Answer:
b=84
Step-by-step explanation:
from your equation, subtract 3969 from each side
you are left with b^2=7056
sqrt b^2 = sqrt 7056
b=84
Answer:
18
Step-by-step explanation:
bc 8 digits in the ones place, and less than 21 greater than 15
Absolute value is the magnitude of a number without regard to its sign. for example, the absolute value of 5 is 5, and the absolute value of -5 is also 5!
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=-
