 5
Work done by Anil in one day = 1÷d
Work done by Sunil in one day = 1÷ (d+5)
Work done together by Anil and Sunil for one day = 1/d + 1/(d+5)
= (d+5+d)/d(d+5)
= (2d+5)/d(d+5)
Work done together by Anil and Sunil for 4 days = 4×(2d+5)/d(d+5) ....[A]
Work done by Sunil in 5 days = 5÷ (d+5) ....[B]
By adding equation [A] and [B], we can determine the complete work
[A] + [B] = 1
((4×(2d+5)/d(d+5))) + (5÷ (d+5)) = 1
8d+20+5d=1d(d+5)
13d+20=d²+5d
−d²+8x+20=0
(−d−2)(d−10)=0
d=−2 or d=10
As number of days can not be negative. So, d = 10. Therefore,
The number of days taken by Anil to complete
the required work = 10 days
The number of days taken by Sunil to complete
the required work = d+5 = 15 days
Hence, Anil would take 10 days and Sunil would take 15 days to complete the work.

janet is going to hire a makeup artist for a fashion show and is comparing prices. Austin charges $54 as a booking fee and an additional $80 per hour. Brad charges $69 per hour, plus a booking fee of $65. Depending on the length of the show, the cost could end up being the same for either artist. How long would the show be? What would the cost be?
Answers
Step-by-step explanationF(t)= 24 + 36*t
G(t) = 22 + 38*t
They are the same when 24 + 36t = 22 + 38t
Everything to right side: 0 = 22 + 38t - 24 - 36t
0 = 2t - 2
2 = 2t
t=1
THey are the same at one hour.
Longer than 1 hour, the first one is cheaper.
Here's the table to compare them side by side
t 24 + 36 t 22 + 38t
1/2 42 41
1 60 60
2 96 98
3 132 136
The fashion show needs to be 1 hour long for the cost of hiring either makeup artist Austin or Brad to be the same.
To determine how long the fashion show would need to be for the costs of hiring makeup artists Austin and Brad to be the same, we can set up an equation based on their respective fees. Austin charges a booking fee of $54 plus $80 per hour, while Brad charges a $65 booking fee plus $69 per hour.
Let's let 'h' be the number of hours for which the fashion show will run. For Austin, the total cost will be $54 + $80h. For Brad, the cost will be $65 + $69h. To find the number of hours where the costs are equal, we set the two expressions equal to each other:
54 + 80h = 65 + 69h
Now we solve for 'h':
Subtract 69h from both sides: 54 + 11h = 65
Subtract 54 from both sides: 11h = 11
Divide both sides by 11: h = 1
So, the fashion show needs to be 1 hour long for the cost of hiring either makeup artist to be the same, which would be $134.

Answer:
Part(B) is the correct answer
Step-by-step explanation:
Given functions are
f(x) = [tex]4x^3+5[/tex] and g(x) = [tex]\sqrt[3]{x-5/4}[/tex]
So both are inverse of each other
Since Definition of inverse function is
If a function f(x) is mapping from x to y , then the inverse function of f(x) maps
y back to x.
Solution
suppose
y = f(x)
y = [tex]4x^3+5[/tex]
in order to find inverse of f(x)
interchange the variables x and y
x = [tex]4y^3+5[/tex]
Now solve for y
Subtract 5 from both sides we get
[tex]4y^3[/tex] = x-5
Divide both sides by 4 we get
[tex]y^3[/tex] = (x-5)/4
[tex]y = \sqrt[3]{x-5/4}[/tex]
so this is the inverse of the f(x) and also from this we see that is [tex]g(x) = \sqrt[3]{x-5/4}[/tex]

An electronics store makes a profit of $72.00 for every television sold and $90.00 for every computer sold. The manager’s target is to make at least $360.00 a day on sales from televisions and computers. Let x = the number of televisions sold. Let y = the number of computers sold. Which of the following represents three possible solutions to the problem?
A. 72x+90y>360 (5,2),(3,3) and (1,4)
B. 72x+90y<360 (4,0),(2,2) and (1,1)
C. 72x+90y>360 (3,1),(2,2) and (1,0)
D 72x+90y>360 (4,0),(3,3) and (1,4)
Answers
Answer:
Option A, C and D is the three possible solution.Step-by-step explanation:
Each Television earns $72 and each Computer earns $90.
The manager’s target is to make at least $360.00 a day.
It is not clarified the exact number of Televisions and Computers.
Hence, as per the given condition, [tex]72x + 90y \geq 360\\8x + 10y \geq 40\\4x + 5y \geq 20[/tex].
Now we just need to check the given options, whether they satisfy the above equation, or not.
Except the option B, each inequality indicates a value greater than 360.
Hence, option B can not be the possible solution.
To meet the profit target of 72x + 90y ≥ 360, the correct points are listed in Option A: (5, 2), (3, 3), and (1, 4). These points meet the required profit condition.
To solve this problem, we need to find the inequality that represents the manager's profit target and identify the solutions that meet this condition. Given:
The profit per television is $72 (x represents the number of televisions sold).The profit per computer is $90 (y represents the number of computers sold).The manager’s goal is to make at least $360. This can be represented by the equation: 72x + 90y ≥ 360.
We need to check which option lists points that satisfy this inequality. Let's test the points:
Option A: 72x + 90y > 360 (5, 2), (3, 3), and (1, 4)
(5, 2): 72(5) + 90(2) = 360 + 180 = 540 (satisfies ≥ 360)(3, 3): 72(3) + 90(3) = 216 + 270 = 486 (satisfies ≥ 360)(1, 4): 72(1) + 90(4) = 72 + 360 = 432 (satisfies ≥ 360)Option B: 72x + 90y < 360 (4, 0), (2, 2), and (1, 1)
(4, 0): 72(4) + 90(0) = 288 (does not satisfy ≥ 360)(2, 2): 72(2) + 90(2) = 144 + 180 = 324 (does not satisfy ≥ 360)(1, 1): 72(1) + 90(1) = 72 + 90 = 162 (does not satisfy ≥ 360)Option C: 72x + 90y > 360 (3, 1), (2, 2), and (1, 0)
(3, 1): 72(3) + 90(1) = 216 + 90 = 306 (does not satisfy ≥ 360)(2, 2): 72(2) + 90(2) = 144 + 180 = 324 (does not satisfy ≥ 360)(1, 0): 72(1) + 90(0) = 72 (does not satisfy ≥ 360)Option D: 72x + 90y > 360 (4, 0), (3, 3), and (1, 4)
(4, 0): 72(4) + 90(0) = 288 (does not satisfy ≥ 360)(3, 3): 72(3) + 90(3) = 216 + 270 = 486 (satisfies ≥ 360)(1, 4): 72(1) + 90(4) = 72 + 360 = 432 (satisfies ≥ 360)Only Option A lists points that all satisfy the inequality 72x + 90y ≥ 360. Therefore, Option A is the correct answer.

Step-by-step explanation:
School spirit club wants to raise money by selling t-shirts. one local company charges a fixed fee of $75 for creating the design and $5 for each shirt that they print.
We have to find the club's income if they sell each t-shirt for $8.
Let the number of t-shirts that the club sell be equal to x.
So the cost of making x t-shirts = 75 + 5x
If the club sells x t-shirts , then the money they earn = 8x
Profit = selling price - cost price
= 8x - (75 + 5x)
= $(3x - 75)
The club also needs to sell at least 25 t-shirts to make a profit and from then on makes a profit of $3 on each t-shirt they sell.

How does the value of an expression change when it is expanded
Answers
Answer:
The value remains the same.
Step-by-step explanation:
using the expression: [tex](x + 1)^{2}[/tex],
where x = 2
substitute for x in the expression;
[tex](2 + 1)^{2}[/tex]
= [tex](3)^{2}[/tex]
=9
The value of the expression before expansion = 9
Lets expand the expression: [tex](x + 1)^{2}[/tex]
= (x + 1) (x + 1)
= [tex]x^{2}[/tex] + 2x + 1
substitute for x in the expression
= [tex]2^{2}[/tex] + 2(2) + 1
= 4 + 4 + 1 = 9
The value of the expansion after expansion = 9
The value remains the same before and after expansion.
The value of an expression, before and when it is expanded will be always same.
Let us consider that an expression,
[tex]f(x)=(x-1)^{2}[/tex]
Substitute x = 2 in above relation.
[tex]f(2)=(2-1)^{2}=1[/tex]
Now expand,
[tex]f(x)=(x-1)^{2}=x^{2} -2x+1\\\\f(2)=2^{2}-2*2+1\\\\f(2)=4-4+1\\\\f(2)=1[/tex]
Hence, the value of an expression, before and when it is expanded will be always same.

quart of red paint to make 2 1/2
quarts of purple paint. How much blue paint and how much red paint do you use?
Answers
Answer:
1 quart blue + 1 1/2 quart red
Step-by-step explanation:
Given:
Ratio of blue paint : red paint = 1/3 : 1/2
simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:
(1/3) x (3x2) : (1/2) x (3x2)
2 : 3
From this we can determine the fractions of red and blue paint used in any total purple mix
fraction of blue paint = 2/(2+3) = 2/5 of purple mix
fraction of red paint = 3/(2+3) = 3/5 of purple mix
we are given that we want to make 2 1/2 (= 5/2) quarts of purple paint
hence
amount of blue paint
= fraction of blue paint in purple mix x total amount of purple paint
= (2/5) x (5/2) = 1 quart
amount of red paint
= fraction of redpaint in purple mix x total amount of purple paint
= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart

An airplane has 29 seats. The price for a coach seat is $600 in the price for a first class seat is $1050. The airline collected a total of $21,900 for the flight. How many coach seats were sold
Answers
Answer:
19 coach seats
Step-by-step explanation:
let the number of coach seats be C and number of first class seats be F
given that the total number of seats is 29,
C + F = 29 ---------(eq 1)
also given that each coach seat = $600, each 1st class seat is $1050 and a total of $21900 was collected,
600C + 1,050F = 21,900 -------(eq 2)
we have 2 equations and 2 unknowns, we can solve the system of equations by elimination
(eq 1) x 1,050 gives us:
1,050 (C + F) = 1,050(29)
1,050C + 1,050F = 30,450 ----- (eq 3)
by elimination, subtract eq 2 from eq 3
(1,050C + 1,050F) - (600C + 1,050F) = 30,450 - 21,900
1,050C - 600C = 8,550
450C = 8550
C = 855 /450
C = 19
what is the sum of 7.09 + 13.95
Answers
Answer:
21.04
Step-by-step explanation:
Start by adding the hundredths category. 0.09 + 0.05 = 0.14, this means that your hundredths column will be a 4, and you will carry the 1 over to the tenths.
Now add your tenths. 0.0 + 0.9 + 0.1 = 1.0, which means that your tenths column is a 0. Carry the 1 over to the whole numbers.
Now add your whole numbers. 7 + 13 + 1 = 21. Combine your terms and you get 21.04
Final answer:
21.04
Explanation:
To find the sum of 7.09 and 13.95, we simply add the two numbers together, aligning the decimal points vertically.
Add the hundredths place: 9 (from 7.09) + 5 (from 13.95) = 14. Write down 4 and carry over 1 to the tenths place.Add the tenths place: 0 (from 7.09) + 9 (from 13.95) + 1 (the carryover) = 10. Write down 0 and carry over 1 to the ones place.Add the ones place: 7 (from 7.09) + 3 (from 13.95) + 1 (the carryover) = 11. Hence, write down 1 and carry over another 1 to the tens place.Add the tens place, which is just the carryover: 1 (from the carryover) + 1 (from 13.95) = 2. So, write down 2.Putting it all together, we get 21.04 as the final sum.

Suppose you have $30 to spend on a bag is tootsie rolls that are worth $3 and bags of lolli-pops worth $5.If you have to use all of their money , What combinations of candy bags can they buy ? Construct a liner equation and find /explain the y -intercept,x-intercept ,and slope
Answers
Answer:
Part a) [tex]3x+5y=30[/tex]
Part b) see the explanation
Part c) see the explanation
Step-by-step explanation:
Part a) Construct a liner equation
Let
x ----> the number of bags of tootsie rolls
y ----> the number of bags of lolly-pops
we know that
The number of bags of tootsie rolls bought multiplied by their price ($3) plus the number of bags of lolly-pops bought multiplied by their price ($5) must equal $30
so
The linear equation that represent this problem is
[tex]3x+5y=30[/tex]
Part b) Find the intercepts
Find the y-intercept
The y-intercept is the value of y when the value of x s equal to zero
In this context, the y-intercept is the number of bags of lolly-pops that i can buy when the number of bags of tootsie rolls is equal to zero
For x=0
[tex]3(0)+5y=30[/tex]
[tex]y=6[/tex]
The y-intercept is the point (0,6)
so
I can buy 6 bags of lolly-pops and 0 bags of tootsie rolls
Find the x-intercept
The x-intercept is the value of x when the value of y s equal to zero
In this context, the x-intercept is the number of bags of tootsie rolls that i can buy when the number of bags of lolly-pops is equal to zero
For y=0
[tex]3x+5(0)=30[/tex]
[tex]x=10[/tex]
The x-intercept is the point (10,0)
so
I can buy 10 bags of tootsie rolls and 0 bags of lolly-pops
Part c) Find the slope
we have
[tex]3x+5y=30[/tex]
isolate the variable y
[tex]5y=-3x+30[/tex]
[tex]y=-\frac{3}{5}x+6[/tex]
The slope is m=-3/5 ---> is negative because is a decreasing function
That means ---> For every three less lollipops you get, you can have 5 more tootsie rolls

Simplify the expression 8(5x- 3y)
Answers
Answer:
40x-24y
Step-by-step explanation:
Step 1: Rewrite equation
8(5x-3y)
Step 2: Distribute
Distribution in math is when you multiply the number on the outside (8) with both numbers in the inside (5x;-3y). Let’s do this now.
8(5x-3y)
40x-24y
This is your final answer! It can no longer be simplified, as y and x are different variables.

$11.62
Answers
Answer:8-oz jar
First, we have to find out what is the unit rate of the 2-oz jar. $1.50÷2 is $.75.
Second, we have to find the unit rate of the 4-oz jar. $2.92÷4=$73.
Third, we have to find the unit rate of the 8-oz jar. $5.68=$.71.
Fourth, we have to find the unit rate of the 16-oz jar. The division for this one may be tricky. From dividing $11.62 by 16, is stopped at the 3rd number I got from dividing. I got $.726. This is not a value of cents and the value can't go in the thousandths place. So, I rounded .726. I got $.73. So $11.62÷16=$.73.
Lastly, you have to compare the amounts.
The lowest amount or better buy, is $.71 or 8-oz jar.
