3. Which point lies inside the circle with equation (x - 2)2 + (y + 3)2 = 4?
2 answers:
Answer:
C (2,-4)
Step-by-step explanation:
You could graph the circle and then graph the points and see...
Or you could them in and see which point makes the left hand less than 4?
So if you wanted to draw it is a circle with center (2,-3) and radius 2.
If you want to do it the other way:
Plug in time!
(2,-5)?
(2-2)^2+(-5+3)^2
0^2+(-2)^2
0+4=4 so not this one
(2,-4)?
(2-2)^2+(-4+3)^2
0+1
1<4 so this one (you can also see this in the drawing:

<u>Given</u>:
Given that the triangular prism with height 10 inches.
The side lengths of the base of the triangle are 12 inches, 13 inches and 5 inches.
We need to determine the surface area of the prism.
<u>Surface area of the prism:</u>
The surface area of the prism can be determined using the formula,
where b is the base and h is the height of the triangle.
s₁, s₂, s₃ are the side lengths of the triangle and
H is the height of the prism.
Substituting b = 12, h = 5, s₁ = 12, s₂ = 5, s₃ = 13 and H = 10 in the above formula, we get;
Thus, the surface area of the triangular prism is 360 square inches.
Hence, Option b is the correct answer.
