A) 60

B) 65

C) 70

D) 75

Answer:

298

Step-by-step explanation:

Given

(8 - (- 9))² + (-3 - (- 6))² ← evaluate the parenthesis before squaring

= (8 + 9)² + (- 3 + 6)²

= 17² + 3²

= 289 + 9

= 298

Answer: (8+9)^2 + (-3 + 6)^2

= 17^2 + 3^2

= 289 + 9

= 298. ANS.

If a local city collects 8% sales tax if the total purchase was $216 then $17.28 is collected for sales tax.

A relative value indicating hundredth parts of any quantity is known as Percentage.

Given that a  local city collects 8% sales tax

The total purchase was $216.

We need to find the amount collected for sales tax.

To find this we have to find 8% of 216.

Convert 8% to the decimal value.

8/100=0.08

Now multiply 0.08 with 216

0.08×216

$17.28

Hence, if a local city collects 8% sales tax if the total purchase was $216 then $17.28 is collected for sales tax.

The amount collected for sales tax is $16.

Step 1: Understand the Problem

The total purchase amount ($216) includes the sales tax. We need to find how much of this amount is the sales tax itself.

Step 2: Convert the Percentage to a Decimal

Convert the sales tax rate from a percentage to a decimal.

[tex]\[ \text{Sales Tax Rate} = \frac{8}{100} = 0.08 \][/tex]

Step 3: Set Up the Equation

Let ( P ) be the pre-tax purchase amount and ( T ) be the total amount including tax. The relationship can be written as:

[tex]\[ T = P + \text{Sales Tax} \][/tex]

Since the sales tax is 8% of the pre-tax amount,

[tex]\[ \text{Sales Tax} = 0.08 \times P \][/tex]

Thus, the total amount is:

[tex]\[ T = P + 0.08P = 1.08P \][/tex]

Step 4: Solve for the Pre-Tax Amount

We know the total amount ( T ) is $216.

[tex]\[ 216 = 1.08P \][/tex]

To find ( P ):

[tex]\[ P = \frac{216}{1.08} \][/tex]

[tex]\[ P \approx 200 \][/tex]

Step 5: Calculate the Sales Tax

Now, find the sales tax:

[tex]\[ \text{Sales Tax} = 0.08 \times P \][/tex]

[tex]\[ \text{Sales Tax} = 0.08 \times 200 \][/tex]

[tex]\[ \text{Sales Tax} = 16 \][/tex]

Therefore the amount collected for sales tax is $16.

Answer:

If x is greater than 1 it is growth, if it less than it is decay

Step-by-step explanation:

Answer: option c

Step-by-step explanation:

You can use these identities:

[tex]sin\alpha=\frac{opposite}{hypotenuse}\\\\tan\alpha=\frac{opposite}{adjacent}[/tex]

Then, using the angle that measures 30 degrees, you know that:

[tex]\alpha=30\°\\opposite=8\\adjacent=b[/tex]

Substituting:

[tex]tan(30\°)=\frac{8}{b}[/tex]

Now you must solve for b:

[tex]b=\frac{8}{tan(30\°)}\\\\b=8\sqrt{3}[/tex]

Using the angle that measures 30 degrees, you know that:

[tex]\alpha=30\°\\opposite=8\\hypotenuse=c[/tex]

Substituting:

[tex]sin(30\°)=\frac{8}{c}[/tex]

Now you must solve for c:

[tex]c=\frac{8}{sin(30\°)}\\\\c=16[/tex]

ANSWER

The correct answer is C

EXPLANATION

The side adjacent to the 60° angle is 8 units.

The hypotenuse is c.

Using the cosine ratio, we have

[tex] \cos(60 \degree) = \frac{adjacent}{hypotenuse} [/tex]

[tex]\cos(60 \degree) = \frac{8}{c} [/tex]

[tex] \frac{1}{2}= \frac{8}{c} [/tex]

Cross multiply

[tex]c = 8 \times 2 = 16[/tex]

Also

[tex]\cos(30 \degree) = \frac{b}{c} [/tex]

[tex]\cos(30 \degree) = \frac{b}{16} [/tex]

[tex] \frac{ \sqrt{3} }{2} = \frac{b}{16} [/tex]

Multiply both sides by 16

[tex]b = 16 \times \frac{ \sqrt{3} }{2} [/tex]

[tex]b = 8 \sqrt{3} [/tex]

The correct answer is C

For this case we must find the inverse of the following function:

[tex]f (x) = x ^ 2 + 7[/tex]

For this we follow the steps below:

Replace f(x) with y:

[tex]y = x ^ 2 + 7[/tex]

We exchange the variables:

[tex]x = y ^ 2 + 7[/tex]

We solve the equation for "y", that is, we clear "y":

[tex]y^ 2 + 7 = x[/tex]

We subtract 7 on both sides of the equation:

[tex]y ^ 2 = x-7[/tex]

We apply square root on both sides of the equation to eliminate the exponent:

[tex]y = \pm\sqrt {x-7}[/tex]

We change y by[tex]f ^ {- 1} (x):[/tex]

[tex]f ^ {- 1} (x) =\pm\sqrt {x-7}[/tex]

How many classes could Anna take so that the total cost for the month would be the same?

5 classes

What is the total monthly cost when it is the same for both gyms?

$37.50

Step-by-step explanation:

The number of classes Anna could take so the total cost for the month would be the same is 5.

The total monthly cost when it is the same for both gyms would be $37.50.

When the total cost is the same, both equations for the gym would be equal to each other.

7.5x = 5.5x + 10

In order to determine the value of x, take the following steps:

Combine similar terms

7.5x - 5.5x = 10

Add similar terms together

2x = 10

Divide both sides by 2

x = 5

Total cost = 7.5 x 5 = $37.50

6,18,8,4,18,20,10,10,21,6,17,18

Arrange the data in ascending order

4,6,6,8,10,10,17,18,18,18,20,21

Part A

Mean = 156/12 = 13 is correct

Median = 15 is incorrect because the data is not arranged. Median when there are even numbers will be: 10+17/2 = 13.5

Mode = 10 is incorrect, because mode is most repeating value and in the data set it is 18 so, Mode = 18

Part B

10,12 and 52 should be added in data set in ascending order

4,6,6,8,10,10,10,12,17,18,18,18,20,21,52

Mean = 230/15 = 15

Median = Middle term as odd numbers = 8th term = 12

Mode = 10 and 18

Part C

Both median and mean are used to measure central tendency.

The best measure of central tendency is considered median because the mean is affected by the presence of outliers while median is not affected by outliers.

Peter will be 75 years old in 47 years.

Answer:

In 47 years Peter will be 75 years old

Step-by-step explanation:

If Peter will be 54 years old in 26 years then subtract 26 from 54

54-26=28

This means that Peter is 28 right now, if you want to double check that work then add 26 to 28 implying that in 26 years Peter with be 54 years old

28+26=54

This shows that your calculations are correct! Now you have to figure out how many years from now will Peter be when he turns 75 years old, so you subtract his current age which is 28 from 75

75-28=47

Now to double check this add 47 to his current age which is 28

28+47= 75

This shows that your calculations are correct and it will take 47 years for Peter to be 75 years old!

Answer:

[tex]f * g = 21x ^ 2 + 32x +12[/tex]

Domain: all real numbers [tex](-\infty, \infty)[/tex]

Step-by-step explanation:

We have the functions [tex]f (x) = 3x + 2[/tex] and [tex]g (x) = 7x + 6[/tex]

We want to find f*g. Then we must multiply the function f by the function g.

Note that the function [tex]f (x) = 3x +2[/tex] is a linear function, therefore its domain is all real numbers. In the same way the function [tex]g (x) = 7x + 6[/tex] is also a linear function and its domain is all real numbers.

The multiplication of f * g will be

[tex]f * g = (3x + 2) (7x + 6)\\\\f * g = 21x ^ 2 + 18x + 14x +12\\\\f * g = 21x ^ 2 + 32x +12[/tex]

The function g(x) is a quadratic function and its domain is the intercept of the domain of f(x) with the domain of g(x), that is, all real numbers.

EXPLANATION

The center of the circle is (0,0).

The circle passes through (-1,-3).

The radius can be obtained using the distance formula:

[tex]r = \sqrt{(0 - 1)^{2} + {(0 - - 3)}^{2} } = \sqrt{10} [/tex]

The equation is given as:

[tex]( {x - h)}^{2} + ( {y - k)}^{2}= {r}^{2} [/tex]

Where (h,k) is the center and r is the radius.

This implies that;

[tex]( {x - 0)}^{2} + ( {y - 0)}^{2}= {( \sqrt{10)} }^{2} [/tex]

[tex] {x}^{2} + {y}^{2} = 10[/tex]

Step-by-step explanation:

We have the graph of a line that passes through the points (0,5) and (2, 1).

The equation of the line that passes through these points is found in the following way:

[tex]y = mx + b[/tex]

Where

m = slope

[tex]m = \frac {y_2-y_1}{x_2-x_1}\\\\m = \frac{1-5}{2-0}\\\\m = -2\\\\b = y_2-mx_2\\\\b = 1 -(-2)(2)\\\\b = 5[/tex]

So

[tex]y = -2x + 5[/tex]

We must apply to this function the transformation[tex]f (x-4)[/tex].

We know that a transformation of the form

[tex]y = f (x + h)[/tex] shifts the graph of the function f(x) h units to the right if [tex]h <0[/tex], or shifts the function f(x) h units towards the left if [tex]h> 0[/tex].

In this case [tex]h = -4 <0[/tex] then the transformation [tex]f(x-4)[/tex] displaces the graph 4 units to the right.

Therefore if f(x) passes through the points (0,5) and (2,1) then [tex]f (x-4)[/tex] passes through the points (4, 5) (6, 1)

And its equation is:

[tex]y = -2(x-4) +5\\\\y = -2x +13[/tex]

The sum of the integers -9, 4, 10, -4, 8, -4 is calculated by adding the numbers together, which totals 5.

To find the sum of the integers -9, 4, 10, -4, 8, -4, we add them together:

-9 + 4 + 10 + (-4) + 8 + (-4) = 5.

We can group the positive and negative numbers to make this simpler:

(4 + 10 + 8) = 22

(-9 - 4 - 4) = -17

Adding the results of the positive and negative groups gives us:

22 + (-17) = 5.

Therefore, the sum of the given integers is 5.

The relationship between Roberts age and Julia’s age is given by:

r = j+3            ....[1]

where,

r is the Robert's age and j represents the Julia's age in years

We have to find the table of values represents the relationship between Roberts age and Julia’s age

if r = 9 years

then;

[tex]9 = j+3[/tex]

Subtract 3 from both sides we have;

6 = j

or

j = 3 years

Similarly:

if r = 15 years

then;

[tex]15= j+3[/tex]

Subtract 3 from both sides we have;

12 = j

or

j = 12 years

If r = 21 years

then;

[tex]21= j+3[/tex]

Subtract 3 from both sides we have;

18 = j

or

j = 18 years

Therefore, the table of values represents the relationship between Roberts age and Julia’s age is, Table C

A) For all x > 0 the graph will be higher.

EXPLANATION

Jack's graph has equation

y=2x

This graph passes through the origin and has slope 2.

Nina's graph is y=5x.

This graph also passes through the origin and has slope 5.

Since 5 is greater than 2, for all x>0, Nina's graph will be higher.

Answer: A

Step-by-step explanation: Changing the 2 to a 5 makes an exponential growth function increase at a faster rate. Therefore, for all x > 0 the graph will be higher. At x = 0 the graphs will have the same value and for all x < 0, Nina's graph will be lower.
