From what I see in the problem, the expression is
To solve, plug in a and k.
3*5^2=75
(3*5)^-1 = 1/15
5^-2 = 1/25
(x + y)^2 = (x^2 - 2xy + y^2)
First distribute the ^2 on the left side of the equation to each term inside the parenthesis:
x^2+ 2xy + y^2
Now pick one of the variables to solve for and isolate it:
(solving for x)
x^2 + 2xy + y^2 = x^2 - 2xy + y^2
x^2+ 2xy = x^2 - 2xy
2xy = -2xy
-x = x
x = 0
When you solve for y in the equation it will turn out to be 0 as well
It's 4:3 because it's divided by 6
Answer:all numbers work.
Step-by-step explanation:
Answer:
Volume of softball is 29 cubic inches.
Step-by-step explanation:
Here we are given that the diameter of a softball is 3.8 inches.
To find the volume of the softball, we must consider the volume of a sphere formula, which is given by:
We also know that radius is half of diameter.
Radius of softball is half of 3.8 which is 1.9 inches.
Plugging this value in the formula, we have
Volume = 28.73 cubic inches.
Rounding to the nearest whole number:
Volume of softball will be 29 cubic inches.
