If the CO2 concentration level increased from 330 ppm in 1980 to 360 ppm in 1996, by what percentage did the CO2 concentration level increase over that time interval?

Given x = -4 Find y if y = 2sin(2x+3) (*be sure your calculator is in radian mode and round your answer to two decimal place accuracy)

Given x = 10 find y if

y=.02x² + 2.4x + 124

If X=22 find K

k= 0.0158x^{2 + 1.27x + 342 + 3.5sin (6.25x - 0.5) - please calculate in radian mode and round your answer to}
