Answer:
t = 0.293 s and 14.52 s
Step-by-step explanation:
The heights of the ball in feet is given by the equation as follows :
Where t is the number of seconds after the ball was thrown.
We need to find is the ball 18 ft above the moon's surface.
Put S = 18 ft
It is a quadratic equation. Its solution is given by :
So, the ball is at first 0.293 s and then 14.52 s above the Moon's surface.
Flip the second fraction and change the fraction into multiplication
Also, change 2 1/2 into a improper fraction
2 1/2 = 5/2
(5/2)/(5/8) becomes 5/2 x 8/5
Multiply across
5 x 8 = 40
------- -----
2 x 5 = 10
Simplify 40/10
40/10 = 4
4 is your answer
hope this helps
This is actually an easy one.
4 day= 24 hours X 4 = 96 hrs.
4560 = 96 hrs.
4560/96 = per hr.
47.5 watts per hr.
Since 1 day = 24 hrs, 47.5 X 24 = 1140 Watts per day.
See? Simple and easy if you solve parts at a time!
Answer:
it cost 80 dollars
Step-by-step explanation:
cost per bag for X brand =25 $
cost per bag for y brand = 20$
minimize Z=(25X +20 y)
further formulate the problem
the given constraints are
2x + y equal 12
2x + 9y equal 36
2x + 3y equal 24
well on the graph given plot of the constraints
the corner points are
(0;0)
(6;0)
(0;4)
(9;2.5)
minimum z occurs at (0:4)
value of Z(minimum cost)=80$
The slope intercept form is y=-x-5
