Can someone please answer these 4 math questions, I’m failing Please help
Thank you so much

The chs baseball team was on the field and the batter popped the ball up. the equation b(t)=80t-16•16+3.5 represents the height of the ball above the ground in feet as a function of time in seconds. how long will the catcher have to get in position to catch the ball before it hits the ground? round to the nearest second

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x
