Answer:
a number which produces a specified quantity when multiplied by itself.
Step-by-step explanation:
Answer:
mean is 12
Step-by-step explanation:
The mean is another word for average
Add all the numbers together
(5+4+5+4+42) = 60
Divide by the number of numbers. There are 5
60/5 = 12
Answer:
the first one is correct
Step-by-step explanation:
this is the same way as writing 7 to the power of four, but all of the sevens are negative in your case
Answer:
- arc second of longitude: 75.322 ft
- arc second of latitude: 101.355 ft
Explanation:
The circumference of the earth at the given radius is ...
2π(20,906,000 ft) ≈ 131,356,272 ft
If that circumference represents 360°, as it does for latitude, then we can find the length of an arc-second by dividing by the number of arc-seconds in 360°. That number is ...
(360°/circle)×(60 min/°)×(60 sec/min) = 1,296,000 sec/circle
Then one arc-second is
(131,356,272 ft/circle)/(1,296,000 sec/circle) = 101.355 ft/arc-second
__
Each degree of latitude has the same spacing as every other degree of latitude everywhere. So, this distance is the length of one arc-second of latitude: 101.355 ft.
_____
<em>Comment on these distance measures</em>
We consider the Earth to have a spherical shape for this problem. It is worth noting that the measure of one degree of latitude is almost exactly 1 nautical mile--an easy relationship to remember.
Solving the expression 
we get value of x: 
or 
Step-by-step explanation:
We need to solve the equation and find value of x
Solving:
Adding 5/3 on both sides
Simplifying:
Multiply 6/5 on both sides:
So, solving the expression we get value of x: or
