Answer:

there is no factorization of y^2 -2y +35 in real numbers

Step-by-step explanation:

Thomasina correctly determined two factors of 35 that differ by 2, but that is not what is needed here. For this problem, she needs two factors of 35 that have a <em>sum</em> of 2.* (There aren't any real-number factors that meet that condition.)

The factorization in complex numbers would be ...

= (y -1 -i√34)(y -1 +i√34)

_____

* Technically, she needs two factors of 35 with a sum of -2. Both factors would have to be negative.

. A cone with a radius of 5 cm and height of 8 cm is to be printed from a 3D printer. The medium that the printer will use to pr

Maurinko [17]

Answer:

The cone'll require about 37.5 cm of tubing

Step-by-step explanation:

To do this, we need to know that the volume of the medium will have to be the same volume of the cone that will be printed.

Then, the volume of the cone is:

V = π*r^2*h/3

V = 3.14 * 5^2*8 / 3 = 209.33 cm^3

We can assume that the tubing is a cylinder so:

V = π*r^2*h

The radius is 1 1/3, and this is:

1*3 + 1 = 4/3

Solving for h we have:

h= V/π*r^2

h = 209.33 / 3.14*(4/3)^2

h = 209.33 / 5.58

h = 37.5 cm

The slope of line AB, BC, CD and AD are 1, -1/6, 2, -4/6 respectively. Quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C

<h3>How to determine the slope</h3>

Formula for slope is given as;

Slope = $\frac{y2 -y1}{x2 -x1}$

A(-4 -1)

B(-1 2)

C(5 1)

D(1 -3)

a. Slope of line AB = $\frac{2- (-1)}{-1 (-4)}$ = $\frac{2+ 1}{-1 + 4}$ = $\frac{3}{3}$ = 1

b. Slope of line BC = $\frac{1-2}{5-(-1)}$ = $\frac{-1}{6}$

c. Slope of line CD = $\frac{-3 - 5}{1-5}$ = $\frac{-8}{-4}$ = 2

d. Slope of line AD = $\frac{-3 (-1)}{1 -(-4)}$ = $\frac{-4}{5}$

Quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C

Thus, the slope of line AB, BC, CD and AD are 1, -1/6, 2, -4/6 respectively.

and quadrilateral ABCD with the given vertices is not a parallelogram because neither pair of opposite sides is parallel. Option C

vivado [14]

Answer: 1620 in.^3

Step-by-step explanation: Basically, you have a prism that has a base of 180, and a height of 9 in. The volume of a rectangular prism is length*width*height, and 180 is the length*width, so to find the answer, you do 180*9, which is equal to 1620.
