B does not represent a function
Answer:
m∠2= 180-30=150
m∠3= 30
m∠4=30
m∠5=150
m∠6=150
m∠7=30
Step-by-step explanation:
since these are angles of parallel lines cut by a transversal the theorems of vertical, corresponding, supplementary, and complementary angles apply.
Answer:
1. x=±4
2. t=±9
3. r=±10
4. x=±12
5. s=±5
Step-by-step explanation:
1. x^2 = 16
Taking square root on both sides

x=±4
2. t^2=81
Taking square root on both sides

t=±9
3. r^2-100=0

r=±10
4. x²-144=0
x²=144
Taking square root on both sides

x=±12
5. 2s²=50

s=±5 ..
To find the volume of this sphere you use the equations 4/3 times pi times r^3
For this question it would look like this 4/3 * 3.14 * 8^3=v
The answer is v = 2144.66058
