If f(x)=8-10x and g(x)=5x+4, what is he value of (fg)(-2)
Lana71 [14]

Answer:

168

Step-by-step explanation:

We would like to multiply these two expressions together and then substitute -2 in for x to solve.

f(x) * g(x) = (8 - 10x) * (5x + 4)

We will use FOIL (first, outer, inner last):

(8 - 10x) * (5x + 4) = 8 * 5x + 8 * 4 + (-10x) * 5x + (-10x) * 4

Combining terms, we get:

f(x) * g(x) = 32 - 50x²

Plug -2 in for x:

32 - 50 * (-2)² = 32 - 50 * 4 = 32 - 200 = -168

The answer is thus 168.

A particle moves along the x-axis so that its velocity in feet per second at time x, in seconds, is modeled by the quadratic fun
Katyanochek1 [597]

For this case we have the following equation:

y = 2x ^ 2 - 10x + 12

Where, we have the following variables:

x: time in seconds

y: speed in feet per seconds

For the initial velocity, we evaluate x = 0 in the given equation:

y = 2 (0) ^ 2 - 10 (0) + 12\\y = 12

Therefore, the initial speed is 12 feet per second.

Answer:

The particle's initially velocity is 12.
