Answer: If you have solved to get x=6 just plug that back into the problem. You get 50
Step-by-step explanation:
A is 7 4 and 3..B is the same...This is my first time with this kind of problem....
Hey there! :D
When powers are outside the parenthesis, you multiply them. When they are not, you add them.
(y^3)^2 * y^7
3*2= 6
y^6*y^7
Add the powers.
y^13= the simplest form
I hope this helps!

1 meter is the same as 100 centimeters, so since Liz jumped 100 centimeters, and Alana jumped 132, Alana jumped higher.
Answer:
6 ft
Step-by-step explanation:
Since the shape of the cables on the bridge are to open up, the standard equation of the parabola produced is given as:
(x - h)² = 4p(y - k)
Where (h, k) is the vertex and focus is at (h, k+p)
From the question, the point (0, 2) is the vertex and point (50, 27) lie on the parabola. Hence:
(x - 0)² = 4p(y - 2)
x² = 4p(y - 2).
Sinc the tower is 100 ft apart and 27 ft height, hence the point 100/2 = 50 ft and 27 ft lie on the parabola
To find p, use (50, 27)
50² = 4p(27 - 2)
2500 = 4p(25)
100p = 2500
p = 25
hence:
x² = 4(25)(y - 2)
x² = 100(y - 2)
At a point of 20 feet (i.e x = 20), y is the height of the cable, hence:
20²=100(y-2)
400 = 100y - 200
100y = 600
y = 6
The height is 6 ft at a point of 20 ft
