Answer:
2879ft
Step-by-step explanation:
The level runway (x), height gained (h), and distance travelled (r) form a right-angled triangle with base angle
10
∘
.
We may hence use trig ratios to solve for any of the unknowns, in particular for the distance r as follows :
First graph it
#1
Maximum height is the y coordinate of vertex
- (2,144)
Max height
- 144m
#2
Time is the x coordinate of vertex
- 2s
#3
- y is 0
x intercepts are the solutions
- (-1,0)U(5,0)
Take it positive
- t=5s
#4
put in function
- y=-16(1)+64+80=-16+144=128ft
