Mathematics
1 answer:
abruzzese [7]3 years ago
4 0

Answer:

400

Step-by-step explanation:

You know that 80 is 20% of whatever number you are trying to get, and you want 100% of that number, so times 80 by 5 (20% times 5) to get your number.

If we take the Pythagorean identity identity sin^2 x + cos^2 x = 1 then
                          <span>(cos^2 x + sin^2 x) / (cot^2 x - csc^2 x)
The numerator becomes 1 since addition order matters not.
                                                 1 / </span>(cot^2 x - csc^2 x)
If we factor the denominator out a negative
                                                1 / -(<span>csc^2 x - cot^2 x)
Consider </span><span>sin^2 x + cos^2 x = 1. Divide both sides by sin^2 x to get
                                         1 + cot^2 x = csc^2 x
Subtract both sides by cot^2 x to get 1 = csc^2 x - cot^2 x.
Replace the denominator
                                                 1 / -(1) = -1
For cos</span>^2 θ / sin^2 θ + csc θ sin θ, we use cscθ = 1/sinθ and cosθ/sinθ = cotθ so
                                = cos^2 θ / sin^2 θ + 1
                                = cot^2 θ + 1
We use 1 + cot^2 <span>θ = csc^2 </span>θ to simplify this to
                              = csc^2 θ

Answers:         -1
                          csc^2 θ

X, y - the numbers

xy=24 \\&#10;x+y=25 \\ \\&#10;\hbox{solve the second equation for y:} \\&#10;x+y=25 \\&#10;y=25-x \\ \\&#10;\hbox{substitute 25-x for y in the first equation:} \\&#10;x(25-x)=24 \\&#10;25x-x^2=24 \\&#10;-x^2+25x-24=0 \\&#10;-x^2+24x+x-24=0 \\&#10;-x(x-24)+1(x-24)=0 \\&#10;(-x+1)(x-24)=0 \\&#10;-x+1=0 \ \lor \ x-24=0 \\&#10;x=1 \ \lor \ x=24 \\ \\&#10;y=25-x \\&#10;y=25-1 \ \lor \ y=25-24 \\&#10;y=24 \ \lor \ y=1

The numbers are 1 and 24.
