Kisachek [45]

The method that results in more money after 2 years is Peggy's investment.

<h3>Which method results in more money in 2 years?</h3>

The formula for calculating the future value of an investment:

FV = P (1 + r)^nm

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

Future value of Larry's investment: $350 x [1 + (0.04/4)]^(4 x 2) = $379

Future value of Peggy's investment: $350 x [1 + (0.06/12)]^(12 x 2) = $394.51

A triangular-shaped deck has one side that is 4 feet longer than the shortest side and a third side that is 4 feet shorter than

Inessa05 [86]

Answer:

The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.

Step-by-step explanation:

Assuming that the shortest side of this triangle has a length of "x" feet, then one side is "x + 4" feet and the third is "2*x - 4" feet. Since the perimeter of the deck is 80 feet, then the sum of the length of these sides should be equal to that.

$x + x + 4 + 2*x - 4 = 80\\4*x = 80\\x = \frac{80}{4} = 20 \text{ feet}\\$

The shortest side is 20 feet, the second side is 24 feet and the third side is 36 feet.

Is (0,0) a solution to this system y> x2+x-4 y <x2+2x+1

Aliun [14]

Answer:

Yes, the ordered pair (0,0) is a solution of the system

Step-by-step explanation:

we have

$y\geq x^{2}+x-4$ ----> inequality A

$y < x^{2} +2x+1$ ----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities

<u>Verify</u>

For x=0,y=0

<em>Inequality A</em>

$0\geq (0)^{2}+0-4$

$0\geq -4$ ----> is true

The ordered pair satisfy inequality A

<em>Inequality B</em>

$0 < (0)^{2} +2(0)+1$

$0 < 1$ ----> is true

The ordered pair satisfy inequality B

therefore

The ordered pair (0,0) is a solution of the system
