Plug in -6 for a and -5 for b
3(-6)^2 - 4(-5)
3(36)+20
108+20
=120
The answer is 6. I know that because I solved the question and I got 6 I'm positive its 6. Hope this helps.
Answer:
9 seconds
Step-by-step explanation:
3 feet per second divided by 21 feet which is 9
<span>Two lines are parallel if their slope is the same.
You want to write 8x + 4y = 5 in the form y = mx + b, where m represents the slope and b is the y-intercept.
We need to isolate y in the given equation. The number next to x is the slope.
8x + 4y = 5
4y = -8x + 5
y = (-8x +5)/4
y = -2x + 5/4
The slope of the line we want is -2.
Two lines are perpendicular if the slope of the first line times the
slope of the second line produces a product of negative one.
Since our slope is -2, we know that -2 times 1/2 yields -1.
The slope of the line perpendicular is 1/2.

The volume of a cylinder is given by
where is the base area, and is the height.
We are already given the height, which is 10.
We can deduce the base area since we are given a diameter: the radius is half the diameter, so it's 8, and the area of a circle is given by
So, the volume is
