If m(x) = x3 and n(x) = find the function value, if possible.(m – n)(-5)

The stopping distance of a car varies directly as the square of the speed of the car. If a car traveling 40 mph has a stopping distance of 109 ft, find the stopping distance of a car that travels 25 mph. (Round the answer to one decimal place.)

Find the and of the function.f (x) = 6×2 – 60

Find the resulting interval. (-∞, 5] ∩ [-1, 12)

Identify the restricted values for the equation. – 14 = 0

The cost in dollars of producing x toy cars is C(x) = 2.2x + 1. The revenue for selling x toy cars is R(x) = 6.45x. To calculate profit, subtract the cost from the revenue.a. Write and simplify a function P that represents profit in terms of x.b. Find the profit of producing 40 toy cars.

Approximate the function value from the graph.(f + g)(-4)

Find the x- and y- intercepts of the function.g(x) = -4x – 14

Find an expression that represents the perimeter of the rectangle (assume that x > 0)

The figure shows the path of a ray of light as it travels through ethyl alcohol and crosses a boundary into an unknown medium. The angles of incidence and refraction are 62° and 55.6°, respectively. What is the speed of this ray of light as it travels through the unknown medium?
