Graph a line with a slope of 3/4 that contains the point (2,-3).

arsen [322]

Answer:

Step-by-step explanation:

First, plot the point (2, -3) on the graph. Then, use the slope to pick another point. The slope is rise over run. For your slope, the line will go 3 places up and then 4 places to the right. Using a straight-edge, follow the points and you will get the graph of the line.

Which figure best demonstrates the setup for the box method of finding the area of a triangle

Ivanshal [37]

Hi there! The third option shows us the best setup.

We can find the area of a triangle with the standard formula area = 1/2 * base * height.

To be able to fill in this formula, we need to have a base and a height. We can't easily find a triangle with given base and height, so we must look for another option.

We can also take the area of a square (length × width) and then divide the answer by 2. This is possible when we take the third setup. Hence the third answer is correct.

Find the following measure for this figure.

ss7ja [257]

Answer: last option (5π√146 units²)

Step-by-step explanation:

To solve the exercise you must apply the formula for calculate the lateral area of a cone, which is shown below:

$LA=r*L*\pi$

where r is the radius but L is the slant height.

As you can see in the figure attached:

$r=5$

But you need to find the slant height with the Pythagorean Theorem (L would be the hypotenuse):

$L=\sqrt{11^2+5^2}=\sqrt{146}$

Substitute into the formula, then:

$LA=(5)(\sqrt{146})\pi=5\pi\ \sqrt{146$ units²
