Peter puts 8000 into a savings account that pays 6% interest, compounded continuously. After 5 years, Peter will have ( $)

guajiro [1.7K]

We have to calculate the amount of money Peter will have in his account after 5 years. Formula for the amount after t years with interest compounded continuously : A = P * e ^(rt)
We know that r = 0.06, t=5, e = 2.71 and p= $8,000
A = 8,000 * 2,718 ^(0.06 * 5) = 8,000 * 2,718 ^ (0.3) = 8,000 * 1.3488158 = 10,798.53 so the answer is 10,798.53

which order pair is a solution of the equation? y-4=7(x-6) A. only (5,4) B. only (6,5) C. both (5,4) and (6,5) D. neither

Svet_ta [14]

Answer:

option D. Neither

Step-by-step explanation:

y-4=7(x-6)

using (5,4):

4-4=7(5-6)

0=7(-1)

0=-7

using (6,5):

5-4=7(6-6)

1=7(0)

1=0

so option D is the answer

How to graph 14x+18y=126

Burka [1]

We need to rearrange this into $y=my+c$
Subtract 14x from both sides
$18y=-14x+126$
Divide both sides by 2
$9y=-7x+63$
Divide both sides by 9
$y=\frac{-7x+63}{9}=\frac{-7x}{9} +\frac{63}{9}$
Plot the point (0, 63/9)
Then pick some x values and put them into the equation to find the respective y values
Then plot those points
Finally join up those points
