Mathematics

Answer:

55.4 in³

Step-by-step explanation:

The formula for the volume of a pyramid can be found:

V = \frac{1}{3}Bh, where B = area of the base and h = height of the pyramid

Since the base is a triangle, we need to use the formula for the area of a triangle:

A = \frac{1}{2}bh = \frac{1}{2}(5.7)(6.2)=17.67in^{2}

Next, multiply the area of the base by the height of the pyramid:

17.67 x 9.4 = 166.098 ÷ 3 ≈ 55.4 in³

Consider the piecewise-defined function given by the graph. What are these values?
maksim [4K]

Answers:

f(-3) = -1

f(-1) = 2

f(3) = 5

======================================

Explanations:

Draw a vertical line through -3 on the x axis. Make sure this vertical line crosses the orange graph. Mark this point of intersection and then draw a horizontal line from this point to the y axis. You should find that it touches -1 on the y axis. Check out the attached image to see this process in action.

Those steps basically say that x = -3 leads to y = -1. Since y = f(x), this means f(-3) = -1

Through similar steps, you should find that f(-1) = 2 and f(3) = 5

Note that the open hole/circle does not count. So if you land on an open hole, just keep going until you hit a closed circle on the other piece of the graph.
