Simplify (5^x+2-5^x)/5^x×4
murzikaleks [220]

Answer:

6

Step-by-step explanation:

The given expression is,

\frac{5^{x+2}-5^x }{5^x\times4}

Now, we know that,

a^{m+n} = a^m . a^n

Then,

5^{x+2}=5^x . 5^2

So,

\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5^x.5^2-5^x}{5^x\times4}

Now, taking 5^{x} common from the numerator of the given expression, then

\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5^x(5^2-1)}{5^x\times4}

\implies\frac{5^{x+2}-5^x }{5^x\times4}=\frac{5^2-1}{4}

\implies\frac{5^{x+2}-5^x}{5^x\times4}=\frac{5\times5-1}{4}=\frac{25-1}{4}

\implies\frac{5^{x+2}-5^x}{5^x\times4}=\frac{24}{4}=6

So, the simplified form of the given expression gives the result 6.

Joe is taking out a five year loan with a 7% interest rate compounded quarterly to buy a $4000 car. What will he have paid in to
Sergio [31]

Answer:

$5659.11

Step-by-step explanation:

We are given;

  • Time of loan maturity is 5 years
  • Rate of compound interest is 7% compounded quarterly
  • Principal amount of the car is $4000

We are required to determine the total amount he paid at the end of 5 years..

The concept being tested is compound interest;

We are going to use the compound interest formula;

Amount = P(1+r/100)^n

Where P is the the principal amount

r is the rate of interest

n is the interest periods

In this case;

n = (5 × 4) = 20

r = 7 ÷ 4 = 1.75 ( as the money was compounded quarterly)

Thus;

Amount =$ 4000 ( 1 + 1.75)^20

            = $4000 (1.0175)^20

            = $5659.11

Therefore, the money that Joe will have paid at the end of 5 years is $5659.11
