How much to the nearest dollar should you deposit in a savings account at 2.5% annual simple interest in order to have a balance

of $20,000 after five years?

Answer:

The amount we have to deposit in a savings account x = $ 17777.78

Step-by-step explanation:

Amount = $ 20000

R = 2.5 %

Time = 5 years

Take principal amount = x

Simple interest earned in five years

S.I. = \frac{P R T}{100}

S.I. = \frac{P (2.5)(5)}{100}

S.I. = \frac{x}{8}   ------- (1)

We know hat total amount is given by

Total amount = principal amount + simple interest

A = x + S.I.

A = x + \frac{x}{8}

A = \frac{9x}{8}

Given that the total amount after 5 years is = $ 20000

\frac{9x}{8} = 20000

x = $ 17777.78

This is the amount we have to deposit in a savings account.

Suppose you want to solve the equation 2a + 2b= 2a, where a and b are nonzero real numbers. Describe the solution to this equati
Anna11 [10]
This equation has no solution where 'a' and 'b'
are both non-zero real numbers.

You said                                 2a + 2b = 2a

Subtract 2a from each side:         2b = 0

'b' must be zero.

And it doesn't matter what the value of 'a' is.
As long as b=0, 'a' can be any number.

Write the standard form of the line that passes through the given points. Include your work in your final answer. Type your answ
enot [183]

2x - 3y = - 13

the equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

First obtain the equation in slope-intercept form

y = mx + c ( m is the slope and c the y-intercept )

calculate m using the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (1, 5 ) and (x₂, y₂ ) = (- 2, 3 )

m = \frac{3-5}{-2-1} = \frac{-2}{-3}= \frac{2}{3}

y = \frac{2}{3} x + c ← partial equation

to find c substitute either of the 2 points into the partial equation

using (1, 5 ), then

5 = \frac{2}{3} + c ⇒ c = \frac{13}{3}

rearrange the equation into standard form

multiply through by 3

3y = 2x + 13 ( subtract 3y and 13 from both sides )

2x - 3y = - 13 ← in standard form

Solve for r in terms of s, t, and u. <br> t=u-s+r
Verdich [7]

Answer:

r = t - u - s

Step-by-step explanation:

To solve for r in terms of s, t, and u, means to have r on one side and have t, u, and s.

t = u - s + r

t - u = s + r

t - u - s = r
