Answer:
r = √(V/(πh))
Step-by-step explanation:
To solve for r, "undo" what has been done to r. The "undo" is generally in the reverse order. Here, we have ...
- r is squared
- the square is multiplied by πh
To undo these operations, we ...
V/(πh) = r² . . . . . . . . divide by πh
√(V/(πh)) = r . . . . . . take the square root
r = √(V/(πh))
Answer:
3 seconds
Step-by-step explanation:
When the ball hits the ground, the height will be 0. Therefore, you can substitute 0 in for the value of f(t), hence the equation will be:
0 = -16t^2 + 32t + 48
You can then factor out -16:
0 = t^2 - 2t - 3
Factor:
0 = (t-3)(t+1)
t = 3, -1
However -1 is an extraneous solution because time cannot be negative. Therefore, the answer is 3 seconds.
Answer:
1.) x=6
2.)n=13
Step-by-step explanation:
1.)
-4x-3=-6x+9
−4x=−6x+9+3
−4x+6x=12
2x=12
x=12/2
<u>Answer:</u> <u>x=6
</u>
<u></u>
2.)
41-2n=2+n
41=2+n+2n
41=2+3n
41−2=3n
39=3n
39/3=n
13=n
<u>Answer:</u> <u>n=13
</u>
