Answer:1
Which of the following functions has a line of symmetry of x = 2?
Step-by-step explanation:
1. C=2πr
We need to move r by itself on a side of the equation.
Divide both sides of the equation by 2π. This will cancel out the side with the r.
r=C/2π
2. A=1/2*b*h
Divide both sides by 1/2*h, isolating b
b=A/h
3.y=mx+b
Now we have to do reverse PEMDAS, we have to add/subtract before we can multiply or divide to simplify.
Subtract both sides by b
y-b=mx
Now divide both sides by m
x=
Remember we have to divide both terms y and -b by 2, so it goes on the bottom for both.
Answer:
x = 133
Step-by-step explanation:
Supplementary angles add to 180 degrees. Call the unknown angle x
47 +x = 180
Subtract 47 from each side
47-47+x =180-47
x = 133
Answer:
x = -7
Step-by-step explanation:
-2x - 10 = 4
-2x = 14 | Add 10 to both sides
x = -7 | Divide both sides by -2
Answer:
Step-by-step explanation:
Diameter:
from this information we can find the radius of the golf ball:
A golf ball is shaped like a sphere, and the formula for finding the volume of a sphere is:
where r is the radius and is a constant:
we substitute the values of pi and the radius to find the volume:
the closest to the volume of a golf ball:
