Answer:

  p(x)/q(x) = (x -1)/(x +1)

Step-by-step explanation:

  [tex]p(x)\div q(x)=\dfrac{1}{x+1}\div\dfrac{1}{x-1}=\dfrac{1}{x+1}\times\dfrac{x-1}{1}\\\\ \boxed{\dfrac{p(x)}{q(x)}=\dfrac{x-1}{x+1}}[/tex]

Answer:

38 feet

Step-by-step explanation:

P(x) = ℓ(x) + ℓ(x) + w(x) + w(x)

      = x + x + (4x - 1) + (4x - 1)

      = (x + x + 4x + 4x) + (-1 -1)

      = 10x - 2

P(4) = 10(4) -2 = 38

The perimeter is 38 feet when the length is 4 feet long, so Cho will need to

cover 38 feet with garden stones.

Answer: $1,266.697.

Step-by-step explanation:

given data:

loan amount =  $7500

duration = 6 months

interest rate = 2.5%

Solution:

[tex]A = P \frac{i(1+i)^{n} }{(1+i)^{n} -1}[/tex]

i = [tex]\frac{2.5}{100} \\= 0.025\\\frac{0.025}{6} \\= 0.004167[/tex]

=

= [tex]7500(\frac{0.00427}{0.0253} )[/tex]

= [tex]7500(0.169)[/tex]

= $1,266.697

Answer:

C

Explanation:

A function always goes along the x-axis and never repeats

A, B and D repeat on the x-axis so C is your answer

Answer:

?

Step-by-step explanation:

When you raise a number to a negative exponent, change the exponent to a positive and make the complete number a fraction with 1 as the numerator.

5 ^-2 = 1/5^2

The answer is C.

Answer:

The answer is below

Step-by-step explanation:

We need to prove that:

(Root of Sec A - 1 / Root of Sec A + 1) + (Root of Sec A + 1 / Root of Sec A - 1) = 2 cosec A.

Firstly, 1 / cos A = sec A, 1 / sin A = cosec A and tanA = sinA / cosA.

Also, 1 + tan²A = sec²A; sec²A - 1 = tan²A

[tex]\frac{\sqrt{secA-1} }{\sqrt{secA+1} } +\frac{\sqrt{secA+1} }{\sqrt{secA-1} } =\frac{(\sqrt{secA-1)}(\sqrt{secA-1})+(\sqrt{secA+1)}(\sqrt{secA+1}) }{(\sqrt{secA+1})(\sqrt{secA-1}) } \\\\=\frac{secA-1+(secA+1)}{\sqrt{sec^2A-secA+secA-1} } \\\\=\frac{2secA}{\sqrt{sec^2A-1} } \\\\=\frac{2secA}{\sqrt{tan^2A} } \\\\=\frac{2secA}{tanA} \\\\=\frac{2*\frac{1}{cosA} }{\frac{sinA}{cosA} }\\\\= 2*\frac{1}{cosA}*\frac{cosA}{sinA}\\\\=2*\frac{1}{sinAA}\\\\=2cosecA[/tex]

Answer:

28 / 7 /4 = 1

Step-by-step explanation:

Division Signs to make the correct equality are 2 8/ 7 / 4 = 1

In mathematics, the equal sign denotes parity between quantities, equations, or expressions written on either side. Equal to is represented by two thin, parallel horizontal lines. The "equal to" sign is used to indicate that two items are the same or equal. For instance, 1 + 1 = 2.

A division sign exists the symbol ÷ used between two numerals to demonstrate that the first number maintains to be divided by the second.

Given,

a = 28/7 = 4

b = 4/4 = 1

Answer:

C= -50x+475

Step-by-step explanation:

Step one:

given data

distance travelled = 475miles

velocity = 50miles per hour

let the distance you cover per hour be x

hence per hour, your distance decreases by 50x hours

Required:

The expression for the distance remaining

Step two:

let the distance remaining be C

2(x+1)=9

x+1=9/2

x=9/2 - 1

x=7/2

Answer:

x=7/2 x=3.5

Step-by-step explanation:

divide both sides by 2

(x+1)(2)/2=9/2

simplify

x+1=9/2

subtract 1 from both sides

x+1-1=9/2-1

simplify

x=7/2

It is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.

Step-by-step explanation:

We are asked to tell whether it is possible to construct a quadrilateral from any 4 given measurements of its sides.

Well, in order to construct a quadrilateral from any 4 given measurements of its sides, we need at least five dimensions.

With only 4 given measurements of its sides, we won't know any of its angles.

Thus, it is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.
