How much will Chris’s investment account be worth in five years if he invests $5,000 with 2.8% interest?

vovikov84 [41]

Answer:

$\$5,700$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=5\ years\\ P=\$5,000\\r=0.028$

substitute in the formula above

$A=\$5,000(1+0.028*5)$

$A=\$5,000(1.14)=\$5,700$

3. Solve each of the following constant coefficient ordinary differential equations: (10 pts] a) y"+ 3y'- 28y = 0

eduard

Answer:

$y(t) = C_1e^{4t} + C_2e^{-7t}$

Step-by-step explanation:

We are given the following information in the question:

$y''+3y'-28y = 0$

This can be written as:

$(D^2 + 3D - 28)y = 0$

The auxiliary equation obtained is:

$m^2+ 3m - 28 = 0\\ m^2 + 7m - 4m - 28 = 0\\m(m+7)-4(m+7)=0\\(m-4)(m+7)\\m = 4, m = -7$

Thus, the general solution of the equation is:

$y(t) = C_1e^{4t} + C_2e^{-7t}\\\text{where } C_1, C_2 \text{ are constants}$

X - 9 = 21<br><br> What does x =

Slav-nsk [51]

Answer:

x=30

Step-by-step explanation:

You have to isolate for x. This means you need to somehow get x on one side of the equation all alone. In this case it is x-9=21 which means some unknown number x with 9 subtracted from it is equal to 21. When we bring the -9 over to the other side to get the x all alone, we have to switch the sign of the -9 so it becomes +9. This means x=21+9, and if you add that you'll get 30!
