Please Help!! A Softball is thrown from a height of 20 feet at an initial velocity of 48 feet per second

1) Write the equation?
2) Find the height at t=3 second?
3) Find the vertex?
4) Find the axis of symmetry?
5) Find the time when it goes to the ground?
6) What is the maximum Height?
7) How long it takes to get to the maximum height?

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

125 yards

step-by-step explanation:

i take 75 plus 50.

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

mrb

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
