Sine = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent
You have three other trig functions: secant, cosecant, and cotangent.
Cosecant = hypotenuse/opposite
Secant = hypotenuse/adjacent
Cotangent = adjacent/opposite
The way I’ve always remembered these is the 3 other trig functions are sine, cosine, and tangent flipped. Sine’s opposite is cosecant. Cosines opposite is secant, and tangents opposite is cotangent.
If you notice, each of these functions has a word starting with co-, and a word starting without co-. That’s how I’ve always remembered that sine goes to cosecant and cosine goes to secant.
Now that we know secant (or sec for short) x = hypotenuse/adjacent, you can find it.
First, find the hypotenuse of the triangle. Use Pythagorean’s theorem to do this.
a^2 + b^2 = c^2
5^2 + 7^2 = c^2
25 + 49 = c^2
c^2 = 74
c = √74
Now plug the values for hypotenuse and adjacent into sec(x)
sec(x) = √74/7
Answer:
Step-by-step explanation:
Using the Pythagorean Theorem, (7)2 + (5)2 = c2 ⇒ c = 72
.
Since x = 1 /cos x = hypotenuse /adjacent , then sec x = √ 74/7

PLSSS HELP MEEE DUDE HELP MEEEEEE Marshall High School’s community service club will be selling baked goods as a fundraiser. The club members plan on making cupcakes and cookies. There will be 5 cookies made for every 2 cupcakes made. The club members plan on making 280 total baked goods.
Plot the point on the coordinate plane below that represents the total number of cupcakes and the total number of cookies that the community service club members plan on making for the fundraiser.
To plot the point, click the pencil tool and select the thickest brush size.
Answers
Answer:
See Explanation
Step-by-step explanation:
Let the number of cookies be x and the number of cupcakes be y.
If the total is 280, then
[tex]5x + 2y = 280[/tex]
Subtract 5x from both sides
[tex]5x - 5x + 2y = 280 - 5x[/tex]
[tex]2y = 280 - 5x[/tex]
Make y the subject
[tex]y = 140 - \frac{5}{2}x[/tex]
See attachment for graph
Any of the following equation can be plotted on the graph (they literally represent the same thing)
[tex]5x + 2y = 280[/tex]
[tex]2y = 280 - 5x[/tex]
[tex]y = 140 - \frac{5}{2}x[/tex]

Step-by-step explanation:
The given sequence: [tex]C(n) = -7 + 6(n - 1)[/tex] which represents the nth term.
To find 4th term.
Put n=4, we get
[tex]C(4) = -7 + 6(4 - 1)\\\\\Rightarrow\ C(4) = -7 + 6(3)\\\\\Rightarrow\ C(4) =-7+18\\\\\Rightarrow\ C(4) =11[/tex]
Hence, the 4th term is 11.
