Answer:

d. $6,000

Step-by-step explanation:

We have been given that the office manager of First Tech Support borrowed $25,000 to purchase new computers for employees. The bank charges 6 percent interest for 4 years.

We will use simple interest formula to solve our given problem.

I=Prt, where,

I - Amount of interest,

P = Principal amount,

r = Interest rate in decimal form,

t = Time in years.

First of all, we will convert our given interest rate in decimal form.

6\%=\frac{6}{100}=0.06

Upon substituting our given values in simple interest formula, we will get

I=\$25,000*0.06*4

I=\$6,000

Therefore, the company will pay an amount of $6,000 in interest and option 'd' is the correct choice.

The answer is $6,000, because you multiply the 25,000 times .6 percent for interest, then multiply $15000 times .4 years and $6000 will be what you pay in interest.

Step-by-step explanation:

according to pythagoras theorem

Hypotenuse2 = Perpendicular2 + Base2

c2 = a2 + b2

therefore,

x2 = (4)2 + (4)2

x2 = 16 + 16

x2 = 32

x = √32

hence, x = 4√2

Find the value of the third quartile (the median of the upper half of the data set). 52, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61,
serious [3.7K]

Answer:

64.5

Step-by-step explanation:

You understand the question, and already have the numbers in order, you're almost there!

So you need to find the median first so you can divide the data set into the upper and lower halves. The median, as you probably know, is the center of the data. What I do for this is list all the numbers out in order, like you've already done, and start crossing them out, one at a time, alternating the sides. I'll show you what I mean. (I'm using underline because there's no strikethrough.)

<u>52</u>, 54, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, 70, <u>72</u>

<u>52, 54</u>, 55, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, 68, <u>70, 72</u>

<u>52, 54, 55</u>, 55, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, 65, <u>68, 70, 72</u>

<u>52, 54, 55, 55</u>, 57, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, 65, <u>65, 68, 70, 72</u>

<u>52, 54, 55, 55, 57</u>, 58, 59, 59, 61, 61, 61, 62, 63, 63, 64, <u>65, 65, 68, 70, 72</u>

...and so on, until you have:

<u>52, 54, 55, 55, 57, 58, 59, 59, 61</u>, 61, 61, <u>62, 63, 63, 64, 65, 65, 68, 70, 72</u>

Because there's an even number of numbers, the median is the mean of the middle two numbers. Luckily, though, the two numbers in the middle are the same:61. Mean is calculated by adding the terms and dividing by the number of terms. In this case:

(61+61)/2

=61

(You didn't really have to do this mean step, but I'll explain later.)The median is 61. Another way you could have done this is by just counting the number of terms (20) and finding the middle one. Again, since there's no middle one, you'd have to find the mean.

Since you're looking for the third quartile and not the median, you didn't exactly have to do that step. I just wanted to explain how to calculate the median, since you'll have to do it in the next step. All we had to do here was divide the data set into the halves, so we used that visual demonstration by underlining the numbers one at a time. We didn't have to find the mean, we could have split the set down the middle instead.

<u>52, 54, 55, 55, 57, 58, 59, 59, 61, </u>61, | 61, <u>62, 63, 63, 64, 65, 65, 68, 70, 72</u>

                                                             ^median/half-way point

We could have also divided the number of terms (20) by 2 (because halves, 2 parts) to get 10 and used the upper 10 values of the set, but I don't know, the crossing out method helps me. Anyway, now we have to look at just the upper 10 values:

61, 62, 63, 63, 64, 65, 65, 68, 70, 72

And you repeat the process! (I'm not going to show the underlining though lol)

There are 10 terms, so the median is between the 5th and the 6th. (10/2=5)

<u>61, 62, 63, 63</u>, 64, 65, <u>65, 68, 70, 72</u>

This is what I was talking about, there are an even number of values in the upper half of the data set as well, so we have to find the mean of the middle 2: 64 and 65.

 (64+65)/2

=129/2

=64.5

That's your final answer. Hope I could help you!

Write a rational function with the given characteristics.
Maurinko [17]

According to the question, to express the rational function for the vertical asymptote whose equation is x=8 and horizontal asymptote whose equation is at y=0.

As per the question, the function 'f(x)' is vertical at x=8. Therefore, the denominator be (x-8)

f(x)=\frac{g(x)}{(x-8)}

The function 'g(x)' should have same degree as the denominator function has and it is defined asy=0

The rational function can be written as:

Rational function = \frac{y}{(X-8)}

What is rational function?

Rational function is a function whose numerator and denominator terms are in polynomials. Basically, it is a ratio of polynomials. The important condition for these type of function is that denominator should be of degree one.
