Solve this equation with steps so I understand -16x^3+4x=0

1 answer:

5 0

<span>-16x^3+4x=0
-4x(4x^2 - 1) = 0
-4x(2x+1)(2x - 1) = 0 (factor using a^2 - b^2 = (a+b)(a-b))

-4x = 0; x =0
2x +1 = 0;x = -1/2
2x - 1 =0; x = 1/2

answer: x = 0, x = 1/2 and x = -1/2</span>

Find the domain and range of the exponential function h(x) = 125x.

Yanka [14]

H would decrease either way because h is a variable for a certain number. that number would usually be divided from both sides. you would be eliminating x from the equation. 125x/h. by dividing you are creating a smaller number. by dividing you are decreasing. you're welcome. :)

[PROBABILITY] THERE ARE FOUR PEOPLE IN A ROOM THAT HAVEN'T MET BEFORE. THEY ARE TOLD TO SHAKE HANDS, EXACTLY ONCE, OF EVERY OTHE

Ivahew [28]

Answer:

Step-by-step explanation:

Let the 4 people be A, B, C and D. If each of them shakes hands with another person exactly one time then that means

A shakes with B, C and D. So 3 handshakes

B already shakes with A. So B shakes with C and D. 2 handshakes

C already shakes with A and B. So C shakes with D only. 1 handshake.

D already shake hand with all above.

Total handshakes: 3 + 2 + 1 = 6
