The height ,h, in feet of a baseball that is popped up into the air is a quadratic function of the time,t, in seconds, since it was hit. An equation that may model this situation is h(t)=4+60t-16t^2. Answers the following questions accurately, rounding to two decimals places when needed.
Answer: [tex]4\ feet[/tex]
Step-by-step explanation:
The missing question is: "How high is the ball when it strikes the bat?"The exercise provides you the following Quadratic function:
[tex]h(t)=4+60t-16t^2[/tex]
You know that it represents the height (in feet) of the ball as a function of the time (in seconds) since the ball hit the bat.
Based on this, you can conclude that when the ball strikes the bat the time in seconds is:
[tex]t=0[/tex]
Therefore, in order to calculate the height in feet of the ball when it strikes the bat, you need to subsititute [tex]t=0[/tex] into the function and then evaluate.
So, you get:
[tex]h(0)=4+60(0)-16(0)^2\\\\h(0)=4[/tex]

A potter works 4 days a week, makes 14 pots per day on average, and
charges $24 a pot. If she lowers her price to $16 a pot, by how many pots per
day on average must she increase her production to make the same amount
of money per 4-day workweek?
Final answer:
To maintain the same weekly revenue after reducing her pot price from $24 to $16, a potter working 4 days a week must increase her daily production from 14 pots to 21 pots, which is an increase of 7 pots per day.
Explanation:
The question involves a potter who initially makes 14 pots per day and works 4 days a week, charging $24 per pot. To find out by how many pots per day she must increase her production after lowering her price to $16 per pot, to make the same amount of money, we first calculate her current weekly revenue:
14 pots/day * $24/pot * 4 days = $1,344 per week.After reducing the price to $16 per pot, we need to determine how many pots per day she needs to sell to maintain the same weekly revenue of $1,344:
$1,344 / ($16/pot) / 4 days = 21 pots per day.Therefore, she needs to sell 7 more pots per day (21 pots - 14 pots) to maintain her weekly revenue.
a line intersects the points (3,-4) and (1,2) what is the slope intercept equation for this line
Answer:
y = - 3x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (3, - 4) and (x₂, y₂ ) = (1, 2)
m = [tex]\frac{2+4}{1-3}[/tex] = [tex]\frac{6}{-2}[/tex] = - 3, thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (1, 2), then
2 = - 3 + c ⇒ c = 2 + 3 = 5
y = - 3x + 5 ← equation of line
Answer:
y=-3x+5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-(-4))/(1-3)
m=(2+4)/-2
m=6/-2
m=-3
y-y1=m(x-x1)
y-(-4)=-3(x-3)
y+4=-3(x-3)
y=-3x+9-4
y=-3x+5

Expression 1:
[tex]m ^ 3 + m ^ 3 =[/tex]
They are similar terms so we can add.
[tex]2m ^ 3[/tex]
Expression 2:
[tex]10 + 3c + 5d-7c + d =[/tex]
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
[tex]10 + 3c-7c + 5d + d =\\10-4c + 6d[/tex]
Answer:
[tex]m ^ 3 + m ^ 3 = 2m ^ 3\\10 + 3c + 5d-7c + d = 10-4c + 6d[/tex]
What is the solution to 5x-8y=-45 9x-8y=49
To find the solution to the system of equations 5x - 8y = -45 and 9x - 8y = 49, you can solve by elimination. The solution is x = 23.5 and y = 20.3125.
Explanation:To find the solution to the system of equations:
5x - 8y = -45
9x - 8y = 49
Subtract the second equation from the first equation to eliminate y. This gives you 5x - 9x = -45 - 49, which simplifies to -4x = -94.Solve for x by dividing both sides of the equation by -4. This gives you x = -94/-4, or x = 23.5.Substitute the value of x into one of the original equations to solve for y. Using the first equation, we have 5(23.5) - 8y = -45. Simplifying this equation gives you 117.5 - 8y = -45.Subtract 117.5 from both sides of the equation to isolate -8y. This gives you -8y = -45 - 117.5, which simplifies to -8y = -162.5.Solve for y by dividing both sides of the equation by -8. This gives you y = -162.5/-8, or y = 20.3125.A doctor administers a drug to a 36-kg patient, using a dosage formula of 51 mg/kg/day.

What is the sum of the first 29 terms of the arithmetic sequence? −43,−35,−27,−19,... Enter your answer in the box. S29=
Answer: [tex]S_{29}[/tex] = 2001
Step-by-step explanation:
Since the sequence is an arithmetic sequence , it means that a common difference must exist.
Let the terms in the sequence be [tex]T_{1}[/tex] , [tex]T_{2}[/tex] , [tex]T_{3}[/tex] , [tex]T_{4}[/tex] , ...
Then common difference = [tex]T_{2}[/tex] - [tex]T_{1}[/tex] = [tex]T_{3}[/tex] - [tex]T_{2}[/tex] = 8
That is , the common difference (d) = 8
The formula for calculating sum of n terms is given by :
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a + (n-1)d ]
Where ;
n = number of terms
a = first term
d = common difference
From the question :
n = 29
a = -43
d = 8
Substituting into the formula , we have
[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] [ 2{-43} + (29-1)(8) ]
[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] (-86 +224)
[tex]S_{29}[/tex] = [tex]\frac{29}{2}[/tex] ( 138)
[tex]S_{29}[/tex] = [tex]\frac{4002}{2}[/tex]
[tex]S_{29}[/tex] = 2001

∠ APW and ∠ WPZ
∠ ZPW and ∠ ZPB
∠ BPZ and ∠ WPA
∠ ZPB and ∠ APZ
Answer:
∠ZPB and ∠APZ are two adjacent supplementary angles
Step-by-step explanation:
we know that
Two angles are Adjacent when they have a common side and a common vertex
Two angles are supplementary if their sum is equal to 180 degrees
In this problem we have that
[tex]m\angle ZPB=90^o[/tex] ----> given problem
[tex]m\angle APZ=90^o[/tex] ----> given problem
so
[tex]m\angle ZPB+m\angle APZ=180^o[/tex]
∠ZPB and ∠APZ are supplementary angles
and
∠ZPB and ∠APZ have a common side (ZP) and a common vertex (P)
therefore
∠ZPB and ∠APZ are two adjacent supplementary angles
Answer: ∠ZPB and ∠APZ are two adjacent supplementary angles

Given the rectangle below with length 8 and width 6
a) construct the midpoints of all four sides of the rectangle.
b) connect the midpoints to form another quadrilateral. What type of quadrilateral is formed? Justify your answer.
c) find the area of the quadrilateral you formed.
( There is a picture of a rectangle below. I'm willing to give all my points away.)
Answer:
a) Given in attachment.
b) Quadrilateral formed is a rhombus. Because length of all the sides are equal and angle between adjacent sides is not 90°.
c) 24 unit².
Step-by-step explanation:
Let rectangle be ABCD with length 8 and width 6
And mid-points be E,F,G,H
Now, join the mid-points .
we know that angle between adjacent sides in a rectangle is 90°.
⇒ ΔFAE forms a right angle triangle with 90° at A.
By, pythagoras theorem , EF² = AF² + AE²
⇒ EF² = 3² + 4² = 25
⇒ EF = 5;
In the same way, FG = GH = HE = 5
⇒ the quadrilateral is either square or rhombus.
Now, from ΔFAE, sin(∠AEF) = [tex]\frac{4}{5}[/tex]
(sinФ = opposite side / hypotenuse)
⇒ ∠AEF = 53°;
In similar manner;
∠DEH = 53° . Now ∠FEH = 180 - 53 - 53 = 74° (sum of angles on a straight line is 180°)
⇒ the quadrilateral is rhombus has angle between adjacent sides is 53° and not 90°.
Now, to find the area of rhombus, join EG and FH. And name the intersection point as J.
consider ΔEJF,
it is a right angled triangle at J, and also quadrilateral AFJE forms rectangle, as diagonals intersect perpendicular in a rhombus.
⇒ FJ = 3 and EJ = 4.
⇒ area of this triangle = 1/2 × base × height
= 1/2 × EJ × JF = 1/2 × 3 ×4 = 6
similarly triangles FJG, GJH, HJE.
⇒ area of rhombus = 6+6+6+6 = 24.

First, do distributive property:
2(5+3x)+(x+10) Distribute the 2 to the 5 and the 3x; multiply them
10+6x+x+10 Since (x+10) would be 1 times x and 10, it's just x+10
Then, do communitive property:
10+6x+x+10 What we found in the last step, now combine the like terms
20+7x This is what you get since 10+10=20 and 6x+x=7x
The answer:
20+7x or 7x+20

A sheriff patrols several neighborhoods in her patrol car it requires 4/15 of an hour to patrol an entire neighborhood.Can a sheriff patrol 2 3 4 or 6 neighborhoods in 8/9 an hour
Answer:
3
Step-by-step explanation:
For this question, you need to make change the denominators of the fractions to be equal, making them the same lowest common denominator.
8/9 -> 40/45
4/15 -> 12/45
Since 12 goes into 40 3 1/3 times, he can patrol that many neighborhoods in 8/9's of an hour, which is rounded to 3 because he doesn't have enough time for 4.
To determine if the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour, we need to calculate the time it takes to patrol a single neighborhood and then divide the given time by that value. The answer is 10/3, which means the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour.
Explanation:To determine if the sheriff can patrol 2, 3, 4, or 6 neighborhoods in 8/9 of an hour, we need to calculate the time it takes to patrol a single neighborhood and then divide the given time by that value.
Given that it takes 4/15 of an hour to patrol a single neighborhood, we can divide 8/9 by 4/15.
To divide fractions, we multiply by the reciprocal, so 8/9 ÷ 4/15 becomes 8/9 × 15/4. Multiplying across, we get (8 × 15) / (9 × 4) = 120 / 36 = 10 / 3.

The gardeners at Middleton Place Gardens want to plant a total of 45 white and pink hydrangeas in one flower bed. In another flower bed, they want to plant 119 hydrangeas. In this bed, they want 2 times the number of white hydrangeas and 3 times the number of pink hydrangeas as in the first bed. Use a system of equations to find how many white and how many pink hydrangeas the gardeners should buy altogether.
The gardeners should buy 48 white and 116 pink hydrangeas altogether
Step-by-step explanation:
The given is:
The gardeners at Middleton Place Gardens want to plant a total of 45 white and pink hydrangeas in one flower bedIn another flower bed, they want to plant 119 hydrangeas, in this bed, they want 2 times the number of white hydrangeas and 3 times the number of pink hydrangeas as in the first bedWe need to find how many white and how many pink hydrangeas the gardeners should buy altogether
Assume that the number of white hydrangeas is x and the number of pink hydrangeas in the first bed
∵ The first bed has x white hydrangeas
∵ The first bed has y pink hydrangeas
∵ The total of white and pink hydrangeas in 1st bed is 45
- Equate the sum of x and y by 45
∴ x + y = 45 ⇒ (1)
∵ In the 2nd bed the number of the white hydrangeas is 2 times
as in the 1st bed
∵ The number of the pink hydrangeas is 3 times as in the 1st bed
∵ The number of the hydrangeas in the 2nd bed is 119
- Multiply x by 2 and y by 3, then add the products and equate
the sum by 119
∴ 2x + 3y = 119 ⇒ (2)
Now let us solve the system of equations
Multiply equation (1) by -3 to eliminate y
∵ -3x - 3y = -135 ⇒ (3)
- Add equations (2) and (3)
∴ -x = -16
- Divide both sides by -1
∴ x = 16
- Substitute the value of x in equation (1) to find y
∵ 16 + y = 45
- Subtract 16 from both sides
∴ y = 29
∵ The number of the white hydrangeas in the 1st bed is x
∵ The number of the white hydrangeas in the 2nd bed is 2x
∴ The total number of the white hydrangeas = x + 2x = 3x
∵ x = 16
∴ The total number of the white hydrangeas = 3(16) = 48
∵ The number of the pink hydrangeas in the 1st bed is y
∵ The number of the pink hydrangeas in the 2nd bed is 3y
∴ The total number of the pink hydrangeas = y + 3y = 4y
∵ y = 29
∴ The total number of the pink hydrangeas = 4(29) = 116
The gardeners should buy 48 white and 116 pink hydrangeas altogether
