Answer:
b.7
Step-by-step explanation:
you take the three and substitute that in for x. 2(3) + 1
2(3)=6 then add 1
<h3>
Answer: c. 8(y-6) = (x-2)^2</h3>
Explanation:
The directrix is horizontal, so the axis of symmetry is vertical. We'll have an x^2 term. The vertical distance from y = 4 to y = 8 is 4 units. Cut this in half to get 2, which is the focal distance p = 2.
The point (2,4) is directly below (2,8), and the point is on the directrix. The midpoint between (2,4) and (2,8) is (2,6). This is the vertex.
(h,k) = (2,6)
4p(y-k) = (x-h)^2
4*2(y-6) = (x-2)^2
8(y-6) = (x-2)^2
Answer:
30%
Step-by-step explanation:
18 / 60 = .3 * 100 = 30%
270 degrees this because when you count each angle it is 90 degrees then 180 degrees then 270
Complete Question
We have two stacks of styrofoam cups. One stack has 6 cups, and its height is 15 cm. The other stack has 12 cups, and its height is 23 cm. How many cups are needed for a stack with a height of 50 cm
Answer:
37.5 cups
Step-by-step explanation:
Height 1 = 15cm
Number of cups = 6
Height 2 = 23 cm
Number of cups = 12
Hence:
H1 - H2/N1 - N2
= 15 - 23/6 - 12
= -8/-6
= 4/3
The number of cups that are needed for a stack with a height of 50 cm is calculated as:
50 cm ÷ 4/3
= 50 × 3/4
= 37.5 cups
