X/29 = 2/5.8
(X) x (5.8). (2) x (29)
5.8x = 58
58/5.8
X = 10
Answer:
(1,4),(2,12)
----------
The form is y = ab^x
12 = ab^2
4 = ab^1
------------
Divide the 1st by the 2nd to get:
3 = b
--------
Substitute that into the 2nd equation to solve for "a":
4 = a*3^1
a=(4/3)
-------------
EQUATION:
y = (4/3)*2^x
==================
Step-by-step explanation:
Sure. The function is a parabola. Because the coefficient of the x^2 term is positive, it opens upward. that means that it vertex is a minimum point.
You can verify that the vertex is (0,24). That means that at the point x=0, the height of the bridge is 24m. So if the level water rises below 24 m, the bridge is safe to use.
