= 7i / (3 - 11i)

= 7i (3+11i) / [ (3 - 11i) (3 + 11i) ]

= (21 i - 77) / (9 + 121) = choice (d), (-77 + 21i) / 130

Given:

Given triangle is an equilateral triangle

Side of given triangle = 10 unit

Angle S = 5x°

Find:

The value of variable x

Computation:

We know that each angle of an equilateral triangle is 60°

So,

Angle S = 60

By putting value of angle S

5x = 60

The value of variable x = 60 / 5

The value of variable x = 12

Find the simple interest earned
after 8 years in an account with a
principal of $5,000 and an annual
interest rate of 3%.

Answers

Answer:

SI = $1,200 ; A = $6,200

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3%/100 = 0.03 per year,

then, solving our equation

I = 5000 × 0.03 × 8 = 1200

I = $ 1,200.00

The simple interest accumulated

on a principal of $ 5,000.00

at a rate of 3% per year

for 8 years is $ 1,200.00.
