Use formula A=P(1+RT) to calculate the maturity value of the simple interest loan round to two decimal places.
kirill [66]

Answer:

$20,160

Step-by-step explanation:

They don't have a <em>year </em>to pay it back. They have <em>four </em>months so you just use that as time.

Write the equation

A = 15,000 x (1 + 0.086 x 4)

( ) first.

0.086 x 4 = 0.344

rewrite.

A = 15,000 x (1 + 0.344)

( ) again.

1 + 0.344 = 1.344

rewrite

15,000 x 1.344 = 20,160

Hope this helped! Please mark as brainliest! thanks!

If mc008-1.jpg, what is f(5.9)?
yulyashka [42]
The answer:

the full question is if f(x) = 3 [ x - 2 ] , what is f(5.9)?

9
10
11
<span>12

</span>first, [x - 2 ] is called the integer part of x-2, 
generally, to compute f(c) where c is a real number, it is sufficient to substitute the value of x by c.
so <span>f(5.9) = 3 [ 5.9 - 2 ] =  3 [ 3.9 ]

 as we know that </span>[ 3.9 ]=3
<span>
therefore
</span>3 [ 3.9 ]<span>= 3x3 =9

the answer is 9</span>
