Answer:
Option A , (0, 20); y equals one over eighty times x squared plus 20
Step-by-step explanation:
The equation of parabola is given by
(X-h)^2 = 4p(Y-k)^2
In this case h = 0
So we get
Y = X^2/4P +k
Focus point is (h, p+k) , p+k = 40
Hence h, k = (0,20)
P = 40-k = 20
Equation Y = X^2/80 +20
Hence, option A is correct
Answer:
36
Step-by-step explanation:
7x+4 = 15x-12
7x = 15x-16
-8x = -16
-8x/-8 = -16/-8
x = 2
BD = 15x-12 + 9x
BD = 15(2)-12 + 9(2)
BD = 30-12 + 18
BD = 18 + 18
BD = 38
Answer:
x = 9.25
y = 13.5
Step-by-step explanation:
area = 33
let length be y and width be x
2x - 5 = y
area of rectangle = length * breadth
(2x-5)(x)=33
2x²-5x=33
2x²-5x-33=0
solving quadratic equation
x = 9.25
y = 13.5
