Answer: the x intercept is -5 and the y intercept is 25.
Step-by-step explanation:
f(x) = -x^2 + 25
The x intercept is when y is zero and the y intercept is when x is zero.So input zero into the expression and solve for y.
-1(0)^2 + 25 = 25 so the y intercept is 25.
0=-x^2 +25
-25 -25
-25 = -x^2
x^2 = 25
x = -5 or 5
Answer:
1. 50 is 20% of 250
Step-by-step explanation:
In order to find any of these, use the equation.
Number/Out of = %
Then plug in the values
50/x = .20
Then solve by cross multiplying
50 = .20x
250 = x

Answer:
8000π mm^3/s ≈ 25,133 mm^3/s
Step-by-step explanation:
The rate of change of volume is found by differentiating the volume formula with respect to time.
V = 4/3πr^3
V' = 4πr^2·r'
For the given numbers, this is ...
V' = 4π(20 mm)^2·(5 mm/s) = 8000π mm^3/s ≈ 25,133 mm^3/s
_____
<em>Additional comment</em>
By comparing the derivative to the area formula for a sphere, you see that the rate of change of volume is the product of the area and the rate of change of radius. This sort of relationship will be seen for a number of different shapes.
Hello,
The answer is "16".
Reason:
Just divide 12 by 3/4:
12×4=48÷3=16
1×3=3÷3=1
16/1=16
Therefore they can make 16 pizza crusts!
If you need anymore help feel free to ask me!
Hope this helps!
