Answer:

2x^2+16x-66

Step-by-step explanation:

Use FOIL (First, Outside, Inside, Last)

(2x-6)(x+11)

F- 2x*x=2x^2

O-2x*11=22x

I--6*x=-6x

L--6*11=-66

2x^2+22x-6x-66

Combine like terms

2x^2+16x-66

Svet_ta [14]

Answer:

3620.57

Step-by-step explanation:

Given: Stacy hits the jackpot one day at the gumball machine and won 4 gumballs, radius of each gumball is 6 mm

To find: Total volume of all 4 gumballs

Solution:

Gumball is Spherical

Volume of Sphere = (4/3)πr³

r = Radius of Sphere

r = 6mm

Volume of 1 gumball = (4/3)π * 6³

= 288π mm³

Volume of 4 gumballs = 4 * 288π

= 1152π mm³

using π = 22/7

= 3,620.57 mm³

or using π = 3.14

= 3,617.28 mm³

Volume of 4 gumballs = 288π mm³ ≈ 3,620 mm³

What graph represents the function f(x)=3x-2/x-2

Yuri [45]

Well, i think that first you should add the function of 3x to 2/, so you get 46. Now, multiply 46 to -2 and you get 51. Finally add 3x, 51, and 46 together, and you'd get 711.4

The lead of a screw is the distance that the screw advances in a straight line when the screw is turned 1 complete turn. If a sc

pishuonlain [190]

Answer:

It would get <u>20</u> complete turns.

Step-by-step explanation:

Given:

The lead of a screw is the distance that the screw advances in a straight line when the screw is turned 1 complete turn. If a screw is 2 1/2 inches long and has a lead of 1/8 inch,

Now, to find complete turns.

Length of screw = $2\frac{1}{2}=\frac{5}{2}=2.5\ inch$

Lead of screw = $\frac{1}{8} =0.125\ inch.$

As, given the screw advances in a straight line when the screw is turned 1 complete turn.

Now, to get the number of complete turns it would divide length of screw by lead of screw:

$2.5\div 0.125\\\\=\frac{2.5}{0.125}\\\\=20.$

Therefore, it would get 20 complete turns.
