Answer:

Step-by-step explanation:

The formula for simple interest is

prt = I, where p is the initial investment, r is the interest rate in decimal form, t is the time it's invested for, and I is the interest earned. We multiply the p, the r, and the t together to get I. For us that looks like this:

(2.58)(.05)(4) = I and

I = .516 or 52 cents.

Answer:

$0.516≈ 0.52

Step-by-step explanation:

For simple interest:

=PRT/100

=2.58 * 5 * 4/100

= 51.6/100

= $0.516 = $0.52 ( when rounded off)

4500 meters. You find this by adding 1/3 and 2/5 which equals 11/15. This means that the remaining 4/15 is 1200 meters long. Divide 1200 by 4 in order to find the distance per 1/15 and you get 300. Multiply 300 with 15 to get the total distance of the race.

1) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum simple interest after 6 years are <u>R25,400</u> and <u>R5,400</u> respectively.

2) The accumulated amount after six years and the total interest that Trevor will receive if the interest rate is 4.5% per annum compound interest after 6 years are<u> R26,045.20</u> and <u>R6,045.20</u> respectively.

<h3>Data and Calculations:</h3><h3>Simple Interest:</h3>

Principal = R20,000

Investment period = 6 years

Interest rate = 4.5%

Simple interest for 6 years = R5,400 ($20,000 x 6 x 4.5%)

Principal + Interest = R25,400 (R20,000 + R5,400)

<h3>Compound Interest:</h3>

Principal = R20,000

Investment period = 6 years

Interest rate = 4.5%

N (# of periods) = 6 years

I/Y (Interest per year) = 4.5%

PV (Present Value) = R20,000

PMT (Periodic Payment) = R0

<u>Results</u>:

FV = R26,045.20

Total Interest = R6,045.2

PLEASE HELP ME!!!<br> Find the vertex of f(x)=x^2+2x+3 and show your work
belka [17]

Answer:

The vertex is the point (-1,2)

Step-by-step explanation:

we have

f(x)=x^{2}+2x+3

Convert into vertex form

Group terms that contain the same variable, and move the constant to the opposite side of the equation

f(x)-3=x^{2}+2x

Complete the square. Remember to balance the equation by adding the same constants to each side.

f(x)-3+1=x^{2}+2x+1

f(x)-2=x^{2}+2x+1

Rewrite as perfect squares

f(x)-2=(x+1)^{2}

f(x)=(x+1)^{2}+2 ----> equation in vertex form

The vertex is the point (-1,2)
