Answer:
what's the question?
Step-by-step explanation:
Answer:
sin30° and cos60°
Step-by-step explanation:
We can see that we can use multiply trig identities to solve for <em>r</em>:
sin30° = r/20
r = 20sin30°
cos60° = r/20
r = 20cos60°

Answer:
y = 4.
Step-by-step explanation:
I suppose that this question relates to the image that can be seen below.
In the image, the green line represents the exponential function and the blue line represents the linear function.
The y-value after which the exponential function will always be greater than the linear function is the y-value where bot graphs intersect, such that after that point, the blue line starts increasing fast, and is always above the green line.
In this case, this point is the second intersection, and we can see that this intersection happens in the point (2, 4)
Remember that the usual notation for points is (x, y).
Then the y-value after which the exponential function will always be greater than the linear function is y = 4.
To determine the time that the object will hit the ground, you would need to substitute h = 0, since it hits the ground with respect to the building or the height it was dropped from it would be 0.
The time initially is 0, as this is the point that the object is first dropped off from a height of 116 feet.
Solve for t, that will provide the time it takes for the object to hit the ground.
Since the time that the object is dropped is 0, at the top, and the time that the object is on the ground is some value that you calculate.
The duration of time that it takes for the object to hit the ground is the difference between the 2 heights.
