F + 2/9 = 9 * 9 + 1/9
f + 2/9 = 81 + 1/9
f + 2/9 = 82/9
f = 82/9 - 2/9
f = 80/9
Since the answer choices seem to be mixed fractions, lets make 80/9 into one of them to get our answer.
9 divided by 80
9 divided by 80 is 8 with a remainder of 8
Now lets make it a mixed fraction
8 8/9
Answer: A)
Part A. You have the correct first and second derivative.
---------------------------------------------------------------------
Part B. You'll need to be more specific. What I would do is show how the quantity (-2x+1)^4 is always nonnegative. This is because x^4 = (x^2)^2 is always nonnegative. So (-2x+1)^4 >= 0. The coefficient -10a is either positive or negative depending on the value of 'a'. If a > 0, then -10a is negative. Making h ' (x) negative. So in this case, h(x) is monotonically decreasing always. On the flip side, if a < 0, then h ' (x) is monotonically increasing as h ' (x) is positive.
-------------------------------------------------------------
Part C. What this is saying is basically "if we change 'a' and/or 'b', then the extrema will NOT change". So is that the case? Let's find out
To find the relative extrema, aka local extrema, we plug in h ' (x) = 0
h ' (x) = -10a(-2x+1)^4
0 = -10a(-2x+1)^4
so either
-10a = 0 or (-2x+1)^4 = 0
The first part is all we care about. Solving for 'a' gets us a = 0.
But there's a problem. It's clearly stated that 'a' is nonzero. So in any other case, the value of 'a' doesn't lead to altering the path in terms of finding the extrema. We'll focus on solving (-2x+1)^4 = 0 for x. Also, the parameter b is nowhere to be found in h ' (x) so that's out as well.
Answer:
32.54%
Step-by-step explanation:
To determine the probability that an individual song has a danceability of at least 0.7
Applying the excel formula below
=COUNTIF ( I2:I4771,">0.7") / ROWS( I2:I4771)
Hence ; The probability of an individual song having a danceability of at least 0.7 = 32,54%
Answer:
Slope: 1
Y-intercept: (0,3)
Step-by-step explanation:
The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.
Y intercept: (0, 3)
For slope, you can use the formula rise over run. 
From the picture, I have drawn the rise over run, which is 
, which is also 1.
Slope: 1
Hope this helped.
