Answer:
The function f(x)=3x-10 has the greater value at x=8.
Step-by-step explanation:
In the table, x=8 corresponds to y=4.
In the function f(x)=3x-10 when x=8, y corresponds to f(8)=3(8)-10=24-10=14.
SInce 14>4 , the the function f(x)=3x-10 has a greater value at x=8 than the table does.
Answer:
the formula for the volume of a cone is:
1/3hπr²
1/3×12m×π×8m=100.48m³
It is B because 28 * 12 is 336 if you do 70 -28 is 42 so you do 42 *8 and that give you 336 as well
