What are the answer choices ? There is none.
Volume of sphere = 4/3 πr³
V = 4/3 * 3.14 * (10)³
V = 4.186 * 1000
V = 4186 in³
So, your final answer is 4186 in³
Hope this helps!
Answer:
Step-by-step explanation:
So we have the two functions:
And we want to find f(g(1)).
So, let's find g(1) first:
Substitute 1 for x:
Simplify:
Add:
So:
Now, substitute 2 for x in f(x):
Multiply:
Add:
So:
Answer:
Step-by-step explanation:
3(2 + 4x) = -7 x 2 Distribute the 3
6 + 12x = -14 Subtract 6 from both sides of the equation
12x = -20 Divide both sides by 12
x = Divide the top and the bottom of the fraction by 4
x =
<u>ANSWER </u>
<u>EXPLANATION</u>
We the have the equations,
Multiplying through by negative one gives,
Also
and
Dividing through by 2 gives
Making z the subject gives,
Now we substitute equation (3) into equation (1) and (2)
Equation (3) in to equation (1) gives,
This implies that;
We now put equation (3) in (2) to get,
This implies that
But
So,
Dividing through by negative 9 gives
and
Therefore
