<span>The formula for the volume of a sphere is V=4/3πr^3. Find the radius of a sphere with each volume.
1. 10 in^3
Solve for r
r =~ 1.3365 inches</span>
To prove:
Solution:
Multiply first term by and second term by .
Using the identity:
Denominators are same, you can subtract the fractions.
Using the identity:
Using the identity:
------------ (1)
Using the identity:
------------ (2)
Equation (1) = Equation (2)
LHS = RHS
Hence proved.
The roots of this equation are x = -5.5 and x = -.5
We can find this by using the quadratic equation which is listed below.
Now in order to find the right numbers to put into this equation. we look back to the original problem. Our a value will always be the number attached to x^2 (in this case 4), the b value will be attached to x (24) and the c value will be attached to no variable (11). Now we can do the operations and solve.
-3 +/- 5/2
-3 + 5/2 = -0.5 and -3 - 5/2 = -5.5
Giving you those x values.

Answer:
2.4 hrs = 144 minutes.
0.4 x 60 = 24
60+60+24 = 144 minutes.
Step-by-step explanation:
Volume = 1 m x 1m x 0.30 = 0.30 m^3
rate = 125ml
125 / 1000
0.30 / 0.125 = 2.4 hours.
