1) Since the larger number is a negative, you’re going to get a negative solution for number one. An easy way to do the math is to ignore the negative sign in (-116) For a moment. And subtract 56 from it.
116 - 56 = 60. Don’t forget to place the negative sign we pushed to this side before the solution. The answer is -60.
2) We do the same thing we did in number one, but with new numbers. The answer in total is -178.
3. As stated, we do the same thing we did in number one. Just because there’s a decimal doesn’t change much. And your answer would be -1.1
The answer is 16 pi - 16. The area of each triangle is 8, so both triangles are 16. The area of the circle is pi times the radius squared, 16 pi.
We know that the volume of a sphere of radius r is given by

Now, we have been given the initial volume was 4,188.79 cubic centimeters. Let us find the radius at this time.
Substituting the value of volume in the above equation, we get

Now, the final volume is given by 14,137.167 cubic centimeters. Thus, we have

Now, let us find the surface areas for these two radii.
For 
Surface area is given by

Similarly, for

Therefore, the increase in the surface area is given by

Hence, the average rate at which the surface area is changing is given by

Therefore, the average rate at which the surface area is changing is given by 130.8 square centimeters per second.
Answer:
50y^4x/49
Step-by-step explanation:
y^3/98
((100* y^3/98 * x) * y
2.1 y^3 * y^1=y^(3+1)=y^4
