Answer:

≈ $937

Step-by-step explanation:

to answer this, we have to use the compound interest formula which is:

A = P(1 + r/n)^nt

the meanings of each variable are:

A = result

P = principal amount

r = rate (in decimal form)

n = the number of compound periods (eg: annually, quarterly, etc)

t = time

in the word problem, we need to solve for A. we are given P, r, n, and t.

P = 800

r = 0.02 also known as 2%

n = 1 keyword being <em>annually</em> which is equal to the value of 1

t = 8

we can plug these values into the formula:

A = 800(1 + 0.02/1) $^(^1^)^(^8^)$

we can use a calculator to calculate this easier but ill break it down:

A = 800(1 + 0.02/1) $^8$

A = 800(1.02) $^8$

A = 800(1.17165938)

A ≈ 937.327

we can round 937.327 to the nearest dollar which is $937

Carl would have earned $937 over the course of 8 years

Which function below has the lowest y-intercept?

Arte-miy333 [17]

If f(x) is given with points (0,5) and (4,3), it can be easily plotted in a coordinate system (see .jpeg image in attachment).
If g(x) is a function defined by text:
<em>Kyle started the summer having read 3 books but plans to read 6 books per month over the summer.
</em>Then, g(x) is given with:
g(x) = 6*x+3 (3 books read already, and 6 books will be read each month).
h(x) is already given with:
h(x)=3*x+4
These all three functions are plotted in coordinate system (see the .jpeg image), and it can be seen that the lowest y-intercept has function g(x), and it is the value of 3 on y-axis. Others have 4 (h(x)) and 5 (f(x)).
