Answer: 1 is 5.7
2 is 21.75
3 is 8.8
Step-by-step explanation:
here ya go
283 rounded to the nearest ten is 280
When rounding to the nearest ten look at the number to the right of the place you are rounding. In this case it is the 3. If the number is 5 or higher you go up to the nearest ten. If the number is lower than 5 like it is in this number you round down to the nearest ten.
We are asked in the problem to solve for x in the expression tan(x+π)+2sin(x+π) = 0. tan theta is equal to sin theta over cos theta. Hence, the expression results to tan (x+π) = sin (x+π) / cos (x+π) = -2sin (x+π). Thus, 1/cos (x+π) = -2. cos (x+π) = -1/2, cosine becomes negative in the third and fourth quadrants. cosine is 1/2 when the terminal angle is pi/3. x is equal to pi/3 then and 5 pi/6.
Answer:
D, Y=2x-4
Step-by-step explanation:
The easiest way to solve this is by substitution. Plug in 3 into the X of each equation to see if you get 2 as your outcome. Double check by doing the same with 8 and seeing if 12 is the outcome. Once you do this, problems like the one should be a piece of cake.
