They can complete 1/2 of the order in 4 days
Explanation:
since they can complete the full order in 8 days just divide by 2 to get an answer
Answer:
t = 3.1 seconds
Step-by-step explanation:
Set the equation h = -16t^2 + 40t + 30 equal to 0 (0 represents ground level).
Then h = -16t^2 + 40t + 30 = 0
Applying the quadratic formula with a = -16, b = 40 and c = 30,
-40 ± √( 1600 - 4[-16][30] )
t = -----------------------------------------
2(-16)
-40 ± √ 3520
t = -------------------------
-32
-40 - 59.33
Only the positive t value makes sense. It is t = ------------------
-32
t = 3.1 seconds

2) 4.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
a). By applying tangent rule in the triangle,
tanθ = 
θ = 
θ = 36.87°
Therefore, θ < 45°
b). By using cosine rule in this triangle,
cosθ = 
cosθ = 
θ = 45°
c). By using tangent rule,
tanθ = 
θ = 
θ = 75.96°
θ > 45°
