Answer:
None of these statements are true.
Step-by-step explanation:
a) The derivative of (fg)(x) is f'g +fg' according to the product rule for derivatives.
__
b) The derivative of |x² +x| is a 3-part piecewise linear function equal to 2x+1 for |x+1/2| > 1/2, and equal to -2x-1 for |x+1/2| < 1/2. It is undefined for x=0 and x=1.
__
c) for y = √f(x), y' = f'(x)/(2√f(x))
The phytagorean theorem states a^2 + b^2 = c^2
And so your answer is C. (UV)^2+(VW)^2=(UW)^2, because 81+144=225
Since they are squares, the length of one sides square is equal to the area. UV, VW, and UW are all sides on a square. If you square them, you get their area, and then if you add the areas it will prove the phytagorean theorem correct.
Answer:
Step-by-step explanation:
Let
y -----> the profit earned by the hot dog stand daily
x ----> the number of hot dogs sold
we know that
The linear equation that represent this problem is equal to
This is the equation of the line into slope intercept form
where
----> is the slope
---> is the y-intercept (cost of the day's supply)
Answer:
y = 15x
Step-by-step explanation:
For every hour that has gone by, Marco biked 15 miles, therefore, the equation of the line that shows the relationship between the time, x, and the distance, y, is <em>y = 15x</em>.
