Answer:

Probability of drawing non defective bulb

=90/100×89/99×88/98×...........×82/92..........(i)=90/100×89/99×88/98×...........×82/92..........(i)

Now the probability of drawing at least one bulb will be defective

=1−(i)=1−90/100×89/99×88/98×...........×82/92

1−(90/100⋅89/99⋅…⋅83/93)

what do you think would happen to a person if mortor neuron from the grey matter of spinal cord is removed?​
ziro4ka [17]

Step-by-step explanation:

Introduction

Until World War II, a serious spinal cord injury (SCI) usually meant certain death. Anyone who survived such injury relied on a wheelchair for mobility in a world with few accommodations and faced an ongoing struggle to survive secondary complications such as breathing problems, blood clots, kidney failure, and pressure sores. By the middle of the twentieth century, new antibiotics and novel approaches to preventing and treating bed sores and urinary tract infections revolutionized care after spinal cord injury. This greatly expanded life expectancy and required new strategies to maintain the health of people living with chronic paralysis. New standards of care for treating spinal cord injuries were established: reposition the spine, fix the bones in place to prevent further damage, and rehabilitate disabilities with exercise.

Today, improved emergency care for people with spinal cord injuries, antibiotics to treat infections, and aggressive rehabilitation can minimize damage to the nervous system and restore function to varying degrees. Advances in research are giving doctors and people living with SCI hope that spinal cord injuries will eventually be repairable. With new surgical techniques and developments in spinal nerve regeneration, cell replacement, neuroprotection, and neurorehabilitation, the future for spinal cord injury survivors looks brighter than ever.

A hair salon charges a fixed rate of $25.00 for a haircut and then an additional $15 for any other services. Write a function to
DIA [1.3K]

Answer:

A)  f(x) = 15x + 25; f(0) = 25

Step-by-step explanation:

x represents the amount of extra services, and 15x respresents the amount paid for all of the services. 25 represents the initial fee. f(0)=25 means that it cost $25 for a haircut with no extra services.

Let's say you have a haircut with two extra services. You would replace the x in the equation with the number of extra services, 2 in this case.

f(2)=15(2) + 25

f(2)=30+25

f(2)=55

It would cost $55 for a haircut with 2 extra services.

Part (a)

The domain is the set of allowed x inputs of a function.

The graph shows that x = 0 is not allowed because of the vertical asymptote located here. It seems like any other x value is fine though.

<h3>Domain: set of all real numbers but x \ne 0</h3>

To write this in interval notation, we can say (-\infty, 0) \cup (0, \infty) which is the result of poking a hole at 0 on the real number line.

--------------

The range deals with the y values. The graph makes it seem like it stretches on forever in both up and down directions. If this is the case, then the range is the set of all real numbers.

<h3>Range: Set of all real numbers</h3>

In interval notation, we would say (-\infty, \infty) which is almost identical to the interval notation of the domain, except this time of course we aren't poking at hole at 0.

=======================================================

Part (b)

<h3>The x intercepts are x = -4 and x = 4</h3>

We can compact that to the notation x = \pm 4

These are the locations where the blue hyperbolic curve crosses the x axis.

=======================================================

Part (c)

<h3>Answer: There aren't any horizontal asymptotes in this graph.</h3>

Reason: The presence of an oblique asymptote cancels out any potential for a horizontal asymptote.

=======================================================

Part (d)

The vertical asymptote is located at x = 0, so the equation of the vertical asymptote is naturally x = 0. Every point on the vertical dashed line has an x coordinate of zero. The y coordinate can be anything you want.

<h3>Answer: x = 0 is the vertical asymptote</h3>

=======================================================

Part (e)

The oblique or slant asymptote is the diagonal dashed line.

It goes through (0,0) and (2,6)

The equation of the line through those points is y = 3x

If you were to zoom out on the graph (if possible), then you should notice the branches of the hyperbola stretch forever upward but they slowly should approach the "fencing" that is y = 3x. The same goes for the vertical asymptote as well of course.

<h3>Answer:  Oblique asymptote is y = 3x</h3>

What is the range and domain of the relation?<br><br> {(-3, 4), (-2, 0), (0, -1), (1, 2), (-3, 2)}?​
Rus_ich [418]

Answer:

Range: {-1, 0, 2, 4}

Domain: {-3, -2, 0, 1}

Step-by-step explanation:

The range is the set containing all y-coordinates.

The domain is the set containing all x-coordinates.

A coordinate appears only once in each set.

Range: {-1, 0, 2, 4}

Domain: {-3, -2, 0, 1}
