The question is a scientific inquiry. The explanation does not fit any of the four.
6-4 because the equation for slope is m=y2-y1/x2-x1
Answer:
1st blank: 160(2) - 16(2)²
2nd blank: 256
3rd blank: 5
4th blank: 400
5th blank: 10
Step-by-step explanation:
h(x) = -16x² + 160x
To find h(2) just replace x = 2 into the equation
h(2) = 160(2) - 16(2)² = 256 in
The maximum height coincides with the vertex of the parabola.
x-coordinate of the vertex: -b/(2a) = -160/[2*(-16)] = 5
y-coordinate of the vertex: -16(5)² + 160(5) = 400
To hit the ground means h(x) = 0
-16x² + 160x = 0
16x(-x + 10) = 0
x = 0
or
-x + 10 = 0
x = 10
Answer:
C. 10 sq. units
Step-by-step explanation:
Area of a pentagon = 1/2 * apothem * perimeter
1/2*(1.62)(2.36*5)=0.81*11.8=9.558
Therefore, about 10 sq. units, or option C.
I hope this helped and have a good rest of your day!
Answer:
4. -1/2 and 2
5. N and R
Step-by-step explanation:
Well if you want me too do 5 I’ll do 4 too.
So for #4 it’s actually pretty simple we just have to seperate y that’s it.
So first we have to get y by itself by subtracting 3x to the other side so the equation looks like this now
.
Now we have to take away the 6 and to do that we divide it to all the numbers and variables. Which gets us
.
So m and b are -1/2 and 2.
So we have to graph y = -1/2x + 2 so look at the image below.
So looking at the image we can see it passes through the points N and R.
