Answer:
I tried to answer but I still would like to know what doesn't make sense.
Considering the identity:
![\sec^2\theta-\tan^2\theta=1 \implies |\sec\theta|\geq1](https://tex.z-dn.net/?f=%5Csec%5E2%5Ctheta-%5Ctan%5E2%5Ctheta%3D1%20%5Cimplies%20%7C%5Csec%5Ctheta%7C%5Cgeq1)
![$\forall\;\theta\in\mathbb{R}-\{(2n+1)\frac{\pi}{2}, n\in\mathbb{Z} \}$](https://tex.z-dn.net/?f=%24%5Cforall%5C%3B%5Ctheta%5Cin%5Cmathbb%7BR%7D-%5C%7B%282n%2B1%29%5Cfrac%7B%5Cpi%7D%7B2%7D%2C%20n%5Cin%5Cmathbb%7BZ%7D%20%5C%7D%24)
The identity is true whenever both sides are defined. It is not supposed to hold the values when we have division by zero, because it is undefined.
If the value doesn't make sense, it is probably not a function, or it is undefined by the given value of
.
Let's go back to the definition of function again:
A function relates a set of inputs and a set of allowable outputs where each input is related to only one output. It basically defines the relation of ordered pairs.

20/28 = 5/7
Step-by-step explanation:
Step 1 :
Total number of students in the algebra class is 28
Given that the number of students who play neither sport = 8
Step 2 :
Probability that a student randomly chosen does not play any sport is obtained by number of students who play neither sport/ total number of students
Hence probability is 8/28
Step 3 :
The probability that a student randomly chosen plays either basketball or base ball = 1 - 8/28 = 20/28 = 5/7
Answer:
y-intercept is the weight of the animal at birth (when x = 0)
Step-by-step explanation:
![y=3.86x+15](https://tex.z-dn.net/?f=y%3D3.86x%2B15)
The slope (gradient) of the function is 3.86
The y-intercept of the function is 15
Therefore, the y-intercept is the weight of the animal at birth (when x = 0)
