Graph the image of the figure after a rotation of 90° counterclockwise.

Answers

Answer 1
I have no idea what figure you are talking about, but to make any figure rotate 90 counter - clockwise you would make the x value a negative like ( 1, 1) would become
( -1, 1)

Rewrite:                         y = 8x + 4Swap x and y:               x = 8y + 4

Step 3: Find Inverse (Solve for y)

Subtract 4 on both sides:                    x - 4 = 8yDivide both sides by 8:                       (x - 4)/8 = yRewrite:                                                 y = (x - 4)/8Rewrite:                                                f⁻¹(x) = (x - 4)/8

0.5x + 1.75 = 10 and last one is
0.75h + 3 = 12

Answers

Answer:

13, 16.5, 12

Step-by-step explanation:

-7x= -91 divide both sides by -7 to isolate x

[tex]\frac{-7}{-7} x=\frac{-91}{-7}[/tex] any number divided by itself like in -7/-7 =1

x=13

0.5x + 1.75 = 10 subtract 1.75 from both sides

0.5x +1.75-1.75 =10 -1.75

0.5x = 8.25 divide by 0.5 both sides

[tex]\frac{0.5}{0.5} x=\frac{8.25}{0.5}[/tex]

x=16.5

0.75h +3=12 subtract 3 from both sides

0.75h = 12-3 divide both sides by 0.75

[tex]h= \frac{9}{0.75}[/tex] = 12

= 24000 x ( 1 + 0.0275 ) ^ 4= 26750.91
26750.91 - 24000 = 2750.90
i’m sorry if it’s wrong

Answer:

(Use the attached formula)

24,000 for 4 years (48 months) at 2.75% interest

We divide rate by 1,200 which equals 0.0022916667

Monthly Payment = 0.0022916667 + {(0.0022916667 / [(1.0022916667)^48 -1]} * 24,000

Monthly Payment = 0.0022916667 + (0.0022916667 /  (1.1161375981  -1) * 24,000

Monthly Payment = [0.0022916667 + (0.0022916667 /  0.1161375981 ] * 24,000

Monthly Payment = [0.0022916667 +  0.0197323411 ] *24,000

Monthly Payment = 0.0220240078  * 24,000

Monthly Payment = 528.5761872  = 528.58 (rounded)

Exact form: x = [tex]\frac{10.8}{sin(57)}[/tex]

Rounded to the Nearest Tenth: x = 12.9

Step-by-step explanation:

In the right-angled triangle, we can use the trigonometry functions to find the length of a side or a measure of an angle

In the given figure

∵ ∠C is the right angle

ΔACB is a right triangle

m∠B = 57°

AC = 10.8

∵ AC is the opposite side of ∠B

∵ AB is opposite to the right angle

∴ AB is the hypotenuse

AB = x

→ We can use the function sine to find x

∵ sin∠B = [tex]\frac{opposite}{hypotenuse}[/tex]

∴ sin∠B = [tex]\frac{AC}{AB}[/tex]

→ Substitute the values of ∠B, AC, and AB in the rule of sine above

∴ sin(57°) = [tex]\frac{10.8}{x}[/tex]

→ By using cross multiplication

∵ x × sin(57°) = 10.8

→ Divide both sides by sin(57°)

x = [tex]\frac{10.8}{sin(57)}[/tex]

x = 12.87752356

→ Round your answer to the nearest tenth

x = 12.9

Exact form: x = [tex]\frac{10.8}{sin(57)}[/tex]

Rounded to the Nearest Tenth: x = 12.9

Answer:

x+7 ≤ 20

Just take it step by step:

seven more than a number is a number plus 7 (x+7)- keep in mind we dont know what the number is so we use x to represent the number.

it then says it's equal to at most 20.

This means that it cant equal anything above 20 since 20 is the max. Therefore, it must be 20 and below that x+7 equals

Complete Question

Suppose that the amount of time teenagers spend weekly working at part-time jobs is normally distributed with a standard deviation of 40 minutes. A random sample of 15 teenagers was drawn and each reported the amount of the time spent at part-time jobs (in minutes). These are listed here 180, 130, 150, 165, 90, 130, 120, 60, 200, 180, 80, 240, 210, 150, 125. Determine the 95% confidence interval estimate of the population mean.

Answer:

The 95% confidence interval is  [tex] 127.09  <  \mu <  167.57 [/tex]

Step-by-step explanation:

From the question we are told that

   The standard deviation is  [tex]\sigma = 40[/tex]

   The sample size is  n  = 15

     The data given is   180, 130, 150, 165, 90, 130, 120, 60, 200, 180, 80, 240, 210, 150, 125

Generally the sample mean is mathematically represented as

             [tex]\= x = \frac{ \sum x_i}{n }[/tex]

=>          [tex]\= x = \frac{ 130 + 150 + \cdots + 125 }{ 15 }[/tex]

=>          [tex]\= x = 147.33[/tex]

From the question we are told the confidence level is  95% , hence the level of significance is    

      [tex]\alpha = (100 - 95 ) \%[/tex]

=>   [tex]\alpha = 0.05[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.96[/tex]

Generally the margin of error is mathematically represented as  

      [tex]E = Z_{\frac{\alpha }{2} } *  \frac{\sigma }{\sqrt{n} }[/tex]

=>     [tex]E = 1.96  *  \frac{40}{\sqrt{15} }[/tex]

=>     [tex]E =20.24 [/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex] 147.33 -20.24<  \mu <  147.33 + 20.24 [/tex]

      [tex] 127.09  <  \mu <  167.57 [/tex]

Find the value of n. 103 × n = 630 The value of n is .

Answers

Answer:

The answer would be n=6.11

Step-by-step explanation:

The answer would be n=6.125

It is asking for the value of a variable, in this case, the variable is "n" and it can be found by isolating it on one side of the equation using basic mathematical operations such as division, multiplication, addition and subtraction. The question is asking to find the value of n, by solving the equation 103*n = 630.

To find the value of n, we can divide both sides of the equation by 103.

103 * n = 630

n = 630/103

n = 6.125

Therefore, The value of n is 6.125
