18/20 is 90%
You can use a calculator to divide 18 and 20 and you will get 0.9 which is 90%
Or. simplify by dividing the top and bottom by 2, to get 9/10 which is still 90%
:)
It takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
<h3>What is the axis of symmetry?</h3>
Axis of symmetry is a line that divides an object into two equal halves, thereby creating a mirror-like reflection of either side of the object.
1. The function is a parabola of the form . The the formula for the axis of symmetry of a parabola is . We can infer from our function that a= -16 and b = 48, so lets replace those values in our formula:



x = 1.5
We can conclude that to the left of the line of symmetry the ball is reaching its maximum height, and to the right of the line of symmetry the ball is falling.
2. Lets check how much time the ball takes to reach its maximum height and return to the ground. To do that we are going to set the height equal to zero:


t = 0, (t-3) = 0
t = 0, t = 3
From our previous point we know that the ball reaches its maximum time at , which means that it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

Answer:
27 I do believe so sorry if im wrong
Step-by-step explanation:
Q=2*s*L(T2-T1)/ (R2/R1)
1500000=2*30*10(275-22)/(R2/6)
1500000=600(253)/(R2/6)
1500000R2=600*253*6
1500000R2=910800
R2=910800/1500000
R2=0.6072.
Answer:
M
Step-by-step explanation:
The table of x, y values for a proportional relationship show that y is 0 when x is 0. This applies to the second table (M).
