Exact form is 8/7 , as a decimal its 1.142 and mixed number form its 1 1/7
Answer:
21.9%
Step-by-step explanation:
7000000/32000000=0.21875
move the decimal over two places to get percent and round the 8 up because of the 7. 21.9%
Answer:
tan M = 
Step-by-step explanation:
To obtain tan M we require to find KL
Using Pythagoras' identity in the right triangle.
KL² + LM² = KM²
KL² + 7² = 25²
KL² + 49 = 625 ( subtract 49 from both sides )
KL² = 576 ( take square root of both sides )
KL = 
= 24
Then
tan M = 
= 
=
Choice A) The vertical line test confirms that the graph is a function
True. It is impossible to pass a single vertical line through more than one point on this graph.
--------------------------------------------
Choice B) The domain is x >= 2
False. The domain is the set of all real numbers
--------------------------------------------
Choice C) The range is y >= 2
True. The smallest y value possible is y = 2. This is where the lowest part of the graph occurs.
--------------------------------------------
Choice D) This piecewise function is made up of four intervals
False. There are two intervals (the curved one on the left; the straight piece on the right)
--------------------------------------------
Choice E) Each interval of the piecewise function contains a graph of a linear function.
False. While the piece on the right is linear, the left portion is nonlinear (curved piece).
--------------------------------------------
In summary we have:
choice A) true
choice B) false
choice C) true
choice D) false
choice E) false
So the answers are choice A and choice C
Answer:
Step-by-step explanation:
Given 3x-4y=65
Y=4
So 3x-4×4=65
3x-16=65
3x=65+16
X=81/3
X=27
So value of X is 27
