URGENT If the sine of a certain angle is 12/13, what could the cosine of that angle be?

Mathematics
1 answer:
True [87]3 years ago
7 0

Answer:

5/13

Step-by-step explanation:

Sine is equal to the length of the opposite side divided by the length of the hypotenuse, while cosine is equal to the length of the adjacent side divided by the hypotenuse. Since you know that the opposite side has length 12 and the hypotenuse has length 13, you can use the pythagorean theorem to find that the length of the third (adjacent) side is \sqrt{13^2-12^2}=5. Therefore, the cosine of that angle is 5/13. Hope this helps!

PLEASE HELP!!!! IMA DESPRATE!!!!!!!!Find the second term in the sequence defined by an = −5(n2 + 1n).
Dmitrij [34]

The second term of the given sequence aₙ = -5(n² + 1n) when solved gives us; a₂ = -20

<h3>How to find the nth term of a sequence?</h3>

We are given the formula for a sequence as;

aₙ = -5(n² + 1n)

Where n is the position of the term.

Now, for the first term, we will have;

a₁ = -5(1² + 1(1))

a₁ = -10

The second term of the sequence is;

a₂ = -5(2² + 1(2))

a₂ = -20

We have 
f(x)=<span>−x</span>²<span>+ 5x + 6
g(x)=</span><span>3x − 2

we know that
f(x)=g(x)
the solution is the intersection both graphs

using a graph tool
see the attached figure

the solution are the points
