National rides in a circular training seller raider at 16 me a second if the radius of the Excelerator is 8.0 m what is his centripetal acceleration in meters second squared

What is the length x of the side of the triangle below? (hint: use the cosine function)

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
