Difference between 25 and 35 = 35 -25
= 10
Then
percentage by which 25 is less than 35 =(10/35) * 100
= (2/7) * 100
= 200/7
= 28.57 percent
So 25 is 28.57% less than 35.This is the only clear way of solving these kind of problems. I hope you
have understood the method used to solve this problem. Hopefully you
can do such type of problems without needing any help.
The general form of the equation we need to find is (x - h)^2 = 4p(y- k).
The center is the distance between the directrix and focus.
So, center (h, k) = (3, 3/2) .
P = distance from center to the focus and it just so happens to be 1.5.
We now plug everything into the formula given above.
(x - 3)^2 = 4(1.5)(y - 3/2)
(x - 3)^2 = 6(y - 3/2)
Done!
Answer:
0.53
Step-by-step explanation:
Answer:
(0,5)
Step-by-step explanation:
Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.
Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.
The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).
