Answer:
hope this will help you ( ◜‿◝ )♡
Step-by-step explanation:
lateral surface area of the solid=ph
=(a+b+c)*h
=(5+4+3)*15
=12*15
=180cm²
The curves
and
intersect at approximately
. The area is then
I would say. C
Since 100 factor is 10b. And -144 is 12a^2
hope this helps and you get it right
Answer:
x = -1
Step-by-step explanation:
With the axis of symmetry, think of it as where you would slice this line in half, and both sides would look identical to each other. Since this is a quadratic function, this would be at where the vertex is.
The vertex is the part of the line where it "turns" around and starts going the other way. So vertex of this line is at (-1, 3).
Therefore, the axis of symmetry is at x = -1. This is since the function is pointing either up/down, and any value that is x = _ is a vertical line.
