<u><em>Answer:</em></u>
y^2 = 28x
<em><u>Step-by-step explanation:</u></em>
Since the directrix is horizontal, use the equation of a parabola that opens left or right.
(y−k)^2 = 4p(x−h)
Find the vertex.
(0,0)
Find the distance from the focus to the vertex.
p = 7
Substitute in the known values for the variables into the equation
(y−k)^2 = 4p(x−h).
(y−0)^2 = 4(7)(x−0)
Simplify.
<em>y^2 = 28x</em>
Answer:
because 8/4=2
Step-by-step explanation:
4/4=1
8/4=2
it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.
This is simply 609 000 divided by 11 000
609 000 / 11 000.
Cancel each of the 3 zeros at the top and bottom
= 609/11
Use a calculator
= 55.3636...
So it goes in approximately 55.36 times.
3/x = 4/3
4x = 9
x = 9/4
5/y = 4/3
4y = 15
y = 15/4 (B)
