Answer:

any number in the y axis, like (y = 1) etc. I don't know if you wrote the question correctly because if it's just (y = -1/5) the slope would be zero.

Step-by-step explanation:

lol wrote it in the wrong place

You invest $5,000 into an account where interest compounds continuously at 3.5%. How long will it take your money to double? Rou

salantis [7]

Answer:

20 years

Step-by-step explanation:

<u>Continuous Compounding Formula</u>

$\large \text{$ \sf A=Pe^{rt} $}$

where:

A = Final amount
P = Principal amount
e = Euler's number (constant)
r = annual interest rate (in decimal form)
t = time (in years)

Given:

A = $10,000
P = $5,000
r = 3.5% = 0.035

Substitute the given values into the formula and solve for t:

$\sf \implies 10000=5000e^{0.035t}$

$\sf \implies \dfrac{10000}{5000}=e^{0.035t}$

$\sf \implies 2=e^{0.035t}$

$\sf \implies \ln 2=\ln e^{0.035t}$

$\sf \implies \ln 2=0.035t\ln e$

$\sf \implies \ln 2=0.035t(1)$

$\sf \implies \ln 2=0.035t$

$\sf \implies t=\dfrac{\ln 2}{0.035}$

$\implies \sf t=19.80420516...$

Therefore, it will take 20 years (to the nearest year) for the initial investment to double.

Alisha has a $15,000 car loan with a 6 percent interest rate that is compounded annually. How much will she have paid at the end

Harlamova29_29 [7]

6 percent intrest per year for 5 years I think is the same as 30 percent for 5 years
so $15,000 x .3 is $4500
$15,000 + $4500 = $19,500
not 100 percent sure if this is correct but I think its right.
Sorry if I am wrong not 100% sure.
