5 % 8,000 decreases to 400 by 5 %
Answer:
D
Step-by-step explanation:
Given that f(x) has domain { 2, 4, 7 }
Substitute the values from the domain into f(x) for the range
f(2) = 2² - 5 = 4 - 5 = - 1
f(4) = 4² - 5 = 16 - 5 = 11
f(7) = 7² - 5 = 49 - 5 = 44
Thus the range is { - 1, 11, 44 } → D
<span>First of all in order to find the exact value by using a half angle identity we will do
cos(5π divided by 12)
=cos (5π divided by 6) divided by 2
= ± Under root[(1+cos (5π divided by 6) divided by 2]
Now we will consider + sign because 5π divided by 12 is in quadrant. where cos>0
so the solution is [(1- Under root 3 divided by 2) divided by 2]
We will ignore the negative sign

Expenses: $6.00 + $4.50 + $2.50 = $13.00
income = balance + expenses
income = $3.52 + $13.00
income = $16.52
