Answer:
Step-by-step explanation:
= n^2 + (3n^2 + 3n + 1 / n-3) = 3n
= BTW (/ = Fraction) and ^ means exponent
= n^2 + 3n + (12n + 1 / n - 3) = 12
= 37 / n - 3
Answer: n^2 + 3n + 12 +( 37 / n - 3)
Hope this helps :D
Answer:
A). 101 inches
B). 110 years
Step-by-step explanation:
Years since planting Circumference Difference
1 3 -
2 5 (5 - 3) = 2
3 7 (7 - 5) = 2
4 9 (9 - 7) = 2
5 11 (11 - 9) = 2
6 13 (13 - 11) = 2
There is a difference of 2 in every successive term of the circumference.
Therefore, the given sequence is an arithmetic sequence.
Explicit formula of an arithmetic sequence is given by,
Here a = first term
n = number of terms
d = common difference
From the given table,
Here = circumference after 'n' years
n = Age of the plant
By this formula,
Circumference of a tree after 50 years,
= 101 inches
Age of tree with the circumference = 221 inches,
221 = 2n + 1
2n = 220
n = 110 years
Answer:
the slope (or rise over run) is 2/3x, and the y intercept is -2
Step-by-step explanation:
In order to find the slope:
- subtract 2x from itself, cancelling it out. Do the same to the other side (-6).
- it should then look like this: 3y=-2x+-6
- next divide 3 from y as well as from -2 and -6.
- it should then look like this: y=2/3x+-2
Answer: B.
I kinda just had to think about it for a few seconds then found the anwser
Answer:
x > -1
Step-by-step explanation:
p = (f o g)(x) = log ((x+4)-3)
p = log (x+1)
so that p has a value,
the value of x + 1 mus be greater than 0
x + 1 > 0
x > -1
so the domain is x > -1
Domain = {x | x > -1, x must real number}
