Answer:
for what? do you need a question answered?
It is 9 because you have a 30,60,90 triangle, and then you can use pythagorean theorem.
The path is in the shape of a parabola, the horizontal length is 24, so the middle point is at x=12, the symmetry line is x=12, the highest point (the vertex) is at (12,6)
the equation in vertex form is y=a(x-12)²+6
next, find a by using either one of the two points, the starting point (0,0) or the end point (0,24). obviously (0,0) is easier to calculate:
0=a(0-12)² +6
a=-1/24
so the quadratic equation is y=-
Answer:
range = maximum value - minimum value
Step-by-step explanation:
so here..the maximum value is 20 and the minimum value is 7
20-7 is 13=range
