for example, a truck driver is asked to load a bunch of tomato crates onto his truck, which can only carry 1 tonne, how is he gonna know the number of tomato crates his truck can carry?
They have to give standards to everything to make life easier, without a measured weight, people may not get equal amounts of food, to put pricing, and some people may be in diet so extra amount of something might harm them... there are so many reasons
We know that sin²x+cos²x=1 so clear cos x cos x=(+/-)√[1-sin²x]
in this problem <span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive </span>sin o=2/5 cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
Step-by-step explanation: So you are finding the perimeter of the circle. You have a radius of 15, the perimeter for a circle is C=2pir. Now we can do C=2pi(15). The answer is 30pi or C=2 x 3.14 x 15= 94.2 Hope this helps.
