Answer:

1. 16π m^2

2. 8π m^2

Step-by-step explanation:

We can think of this as a circle. The goat can at most be 4m away from the center. This can be visualized as a circle with 4m radius. The area for that is πr^2, or 4^2π, which is 16π meters squared.

Now, the goat has a semicircle of land because half of the circle area she once had is taken up by the side of the garage. 1/2 of 16π is 8π meters squared.

Good Luck!

The greater of two consecutive integers is 20 more than twice the smaller. find the integers.
Kipish [7]

Let x represent the smaller. Then x+1 is the greater of the two.

... 0 = x + 19 . . . . . subtract x+1

... x = -19

Your two integers are -19 and -18.

Each course at a community college is worth 1 or 2 credits. A group of students is taking a total of 16 courses that are worth a
Anuta_ua [19.1K]

Answer:

They  are taking 12 2 credit courses

The are taking 4  1 credit courses

Step-by-step explanation:

x = 1 credit courses

y = 2 credit courses

The number of courses is 16

x+y = 16

The number of credits is 28 so multiply the course by the number of credits

1x+2y=28

Subtract the first equation from the second equation

x+2y =28

-x-y=-16

-----------------

y = 12

They  are taking 12 2 credit courses

We still need to find the 1 credit courses

x+y = 16

x+12= 16

Subtract 12 from each side

x-12-12 = 16-12

x =4

The are taking 4  1 credit courses

Factor completely<br> -2x^4+6x^3+8x^2
vlada-n [284]

Answer:

-2x²(x + 1)(x - 4)

Step-by-step explanation:

Hello!

Factor:

  • -2x^4 + 6x^3 + 8x^2
  • -2x^2(x^2 - 3x - 4)        Take out GCF

Think: What numbers add up to -3 and multiply to -4?

Answer: -4 and 1

Continue:

  • -2x^2(x^2 - 3x - 4)
  • -2x^2(x^2 - 4x + x - 4)
  • -2x^2(x(x - 4) + 1(x - 4))       Factor by Grouping
  • -2x^2(x + 1)(x - 4)

The complete factored form is -2x²(x + 1)(x - 4)
