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
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]

Brainliest are always appreciated :)
Step-by-step explanation:
For Number 1, just make a graph. (THE LINE WILL BE STRAIGHT)
For Number 2:
Proportional is when quantities have the same relative size. In other words they have the same ratio. The cocoa has an equivalent ratio which is why its proportional. This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Given (x+1)2=9, solve for x
Answer:
x= 7/2
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

Cho is making a rectangular garden, where the length is x feet and the width is 2x + 8 feet. He wants to add garden stones around the perimeter of the garden once he is done.
If the garden is 5 feet long, how many feet will Cho need to cover with garden stones?
Cho will need to cover _______ feet with garden stones.
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.

at your house? (Use h for the number of hours).
Answer:
Equation- 50+40h=210
Answer- h=4
Step-by-step explanation:
Just simplify the equation :)
50+40h=210
40h=160
h=4
The electrician worked for 4 hours.

Is it possible to construct a quadrilateral from any 4 given measurements of its sides? State a reason for your answer.
Answer:
It is NOT possible to construct a quadrilateral from any 4 given measurements of its sides.
Step-by-step explanation:
We know that the Quadrilateral is a 2D closed figure with four sides.The Quadrilateral has four vertices or corners.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.

You are going on a trip. To get to the beach, you have to drive 475 miles. If you can average 50 miles per hour on your drive, which equation shows how much farther you have to drive over time?
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
hence the expression
C= -50x+475
Answer:
The answer is in the picture.
p(x)=(1)/(x+1) and q(x)=(1)/(x-1) perform the operation that results in another rational expression p(x)/q(x)
9514 1404 393
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:
(3, 1 )
Step-by-step explanation:
The centre of the circle is at the midpoint of the diameter.
Given endpoint (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (9, 7) and (x₂, y₂ ) = (- 3, - 5 ) , then
midpoint = ( [tex]\frac{9-3}{2}[/tex], [tex]\frac{7-5}{2}[/tex] ) = ( [tex]\frac{6}{2}[/tex], [tex]\frac{2}{2}[/tex] ) = (3, 1 )
Thus centre of circle = (3, 1 )
