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

Answers

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]

Is it possible to construct a quadrilateral from any 4 given measurements of its sides? State a reason for your answer.

Answers

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.

x+1=9/2

x=9/2 - 1

Answer:

x=7/2 x=3.5

Step-by-step explanation:

divide both sides by 2

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

x+1=9/2

subtract 1 from both sides

Jack paid $13.75 to buy 3 slices of pizza and 4 hot dogs at a concession stand. Sarah paid $9.75 to buy 2 slices of pizza and 3 hot dogs from the same concession stand. What is the price of a slice of pizza?

Please help! I will give brainliest to whoever explains how or gets it right

Answers

Answer:
Each slice of pizza costs $2.25

Explanation:
P = prize of a pizza H = price of a hotdog

3p + 4h = $13.75 Multiply this by 2
2p + 3h = $9.75 Multiply this by 3

6p + 8h = $27.50
6p + 9h = $29.25 Subtract

-h = -$1.75 Multiply each side by -1
H = $1.75

A hotdog costs $1.75

2p + 3h = $9.75

2p + 3($1.75) = $9.75
2p + $5.25 = $9.75
2p = $4.50
P = $2.25

How to check:
3p + 4h = 13.75
3($2.25) + 4($1.75) = $13.75
$6.75 + $7.00 = $13.75
$13.75 = $13.75

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.

Answers

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.
