Maria invests $6,154 in a savings account with a fixed interest rate of 8% compounded continuously. What will the account balanc

Vitek1552 [10]

Answer:

$13,695.98

Step-by-step explanation:

We can use the continuous compound interest formula to solve:

$A = Pe^{rt}$

P = principal amount

r = interest rate (decimal)

t = time (years)

First, lets change 8% into a decimal:

8% -> $\frac{8}{100}$ -> 0.08

Now, lets plug in the values:

$A=6,154e^{0.08(10)}$

$A=13,695.98$

The account balance after 10 years will be $13,695.98

If (a,b) is an ordered pair for x-y=5, is (b,a) also a solution?

alina1380 [7]

The answer is no. Because solution (a,b) means x=a, y=b.and we have a-b=5. And (b,a) would mean x=b and y=a but then x-y=b-a=-(a-b)=-5≠5. So the pair (b,a) is not a solution.

Differentiate with respect to x : 2xe^x

Gnom [1K]

$\\ \sf\longmapsto \dfrac{d}{dx}2xe^x$

Apply product rule

$\\ \sf\longmapsto \dfrac{d}{dx}2x(e^x)$

$\\ \sf\longmapsto 2x\dfrac{d}{dx}e^x+e^x\dfrac{d}{dx}2x$

$\\ \sf\longmapsto 2xe^x+2e^x$

$\\ \sf\longmapsto 2e^x(x+1)$
