Answer:

A

Step-by-step explanation:

We can find the surface area of the object by adding the surface areas of each part. We have many rectangle faces to count and two triangular faces. Each has a formula for the area. We will find the area of each and then add them all together.

Triangle - 0.5 *b*h

Rectangle - b*h

<u>Triangles</u>

There are two triangles on either side. The height is 1.5. The base is 1.8.

0.5(1.5)(1.8)=1.35 meters squared

Since there are two, we will add 1.35+1.35 in our final calculation.

<u>Rectangles</u>

We will start by calculating the largest rectangle on the side. It has height of 4 and a base of 2.5 (shown above left).

4(2.5)=10

Since there are two (one we can see and one we can't), we will add 10+10 in our final calculation.

Next we calculate the top and bottom. The height is 3 and the base is 2.5 on top. But the bottom sticks out more and adds 1.8 to its base.

Top - 3(2.5)=7.5

Bottom-3(2.5+1.8)=12.9

Finally, we will calculate the front side and back(not visible) as well as the slant up front. The back side has height 4 and base 3. The front side has base 3 and height 4-1.5=2.5. The slant has base 2.3 and height 3.

Back - 4(3)=12

Front- 3(2.5)=7.5

Slant - 3(2.3)=6.9

We add all together for the total surface area: 1.35+1.35+10+10+7.5+12.9+12+7.5+6.9=69.5 meters squared.

Which of the following relations describes a function?
PtichkaEL [24]

Howdy! My name is Christian and I’ll try and help you with this question!

Date: 9/29/20 Time:  9:08 am CST

Answer:

D.

{ (1, 3), (2, 3), (3, 3), (4, 3) }

Explanation:

This is because for each x value, the number on the left of the set, there is no other x values of the same number, ( 1, 2, 3, 4)

Hope this helps you with your question!

<em>Sincerely, </em>

<em> </em>

Find Horizontal and Vertical Asymptotes for y=(1)/((x+2)^3)
Usimov [2.4K]

Answer:

Vertical asymptote: x = -2

Horizontal asymptote: y = 0 or x axis.

Step-by-step explanation:

The rational function is given as:

y=\frac{1}{(x+2)^3}

Vertical asymptotes are those values of x for which the function is undefined or the graph moves towards infinity.

For a rational function, the vertical asymptotes can be determined by equating the denominator equal to zero and finding the values of x.

Here, the denominator is (x+2)^3

Setting the denominator equal to zero, we get

(x+2)^3=0\\(x+2)=0\\x=-2

Therefore, the vertical asymptote occur at x=-2.

Horizontal asymptotes are the horizontal lines when x tends towards infinity.

For a rational function, if the degree of numerator is less than that of the denominator, then the horizontal asymptote is given as y=0.

Here, there is no x term in the numerator. So, degree is 0. The degree of the denominator is 3. So, the degree of numerator is less than that of denominator.

Therefore, the horizontal asymptote is at y=0 or x axis.
