What are the domain and range of the inequality y < sqrt x+3+1
love history [14]

Given:

The inequality is:

y

To find:

The domain and range of the given inequality.

Solution:

We have,

y

The related equation is:

y=\sqrt{x+3}+1

This equation is defined if:

x+3\geq 0

x\geq -3

In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.

So, the domain of the given inequality is x>-3.

We know that,

\sqrt{x+3}\geq 0

\sqrt{x+3}+1\geq 0+1

y\geq 1

The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.

So, the domain of the given inequality is y>1.

Therefore, the correct option is A.

Find the surface area of this triangular prism. Be sure to include the correct unit in your answer.
makkiz [27]

Answer:

390ft^2\\

Step-by-step explanation:

Ok so we have 2 (congruent) triangles and 3 rectangles.

Your main approach to this problem should be to find the area of each of the faces and adding them up to get to your final answer. Your question makes a point of including the correct unit in your answer. Since this is surface area, the unit would be ft^2

Now let's start:

First, I am going to start with finding the area of the rectangles.

12\cdot11=132\\13\cdot11=143\\5\cdot11=55\\\\55+143+132=330

Alright, next lets move on to the triangles.

They are both the same, if you notice. So find one and double it.

12\cdot5=60\\\frac{60}{2}=30\\30\cdot2=60

now lets add em all

330+60

= 390 and thats your final answer, dont forget to include the unit, ft^2
