(g-f)(3)=g(3)-f(3)=(6(3))-(4-3²)=(18)-(4-9)=18-(-5)=18+5=23

Answer:

First one: yes

Second one: yes

Third one: no

Step-by-step explanation:

To find the midpoint of a line segment, you take the x and y coordinates of the 2 points, add each of them up, and divide each of them by 2.

First one: x = (1+3)/2 = 2, y = (2+4)/2 = 3, so it's correct.

Second one: x = (-1+3)/2 = 1, y = (1+-1)/2 = 0, so it's correct.

Third one: x = (-3+-1)/2 = -2, y = (0+5)/2 ≠ 2, so it's not correct.

I really hope this helped.

Answer:

68.8 sq. inches.

Step-by-step explanation:

The triangular surfaces have sides 2 in by 3 in by 4 in.

So, half perimeter, s = \frac{2 + 3 + 4}{2} = 4.5

So, the area of the triangular face is \sqrt{s(s - 4)(s - 2)(s - 3)} = \sqrt{4.5 \times 0.5 \times 2.5 \times 1.5} = 2.9 sq. inches.

Now, the total surface area of the right triangular prism will be (2.9 × 2) + 7(2 + 3 + 4) = 68.8 sq. inches. (Answer)
