The answer to the question is c.

Plug in x with 2. 8(2)+40= 16+40=56°

<3 & <4 are supplementary angles. Take the difference from 180. 180°-124°= 56°

A home builder wants to decorate the post at the bottom of a stairway. One way to do this is to glue a square-based pyramid to t

AysviL [449]

We have been given net of a pyramid. We are asked to find the total surface area of the pyramid.

The surface area of the pyramid will be area of base plus area of 4 triangular sides.

We have been given that base of pyramid is square, so area of base will be square of base side.

$\text{Area of base}=(\text{10 in})^2=100\text{ in}^2$

Let us find area of one triangular side.

$\text{Area of triangle}=\frac{1}{2}\times \text{Base}\times\text{Height}$

$\text{Area of triangle}=\frac{1}{2}\times \text{10 in}\times\text{6 in}$

$\text{Area of triangle}=\text{5 in}\times\text{6 in}$

$\text{Area of triangle}=30\text{ in}^2$

Now we will multiply area of one triangular face by 4 to find area of 4 triangular faces.

$\text{Area of 4 triangular faces}=4\times 30\text{ in}^2$

$\text{Area of 4 triangular faces}=120\text{ in}^2$

Total surface area of pyramid would be area of base plus area of 4 triangular faces.

$\text{Total surface area of pyramid}=100\text{ in}^2+120\text{ in}^2$

$\text{Total surface area of pyramid}=220\text{ in}^2$

Therefore, 220 square inches of copper sheet are needed to make one pyramid.

What is the vertex of the absolute value function defined by f(x)=|x+2|+4?

labwork [276]

There is no maximum value for the term inside the absolute value signs, but there is an absolute minimum, being zero when x=-2. And when x=-2, y=4, and that is your vertex:

(-2, 4)
