which answer choice explains the pattern for how to find the slope using an equation in standard form?

Question is using standard formula ax+by=c to find the slope by converting into slope intercept form y=mx+b

so we also need to convert ax+by=c into y=mx+b as shown below:

ax+by=c

ax+by-ax=c-ax

by=-ax+c

divide both sides by

y=-\frac{a}{b}x+\frac{c}{b}

Now compare it with y=mx+b, we get

m=-\frac{a}{b}

So using values of a and b, we can find the slope


compare given equation -5x+2y=15 with ax+by=c, we get:

a=-5, b=2

Now plug both into above formula

m=-\frac{a}{b}

m=-\frac{-5}{2}

m=\frac{5}{2}


Now matching these details with given choices we find that THIRD choice is the final answer.

The angle of elevation from the end of the shadow to the top of the man's head will be 34.077°.

<h3>What is a right-angle triangle?</h3>

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function. The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

A man who is 5feet 9inches tall casts a shadow of 8feet 6inches.

Assuming that the man is perpendicular to the ground.

5 ft 9 in = 69 in

8 ft 6 in = 102 in

Then the angle of elevation from the end of the shadow to the top of the man's head will be

tan θ = 69/102

θ = tan ⁻¹ (0.676)

θ = 34.077°.

3694.51 is the answer because the formula you have to use is V=pi r^2h.
V=pi14^2*6 
V=pi*196*6
V=pi*1176
V=3694.51
