the answer is 58.8 so i think these the answer
2+20t-5t^2=12
5t^2-20t+10=0
t^2-4t+2=0 complete the square
t^2-4t=-2
t^2-4t+4=2
(t-2)^2=2
t-2=±
t=2±
t≈(0.586, 3.41)
Answer:
y= 5.99(g) + 6.49(u)
Step-by-step explanation:
1) First you determine the variable in the equation $5.99, $6.49, g, and u.
2) Then analyze the equation and identify that each gold baseball trophy (g) is worth $5.99, and each uniform baseball trophy (u) is worth $6.49 each.
3) Since you are finding the total you insert a plus sign.
First, find the radius
