Answer:

Jake has $11.29 dollars left.

Step-by-step explanation:

To find the answer, we will add up $5 + $6.50 + $7.21 and we get $18.71. Now subtract $30 from 18.71, which is $11.29. Therefore, Jake has $11.29 dollars left.

krek1111 [17]

Answer:

The answer is option 1.

Step-by-step explanation:

You have to apply Gradient formula :

$m = \frac{y2 - y1}{x2 - x1}$

$let \: (x1 \: , \: y1) \: be \: ( - 2 \: , \: 0)$

$let \: (x2 \: , \: y2) \: be \: (0 \: , \: 4)$

$m = \frac{4 - 0}{0 - ( - 2)}$

$m = \frac{4}{2}$

$m = 2$

if you deposit $8000 into an account paying 9% annual interest compunded semi anually how long will it take for your money to do

Anna007 [38]

Answer:

7.87 years

Step-by-step explanation:

#First we determine the effective annual rate based on the 9% compounded semi annual;

$i_m=(1+i/m)^m-1\\\\=(1+0.09/2)^2-1\\\\=0.09203$

#We then use this effective rate in the compound interest formula to solve for n. Given that the principal doubles after 2 yrs:

$A=P(1+i)^n\\\\A=2P, i=i_m\\\\16000=8000(1.09203)^n\\\\2=1.09203^n\\\\n=\frac{log \ 2}{log \ 1.09203}\\\\=7.87324\approx7.87 \ yrs$

Hence, it takes 7.87 years for the principal amount to double.
