Answer:
A. −2(x − 7)2 + 118; x = $7
Step-by-step explanation:
The expression −2x² + 28x + 20 represent the store weekly profit in dollars, where x represents the price of a new video game.
let f(x) = −2x² + 28x + 20
We need to rewrite this quadratic function in the vertex form.
f(x) = −2(x² - 14x) + 20
f(x) = −2(x² - 14x +49) - {-2(49) + 20}
f(x) = −2(x² - 14x +49) + 98 + 20
f(x) = −2(x² - 7)² + 118
The equivalent expression that reveals the video game price that produces the highest weekly profit is -2(x-7)^2+118 and the price is $7
R = 32 / 2 = 16
Pie = 3.14
Area of circle = pie x r^2
= 3.14 x 16^2 = 803.84
Answer:
The area of the base is 80 in². 80 square inches.
Step-by-step explanation: V = b×h
Divide the volume by the height to find the area of the base.
400 ÷ 5 = 80
