I need help I will give BRAINLEST
GREYUIT [131]

Answer:

25%

Step-by-step explanation:

To solve this, we can use the percent change formula shown in the picture attached below. x_{2} is the new value, x_{1} is the old value, and C represents the change. For this problem, 80 is the new value and 64 is the old value. Let's plug those numbers into the formula and solve for the percent change:

C = \frac{(80-64)}{64} \\ × 100

C = \frac{16}{64} ×100

C = 0.25 ×100

C = 25%

Thus, the answer is 25%.

HELP ASAP PLEASE!!! This is a written response
o-na [289]

Answer:

Exponential decay.

Step-by-step explanation:

The magnitude of the base (also known as the "common factor") tells us whether a given exponential equation represents growth or decay.

Standard equation for expo. growth:  y = 3(b)^x, where b is the base.

If 0<b<1, we have expo. decay; if 1<b, we have expo. growth.

Thus, y = 3(0.5)^x represents expo. decay.
