I’m not sure if this is what you meant but since you know the surface area of a sphere is 4 Pi r ². You can work backwards and do the opposite (ex: subtraction for addition)
This can help you get the radius as the answer. Since the volume of a sphere is 4/3 Pi r ², just plug in the radius.
Answer:
C. Linear
Step-by-step explanation:
both the slope and y-intercept is positive and if you make the graph their linear
The range is the difference between the largest number and the smallest number. Given our biggest number is 90, and our smallest number is 1, we can find the range.
Subtract the smallest number from the biggest number to find the range.
90 - 1 = 89.
89 is your range.
I hope this helps!
Complete Question is;
Which values of a and b make the following equation true (5x^7 • y²) * (-4x⁴ • y^5) = -20x^a • y^b
Answer:
Option A - a = 11 and b = 7
Step-by-step explanation:
We are given the equation as;
(5x^7 • y²) * (-4x⁴ • y^5) = -20x^a • y^b
In algebra, we know that, zⁿ × z² = z^(n + 2).
Thus, collecting like terms in powers on left hand side, we have;
-20(x^(7 + 4)) × (y^(2 + 5)) = -20x^a • y^b
-20(x^(11))•(y^(7)) = -20x^a • y^b
Comparing the left and right hand side, we have;
a = 11 and b = 7
