Answer:
Vertex: (-2, 2)
Step-by-step explanation:
The x-coordinate of the vertex would be as follows;
x = -b/2a = 8/2(-2) = -8/4 = -2
respectively the y-coordinate of the vertex would be y(-2) = -2(-2)^2 - 8(-2) - 6 = -2(4) + 16 - 6 = - 8 + 10 = 2
Your vertex would be a maximum of (-2, 2)
* I say maximum as the coefficient of x^2 is -2, and it is less than zero so the parabola opens downward
Answer:
750ft^3
Step-by-step explanation:
Given:
Volume of cone a=48ft^3
Radius of a=12 inches
Radius of b=30 inches
Volume of cone b=?
The linear state factor=ratio of the radio
=30/12
=2.5
Volume scale factors=linear state factor^3
=2.5^3
=15.625
Volume of Cone B= volume of Cone A × volume scale factor
=48 × 15.625
= 750 ft^3
