Please help. The drop down menus are either exponential growth or decay. Promise brainliest

Problem 1

Explanation:

The base of the exponent 1.25 is in the form 1+r with r = 0.25

r = 0.25 converts to 25%

The fact that r is positive indicates we have growth.

Problem 2

Explanation:

Rewrite 5^(-t) as (1/5)^t. The negative exponent has us apply the reciprocal of the base. The rule is x^(-k) = (1/x)^k = 1/(x^k)

Then we write 1/5 as 0.2 and set it equal to 1+r. Solve for r

1+r = 0.2

r = 0.2-1

r = -0.8

The negative r value tells us we have decay.

Problem 3

This value is approximate

Explanation:

(1.20)^(t/11) = (1.20^(1/11))^t

(1.20)^(t/11) = (1.0167128)^t use calculator, this is approximate

Set 1.0167128 equal to 1+r and solve for r

1+r = 1.0167128

r = 1.0167128-1

r = 0.0167128

r = 1.67128%

r = 1.7%

The positive r value tells us we have growth.

Problem 4

Explanation:

Set the base 0.63 equal to 1+r and solve for r

1+r = 0.63

r = 0.63-1

r = -0.37

r = -37%

The negative r value indicates decay.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
