Answer: The top of the Crane is 31 feet above the ground.
Step-by-step explanation:
When it is fully extended, the crane arm forms a 30 degree angle with a line parallel to the ground. This means that a right angle triangle is formed. The length of the Crane's arm represents the hypotenuse. The horizontal distance represents the adjacent side of the right angle triangle. The distance, h of the top of the Crane from the ground represents the opposite side of the right angle triangle.
To determine h, we would apply
the Sine trigonometric ratio.
Sin θ, = opposite side/hypotenuse. Therefore,
Sin 30 = h/62
h = 62Sin30
h = 62 × 0.5
h = 31 feet

im pretty sure that is it
Answer:
168.4953 (m/s)
Step-by-step explanation:
a(t)=x''(t)=(0.0951t⁴-0.101t³+0.837t²+3.87t-9.37)''= =4*3*0.951t²-3*2*0.101t+2*0.837 =11.412t²-0.606t+1.674.
a(3.85)=11.412*3.85²-0.606*3.85+1.674=168.4953
There are seven people who each want half an ounce of brocolli. So, you multiply 1/2 by 7, which would be around 3 and 1/2. The actual number, will be 3 and 1/2 though as well.
