Robert has a reccuring deposit account in a bank. he deposits $1500 per month for 4 years. if he gets $ 1,01,250 at the time of maturity, find
• the intrest paid by the bank,
• the rate of intrest.

1)$ 65250

2)

Step-by-step explanation:

Amount Deposited in 24 months = $1500 × 24 = $ 36000

Maurity amount = $ 1,01,250

1) So, intrest paid by the bank= $1,01,250 - $65,250

2)

Sorry, I tried to do this part but I got it wrong. please forgive me, may some genious save you.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
