Hyun woo is riding a ferris wheel. h t h(t) models his height (in m m) above the ground, t t seconds after the ride starts. here, t t is entered in radians. h t 1 0 cos 2 ? 1 5 0 t 1 0 h(t)=? 10cos( 150 2? ? t)+10 when does hyun woo first reach a height of 1 6 m 16 m? round your final answer to the nearest whole second.

Pick the expression that matches this description: a polynomial of the 5th degree with a leading coefficient of 7 and a constant term of 6 (choice a) 7x^5+2x^2+6 (choice b) 7x^6−6x^4+5 (choice c) 6x^7−x^5+5 (choice d) 6x^5+x^4+7

This is so hard and it’s for a test

Someone answer asap for ! a ball is rolled down a ramp. the height, f(x), in meters, of the ball x seconds after it is released is modeled by the function f(x) = x²- 10x + 25 for all values of x from 0 to 5. which statement about the ball is true? a. the maximum height of the ball is 5 meters b. the height of the ball increases from 0 to 5 meters above the ground. c. the ball has traveled 5 meters when it reaches the bottom of the ramp. d. the ball has been traveling for 5 seconds when it reaches the bottom of the ramp
