w+5=8 because 3+5=8 so
w+5=9 because we put w as 4
w +5=10 so w is 5
Answer:
F(1,5)
Step-by-step explanation:
This is a vertical parabola.
The vertex is at (1,4).
The directrix is y=3.
The distance from the vertex to the directrix is p=1
The focus is (1,4+p), which is (1,4+1)
Therefore the focus is (1,5)
Answer:
The difference is that the height of the cone is divided by 3
Step-by-step explanation:
formular of cylinder
Formular of a cone
Because this shape has 2 right angles, we can confirm that it has one set of parallel sides and is a trapezoid. Therefore, use the formula for area of a trapezoid, .5(b1+b2)(h)
.5(1+6)(12)
.5(7)(12)
42 units^2
