Answer:

A ≈ 47.759 cm²

Step-by-step explanation:

A = πr²

A = (3.14)(3.9)²

A = (3.14)(15.21)

A ≈ 47.759 cm²

Because the area of a circle equals pi times radius squared and the radius is 3.9 A= 47.78

Which correctly describes how the graph of the inequality 5x + 2y > 13 is shaded?
Leya [2.2K]

Answer:

We can't graph on this app but this is what I can give you.

Step-by-step explanation:

The 5+2 part automatically makes 7, obviously, meaning that x and y each would have to at least represent 2 for this equation to be true.

Describe the graph of the function f(x) = x3 − 15x2 68x − 96. Include the y-intercept, x-intercepts, and the shape of the graph
solong [7]
So this would be a cubic graph because the largest exponent is a 3.

The Y-intercepts can be found by making all the x's equal 0, so then that would end up being -96 (makes sense considering a cubic graph intercepts at the origin, and this graph moves it down 96 units.

The X-intercepts (the zeros) are a bit tricky. We know that there will likely be three zeros because the exponent is a three. The zeros for this graph are 3, 4, and 8

So in Summary:

This is a Cubic graph with X-intercepts at (3,0), (4,0) and (8,0) and with Y-intercept at (0,-96)
