Answer:
Step-by-step explanation:
The position function is
and if we are looking for the time(s) that the ball is 10 feet above the surface of the moon, we sub in a 10 for s(t) and solve for t:
and
and factor that however you are currently factoring quadratics in class to get
t = .07 sec and t = 18.45 sec
There are 2 times that the ball passes 10 feet above the surface of the moon, once going up (.07 sec) and then again coming down (18.45 sec).
For part B, we are looking for the time that the ball lands on the surface of the moon. Set the height equal to 0 because the height of something ON the ground is 0:
and factor that to get
t = -.129 sec and t = 18.65 sec
Since time can NEVER be negative, we know that it takes 18.65 seconds after launch for the ball to land on the surface of the moon.

<h2>
Answer:</h2>
The correct options are:
Choice A
Choice C
and Choice E
<h2>
Step-by-step explanation:</h2>
We are asked to find the value of:
60% of 94
We know that: it is represented as:
Choice A)
We know that:
could also be written as:
Since we multiplied and divide by 10 such that:
Hence, option: A is correct.
Choice B)
This option is incorrect.
Since by choice A we get that the correct expression is:
Choice C)
We get:
This option is correct.
Since,
Choice D)
This option is incorrect because the actual expression is:
Choice E)
[/tex]\dfrac{60}{100}\cdot 94[tex]
This is the correct expression.
At first shop the 3 liters of milk cost 2995
cost per liter = cost / volume
cost per liter = 2995 / 3 L
cost per liter = 998 per liter of milk
at second shop the two liters of milk cost 1595
cost per liter = cost / volume
cost per liter = 1595 / 2 L
cost per liter = 797.5 per liter of milk
