Slope does not exist. A zero in the numerator means you have a horizontal line.
Answer:
1/3
Step-by-step explanation:
Of the 15 students in the class, 5 are boys with glasses. The probability of selecting one at random is 5/15 = 1/3.
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)
If you would like to know how many glasses of water does Evelyn drink in a year (1 year = 52 weeks), you can calculate this using the following steps:
8 glasses of water per day
56 glasses of water per week
x glasses of water per year = ?
x = 56 * 52 = 2912 glasses of water per year
Result: Evelyn drinks 2912 glasses of water per year.
