marishachu [46]
Well lets work it out.
Diameter = 2 * Radius
Diameter * 1/2 = 1/2 * 2 * Radius
That would mean that the Radius would also be halved.
(1/2 * Radius)^2 * pi * height = volume, and 0.5^2 = 1/4, so its volume is reduced by a fourth

Anyone know the answer to this one ?
lys-0071 [83]

Answer:  B) y = 2 · 3ˣ

<u>Step-by-step explanation:</u>

We can see that (2, 18) is a point on the graph.

Plug it into the equations to see which one make a true statement.

        A) y = 1 · 3ˣ

            18 = 1 · 3²

            18 = 1 · 9

             18 ≠ 9

       B) y = 2 · 3ˣ

          18 = 2 · 3²

           18 = 2 · 9

           18 = 18             This works!

       C) y = 3 · 2ˣ

          18 = 3 · 2²

           18 = 3 · 4

           18 ≠ 12

       D) y = 4 · 3ˣ

          18 = 4 · 3²

           18 = 4 · 9

           18 ≠ 36

Given the trinomial, what is the value of the coefficient 'B' in the factored form?. . 2x^2 + 14xy - 36y^2 = 2(x + By)(x - 2y).
soldi70 [24.7K]
The value of the coefficient B is 9.

2(x+By)(x-2y)
=2(x^2 -2xy +Bxy -2By^2)
=2x^2 -4xy + 2Bxy - 4By^2

The original form is 2x^2 + 14xy - 36y^2

-36y^2 = -4By^2
B= 9
-4xy +2Bxy= 14xy
xy(-4 +2B)= 14xy
-4 + 2B = 14
2B = 18
B=9
