A fountain on a lake sprays water in a parabolic arch modeled by the equation y= -0.3x^2 +3x. A beam of light modeled by the equ
ation -2x+5.5y=19.5 passes through the fountain to create a rainbow effect. f the beam cuts the water spray at points A and B, such that point B is higher than point A, what distance from the ground level is point A?

ANSWER
4.1 units to the nearest tenth.
EXPLANATION
The graph of the two functions are shown in the attachment.
The coordinates of point A is (1.6,4.1).
The coordinates of point B is (7.1,6.1)
The x-axis represents the ground level.
The distance of point A from the ground level is how far the y-coordinate of this point is from the x-axis.
Which is |4.1-0|=4.1

Answer:
2/45
Step-by-step explanation:
0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: . Multiplying the two fractions results in 4/90 which can be simplified to 2/45.
