Does the function model exponential growth or decay? f(t)=1/4⋅4^t

Mathematics
1 answer:
yarga [219]3 years ago
6 0

Answer:

This is an exponential decay

Because the base of the exponent is 1/4.4 which is less than 1

Step-by-step explanation:

What is exponential growth?

when the base of our exponential is bigger than 1, which means those numbers get bigger.

What is exponential decay?

when the base of our exponential is in between 1 and 0 and those numbers get smaller.

Review the bar graph below:
Scrat [10]

Answer:

B. 12.5%

Step-by-step explanation:

Add all the hours together to get 20. We make the assumption that 20 is 100% since it is our output value. We next represent the value we seek with x. From step 1, it follows that 100%=20. In the same vein, x%=2.5.This gives us a pair of simple equations:

100%=20(1)

x%=2.5(2)

By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS  (left hand side) of both equations have the same unit (%); we have

\frac{100}{x}=\frac{20}{2.5}

Taking the inverse (or reciprocal) of both sides gives us this:

\frac{x}{100} =\frac{2.5}{20}

>> x=12.5\%  

Therefore, 2.5 is 12.5% of 20.

295 X 3 =<br> What is the distributive property of multiplication
frosja888 [35]

Answer:

295 x 3 = 885

The distributive property is when you distriute numbers if they are getting multiplied by the same number.

Example:

Original Equation: A(B+C)

Distribute the equation so that B and C are by itself.

New Equation: AxB + AxC

This is distributive property.
