Answer:

D. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp

Step-by-step explanation:

f(x) = x²- 10x + 25

We can factor this.

What 2 numbers multiply to 25 and add to -10

-5 *-5 = 25

-5+-5 = -10

f(x) =(x-5) (x-5)

Using the zero product property, we know that it will cross the axis at x=5

At 5 seconds f(x) =0. This means the height is zero at 5 seconds

Answer:

Hello,

This sequence is geometric with a ratio of -3

the first term is 6

Step-by-step explanation:

$u_1=6\\u_2=-18=6*(-3)=u_1*(-3)\\u_3=54=-18*(-3)=u_2*(-3)=u_1*(-3)^2\\u_4=-162=u_3*(-3)=u_1*(-3)^3\\\\...\\u_{n+1}=u_1*(-3)^n\\\\\displaystyle \sum\limits^\infty _{i=1}u_i = \lim_{n \to \infty} \sum\limits^n _{i=1}u_1*(-3)^{i-1}\\=6*\lim_{n \to \infty} \sum\limits^\infty _{i=1}(-3)^{i-1}\\=6*\frac{1-(-3)^n}{1-(-3)} \\=\dfrac{3}{2} *({1-(-3)^n)\\$

serie does not converge.
