Answer:

C) horizontal reflection over y-axis and horizontal stretch

Step-by-step explanation:

1a- A vertical reflection over the x-axis occurs when a function f(x) is transformed into f(-x)

1b- A horizontal reflection over the y-axis occurs when a function f(x) is transformed into -f(x)

2a- A function is being compressed if f(x) is multiplied by a positive factor k: k f(x) with k>1

2b- A function is being stretched if f(x) is multiplied by a positive factor k: k f(x) with k

In our problem, the original function f(x) is:

- Multiplied by 1/2, so by a factor which is smaller than 1, so we are in case 2b

- Transformed from f(x) into -f(x) (due to the negative sign in front of it), so we are in case 1b

So, overall, we had a horizontal reflection over the y-axis and a stretch of the function.

Answer:

Step-by-step explanation:

A, B and C must be real numbers, and A and B are not both zero (which would cause division by zero in the calculation of the slope).

Phil's height is 51.2 cm, suzanne's height is 5'4", and suzanne's shadow lengthat gobblers knob is 76.2
8090 [49]

Answer:

P_1 = 24cm

Step-by-step explanation:

Represent:

Phil's height with P

Suzanne's height with S

Phil's shadow with P1

Suzanne's shadow with S1

So, we have:

P = 51.2cm

S = 5'4"

S_1 = 76.2cm

Required

Calculate the length of Phil's shadow --- Missing part of question

To do this, we make use of the following equivalent ratio.

P:S = P_1 : S_1

Convert S = 5'4" to cm

S = 5ft\ 4in

S = (5*30.48+ 4*2.54)cm

S = 162.56cm

Substitute values for P, S and S1

51.2cm : 162.56cm = P_1 : 76.2cm

Express as fraction

\frac{51.2cm}{162.56cm} = \frac{P_1 }{ 76.2cm}

Make P1 the subject

P_1 = 76.2cm * \frac{51.2cm}{162.56cm}

P_1 = 76.2cm * \frac{51.2}{162.56}

P_1 = \frac{76.2cm * 51.2}{162.56}

P_1 = \frac{3901.44cm}{162.56}

P_1 = 24cm

<em>Hence, the length of Phil's shadow is 24 cm</em>
