Answer:

7. 4910.4

8. 3.6

Step-by-step explanation:

To find the volume of this prism, you first need to find the area of the triangular base. Since it is an equilateral triangle, the formula for its area is simply \dfrac{\sqrt{3}}{4}a^2, which in this case is \dfrac{\sqrt{3}}{4}\cdot 18^2\approx 140.3. Multiplying this by the height of 35, you get about 4910.4 cubic yards. For the cylinder, the formula for the volume is V=\pi r^2 h. Plugging in your known values, you get:

282.7=\pi \cdot 5^2 \cdot h

h\approx 3.6 inches

Hope this helps!

The length of the garden is 11 yards.The width of the garden is 8 yards. Select all of the expressions that chole could use to f
Sati [7]

Answer:

The length of the fence is 38 yards

These are the expressions

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, a rectangle.

The length of the fence is the perimeter of the garden which is the expression that Chole could use

1. Perimeter = 2l+ 2w

2. Perimeter = 2(l+w)

Given data

Length = 11 yards

Width = 8 yards

Perimeter = 2(11)+ 2(8)

Perimeter = 22+16

Perimeter = 38 yards

Create polynomial functions using the given information:
ycow [4]

It's pretty much simple. Since we can factor a polynomial by its zeros, lets write one of degree nine :

X(X-1)(X-2)(X-3)(X-4)(X-5)(X+1)(X+2)(X+3)= X^9-9X^8+6X^7+126X^6-231X^5-441X^4+944X^3+324X^2-720X

This polynomial is of degree 9 and has exactly 5 strictly positive zeros : 1, 2, 3, 4, 5

And it has 3 negative zeros : - 1, -1, - 3

And it has 0 as a zero too.

There is also this one :

(X-1)(X-2)(X-3)(X-4)(X²+1)(X+1)(X+2)(X+3) = X^9-4X^8-13X^7+52X^6+35X^5-140X^4+13X^3-52X^2-36X+144

It has 4 positive zeros : 1, 2, 3, 4.

It has complex zeros : i and - i

3 negative zeros : - 1, - 2 , - 3

Good Luck
