Question #2 What is the difference?​

Mathematics

e-lub [12.9K]3 years ago
3 0

Answer:

B  \frac{b-10}{b-1}

Step-by-step explanation:

In order to get the same denominator, we need to multiply the second fraction by (b+2) in the numerator and denominator.

We will end up in something like this :\frac{b^{2} - 2b - 8 -6(b+2) }{(b-1)(b+2)}

I just timed the second fraction by b+ 2 and then i added them together.

Therefore, we will get \frac{b^{2} - 8b - 20}{(b-1)(b-2)}

now factoring the numerator we will end like this

\frac{(b-10)(b+2)}{(b-1)(b+2)}

we will then end up with the answer.

Hope this helps.

The mean is  6394530.35 and the median is = 3355572.5

The missing data is attached in the answer.

<h3>What is Mean ?</h3>

Mean is the average value of the data points , it is determined by dividing the total sum of the data points to the number of data points.

Mean and Median is the measure of the central; tendency of the data.

Mean is given by

Sum of the observations/number of observations

= (741894 + 6931071....)/20

= 6394530.35

2) To find median

The data needs to be arranged in ascending order

Then the median is the middle number of the arranged data

Here the median is = 3355572.5

What is the vertex of the function?
egoroff_w [7]
<h2>Explanation:</h2><h2></h2>

Here you haven't provided any function, so I'll assume this one:

f(x)=3x^2-18x+33

This is a quadratic function whose graph represents a parabola. Any parabola has its vertex at the point:

V(x,y) \\ \\ \\ x=-\frac{b}{2a} \\ \\ y=f(-\frac{b}{2a}) \\ \\ \\ where: \\ \\ \\ f(x)=ax^2+bx+c \\ \\ \\ So: \\ \\ a=3 \\ \\ b=-18 \\ \\ c=33

Therefore:

x=-\frac{(-18)}{2(3)}=3 \\ \\ f(3)=3(3)^2-18(3)+33=27-54+33=6

Therefore, the vertex is:

\boxed{V(3,6)}

Easy
remember
x^-m=1/(x^m)

so

f(-1)=4*7^-1=4*(1/(7^1))=4*(1/7)=4/7
f(2)=4*7^2=4*49=196
