The formula to find the volume of a pyramid is: V=lwh/3 therefore:
V = lwh/3
38 = 6(6)(h)/3
114 = 36(h)
h = 3.17 (2 dec. places)
The height of the square pyramid is 3.17cm.
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.
Answer:

Step-by-step explanation:
Given
Required
Complete the squares
We have:
---------------------------------------------
Take the coefficient of -6 i.e. -3
Square it (-3)^2 = 9
Add 9 to both sides
---------------------------------------------
<em>Hence, C is correct</em>
