4/87 is around 0.046
13+0.046=13.046
13.046 to the nearest half is 13
Answer:
The time(s) the ball is higher than the building: Interval (0,4)
Step-by-step explanation:
s(t)=-16t^2+64t+400
Determine the time(s) the ball is higher than the building:
s(t)>400
-16t^2+64t+400>400
Subtracting 400 both sides on the inequality:
-16t^2+64t+400-400>400-400
-16t^2+64t>0
Multiplying the inequality by -1:
(-1)(-16t^2+64t>0)
16t^2-64t<0
Fatorizing: Comon factor 16t:
16t(16t^2/16t-64t/16t)<0
16t(t-4)<0
t is greater than zero:
t>0→t-4<0→t-4+4<0+4→t<4
Then t>0 ant t<4:
Solution = (0, Infinite) ∩ (-Infinite, 4)
Solution = (0,4)
The percent increase is 25%.
Step-by-step explanation:
Given,
Games won last year = Old value = 16
Games won this year = New value = 20
Difference = New value - Old value
Difference = 20-16 = +4
The positive sign indicates increase.
Percent increase = 
Percent increase = 
Percent increase= 
Percent increase = 25%
The percent increase is 25%.
