Albert deposits $2785 in an account that earns 3.9% interest compounded monthly. this function models the amount in the account
Step2247 [10]

The amount for the given data is found as,\rm a = 2825(1+\frac{3.9}{12} )^{12t}.The given expression is true.

<h3>What is the amount?</h3>

The complete repayment of money at the end of the period for which it was borrowed is referred to as the amount.

The given data in the problem is;

P is the annual payment=2827

r is the rate of interest = 3.9%

n is the time period=12

The formula for the amount is found as;

\rm a = p(1+\frac{r}{n} )^{nt}

Substitute the given value;

\rm a = 2825(1+\frac{3.9}{12} )^{12t}

Hence the given expression is true.

To learn more about the amount, refer to the link: brainly.com/question/12184047.

Answer:

B is the correct answer

Step-by-step explanation:

  1. Subtract area of triangle from total area: 30 - 14 = 16
  2. Since the figure is a square, all the sides are equal. Therefore, we need to find the square root of 16: √16 = 4
  3. All the sides of the square are 4 cm long

  1. To check, reverse application:
  2. 4 x 4 = 16
  3. 16 + 14 = 30

Work out the number of years of investment for each return.
Mamont248 [21]

Answer:

41 years approx

Step-by-step explanation:

Given data

P=  £3000

R=3%

Simple Interest= £3720

Time=???

We know that from the simple interest expression

SI= PRT/100

substitute

3720= 3000*3*T/100

Make T subject of the formula

T= 3720*100/3000*3

T= 372000/9000

T= 41.33

Hence the number of years is 41 years approx

Given the function g(x)=x^2+2x-5g(x)=x
dimaraw [331]

We have been given a function g(x)=x^2+2x-5. We are asked to find average rate of change of the function over the interval -6\leq x\leq 1.

We will use average rate of change formula to solve our given problem.

\text{Average rate of change}=\frac{f(b)-f(a)}{b-a}

For our given function b=1 and a=-6.

\text{Average rate of change}=\frac{g(1)-g(-6)}{1-(-6)}

g(1)=1^2+2(1)-5

g(1)=1+2-5

g(1)=-2

g(-6)=(-6)^2+2(-6)-5

g(-6)=36-12-5

g(-6)=19

\text{Average rate of change}=\frac{-2-19}{1+6}

\text{Average rate of change}=\frac{-21}{7}

\text{Average rate of change}=-3

Therefore, the average rate of change of the function is -3 over the interval -6\leq x\leq 1.
