Answer:
The new ramp must be 54 inches long than the old ramp to meet the requirement of the new law
Step-by-step explanation:
Old height to length ratio is:
h : l = 2 : 15.
Height of old ramp h = 12
Length of old ramp can be find out by putting h = 12 in the above ratio
Length of old ramp = 90
Height to length ratio by current law:
h : l = 1 : 12
Height will be the same i.e. h = 12
Length of new ramp = 144
How much longer the new ramp should be to meet the new ratio law:
New length - Old length = 144 - 90 = 54 inches
Answer:
D
Step-by-step explanation:
Try to remember this formula.
Where a is the vertical multiplier, b is the horizontal multiplier, c is the x coordinate of the vertex, and d is the y coordinate of the vertex.
Since the vertex on the graph is (2,3), c and d have to be 2 and 3.
Also, there are no vertical/horizontal stretches so the a and b values stay at 1.
The final equation would come out to
