Answer:
9. n=-15 , 10. f=6, sorry i can't help you more I am just tired and have to get some rest but i hope this helps
Step-by-step explanation:
9. Eight less than 1/3 a number n is -13
so -13 = 1/3n -8
then
-5 = 1/3n
multiply 3 to each side
-15 = n
10. a number f multiplied by -12.3 is -73.8
so -12.3f= -73.8
divide -12.3 on each side
so f=6
The polynomial function has exactly 6 roots is f(x) = 7x⁶ + 3x³ + 12. Then the correct option is D.
<h3>What is Algebra?</h3>
Algebra is the study of mathematical symbols and the rule involves manipulating these mathematical symbols.
According to the fundamental theorem of algebra.
The polynomial function has only exactly 6 roots.
The roots are the value of the variables in the polynomial at which the value of the polynomial is zero.
If the degree of the variable is n then the number of the roots will be n or less than n.
If the number of the roots are 6, then the degree of the variable will be 6 in the polynomial.
Then the polynomial function has exactly 6 roots is f(x) = 7x⁶ + 3x³ + 12.

20 golf balls can fit in the can.
<u>Step-by-step explanation:</u>
Given:
Height (h) = 10 Inches
Volume of 15.625 Pi inches cube.
To Find:
How many balls can be filled in that can.
Solution:
Diameter of the golf ball [as per standard value] = 1.68 in
Radius of the golf ball = 
Volume of the golf ball = 
=
=
Volume of the can = 
Now we have to divide the volume of the can by the volume of the golf ball, we will get =
balls
Thus we can conclude that approximately 20 balls can be filled in that can.
