Answer:
a = 1/25
Step-by-step explanation:
The vertex form of the parabola is
y = a(x-h)^2 +k
where (h,k) is the vertex
y = a(x-2)^2 -4
We have a point on the parabola (-3,-3) so substitute this into the equation
-3 = a(-3-2)^2 -4
-3 = a(-5)^2 -4
Add 4 to each side
-3+4 = a(25) +4-4
1 = 25a
Divide each side by 25
1/25 = a
y = 1/25(x-2)^2 -4
<u>152 cubic ft</u>
Answer:
Volume of solid figure=Volume of
upper cuboid+volume of lower cuboid
=l*b*h+l*b*h=10*4*3+4*4*2=152 cubic ft
X = # of men x + (x + 25) = 115 2x + 25 = 115 2x = 90 x = 45 45 + 25 = 70 so there's 70 women
is positive, and we want to be negative, which together means is an angle that lies in the fourth quadrant.
Use the Pythagorean identity to solve for :
Then by definition of tangent, we have
