Assuming the question marks are minus signs
to find max, take derivitive and test 0's and endpoints
take derivitive
f'(x)=18x²-18x-108
it equal 0 at x=-2 and 3
if we make a sign chart to find the change of signs
the sign changes from (+) to (-) at x=-2 and from (-) to (+) at x=3
so a reletive max at x=-2 and a reletive min at x=3
test entpoints
f(-3)=83
f(-2)=134
f(3)=-241
f(4)=-190
the min is at x=3 and max is at x=-2
Answer:
She spent $26.50
Step-by-step explanation:
subtract $18.50 from $45.00
Answer:
7/165
Step-by-step explanation:
We take number after the decimal point 042
then we subtract the non repeating.In this case is 0 so we not subtract anything
This will be the numerator 42
For each repeating decimal we write a 9 (in this case 2 nines)
For each non repeating decimal we write a zero
Denominator is 990
42/990 = 7/165
7:165 = 0.0424242
I think this is what you do. Hope it helps!
Answer:
Renata has a home loan for $150,000 at 7.5% interest for 30 years and her payment is $987.00 per month.
I have solved this using excel sheet that is attached here.
p = $150000
r = 7.5%
t = 
EMI = $987
You can see the excel sheet, after first month principle is $ 149,950.50 and after second month it is $149,900.69 .
