= 8 3/4 Answer
Answer:
22.18
Step-by-step explanation:
c squared = a squared + b squared - 2ab cos c
or a instead of c in this case.
144+225-360(-0.342)
square root 492.12
9514 1404 393
Answer:
cos(θ) = (5√74)/74
Step-by-step explanation:
The length of the hypotenuse is given by the Pythagorean theorem:
h = √(5² +7²) = √74
The cosine of the angle is the ratio of the adjacent leg to the hypotenuse:
cos(θ) = 5/√74 = (5√74)/74
Hey there. Discrete data is usually date which is counted. Continuous data is data that can be measured, and can take any type of value. So for this, a) Continuous, b) Discrete c) Continuous, d) Discrete
Hopefully this should be right! :)
Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers.
Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)
For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour.
So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added.
Now just divide the size of the vat by that number, and you find your answer.
70 gallons / 3 gallons per hour = 23 1/3 hours.
