Answer: 15 inches
Step-by-step explanation:
Volume(V) = 40 cubic inches
Height (h) = 8 inches
1.) Volume of cone = (1/3) × base(B) × h
2.) 40 = (1/3) × base × 8
3.) 40 = (8/3) × base
4.) Multiply both sides by the reciprocal (3/8)
(40) × (3/8) = (8/3) × (3/8) × base
120/8 = base
15 = base
Therefore, base area of cone = 15 inches
The answer is A: a slope of 2/9
First you need to change find the y-intercept by converting the standard form equation to slope-intercept form. The goal is to isolate y:
x + 4y = 12
x + 4y - x = 12 - x
4y = 12 - x
4y / 4 = 12/4 - x
y = 3 - x
Change so that the slope is before the intercept:
y = -x + 3
Now we know that the y-intercept is 3.
Use the slope equation, which is y2 - y1/x2 - x1, is find the slope:
5 - 3/9 - 0 = 2/9
So, the slope is 2/9!
Answer:
See explanation.
Step-by-step explanation:
We need a point and a slope to have a point slope equation.
We need a slope and y-intercept to write in slope intercept form.
