Laura invest $300 into an account with an interest rate of 4% compounded annually. Write an exponential function to represent th

LiRa [457]

The exponential function that represents the future value of the investment is $300(1.04)^t.

<h3>What is the exponential function?</h3>

The exponential function that can be used to determine the future value of the investment is:

FV = P (1 + r)^nm

FV = Future value
P = Present value
R = interest rate
m = number of compounding
N = number of years

$300(1.04)^t.

Where t represents number of years

Solve Systems by Substitution 2x+5y=-3 x+8y=4 and 2x+y=7 x-2y=-14

ASHA 777 [7]

2x + 5y = -3 ⇒ 2x + 5y = -3
1x + 8y = 4 ⇒ 2x + 16y = 8
 -11y = -11 
 -11 -11
 y = 1
 2x + 5(1) = -3
 2x + 5 = -3
 -5 -5
 2x = -8
 2 2
 x = -4
 (x, y) = (-4, 1)

2x + 1y = 7 ⇒ 2x + 1y = 7
1x - 2y = -14 ⇒ 2x - 4y = -28
 5y = 35
 5 5
 y = 7
 2x + 7 = 7
 -7 -7
 2x = 0
 2 2
 x = 0
 (x, y) = (0, 7)

A man hiked a distance of 9 miles into the country. He rode back in a car along the same route at the rate of 27 mph. If the ent

Sophie [7]

Let n be the man's walking rate. Then:
9/n+9/27=3&1/3
243+9n=90n
243=81n
n=3
The man's walking rate was 3 mph
