Which is the directrix of a parabola with equation x^2=8y

1 answer:

4 0

According to the definition, is a parabola is in the standard form of (x-h)^2<span>=4p(y-k), then the directrix is y=k-p. In this case, the parabola function is x^2=8y, so h=0, p=8/4=2, k=0. Plug the values of h, p, k, into y=k-p, the directrix is y=-2.</span>

Whats this i have been struggling for this . 5(3x−2)=−x−10

Inessa05 [86]

Answer:

$x=0$

Step-by-step explanation:

$5(3x-2)=-x-10~(Given)\\\\15x-10=-x-10~(Distribute~5~to~3x-2)\\\\15x-10+x=-x-10+x~(Add~x~on~both~sides)\\\\16x-10=-10~(Simplify)\\\\16x-10+10=-10+10~(Add~10~on~both~sides)\\\\16x=0~(Simplify)\\\\\frac{16x}{16}=\frac{0}{16}~(Divide~16~on~both~sides)\\\\x=0~(Simplify)$

The radius or diameter is given. Find the missing measures to the nearest hundredth.

Fynjy0 [20]

Answer:

For any circle of radius r

The diameter of the circle = two times of the radius = 2r

And The Circumference= C = 2πr

14. If r = 8

So, d = 2r = 2 * 8 = 16 cm

C = 2πr = 2 * π * 8 = 50.27 cm (to the nearest hundredth.)

15. If d = 9 m

So, d = 2r

∴ r = d/2 = 9/2 = 4.5 m

And C = 2πr = 2 * π * 4.5 = 28.27 m (to the nearest hundredth.)

What strategie do u use to divide 98 divided by 7

sineoko [7]

You can break 98 into 2 49's. Hopefully, we know that 49 is 7 * 7, so 98 is 7 * 14. The correct answer is 14. :)
