Answer:
Step-by-step explanation:
An exponential function is of the form

where a is the initial value and b is the growth/decay rate. Our initial value is 64. That's easy to plug in. It goes in for a. So the first choice is out. Considering b now...
If the rate is decreasing at .5% per week, this means it still retains a rate of
100% - .5% = 99.5%
which is .995 in decimal form.
b is a rate of decay when it is greater than 0 but less than 1; b is a growth rate when it is greater than 1. .995 is less than 1 so it is a rate of decay. The exponential function is, in terms of t,

Hi there! :)
<u>Answer:</u>
The area of the carpet is <u>3m²</u>.
Step-by-step explanation:
First off, the formula to calculate the area of a rectangle is this: A = L × W
Where "A" is the area, "L" the length and "W" the width.
Now that you have that, replace all the information you know in the equation in order to find the value of "A", which is what we are looking for:
- Just keep in mind that 1 1/2 is the same thing as 1.5
- The term "wide" is used to give the "width"
- The term "long" is used to give the "length"
A = L × W
A = 2 × 1.5
<u>A = 3</u>
There you go! I really hope this helped, if there's anything just let me know! :)
Hi Desperate!
anyways the equation for constant variation is y=kx
3y=6x is it, but we don't want the 3.
so we divide on both sides to cancel out the 3.
y=2x
