True
EXPLANATION
The given trigonometric equation is:
![{ \tan}^{2} x + 1 = { \sec}^{2} x](https://tex.z-dn.net/?f=%20%7B%20%5Ctan%7D%5E%7B2%7D%20x%20%2B%201%20%3D%20%7B%20%5Csec%7D%5E%7B2%7D%20x)
We take the LHS and simplify to arrive at the RHS.
![{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x}{{ \cos}^{2} x} + 1](https://tex.z-dn.net/?f=%7B%20%5Ctan%7D%5E%7B2%7D%20x%20%2B%201%20%3D%20%20%5Cfrac%7B%7B%20%5Csin%7D%5E%7B2%7D%20x%7D%7B%7B%20%5Ccos%7D%5E%7B2%7D%20x%7D%20%20%2B%201)
Collect LCM on the right hand side to get;
![{ \tan}^{2} x + 1 = \frac{{ \sin}^{2} x + {\cos}^{2} x}{{ \cos}^{2} x}](https://tex.z-dn.net/?f=%7B%20%5Ctan%7D%5E%7B2%7D%20x%20%2B%201%20%3D%20%20%5Cfrac%7B%7B%20%5Csin%7D%5E%7B2%7D%20x%20%2B%20%7B%5Ccos%7D%5E%7B2%7D%20x%7D%7B%7B%20%5Ccos%7D%5E%7B2%7D%20x%7D%20)
This implies that
![{ \tan}^{2} x + 1 = \frac{1}{{ \cos}^{2} x} .](https://tex.z-dn.net/?f=%7B%20%5Ctan%7D%5E%7B2%7D%20x%20%2B%201%20%3D%20%20%5Cfrac%7B1%7D%7B%7B%20%5Ccos%7D%5E%7B2%7D%20x%7D%20.)
![{ \tan}^{2} x + 1 = {( \frac{1}{ \cos(x) }) }^{2}](https://tex.z-dn.net/?f=%7B%20%5Ctan%7D%5E%7B2%7D%20x%20%2B%201%20%3D%20%20%7B%28%20%5Cfrac%7B1%7D%7B%20%5Ccos%28x%29%20%7D%29%20%7D%5E%7B2%7D%20)
![{ \tan}^{2} x + 1 = { \sec}^{2} x](https://tex.z-dn.net/?f=%7B%20%5Ctan%7D%5E%7B2%7D%20x%20%2B%201%20%3D%20%20%7B%20%5Csec%7D%5E%7B2%7D%20x)
This identity has been verified .Therefore the correct answer is true.
Here we must write and solve a linear equation to find the number of miles that Arun traveled in the taxi. We will find that Eva traveled 11 miles.
So we know that the taxi charges a fee of $4.10 and then a plus of $0.50 per mile.
So if you travel for m miles, the cost equation is:
C(m) = $4.10 + $0.50*m
Now, we know that for Eva the total fare (total cost) was $9.60, then we need to solve:
$9.60 = C(m) = $4.10 + $0.50*m
$9.60 = $4.10 + $0.50*m
$9.60 - $4.10 = $0.50*m
$5.50 = $0.50*m
$5.50/$0.50 = m = 11
This means that Arun traveled 11 miles in the taxi.

Answer:
Reliability
Step-by-step explanation:
The Reliability of a measurement or observation refers to its repeatability. If you measure or observe the same thing twice, how close are the two measurements or observations?
#The test results 110 1nd 150 are between 27% and 36% depending on which direction you take. That variation is wide apart and the test can't be considered reliable.
