Answer:
16 feet height of the arch at a distance of 30 feet from the center
Step-by-step explanation:
Given data
span = 100 feet
height = 20 feet
to find out
the height of the arch at a distance of 30 feet from the center
solution
we know the equation of elliptical i.e.
x²/a² + y²/b² = 1 ......................1
from question we can say that length of major axis i.e
2a = 100
so a = 50
and height is
b = 20
so put a and b in equation 1
x²/a² + y²/b² = 1
x²/50² + y²/20² = 1
x²/2500 + y²/400 = 1
y²/400 = 1 - x²/2500
y / 20 =
y = 20
so now take value 30 for function f(30)
f(30) = 20
f(30) = 20
f(30) = 16 feet
so 16 feet height of the arch at a distance of 30 feet from the center
Answer:
Step-by-step explanation:
The points show a high postive correlation with a linear model, whose slope is constant:
The numerical value predicted by the fit line is:
I seef(x) between 0 to 1 is goes to xfinity but in the negative direction
We can say it is large neagtive numbet when x is between 0 and 1
