1. Kelly is playing with her drone, which she got from Santa last Christmas. When she flies her
1 answer:
Answer: 686.86 feet
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the next trigonometric function.
Tan α = opposite side / adjacent side
Where α is the angle of elevation of Kelly's view, the opposite side (x) is the maximum height of the drone, and the adjacent side is the horizontal distance between Kelly and the drone when it hits the ground.
Replacing with the values given:
Tan 70 = x/ 250
Solving for x
tan70 (250)=x
686.86 ft = x

Answer:
True.
Step-by-step explanation:
The explicit form for an arithmetic sequence is:
where is the first term and
is the common difference.
The common difference here is 2 because the y's are going up by 2 while the x's are going up by 1.
Yes, the common difference is the slope.
So we have d=2.
The first term is 9.5 because that is what happens when x=1.
x is n.
y is .
So the answer is true.

You can also verify by plugging in numbers for n and see if you get the outputs mentioned in the pairs given:
Let n=1:
Let n=2:
Let n=3:
Let n=4:
Let n=5:
Let n=6:
We have confirmed that we get all 6 of the mentioned points using the equation they gave.
