Answer:
Alright well use the Graph line using the slope and the y-intercept, or two points
Slope: - 1
y - intercept: - 2
X: 0, 1
Y: - 2, - 3 Hope this helps :)
Step-by-step explanation:
Answer:
There are 
rows in the theater.
Step-by-step explanation:
Given terms.
Seats in order 
will form an Arithmetic progression.
As the common difference 
,same for three consecutive terms so this an AP.
Now accordingly we can put the AP terms.
Total number of seats 
Seats in the first row 
Seats in the last row 
Summation of 
terms in AP
![S_n={\frac{n}{2}[2a+(n-1)d]}](https://tex.z-dn.net/?f=S_n%3D%7B%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D%7D)
OR
![S_n=\frac{n}{2}[a+l]](https://tex.z-dn.net/?f=S_n%3D%5Cfrac%7Bn%7D%7B2%7D%5Ba%2Bl%5D)
Using the second equation.
![1560=\frac{n}{2}[23+81]](https://tex.z-dn.net/?f=1560%3D%5Cfrac%7Bn%7D%7B2%7D%5B23%2B81%5D)
So the number of rows (n) in the theater 
Answer:
I don't see anything
Step-by-step explanation:
Answer:
sinθ = -0.554
tanθ = -0.667
secθ = 1.203
Step-by-step explanation:
Consider the point (3, -2)
The value of x is positive and the value of y is negative.
It means the the terminal sides of angle lies in 4rth quadrant, such that:
Base = 3
Perpendicular = 2
Hypotenuse² = 2² + 3²
Hypotenuse = 3.61
sinθ = Perpendicular /Hypotenuse
sinθ = 2/3.61
As sine is negative in 4rth quadrant
sinθ = - (2/3.61)
sinθ = -0.554
tanθ = Perpendicular/ Base
tanθ = 2/3
tanθ = 0.667
As tan is negative in 4rth quadrant
tanθ = -0.667
secθ = Hypotenuse/Base
secθ = 3.61/3
secθ = 1.203
secant is positive in 4rth quadrant
