Answer:
Tn = 6.4 + 1.8n
Step-by-step explanation:
Given
Sequence: 8.2, 10, 11.8, 13.6
Required
The formula of the sequence.
First, the type of the sequence needs to be determined (arithmetic or geometric)
It is an arithmetic sequence because each successive sequence is separated by a common difference..
The common difference is represented by d and it's calculated as follows.
d = 10 - 8.2 or 11.8 - 10 or 13.6 - 11.8
Each of the above gives
d = 1.8
Now, that we have the common difference; the next is to determine the formula using the Arithmetic Progression formula.
Tn = T1 + (n - 1)d
Where T1 is the first term of the progression; T1 = 8.2
By substituting 8.2 for T1 and 1.8 for d.
This gives
Tn = 8.2 + (n - 1) * 1.8
Open bracket
Tn = 8.2 + 1.8 * n - 1 * 1.8
Tn = 8.2 + 1.8n - 1.8
Collect like terms
Tn = 8.2 - 1.8 + 1.8n
Tn = 6.4 + 1.8n
Hence, the formula of the sequence is Tn = 6.4 + 1.8n
Answer:
see explanation
Step-by-step explanation:
to find the intercepts, that is where the line crosses the x and y axes
• let x = 0, in the equation for the y-intercept
• let y = 0, in the equation for x-intercept
x = 0
⇒ - 5 = 4y ( divide both sides by 4 )
y = - 
← y- intercept
y = 0
7x - 5 = - 6x ( add 6x to both sides )
13x - 5 = 0 ( add 5 to both sides )
13x = 5 ( divide both sides by 13 )
x = 
← x- intercept
Ahhhh simoooooooooooooooooon weeeeeeee
