Answer:

The value of your equation would be 371/30

Step-by-step explanation:

Given tanθ=8/15 - -(1)

sec^2θ

= 1+tan^2θ

= 1+(8/15)^2

= 1+64/225

= 225+64/225

= 289/225

=17^2+15^2

Now, secθ = \sqrt{\frac{17^2}{15^2} }

= 17/15

Cosθ = 15/17 - -(2)

Value of sinθ+cosθ/cosθ(1-cosθ)

Dividing numerator and denominator by cosθ, we get

= sinθ+cosθ/cosθ/cosθ(1-cosθ)/cosθ

= (sinθ/cosθ+cosθ/cosθ)/(1-cosθ)

= tanθ - 1/1-cosθ

= 8/15 + 1/1-15/17

= 8+15/15/17-15/17

= 23/15/2/17

= 23/15 x 17/2

= 371/30

Hope this helps!

Answer:

p=\frac{181}{301}

Step-by-step explanation:

30100 have dogs, 18100 have cats.

The question simply asks for a union scenario thus the law of AND & OR is applicable.

Therefore:-Those who have both cats and dogs partially have cats.

P(X=both \ cat \ and \ dog)=\frac{18100}{30100}\\p=\frac{181}{301}

Multiply (2n + 2)(2n – 2) A. 4n 2 – 4 B. 4n 2 – 4n – 4 C. 4n 2 + 2n – 4 D. 4n 2 + 4n – 4
sattari [20]
This system can be a bit tricky unless you write it out:
(2n + 2)(2n - 2) ~ First you have to take one variable and multiply it to each of the other two variables, like:
2n * 2n ~ And:
2n * -2 ~ This gives you:
4n^2 - 4n
Now we do this with the other:
2 * 2n
2 * -2
4n - 4
Now we combine them both while adding like terms:
4n^2 - 4
Therefore your answer is: A. 4n^2 - 4
(This is due to how when having the positive 4n subtracted by the negative it cancels it out. Leaving us with the remaining two terms left.)

I hope this helps, have a great rest of your day! ^ ^
