Answer:
The degree of polynomial of 57 is 0.
Answer:
where is the pic
Step-by-step explanation:
Okay, here we have this:
Considering the provided angle, we are going to calculate the requested trigonometric functions, so we obtain the following:
So the first thing we will do is calculate the length of the hypotenuse, that is, the distance between the given point and the origin, then we have:
![\begin{gathered} r=\sqrt{(12-0)^2+(-5-0)^2} \\ r=\sqrt{12^2+(-5)^2} \\ r=\sqrt{144+25} \\ r=\sqrt{169} \\ r=13 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20r%3D%5Csqrt%7B%2812-0%29%5E2%2B%28-5-0%29%5E2%7D%20%5C%5C%20r%3D%5Csqrt%7B12%5E2%2B%28-5%29%5E2%7D%20%5C%5C%20r%3D%5Csqrt%7B144%2B25%7D%20%5C%5C%20r%3D%5Csqrt%7B169%7D%20%5C%5C%20r%3D13%20%5Cend%7Bgathered%7D)
Now we proceed to find the value of each ratio:
![sin\beta=\frac{y}{r}=\frac{-5}{13}](https://tex.z-dn.net/?f=sin%5Cbeta%3D%5Cfrac%7By%7D%7Br%7D%3D%5Cfrac%7B-5%7D%7B13%7D)
![cos\beta=\frac{x}{r}=\frac{12}{13}](https://tex.z-dn.net/?f=cos%5Cbeta%3D%5Cfrac%7Bx%7D%7Br%7D%3D%5Cfrac%7B12%7D%7B13%7D)
![tan\beta=\frac{y}{x}=\frac{-5}{12}](https://tex.z-dn.net/?f=tan%5Cbeta%3D%5Cfrac%7By%7D%7Bx%7D%3D%5Cfrac%7B-5%7D%7B12%7D)
![csc\beta=\frac{r}{y}=\frac{13}{-5}=-\frac{13}{5}](https://tex.z-dn.net/?f=csc%5Cbeta%3D%5Cfrac%7Br%7D%7By%7D%3D%5Cfrac%7B13%7D%7B-5%7D%3D-%5Cfrac%7B13%7D%7B5%7D)
![sec\beta=\frac{r}{x}=\frac{13}{12}](https://tex.z-dn.net/?f=sec%5Cbeta%3D%5Cfrac%7Br%7D%7Bx%7D%3D%5Cfrac%7B13%7D%7B12%7D)
Answer:
Step-by-step explanation:
Let the number of the problems the team could solve before is x.
<u>Then we have:</u>
- x + 40% = 42
- 1.4x = 42
- x = 42/1.4
- x = 30
They were able to solve 30 problems before the new mathletes joined
