Answer:
150 in^2
Step-by-step explanation:
Each of the 6 identical faces is a triangle with a base of 5 in and a height of 10 in. The area of a triangle is given by the formula ...
A = 1/2·bh
For the given values, the area of one face is ...
A = (1/2)(5 in)(10 in) = 25 in^2
The figure has 6 identical faces of this area, so the total surface area is ...
A = 6×(25 in^2) = 150 in^2
Answer:
y = 2x - 4
Step-by-step explanation:
We'll write our equation in y = mx + b form, with m being the slope and b being the y-intercept. We already know our slope, so we can replace m with 2 like this: y = 2x + b. But we don't know what b is. We can use the point (3, 2) to figure out b's value, since it has an x-value (3) and a y-value (2):
2 = 2(3) + b
2 = 6 + b
-4 = b
So we have y = 2x + (-4), or y = 2x - 4.
Hopefully that was helpful! If you have more questions, let me know.
