The combinations formula is nCr =
n = complete value set r = desired goal
to find combinations we find all combos for 5,6,7,8,and 9 and add them together.
which come out as 126, 84, 36, 9 and 1
Therefore there are 256 combinations
Answer:
Formula for area is length times width
So 2x × x = 2x^2
E. G.
2×2×2=8
And can also be written as 2^3
Meaning 2×2×2
So in this instance x × x=x^2
In front of the length x imagine a 1
So 2×1=2
Therefore 2x^2
From the figure, we immediately have
cos(θ) = 8/17
sin(θ) = 15/17
By definition of tangent,
tan(2θ) = sin(2θ)/cos(2θ)
Recall the double angle identities:
sin(2θ) = 2 sin(θ) cos(θ)
cos(2θ) = cos²(θ) - sin²(θ) = 2 cos²(θ) - 1
Then
tan(2θ) = (2 sin(θ) cos(θ)) / (2 cos²(θ) - 1)
tan(2θ) = (2 × 15/17 × 8/17) / (2 × (8/17)² - 1)
tan(2θ) = -240/161
Answer:
7
Step-by-step explanation:
total book =1
1/5 + 2/3 + wed = 1
get a common denominator of 15
1/5 * 3/3 + 2/3 * 5/5 + wed = 1 * 15/15
3/15 + 10/15 + wed = 15/15
combine like terms
13/15 + wed = 15/15
subtract 13/15 on each side
wed = 15/15-13/15
wed = 2/15
He read 2/15 of the book on Wednesday
