Answer:

347 is the initial spider population

Step-by-step explanation:

y = ab^x

is the formula for exponential growth and decay

a = the initial value

b is the growth or decay rate

b>1 it is the growth rate (b-1) is the percent

0<b<1 it is the decay rate (1-b) is the percent

y = 347(1.2)^x

347 is the initial spider population

(1.2-1) = .2 = 20 % growth rate

Plug all three answers in and see which one does not equal 0
A: 2(1)+3(1)-7-12≠0
B: 2(6)+0-0-12=0
C: 2(3)+3(3)-3-12=0

So A. I don't know why it says two (?) points?

Express 20% as a fraction in its lowest form? Thanks

Hello!

✧･ﾟ: *✧･ﾟ:* *:･ﾟ✧*:･ﾟ✧

❖ 20% as as a fraction in lowest terms is $\frac{1}{5}$

Percents are out of 100% so write 20% out of 100% as a fraction:

$\frac{20}{100}$

Both the numerator and denominator can be divided by 20 so once divided, you get $\frac{1}{5}$
