Answer:
yes it is right
Step-by-step explanation:
good job
<span>Given that the directrix of the parabola is at y = -8 and the focus is at point (8, 16), this means that the parabola opens upwards and the x part of the equation of the parabola is squared. The x-value of the vertex of a parabola is the same as the x-value of the focus while the y-value of the vertex is half the sum of y-values of the focus and the directrix. Therefore, the vertex of the given parabola is (8, (16 - 8)/2) = (8, 8/2) = (8, 4).</span>
Answer:
x = 4.
Step-by-step explanation:
The 2 trapezia are similar so we have:
x/ 10 = 2/5
5x = 20
x = 4.
Let, the number = x
It would be: x * 35% = 35
x * 0.35 = 35
x = 35 / 0.35
x = 100
In short, Your Answer would be 100
Hope this helps!
