Answer:
45 m
Step-by-step explanation:
The height at time of launch is at x = 0
Substitute x = 0 into f(x)
f(0) = - 5(0 + 1)(0 - 9) = - 5(1)(- 9) = 45 m
I personally think its 18, please tell me what i did wrong <span />
Answer:
B. 15.4 ft
Step-by-step explanation:
this answer, without any formulas used, can be answered correctly and logically.
answer c, d and e are eliminated as the opposite side cant be greater than the hypotenuse.
now we have to find which is correct between a and b
the answer will be 'B' as the value of sine of an angle keeps increasing as the angle itself increases. thus, giving a bigger value of the opposite side (required height). as 15.4 ft.
mathematically,
sin65° = x/17
17 × sin65° = x
where x is height of the side of the building.
