The radius of the cylinder is 17 inches.
Step-by-step explanation:
Given,
Volume of cylinder = V = 289π in cubed
Height of cylinder = h = 1 in
Radius of cylinder = r
We know that;
Volume of cylinder = πr²h
Putting values;
Dividing both sides by π (pi)
Taking square root on both sides
The radius of the cylinder is 17 inches.

Answer:
b = 43
Step-by-step explanation:
So let's plug things in first:
y= 2x - 20 and y= -5x +b which can become →
2x - 20 = -5x + b (now you said that x=9 so let's plug that in)
2(9) -20 = -5(9) + b (now try solving that)
18 -20 = -45 + b → -2 = -45 + b ( so then add 45 to both sides)
43 = b ( and there's your answer )
Answer:
Converse is not true
Step-by-step explanation:
If x = 3, then x² = 9
But the converse is not true
Because if x² = 9, then x can be 3 or -3
Ballance method is just a fance method of helping you remember to DO THE SAME THING TO BOTH SIDES OF AN EQUATION to keep it ballanced
-10=2(-3x+1)
divide BOTH SIDES by 2 to get rid of that 2 in front
-5=-3x+1
minus BOTH SIDES 1
-6=-3x
divide BOTH SIDES by -3
2=x
-x-7=-12
add7 BOTH SIDES
-x+7-7=-12+7
-x+0=-5
-x=-5
multiplY BOTH SIDES -1
x=5
