Answer: 180
Explanation: For the first number of the combination you have 60 possible options, because you need three numbers for the combo, times it by three.
Answer:
(-7,4]
Step-by-step explanation:
I'm going to assume that you need this in interval form
The domain is just asking for all the possible x values
The x value that's furthest to the left is -7 and because it's an open circle we write ( instead of [
the furthest to the right the line goes is 4 and because the circle is closed it's written with ]
but it all together and get
(-7,4]
Answer:
120x138 in or 11.5x10 feet
Step-by-step explanation:
Step 1:
convert the feet to inches
10(feet)*12(inches)=120 inches
Step 2:
120(width)+18(length)=138 inches
Step 3:
width: 120 in OR 10 feet
length: 138 inches OR 11.5 feet (when divided by 12)
Hope this helps!
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.
The first working out is correct, z = 3
