If $1,120 is invested at an interest rate of 15% per year and is compounded continuously, how much will the investment be worth in 7 years? use the continuous compound interest formula: a = pert.
$565.91
$1,131.82
$1,244.00
$3,200.57

3200.57

Step-by-step explanation:

Step 1: Write the data

Principal (P) = 1120

Rate (R) = 15%

Time = 7 years

Step 2: Write the formula

A = (Principal x e)^rate x time

Step 3: Apply the formula

A = Pe^rt

A = 1120e^0.15*7

A = 3200.57

Therefore, the investment will be worth $3200.57 in 7 years.

!!

 $3,200.57

Step-by-step explanation:

Given : Principal amount invested : P= $ 1,120

Rate of interest : r= 15% = 0.15

Time: t = 7 years

The continuous compound interest formula:-

Substitute all the values in the formula , we get

Hence, the compounded amount after 7 years = $3200.57

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

answer: r there any options?
