What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

The given expression is

csc² (x) - 2csc(x) cot(x) + cot² (x) = tan² (x/2)

Proceed LHS

csc² (x) - 2csc(x) cot(x) + cot² (x)

⇒ (1/sin²(x) ) - 2(1/sin(x) )(cos(x)/sin(x)) +  (cos(x)/sin(x))²

⇒ (1 - 2cos(x) +  cos(x)²)/sin(x)²

⇒ (1 - 2cos(x) +  cos(x)²)/sin(x)²

⇒ (1 - cos(x))²/sin(x)²

⇒ (1 - cos(x))²/sin(x)²+

⇒ [(1 - cos(x))/sin(x)]²                        [ since tan(x/2) =(1 - cos(x))/sin(x)]

⇒ [ tan(x/2) ]²

⇒ tan²(x/2)   = RHS

Hence proved.

4. On a flight from New York to London, an airplane travels at a constant speed. An equation relating
the distance traveled in miles, d, to number of hours flying, t, is t = 1/350d How long will it take the
airplane to travel 800 miles?

Answers

Answer:

Answer:

1.6 hours or 1 hour 36 minutes

Step-by-step explanation:

We have been given an equation t=\frac{1}{500}dt=

500

1

d , where d represents distance traveled in miles and t represents time in hours.

To find the time taken by the flight to travel 800 miles, we will substitute d=800d=800 in our given equation as:

t=\frac{1}{500}\times 800t=

500

×800

t=\frac{800}{500}t=

500

800

t=\frac{8}{5}t=

t=1.6t=1.6

1 hour equals 60 minutes.

0.6 hours = 0.6*60 minutes = 36 minutes.

Therefore, it will take the plane 1.6 hours or 1 hour 36 minutes to travel 800 miles.

what is the range i need help

Answers

Answer:

[-7, 0]

Step-by-step explanation:

The range describes all values that y can take on. You may notica that the highest point of the graph has an y coordinate of 0 while the lowest has one of -7. Both values are included because they have filled in dots: this means the parenthesis are closed. So, the range would be: [-7, 0]. An alternate way to write this is [tex]-7\leq y \leq 0[/tex].

• (-2, 2)
• (1, 6)
• (4, 5)
• (2, - 2)

Answers

Answer:

(2, -2)

Step-by-step explanation:

Solve 7x - 2y = 18 for x:

[tex]7x - 2y = 18[/tex] [tex]7x - 2y + 2y = 18 + 2y[/tex] (Add 2y to both sides)[tex]7x = 2y + 18[/tex] [tex]\frac{7x}{7} = \frac{2y+18}{7}[/tex] (Divide both sides by 7)[tex]x = \frac{2}{7}y+\frac{18}{7}[/tex]

Substitute 2/7y+ 18/7 for x in -4x + 3y = -14

[tex]-4x + 3y = -14[/tex] [tex]-4(\frac{2}{7}y+\frac{18}{7})+3y=-14[/tex] [tex]\frac{13}{7}y-\frac{72}{7}=-14[/tex] (Simplify both sides of the equation) [tex]\frac{13}{7}y-\frac{72}{7}+\frac{72}{7} =-14+ \frac{72}{7}[/tex] (Add 72/7 to both sides)[tex]\frac{13}{7}y=\frac{-26}{7}[/tex] [tex]\frac{13}{7}y*\frac{7}{13}=\frac{-26}{7} * \frac{7}{13}[/tex] [tex]y = -2[/tex]

Substitute -2 for y in x = 2/7y + 18/7

[tex]x = \frac{2}{7}y + \frac{18}{7}[/tex] [tex]x = \frac{2}{7}(-2) + \frac{18}{7}[/tex] [tex]x = 2[/tex] (Simplify both sides of the equation)

Given that x = 2 and y = -2, the point is: (2, -2)

Therefore, the solution is (2, -2).

2,-2 because X =2 and y=-2 so therefore 2,-2
