Answer:
A.
Step-by-step explanation:
We are given the functions f(x) and g(x) as,
It is required to find the function ( f+g ) i.e. ( f+g ) (x)
So,
i.e.
Hence, we get that .
So, the first option is correct.
Answer:
Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951
Step-by-step explanation:
The fraction of older Americans who were included in the study and suffered broken bones during the three-year period?
This fraction = (Number of older Americans who suffered broken bones recorded during the three year period of the study)/(Total number of older Americans involved in the study)
Number of older Americans who suffered broken bones recorded during the three year period of the study = (11 from those that took the additional supplements) + (26 from those that did not take additional supplements) = 11 + 26 = 37
Total number of older Americans involved in the study = 389
Fraction of older Americans who were included in the study and suffered broken bones during the three-year period = (37/389) = 0.0951
Answer:
Step-by-step explanation:
x + 6 I x³ + 2x² - 10x + 84 I x² - 4x + 14
x³ + 6x²
<u> - - </u>
-4x² - 10x
-4x² - 24x
<u> + + </u>
14x + 84
14x + 84
<u> - - </u>
0
P(x) =(x +6)* ( x² - 4x + 14) + 0
Answer:
Calculate distance first - so using the image we know that if we use pythogorean theorm we can get 2 vectors of this line, 1 completely vertical and one completely horizontal. Apply pythogorean theorm to the line and use for all other question. So 6^2+2^2=c^2
36+4=c^2
distance √40 half of it is √10
So we can use for this for it. (4-√10, 0-√10) so its (4-√10, -√10) for first one
Now that we dont have the image for the line we can apply the distance formula because we dont have clear view of points for #2. -2-6 = -8 then we need 5-1 = 4, -8^2+4^2 = c^2 so then sqrt(80) is distance. 2√5 is half. So then we subtract from (-5, 2) highest point on graph.( -5-√20, 2-√20).
Since this is heavily on writing I expect you to do the rest. Calculating the distance and pythogorean theorm on your own.
First 2 answers are
<u> (4-√10, -√10)</u>
<u></u>
<u>( -5-√20, 2-√20)</u>
If 2 plus 2 is four... then what the hell is this?
