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.
Hope it helped you a bit.
Answer:
Step-by-step explanation:
We have been given an equation:
y=5x+3
The above equation is the equation of line
If we compare the given equation with general equation of line which is y=mx+c
Where. m is the slope of line.
Here on comparing we get
m=5 and c=3
To find x-intercept put y=0
Its x-intercept is (-0.6,0)
To find y-intercept put x=0
Its y-intercept is (0,3)

Answer:
155 miles
Step-by-step explanation:
52.95 + 33.75 = 86.7
140.95 - 86.7 = 54.25
54.25 / .35 = 155
155 miles
Answer:
The fraction of males who are smokers = 10/500 = 1/50
The fraction of females who are smokers = 40/403
The probability that both are smokers is the product of these two:
P(both) = (1/50)*(40/403) = (4/5)*(1/403)
