Answer:
A)No; any two cross sections of a cylinder that lie on planes parallel to the bases of the cylinder are congruent.
Step-by-step explanation: I had to answer it in class and got it right
x+4y=15 2x-y=-15
We have to make x neg.
-2(x) + 4y (-2)= -2(15)
-2x-8y=-30
2x-y=-15
-9y= -45
Solve for y
Y=-45/-9
Y = 5
Substitute your y answer into one original equation to find x .
x+4y=15
X+4(5)=15
X+20=15
X=15-20
X= -5
Answer is (-5,5)
Answer:
R = 
Step-by-step explanation:
I = 
( multiply both sides by 100 to clear the fraction )
100I = PRT ( isolate R by dividing both sides by PT )
= R
Answer:
√19 or 4.36 to the nearest hundredth
Step-by-step explanation:
10^2 = 9^2 + x^2
x^2 = 10^2 - 9^2
x^2 = (10-9)(10+9) = 19
x = √19.
