Answer:
Distance between the observer and the red car is ![250 Sin \frac{\pi}{3}t](https://tex.z-dn.net/?f=250%20Sin%20%5Cfrac%7B%5Cpi%7D%7B3%7Dt)
Step-by-step explanation:
Diameter of field = 500 m
Radius of field =![\frac{Diameter}{2}=\frac{500}{2}=250 m](https://tex.z-dn.net/?f=%5Cfrac%7BDiameter%7D%7B2%7D%3D%5Cfrac%7B500%7D%7B2%7D%3D250%20m)
Let R be the radius and the speed at which the car completes race be w
So,![w=\frac{2\pi}{T}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2%5Cpi%7D%7BT%7D)
Car finished 5 laps in minutes = 30
Car finished 1 lap in minutes = ![\frac{30}{5}=6](https://tex.z-dn.net/?f=%5Cfrac%7B30%7D%7B5%7D%3D6)
So, ![w=\frac{2\pi}{6}=\frac{\pi}{3}](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B2%5Cpi%7D%7B6%7D%3D%5Cfrac%7B%5Cpi%7D%7B3%7D)
Refer the attached figure
Angle between car and observer = wt
So, Distance between the observer and the red car is give as A sin wt
So, Distance between the observer and the red car=![250 Sin \frac{\pi}{3}t](https://tex.z-dn.net/?f=250%20Sin%20%5Cfrac%7B%5Cpi%7D%7B3%7Dt)
Answer: C
Step-by-step explanation:
the normal distribution is symmetric about its mean.
so answer c) must be true.
20% is 1/5 more so it is 1 1/5 times the size of the smaller one. 1 1/5 is 1.2 as a decimal (also 120% divided by 100).
Let's take the smaller bottle to be y.
x=1.2y
x=1.2*5.4=6.48 ounces.
Answer:
the answer is 4
Step-by-step explanation:
32÷8=4 therefore b is 4
