Sharon borrowed $750 at 12% for one year. She paid a $20 processing fee. How much will she pay in interest?
Hunter-Best [27]

Answer:

$90

Step-by-step explanation:

The principal amount in the loan taken by Sharon is $750 . Note hat the $20 processing fee is a one time cost and is not included in the interest calculation.

Annual Rate of interest offered to Sharon is 12%

Time interval for the loan transaction is 1 year.

So the interest for 1 year is given by \[Principal * Rate * Year /100\]

\[750 * 12 * 1 /100\] = $90

So, Sharon will have to pay $90 as interest for the loan amount $750 borrowed for one year at the rate 12%.

If f (x) = -9x - 9 and g (x) = Vx - 9, what is (f ° g) (10)?
Temka [501]

Answer: (f \circ g) (10)= -18\ .

Step-by-step explanation:

Given: f (x) = -9x - 9 and g (x) = \sqrt{x - 9}

To find : (f o g) (10)

For this we first find (f o g) (x)= f(g(x))

=f(\sqrt{x-9})\\\\=-9(\sqrt{x-9})-9

Now,

(f \circ g) (10)=-9(\sqrt{10-9})-9\\\\=-9\sqrt{1}-9\\\\=-9-9=-18

Hence, the value of (f \circ g) (10)= -18\ .

ch4aika [34]

Answer:

-\dfrac{3}{5}

Step-by-step explanation:

1. Find the numerator:

\dfrac{1}{3}-\dfrac{5}{6}=\dfrac{1\cdot 2}{3\cdot 2}-\dfrac{5}{6}=\dfrac{2}{6}-\dfrac{5}{6}=\dfrac{2-5}{6}=-\dfrac{3}{6}=-\dfrac{1}{2}.

2. Simplify the fraction:

\dfrac{-\frac{1}{2}}{\frac{5}{6}}=-\dfrac{1}{2}\cdot \dfrac{6}{5}=-\dfrac{3}{5}.
