Answer:
C
Step-by-step explanation:
First of all multiple all the values by 12 then convert it into the appropriate measurement and that will be your answer
Answer:
you should put 20 points if you answer the question+ brainliest. if you dont people will think its free for example. I have a question you can answer to get your points back, just say something random. Sorry I couldnt help you but thanks for the points.
Step-by-step explanation:
On your calculator, make sure you're in radian mode, not degree mode, that you are in a trig coordinate plane (do this by hitting "zoom" and choosing ZTrig), and when you enter the function into the "y =", you have to enter it in like this: 7cos(2x)-3. Hit "graph" and you'll see that the wave goes through the x-axis in 4 places within your specified interval. Hit 2nd and "trace" and then "zero". Move your cursor so it's just above the x-axis where the curve goes through and hit enter, then move it so it's just below the x-axis where the curve goes through and hit enter again. Hit enter a 3rd time, and you SHOULD see that your x has a value while y = 0. Do that for all of the places where the curve goes through the x-axis. That's how you find the zeros of a trig curve (or any curve, for that matter) on a calculator. The zeros are the solutions. If this was solvable like a regular equation, using trig identities and right triangles, you wouldn't have to use your calculator. But just like when you go to factor a second degree polynomial and you're having trouble with it you can use the quadratic formula and it's never-fail, neither is your calculator.
