PLEASE PLEASE HELP!!!!! 1. What is the domain of the function shown below?

<h3>Answer: Choice A</h3>

$-8 \le x < 3 \text{ and } 4 \le x < 8$

=======================================================

Explanation:

Place your pencil on the curve. Then draw a straight vertical line either up or down until you reach the x axis. If you were to start at the left endpoint, and work your way to the right, you'll eventually shade the interval $-8 \le x < 3 \text{ and } 4 \le x < 8$ along the x axis.

We have two separate intervals being shaded in. There's a small gap from 3 to 4 that isn't shaded in.

Refer to the diagram below.

Find the surface area of this prism. How to get the answer??

babymother [125]

To find the surface area of a prism (or any other geometric solid) we open the solid like a carton box and flatten it out to find all included geometric forms. To find the volume of aprism (it doesn't matter if it is rectangular or triangular) we multiply the area of the base, called the base area B, by the height h

Nikki is building a wall for her garden with bricks. each brick is 10 inches long. the bricks are laid end-to-end, and one inch

bearhunter [10]

Answer:

$11n-1=120$

Step-by-step explanation:

It is given that,

Length of each brick = 10 inches

Mortar between between each brick = 1 inch

For 2 bricks, we need mortar once.

For 3 bricks, we need mortar 2 times.

For 4 bricks, we need mortar 3 times.

Similarly,

For n bricks, we need mortar (n-1) times.

Total length of n bricks = 10n inches

Total length of (n-1) times mortar = 1(n-1) = n-1 inches

Total length of wall = 10n + (n-1) inches.

1 feet = 12 inches

10 feet = 120 inches

The equation to model the number of bricks,n, nikki needs in each layer to build a wall 10 feet long.

$10n+(n-1)=120$

$11n-1=120$

Therefore, the required equation is $11n-1=120$ .

Please solve it find the value of x

DENIUS [597]

Answer:

The measure of angle x is 25 degrees.

Step-by-step explanation:

Since triangle ABC is an isosceles triangle, the measure of angle BAC is equal to the measure of angle ACB. Angle ABC = 80 degrees, leaving 100 degrees to be divided equally for the measures of the other two angles. Now that you know that angle ACB = 50 degrees, you can calculate the value of angle ACD and determine that angle ACD = 130 degrees. Triangle ACD is also an isosceles triangle, and the two equal legs are AC and CD. Since angle ACD = 130 degrees, the other two angles have a total of 50 degrees. Splitting the 50 degrees equally between the two angles gives you 25 degrees as the value of angle CAD, which is labeled "x."
