Step-by-step explanation:

Answer:
2.30/7.5
Step-by-step explanation:
4.30-2=2:30
2.5-10=7.5
Answer:
C
Step-by-step explanation:
V=4
/3πr3
3000=1 1/3*3.14*r*r*r
3000=4.18666667*r*r*r
716.560509=
Cube root the number
8.94851471456=r
TSA=4

TSA=4*3.14*8.94851471456*8.94851471456
TSA=1006.26
Since we used different numbers for pi and I rounded our answer will be different but the answer is C
When you multiply two complex numbers given in polar form, the argument of the product is the sum of the arguments of the factors. Meanwhile, the modulus of the product is the product of the moduli of the factors.
In this case, you'd have

and the modulus would simply be

. Since

we would expect the final product to fall in the first quadrant.
I assume you want the leading coefficient because there is only 1.
The leading coefficient is always in front of the term with the greatest exponent.
Leading coefficient = -1.
The degree of this function is 9. It is a ninth degree polynomial function. Why 9? It is a 9th degree polynomial because 9 is the greatest power.
