Height covered by the plane=h= 500 feet
Distance covered by the plane along the ground=d= 2 mile
Now, convert the mile into feet,
1 mile = 5280 feet
2 mile = 10560 feet
Now, use the formula
h= d tanθ
tanθ= h/d
tanθ= 500/10560
tanθ= 25/528
Take the tan⁻¹ on both side,
θ= tan⁻¹(25/528)
θ =2.71°
#3 is not a function because there are two answers for one out put
#4 is a function because it is a straight line
Answer:
y=2x-4
Step-by-step explanation:
Step-by-step explanation:
x2 - 4x - 5
First we will multiply 5 by 1 the answer is 1 now we have to find the factors of 5 so it is just 5 and 1 so
x2 - 5x + x - 5
x ( x - 5) + 1 ( x - 5)
(x + 1) and ( x - 5) are the factors
