Find the point on the parabola y^2 = 8x at which the ordinate is double the abscissa.

aliya0001 [1]

Answer:

Step-by-step explanation:

Let's make a complex of functions

y^2 = 8x

y = 2x

Now let's solve it

(2x)^2 = 8x

4x^2 - 8x = 0

4x(x - 2) = 0

x = 0, 2

y = 0, 4

So the answer is (2, 4)

Hope you like it, study well

Find the circumference of a circle that has a diameter of 5. Use 22/7 for pi

anastassius [24]

The circumference of a circle is $2 \pi r$ since the radius is half of the diameter we can substitute the diameter instead of using 2r. So we get $\pi d$ The we can substitute the given diameter, which is 5 and multiply it by $\frac{22}{7}$ and get $\frac{110}{7}$ .
