2.6, 2.7, 2.8,2.9. All of these numbers are between 2.5 and 3.0
1) sin(90 - A) = cos A=√(2/3) or √6/3
2) sin²A + cos²A=1
sin²A= 1 -cos²A=1 - (√2/3)²= 1 - 2/3= 1/3
sin A = 1/√3 or √3/3
3) tan A= sin A/ cos A= (1/√3)/(√2/√3)= 1/√2
tan A = 1/√2 or √2/2
Answer:
What happens when h is positive?
The asymptote of the graph shifts <em>right</em> by that amount.
What happens when h is negative?
The asymptote of the graph shifts <em>left</em> by that amount.
What happens when k is positive?
The entire graph shifts <em>up</em> by that amount.
What happens when k is negative?
The entire graph shifts <em>down</em> by that amount.
<span>A rope weighs 400 grams per meter of length.
length=6.3m
400*6.3=2520g
2520g=2520/1000kg=2.52kg
The answer is D.</span>
The answer is:
Square root of 77
—————————
22
You need to rationalize the denominator meaning that you have to get rid of the square root signs in denominator
To get rationalize the denominator you need to multiply both sides by square root of 11
(Square root of 7)(square root of 11)
——————————————————
2(square root of 11)^2
When squaring a square root it makes the square root “go away”
(Square root of 77)
——————————
2(square root of 11^2 or 122) = 2(11)
So:
The answer is
square root of 77
—————————
22
