20 is the area as long as y is the measure of the base
If the scale is 32 to 1, that means it is 32 times bigger than the actual thing. So if the model is 196 inches long, then the actual heart is 196/32 inches long. This equals 6.125.
Answer, rounded to the nearest whole number: 6 inches.
Step-by-step explanation:

Multiply by the inverse of denominator
Add both sides
The problem gives you X, so replace X witht he given vaule and solve for y:
y = -0.1x^2 + 4X
X = 40
y = -0.1(40)^2 +4(40)
y = -0.1(1600) + 160
y = -160 + 160
y = 0
Answer:
Step-by-step explanation:
Because this quadratic equation would have the curve-down form of:
where a and b are positive coefficient.
If we let the peak (250 ft) of the curve be at x = 0. Then
Also at the begins and ends, thats where y = 0, the 2 points are separated by 100 ft. So let the begin at -50 ft and the end at 50ft. We have
Therefore, the model quadratic equation of our path would be
