The answer is 144.44 because the circumference of a circle is pi X diameter
To determine what the value of X is simply use the appropriate trigonometric ratio, which in this case is cos.
Cos 21 = 3/X
X • cos 21 = 3
X = 3/(cos 21)
X = 3.123 about 3.1
The value of X to the nearest tenth would be about 3.1.
Answer:
the answer is 5y
Step-by-step explanation:
the 5 is the number that is being multiplied (y) is the number of friends
9514 1404 393
Answer:
y = -x -12
Step-by-step explanation:
The slope of the line you want is the same as the slope of the line you have: -1. Then the point-slope equation of the line is ...
y -k = m(x -h) . . . . . . line of slope m through point (h, k)
y -(-7) = -1(x -(-5))
y = -x -5 -7 . . . . subtract 7, eliminate parentheses
y = -x -12 . . . slope-intercept equation
Answer:
When selecting subsets of a larger set in which order is not important, you are finding the number of combination of n elements taken r at a time.
Step-by-step explanation:
We have to fill the blank.
When selecting subsets of a larger set in which order is not important, you are finding the number of combination of n elements taken r at a time.
Combination:
- A combination is a selection of all or part of a set of objects from a larger set such that the order of selection is not important.
- This is given by the formula:
where n is the number of objects in consideration or the larger set from which we have to choose r with no repetition.
