Let julia's age be x
Let Kara's age be 4x
x+4x=13
5x=13
x=13/5

Set s(t) = 0 which means it hits the ground. The formula doesn't fit the parameters given as it shows that the pitcher is standing on something 37 feet high.
<span>s(t)=-16t^2+140t+37 and has an initial velocity of 140.
Graphing or solving this, t= 9 seconds when it hits the ground.
The velocity V(t) is the derivative of s(t)
V(t) = -32t+140
V(9) = -148 ft/second which is going down

Answer:
120 students students could be expected to not be wearing a jacket
Step-by-step explanation:
Based on this, we can work with the assumption that 3/5 of the students that entered the stadium were wearing jackets.
Given that the total population of students that attended the game is 300
This means that 3/5 of the 300 = 180 students.
180 students were estimated to be wearing jackets.
The number of students that were without jackets is 300 - 180 = 120 students
I believe it’s 20, hope this helps!
