Answer _
It is perpendicular to the equation y=15x-3.
Answer:
Step-by-step explanation:
Volume of cylinder = πr2h
height =6 inches
r is the radius of the cylindrical container
48 in3 =πr2 * 6
6= πr2
π= 22/7
6*7/22=r2
42/22 =r2
21/11=r2
r2= 21/11
r = SQRT(21/11)
r= 1.38169855942
Answer:
The height of the highest point of the arch is 3 feet.
Step-by-step explanation:
The complete question is:
A dome tent’s arch is modeled by y= -0.18(x-6)(x+6) where x and y are measured in feet. To the nearest foot, what is the height of the highest point of the arch.
Solution:
The expression provided is:
The equation is of a parabolic arch.
The general equation of a parabolic arch is:
So,
a = -0.18
b = 6.48
c = 0
Highest point of the parabolic arch is the vertex of the parabolic equation if <em>a</em> < 0
.
As <em>a</em> = -0.18 < 0, the ordinate of vertex of equation will give the height of highest point of arch.
For a parabola the abscissa of vertex is given as follows:
⇒
Compute the value of <em>y</em> as follows:
Thus, the height of the highest point of the arch is 3 feet.
