the exponential function f(x) =
he invest $1000 for 5, 10, 15 years
5 years,
To find the amount of money he have , we plug in 5 for x and find out f(5)
f(x) =
f(5) =
= 1762.34
The amount of money he have after 5 years is 1762.34
10 years,
To find the amount of money he have , we plug in 10 for x and find out f(10)
f(10) =
= 3105.85
The amount of money he have after 10 years is 3105.85
15 years,
To find the amount of money he have , we plug in 15 for x and find out f(15)
f(15) =
= 5473.57
The amount of money he have after 15 years is 5473.57
f(5) = 1762.34
f(10) = 3105.85
f(15) = 5473.57
Answer:
a)

b)

Step-by-step explanation:
The reciprocal of a number is the inverse of the number




Your answer is C
It's hard to describe I did it all in my head but please trust me that C is correct
23) It is right angle triangle, so the sum of acute angle must be equal to 90
sum of ratio units = 2+7 = 9
value of 1 unit = 90/9 = 10
measures of angle would be 2(10) & 7(10) = 20 & 70
Measure of smaller angle is 20
24) It is only graphical work. You have to do it on your own cause I can't show you here, sorry!!
