Answer: x + 5

<u>Step-by-step explanation:</u>

f(x) = x² + 5 g(x) = √x

f(g(x)) = (√x)² + 5 (replaced the x in f(x) with √x)

= x + 5

Write the explicit formula that represents the geometric sequence -2,8,-32,128.

Dmitriy789 [7]

Answer:

$a_{n}$ = - 2 $(-4)^{n-1}$

Step-by-step explanation:

The n th term ( explicit formula ) for a geometric sequence is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

Here a = - 2 and r = 8 ÷ - 2 = - 4, thus

$a_{n}$ = - 2 $(-4)^{n-1}$

The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a,

Elenna [48]

Answer:

(f-v)/a = t

Step-by-step explanation:

f = v + at

Subtract v from each side

f-v = v-v + at

f-v = at

Divide each side by a

(f-v)/a = at/a

(f-v)/a = t
