For all x,

sin²(x) + cos²(x) = 1

so we have

(1 - cos²A) csc²A = sin²A csc²A

and since csc(x) = 1 / sin(x), so the expression reduces to 1.

Which unit abbreviation is a measurement of force?

Effectus [21]

<h3>Answer: C. N </h3>

N stands for Newtons

In terms of SI units, 1 newton = 1 kg m/s^2

It's based off the equation F = ma, which is Newton's second law.

------------

Extra info:

Choice A is velocity
Choice B is acceleration
Choice D is some unit I don't really recognize, so I'm not sure if its nonsense or it may have some use. Though I'm sure that N/s isn't a measurement of force.

X/(x+5) = (x-2)/(x+1)
x(x+1) = (x -2) (x + 5)
x^2 + x = x^2 - 2x + 5x - 10
x = 3x - 10
3x - x = 10
2x = 10
x = 5

answer is A
5

topjm [15]

Answer:

$257$ adult tickets

Step-by-step explanation:

Let x be the total sold adult ticket.

Given:

Total 582 tickets were sold.

There were 68 fewer student tickets sold than adult tickets

Then there were $x-68$ students.

So, The total sold ticket equation is

$x+(x-68)=582$

$2x-68=582$

$2x=582-68$

$x=\frac{514}{2}$

$x=257$

Therefore, 257 adult tickets were sold
