Answer:
y=3x+5
Step-by-step explanation:
Point slope equation:
y=mx+b
m-slope, b- is y-intercept
equation given 2 points
y-y1 = m(x-x1)
For point (1,8) and slope m=(y2-y1)/(x2-x1) = 20-8/5-1=12/4=3
y-8 =3(x-1)
arange it in point slope format
y-8=3x-3
y=3x-3+8
y=3x+5
Solution: csc stands for cosecant
csc (2n+1) x 180˚
= Csc (360n +180)
= csc (180) and the csc has a period of 360˚
= 1/ sin (180)
As sin 180 = 0 so,
csc ((2n+1) x 180 degrees) is undefined as 1/0 is undefined when you calculate it in the calculator.
Answer:
f(-2) = -1
Step-by-step explanation:
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1
Given:
The given sequence is:
To find:
The recursive formula for 
, the nth term of the sequence.
Solution:
We have,
Here, the first term is 5.
The common difference is -7.
The recursive formula for the nth term of the sequence is
Where, 
is the common difference.
Putting 
in the above formula, we get
Therefore, the recursive formula for the nth term of the sequence is .
