Answer:
20.48 is the radius of sphere
Step-by-step explanation:
V=(4
/3)πr3
Using the formula
r=(3V
/4π)⅓
Solving for "r"
r=(3V
4π)⅓=(3·36000
/4·π)⅓≈20.48352
Step-by-step explanation:
Divide 180 by 3 = 60
Divide 150 by 2 = 75
The faster vehicle is truck and its speed is 75 mph
-4x is the slope and -12 is the y-intercept
Let the variable for total cost be c and person be p
c = 5x + 5x
For this case suppose that we have a quadratic equation of the form:

The solution to the quadratic recuacion is given by:

Where,
The discriminant is:

When the discriminant is greater than zero, then the root is positive, and therefore, we have two positive real solutions.
Answer:
B. it has two real solutions
