What is the effect on the graph of f(x) = x2 when it is transformed to h(x) = 322 – 13
O A. The graph of f(x) is horizontally compressed by a factor of 8 and
shifted 13 units down.
O B. The graph of f(x) is vertically compressed by a factor of 8 and
shifted 13 units to the right.
O C. The graph of f(x) is horizontally stretched by a factor of 8 and
shifted 13 units to the right.
D. The graph of f(x) is vertically compressed by a factor of 8 and
shifted 13 units down.

i think it is c, not positive though

im not sure

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
