A, C, and E

Any numbers that, when multiplied, produce the number 7.82 have the same value as 2.3 * 3.4. Some numbers include 2 * 3.91 and 17 * 0.46. A, C, and E, when simplified all equal 7.82

Helen [10]

Answer:

127,000\ members

Step-by-step explanation:

In this problem we have an exponential function of the form

f(x)=a(b)^{x}

where

a is the initial value

b is the base

The base is equal to

b=1+r

r is the average rate

In this problem we have

a=23,000 members

r=5%=5/100=0.05

b=1+0.05=1.05

substitute

f(x)=23,000(1.05)^{x}

x ----> is the number of years since 1985

How many members will there be in 2020?

x=2020-1985=35 years

substitute in the function

f(x)=23,000(1.05)^{35}=126,868\ members

Round to the nearest thousand

126,868=127,000\ members

Coner earns $9 an hour for yard work.He earned $29.25.how much does he earn every minute.
makvit [3.9K]

He earns $0.15 every minute.  There are 60 minutes every hour and you are trying to found out how much money he is making in 1 minute, so you divide 9 by 60, which will give you the decimal number 0.15. The $29.25 was just a little extra information to try to brush you off.
