Answer:
89
Step-by-step explanation:

we evaluate when t=2

so it's 89 feet
Answer:

Step-by-step explanation:
So we have the system:

If we isolate the x-variable in the first equation:

Subtract 2y from both sides:

Divide both sides by -1:

Therefore, we would substitute the above into the second equation:

The answer is 2y+6
Further notes:
To solve for the system, distribute:

Simplify:

Subtract:

Divide:

Now, substitute this value back into the isolated equation:

Answer:
45 %
Step-by-step explanation:
V= 3.14r^2h
10/2= r
5^2= 25
(3.14)(25)(6)
V=471
