If f has a local maximum value at x = a, what would you expect the graph of f ' to look like near x = a?

1 answer:

5 0

You would expect $f$ to be increasing to the left of $x=a$ , and decreasing to the right, which corresponds to $f'$ being positive when $x$ (but near $x=a$ ) and negative when $x>a$ .

What is the value of x? Enter your answer, as a decimal, in the box. cm

Answer:

50.6 cm

Step-by-step explanation:

We can use similar triangles and proportions to solve. Put the smaller triangle side over the larger triangle side.

x 46.2-14 (This is the length of the short side of the triangle)

--------- = -------------

72.6 46.2

Using cross products

46.2 *x = (46.2-14) *72.6

46.2 *x = (32.2) *72.6

46.2x =2337.72

Divide each side by 46.2

46.2/46.2 *x = 2337.72/46.2

x = 50.6

Mazyrski [523]

Answer:

Dan is correct

Step-by-step explanation:

From the question, we have:

$Hours:1\ 2\ 3\ 4\ 5$

Required

The average

The average hour is calculated using:

$\bar x = \frac{\sum x}{n}$

So, we have:

$\bar x = \frac{1+2+3+4+5}{5}$

$\bar x = \frac{15}{5}$

$\bar x = 3$

Dan calculated the mean as 3; while Bret calculated the mean as 4.

Hence, we can conclude that Dan s correct

Someone solve this for me please

Butoxors [25]

Answer:

x=2; y=1

Step-by-step explanation:

Since the triangle is equilateral, which means three sides have the same length.

So we have：4x-y=2x+3y=7

$4x-y=2x+3y\\4x-y+y=2x+3y+y\\4x=2x+4y\\2x=4y\\x=2y\\$

Since 2x+3y=7 and plug in x=2y

we have

$2x+3y=7\\2(2y)+3y=7\\4y+3y=7\\7y=7\\y=1$

and since y=1

x=2
