Trever invested $10,000 in an account that earns 8.5%
interest that is compounded monthly.
(a) Write an exponential model for the balance of the
account.
(b) Determine the amount of money in the account
after 15 years.

Answers

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Trever invested $10,000 in an account that earns 8.5% interest that is compounded monthly.

First, we need to calculate the monthly interest rate:

i= 0.085 / 12= 0.00708

Now, to calculate the future value of the investment, we need to use the following formula:

FV= PV*(1+i)^n

PV= initial investment

i= interest rate

n= number of periods

In this case:

FV= 10,000*(1.00708^n)

Finally, for 15 years:

n= 15*12= 180 months

FV= 10,000*(1.00708^180)

FV= $35,605.31

If f(x)=3x-1 and g(x)=x2+2 what is f[g(x)]

Answers

Answer:

Value of f[g(x)] = 3x² + 5

Step-by-step explanation:

Given:

f(x) = 3x - 1

g(x) = x² + 2

Find:

Value of f[g(x)]

Computation:

f(x) = 3x - 1

g(x) = x² + 2

So,

f[g(x)] = 3(x² + 2) - 1

f[g(x)] = 3x² + 6 - 1

Value of f[g(x)] = 3x² + 5

Nancy and Evan are each writing a 6-page essay. Nancy completed 4/6 of her essay in the morning and 2/6 of her essay in the afternoon.

PLEASE HELP AGAIN!! Max deposited $4,008 in a savings account with simple interest. Four years later, he had earned $641.28 in interest. What was the interest rate?​

Answers

Answer:

4%

Step-by-step explanation:

For simple interest, the equation is I = PRT, where I is the interest, P is the principal/amount invested, R is the rate as a decimal, not percentage, and T is time in years.

641.28 = (4008)(r)(4)

641.28 = 16,032r

r = 0.04 = 4%

Which statements are correct about the average rate of change for the function f(x) = x2 + 9x + 18 ?

Answers

Answer:

Presumably this is a multiple choice question, and without seeing the potential answers, we can't tell you which ones are correct.

A few things can however be said about this function:

1) It describes a parabola that extends upward infinitely.  We can see this because it's in the classic format ax² + bx + c, and all terms are positive.

2) We can find the x-intercepts by solving for zero.  In this case we can do that by factoring it:

x² + 9x + 18 = 0

x² + 3x + 6x + 18 = 0

x(x + 3) + 6(x + 3) = 0

(x + 6)(x + 3) = 0

So the x intercepts occur at (-6, 0) and (-3, 0)

3) we can find its vertex by taking its derivative and solving for zero:

f'(x) = 2x + 9

0 = 2x + 9

x = -4.5

We can then plug that coordinate into the original function to find the y coordinate:

f(x) = x² + 9x + 18

f(-4.5) = 20.25 - 40.5 + 18

= -2.25

So the vertex is at (-4.5, -2.25)

4) As mentioned, the derivative of f(x) is f'(x) = 2x + 9.  The integral is:

x³ / 3 + 9x² / 2 + 18x + C

Answers

Answer:

0.1, 0.18, 0.21, 0.222, 0.24

Explanation:

look at the first number:

between 0.1 and 0.18, 0.1 is smaller therfore it is the least

next to that would be 0.18

next, 0.21, 0.222, and 0.24 all has the same first number so take a look at the second number:

0.21 would be the third number since the second number is 1, which is the smaller number out of 3

the 4th number would be 0.222 because 0.22 is less than 0.24

lastly, the greatest or largest number would 0.24
