MODELING WITH MATHEMATICS The Uniform Federal Accessibility Standards specify that a wheelchair ramp may not have an incline greater than 4.76º. You want to build a ramp with a vertical rise of 8 inches. You want to minimize the horizontal distance taken up by the ramp.
Label the diagram (in inches) to show the approximate dimensions of your ramp. Round decimal answers to the nearest tenth.
4.76

i am thinking c. sorry if im wrong .

step-by-step explanation:

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
