Answer:
x = 1/20 y^2
Step-by-step explanation:
This is a rightward opening (sideways ) parabola
Directrix = x = -5
Distance formula form point x,y to directrix and focus are equal:
(x - -5)^2 = (x-5)^2 + y^2
x^2 + 10x + 25 = x^2 - 10x + 25 + y^2
20x = y^2
x = 1/20 y^2
I can't factor that.
Is the equation input correctly?
Answer:
110 cm
Step-by-step explanation:
So if we know the diameter, which is 35 cm, we can use the formula π*d. So we would take the diameter and put it in the place of d. So it would be pie times 35. Which would result in us getting 109.96. And this rounded to the nearest tenth would be 110. So The circumference would be 110 cm.
<span>In order to find the solution, we must solve for 'x' in the initial equation. What we do to one side of the equation to isolate 'x', we must do to the other. If we subtract 5x from both sides were are left with x - 2 = 3. We then add 2 to both sides to completely isolate 'x' and are left with x = 5. This is in the replacement set and is one of the provided solutions, D.</span>
