Answer: ∠ORP and ∠ORN are a linear pair

Step-by-step explanation:

A linear pair is when two adjacent angles create a straight line, which adds up to 180°. Both ∠ORP and ∠ORN are adjacent and form a straight line, so they would be considered a linear pair.

Answer:

D

Step-by-step explanation:

y = 15 so 2/3 times 15 equals 30/3, which equals to 10

so far, you have 1/5 - 10 = 30

10 plus 30 equals to 40 so basically you have to find what times 1/5 equals to 40

200 times 1/5 is 40

sorry if this is too hard to understand but I tried my best to make it sound easy

The interest with the given principal, time period and rate of interest is $3076.

Given that, principal=$50,000, time period =6 years and rate of interest =1%.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest is

Amount =Principal(1+r/100)^t

= 50000(1+1/100)^6

= 50000(1.01)^6

= 53076

So, interest =Amount-Principal

= $3076

Therefore, the interest with the given principal, time period and rate of interest is $3076.

Step-by-step explanation:

The slopes of the two lines are 3, 3.

The slope of AB is 3.

The slope of a line passing through points [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] is

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Given two points are [tex]A(-1, -4)[/tex] and [tex]B(2, 5)[/tex].

Therefore, the slope of a line passing through those two points is

[tex]m_{1} = \frac{5 - (-4)}{2-(-1)}[/tex]

⇒ [tex]m_{1} = \frac{9}{3}[/tex]

⇒ [tex]m_{1} = 3[/tex]

Another two points are [tex]C(3, -7)[/tex] and [tex]D(5, -1)[/tex].

[tex]m_{2} = \frac{-1 - (-7)}{5-3}[/tex]

⇒   [tex]m_{2} = \frac{6}{2}[/tex]

⇒   [tex]m_{2} = 3[/tex]

Answer:

6[tex]\frac{3}{4}[/tex]

Step-by-step explanation:

First, we can start by figuring out how many nails can be produced by 1 machine in 15 minutes. Since 3 machines can produce 16 [tex]\frac{1}{5}[/tex] nails per 15 minutes, we can figure this out by dividing the number of nails produced by 3.

16 [tex]\frac{1}{5}[/tex] divided by 3 equals [tex]\frac{81}{48}[/tex] which can be simplified to 1 [tex]\frac{11}{16}[/tex]. This means that in 15 minutes, one machine can produce 1 [tex]\frac{11}{16}[/tex] nails. Since 15 minutes is 1/4 of an hour, we multiply the nails and minutes by 4, and  1[tex]\frac{11}{16}[/tex] times 4 equals 6[tex]\frac{3}{4}[/tex]. Therefore, 1 machine can produce 6[tex]\frac{3}{4}[/tex] nails in one hour.

Answer:

Absolute value means how far are you from zero on the number line.

absolute value of | -18| for example is 18  

this means that you are at -18 on the number line that is 18 points away from zero.

and absolute value of |18 | is 18

this means that you are at point 18 on the positive direction on the number line. That is 18 points away from zero.

Equation at the end of step 1

STEP

:

           x3 - 2x2 + 2x - 1

Simplify   —————————————————

                 x - 1      

Checking for a perfect cube :

2.1    x3 - 2x2 + 2x - 1  is not a perfect cube

Trying to factor by pulling out :

2.2      Factoring:  x3 - 2x2 + 2x - 1  

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  2x - 1  

Group 2:  -2x2 + x3  

Pull out from each group separately :

Group 1:   (2x - 1) • (1)

Group 2:   (x - 2) • (x2)

Bad news !! Factoring by pulling out fails :

The groups have no common factor and can not be added up to form a multiplication.

Polynomial Roots Calculator :

2.3    Find roots (zeroes) of :       F(x) = x3 - 2x2 + 2x - 1

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  1  and the Trailing Constant is  -1.

The factor(s) are:

of the Leading Coefficient :  1

of the Trailing Constant :  1

Let us test ....

  P    Q    P/Q    F(P/Q)     Divisor

     -1       1        -1.00        -6.00      

     1       1        1.00        0.00      x - 1  

The Factor Theorem states that if P/Q is root of a polynomial then this polynomial can be divided by q*x-p Note that q and p originate from P/Q reduced to its lowest terms

In our case this means that

  x3 - 2x2 + 2x - 1  

can be divided with  x - 1  

Polynomial Long Division :

2.4    Polynomial Long Division

Dividing :  x3 - 2x2 + 2x - 1  

                             ("Dividend")

By         :    x - 1    ("Divisor")

dividend     x3  -  2x2  +  2x  -  1  

- divisor  * x2     x3  -  x2          

remainder      -  x2  +  2x  -  1  

- divisor  * -x1      -  x2  +  x      

remainder             x  -  1  

- divisor  * x0             x  -  1  

remainder                0

Quotient :  x2-x+1  Remainder:  0  

Trying to factor by splitting the middle term

2.5     Factoring  x2-x+1  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -x  its coefficient is  -1 .

The last term, "the constant", is  +1  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 1 = 1  

Step-2 : Find two factors of  1  whose sum equals the coefficient of the middle term, which is   -1 .

     -1    +    -1    =    -2  

     1    +    1    =    2  

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Canceling Out :

2.6    Cancel out  (x-1)  which appears on both sides of the fraction line.

Final result :

 x2 - x + 1
