While you’re at the top of the tower(50 meters up ) you see an ant walking along the edge of the building. If the ant were to walk straight down the side of the tower ( 86 degree lean) u til it reaches the ground, how far would the ant travel? Which trigonometric ration would you use? Use the ratio to find the measurement. Confirm that answer by using the Pythagorean theorem instead of trig ratios.

Look at the following graph of the given equation. determine whether the equation is a function. explain why or why not.

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)

Aspacecraft can attain a stable orbit 300 kilometers above earth if it reaches a velocity of 7.7 kilometers per second. the formula for a rocket's maximum velocity v in kilometers per second is vequalsminus0.0098tplusc ln upper r, where t is the firing time in seconds, c is the velocity of the exhaust in kilometers per second, and r is the ratio of the mass of the rocket filled with fuel to the mass of the rocket without fuel. find the velocity of a spacecraft whose booster rocket has a mass ratio of 20, an exhaust velocity of 2.1 km/s, and a firing time of 15 s. can the spacecraft achieve a stable orbit 300 km above earth?
