Answer:
180 fb*lb
45 ft*lb
Step-by-step explanation:
We have that the work is equal to:
W = F * d
but when the force is constant and in this case, it is changing.
therefore it would be:
Where a = 0 and b = 30.
F (x) = 0.4 * x
Therefore, we replace and we would be left with:
We integrate and we have:
W = 0.4 / 2 * x ^ 2
W = 0.2 * (x ^ 2) from 0 to 30, we replace:
W = 0.2 * (30 ^ 2) - 0.2 * (0 ^ 2)
W = 180 ft * lb
Now in the second part it is the same, but the integral would be from 0 to 15.
we replace:
W = 0.2 * (15 ^ 2) - 0.2 * (0 ^ 2)
W = 45 ft * lb
Step-by-step explanation:
Given that the set of data collected has an extreme value (24), a Median measure of center is more appropriate than a Mean measure.
We sort the same data collected in increasing order:
{0, 1, 2, 4, 4, 5, 5, 24}
There are 8 elements inside the set, so we check the 4th and 5th elements (closest to the center), which are 4 and 4.
Since they are equal, the Median is 4.
Our answer is Median; 4.
Answer:
5
-- chance
9
you gotta count up all the possibilies (which is 9) then count up all the possible chances there is a rock (which is 5) and put it into fraction form. and there's your probability
Sorry this took awhile.
So for Friday, it would be $550
Saturday, $895
Sunday, 1,095
So the total is $2540 if you add the numbers up. Hope this helps!
Answer: 11 degrees
Step-by-step explanation:
Complementary means 2 angles that add up to 90 degrees.
90 degrees - 79 degrees = 11 degrees
Double Check: 79+11 = 90 degrees
