The shape of the Gateway Arch in St. Louis, Missouri resembles a parabola with the
equation h - 0.00635x^2 +4.0005x -0.07875,
where h is the height in feet and z is the
distance from one base in feet,
What is the distance from one base of the arc
to the other? This answer to the nearest foot is equal to u.

630 ft

Step-by-step explanation:

The equation of the parabola shaped arc is given as:

In a parabola, the line of symmetry divides the parabola into two equal parts.

Therefore, to find the distance from one base of the parabola to the other, we simply multiply the x-value at the line of symmetry by 2.

For a quadratic equation of the form :

Therefore, distance from one base of the arc  to the other

In our given equation:

The distance from one base of the arc  to the other is 630 ft.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24
