<span>From the pythagorean theorem, we know that x^2 and y^2 = 15^2, where x and y, where x is the base moving from the wall and y is the distance of the ladder sliding down. This means that y = sqrt(225 - x^2). Plugging in x = 13 gives us y = 2sqrt(14). Differentiating both sides of the original equations gives us dy/dt = 13 x 4 / 2sqrt(14) = 52/2sqrt(14) = 26/sqrt(14) ft/s.</span>
Answer:
1) The third option.
2) The last option.
Step-by-step explanation:
1) f(x) is greater on the interval (0,3), which is opened, because if you substitute 
you obtain the following result:
2) If 
, you obtain that:
Therefore: 
P = 4ft
Explanation:
take 5 and 3, add them together = 8. "straight down to double its distance" so that would mean to do either 8 divided by 2 or 4 x 2. 4 x 2 - 3 = 5 (5 = final position). p = 4ft
Answer:
x = 1.33y
Step-by-step explanation:
33% is equal to 0.33. If a number x is 33% more than a number y, then x is 133% of y. 133% = 1.33
Are the 63x and the y being added or multiplied?
