We are given degree of the polynomial function = 3.
Because degree is 3, there should be three x-intercepts of the given graph of the polynomial.
We also given roots of the equation f(x)=0 are −2 , 0, and 3.
Therefore, x intercepts should be at:
(0,0), (-2,0) and (3,0).
<h3>In the given options third option shows x-intercepts at 0, -2 and 3.</h3><h3>Therefore, correct option is 3rd option.</h3>
√180 x 2√30
√36 x 5 x 2√30
6√5 x 2√30
12√5 x √30
12√5 x 30
12√150
12√25 x 6
12 x 5√6
60√6

The answer is Option A.
Scale Factors
If the Scale Factor IS 1, the polygon stays the SAME.
(If an equilateral triangle has a side length of 8 and the scale factor is 1, the sides will stay at 8)
If the Scale Factor is MORE THAN 1, the polygon's sides INCREASE depending on what the scale factor is.
(If a square has a side length of 3 and the scale factor is 4, the sides will increase to 12)
If the Scale Factor is LESS THAN 1, the polygon's sides DECREASE depending on what the scale factor is.
(If a square has a side length of 5 and the scale factor is 1/2, the side lengths will decrease down to 0.5)
Therefore each side length of the new triangle is 4 times shorter than the original (Option A)
Answer:
C 44.59
Step-by-step explanation:
The first two shirts are full price
2*49.96 = 99.92
The third shirt is 50% off. That means it is 50% of the original price
.5*49.96 = 24.98
The total cost before tax is
99.92+24.98 =124.90
tax = cost * tax rate
tax = 124.90*.071
tax=8.87
Add this to the cost
final cost = 124.90+8.87
=133.77
We want to find the mean cost (average cost)
Take the total cost and divide by the number of shirts
133.77/3 =44.59
