Answer:

Simple Interest = $ 281.20

Step-by-step explanation:

Principal = $4000

Rate = 9.5%

       = 0.095

Time = 270 days

Changing the time into years :

1 year = 365 days

\implies \text{270 days = }\frac{270}{365}\thinspace{ years}

⇒ 270 days = 0.74 years

Now, Simple Interest = Principal × Rate × Time

⇒ Simple Interest = 4000 × 0.095 × 0.74

⇒ Simple Interest = $ 281.20

we know that

The simple interest formula is equal to

I=P*r*t

where

I is the simple interest

P is the principal ( the amount borrowed or deposited)

r is the interest rate

t is the time

in this problem we have

P=\$4,000\\ r=9.5\% = 0.095\\t=\frac{270}{365}

Substitute the values in the formula above

I=4,000*0.095*\frac{270}{365}

I=\$281.10

therefore

<u>the answer is</u>

The amount of interest earned is equal to \$281.10

Write the exponential function that passes through the points (3, 10) and (5, 40)
tigry1 [53]

Answer:

  y = (5/4)2^x

Step-by-step explanation:

The function value increases by a factor of 40/10 = 4 when x increases by 2. The function can be written as ...

  y = (reference value)·(growth factor)^((x -reference)/(change in x for growth factor))

  y = 10·4^((x-3)/2) . . . . . . using point (3, 10) as a reference

This can be simplified to ...

  y = 10·2^(x -3) = 10/8·2^x

  y = (5/4)2^x
