Step-by-step explanation:

Well you have the right girl! *In honors geometry you can trust me!

Ok first thing...We already know

B = 54

A = 90  

D = 54 (It's the Alternate interior angle of B)

C = 90

m<ACD = 90 (C = 90)

m<CDB = 126 (D = 54 ------> 180-54= 126)

m<EDB = 54 (Alternate Interior angle of B)

m<CDE = 180 (It is a straight line)

a. y=5x/x*x^2

b. y=5x/1+2x^2

c. y=5x-1/x

d. y=x/1-x^2

Answers

Answer:

B. y=(5x)/(1 + 2x^2)

Step-by-step explanation:

A. y = (5x)/(x * x^2)

Vertical Asymptotes: x = 0

B. y = (5x)/(1 + 2x^2)

Vertical Asymptotes: None

Answers

Answer:

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Step-by-step explanation:

Given the function

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]

As the highest power of the x-variable is 3 with the leading coefficients of 1.

So, it is clear that the polynomial function of the least degree has the real coefficients and the leading coefficients of 1.

solving to get the zeros

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex]

[tex]0=x^3-6x^2+3x+10[/tex]              ∵  [tex]f(x)=0[/tex]

as

[tex]Factor\:x^3-6x^2+3x+10\::\:\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]

so

[tex]\left(x+1\right)\left(x-2\right)\left(x-5\right)=0[/tex]    

Using the zero factor principle

if  [tex]ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]

[tex]x+1=0\quad \mathrm{or}\quad \:x-2=0\quad \mathrm{or}\quad \:x-5=0[/tex]

[tex]x=-1,\:x=2,\:x=5[/tex]

Therefore, the zeros of the function are:

[tex]x=-1,\:x=2,\:x=5[/tex]

[tex]f\left(x\right)=x^3-6x^2+3x+10[/tex] is the function of the least degree has the real coefficients and the leading coefficients of 1 and with the zeros -1, 5, and 2.

Therefore, the last option is true.

The top view of a school bus showing the arrangement of the passenger seats is shown below: which of the following is the correct way of counting the total number of passenger seats in the bus

Answers

The correct way of counting the total number of passenger seats in this bus is: option C: 5 × 12 + 6.

What is an expression?

An expression refers to a mathematical equation which is used to show the relationship that exist between two or more numerical quantities.

How to calculate the total number of passenger seats?

In order to determine the total number of passenger seats, we would develop an expression that multiplies the rows by the columns and then add the remaining seats as follows:

Total number = (5 × 12) + 6

Total number = 60 + 6

Total number = 66 seats.
