The answer is x=20. Hope this helps.
Step-by-step explanation:
50% interest annually.
that means he gets 50% interest of the invested capital every year.
and that means he gets 50% of $70 in one year.
70 = 100%
1% = 100%/100 = 70/100 = $0.70
50% = 1%×50 = 0.7 × 50 = $35
he will earn $35 interest in one year.
as you noticed: 50% simply means 1/2 (as 100% stands for the whole).

The required domain of the inverse function is x ≤ 0. Hence option D is correct.
f(x) = -x^2
<h3>What are functions?</h3>
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is independent variable while Y is dependent variable.
Inverse of function f(x) = -x^2
y = -x^2
x = √-y
Now,
Inverse function of f(x) is √-x
Its domain is define as less than or equal to zero.
Thus, the required domain of the inverse function is x ≤ 0.

Answer:
c) $ 75.37
Step-by-step explanation:
The correct question is:
Martha earned a gross pay of $1,215.60 last week. Using the fact that Social Security tax is 6.2% of gross pay, determine the
amount of Social security tax deducted from Martha's gross pay
a $7.54
b. $65.37
c. $75.37
d. $75.40
<u>ANSWER: </u>
<em>Martha's gross pay </em>= $ 1,215.60
<em>Social Security Tax </em>= 6.2%
<em><u>Calculate Social Security tax:</u></em>
6.2% of 1,215.60
6.2/100 x 1,215.60 = $ 75.37
Therefore, the correct answer is option c: $ 75.37
