Which function is a shrink of the exponential growth function shown on the graph?

MA_775_DIABLO [31]

For exponential functions
y=ab^x,
where
a is the scale vertical stretch factor,
b is the base, and
x the exponent (also independent variable)

It is a know fact that if the scale factor (1/2 or 2 in the answer choices) is positive, the graph is increasing if the base (3 or 1/3) is greater than 1.
This means that the base cannot be equal to 1/3. This eliminates choices 3 and 4.

Next, for a base greater than 1 (3>1), and the scale factor positive, it is a dilation (image gets bigger) if the scale factor is greater than 1. This eliminates the first choice where a=2.

This leaves us with the second choice where a=1/2, b=3, which is a shrink of the given exponential base function.

A person’s retirement account of $30,000 earns 4% each year. Which value would represent the base of the exponential function th

vivado [14]

Well, your probably gonna not go with 30,000 because it stands out like a sore thumb. and 4% is = to .04 So that would be my likely guestimation. 1.04 is probably the answer. in high school you would do 30,000(1+.04/1
)^1*1

and if you were to simplify
30,000(1+.04)
or
30,000(1.04)
So i would say 1.04 is the answer

Answer: Step-by-step explanation:

Firstly lets start off by what an integer is

an integer is any whole number with positive and negative signs but zero is neither positive or negative or carries a sign

example of whole number

0, 1, 2, 3 , 4, 5, 6, 7, …

example of positive and negative integers

1,2,3,4,5,6,… positive integers

-1,-2,-3,-4,-5,-6,… negative integers

“+” This symbol is a plus/positive sign

“-” This symbol is a minus/negative sign

Answer:

3/2x + 1/2 = y

Step-by-step explanation:

3x=2y-1

Solve for y

Add 1 to each side

3x+1 = 2y

Divide by 2

3/2x + 1/2 = y

you invest 1600 in an account that pays an interest rate of 6.5%, what is your balance after 6 years and round your answer to th

brilliants [131]

Assuming Interest is compounded yearly:
Every year, the principal is multiplied by 1.06
Therefore, we multiply 1600 by 1.06⁶, or multiply by 1.06 six times
1.06⁶ = 1.4185

1600 * 1.4185 = 2,269.63
