2 answers:

3 0

Answer:

THE THIRD ONE

Step-by-step explanation:

the equation: An=A1+d(n-1)

plug in the numbers

3 0

A1 = 5
d = a2-a1 = 2-5 = -3

$a(n) = a + (n - 1)d \\ a(n) = 5 + (n -1) - 3 \\ a(n) = 5 - 3(n - 1)$

Answer will be C.

Answer:

Concept: Modeling expressions

We are given the equation
$200 - 16 {t}^{2}$
We want to find the time after 0.75 seconds given that t is represented in seconds.
Hence we do
$200 - 16(0.75)^{2}$
Hence we get the answer to 191 feet
