f(x) = 7
x=6
look on the table and find where f(x)=7 on the bottom row, the number with it is 6
The coordintates of the point mark the opposite-leg and adjacent leg of a right triangle.
The opposed-leg is the y-coordinate, this is 3.
The adjacent-leg is the x-coordinate, this is 4.
The tangent of the angle q is given by:
tan(q) = y-coordinate / x-coordinate = 3 / 4 = 0.75
Answer: 0.75
Answer:
2
Step-by-step explanation:

Answer:
It took 8 seconds for the leaf to reach the ground.
Step-by-step explanation:
The height of the leaf in feet can be found using the function:
y = -3.5*x + 28
where x is the time in seconds the leaf has been in the air.
You want to know how long it took for the blade to reach the ground. That is, the time it took for the blade to reach a height of 0 feet. So, replacing this value in the expression:
0= -3.5*x + 28
and solving you get:
-28= -3.5*x
(-28)÷ (-3.5)=x
8=x
<u><em>
It took 8 seconds for the leaf to reach the ground.</em></u>
It increased by 100%.
