We have the following function:
N (k):
Where, the indepent variable is k
The dependent variable is N
For the function:
k (n):
the independent variable is n
The dependent variable is k
Thus,
N (12) = 4
k (4) = 12
Answer:
TRUE
option A
HEY THERE !!
3y= 6
Dividing by 3 on both sides
y = 2
And it's graph is in the attachment.
Answer:
Car B = 43 miles per gallon
Car A = 43+4=47 miles per gallons
Step-by-step explanation:
Let the mileage of Car B be x miles per gallon
Hence the mileage of Car A will be x+4 miles per gallon
Distance traveled by each car in 1 gallon
Car A = x+4
Car B = x
Total Distance covered by both car in 1 gallon = x+(x+4) which is given as 90 miles
Hence x+(x+4)=90
2x+4=90
2x=86
dividing both sides by 2 we get
x=43
Mileage of Car B = 43 miles per gallon
Mileage of Car A = 43+4=47 miles per gallons
Answer:
a) Arithmetic
b) 22.5
c) 4.5
d) a_n = 4.5 + 4.5(n - 1)
e) a_15 = 67.5
Step-by-step explanation:
a) Subtract one term by the term right before it, and the difference will be the common difference.
9 - 4.5 = 4.5
13.5 - 9 = 4.5
18 - 13.5 = 4.5
Therefore, the common difference is 4.5.
b) Since the common difference is 4.5, add 4.5 to the 18 (which was the last value given). The result is 22.5.
c) We have already figured out that the common difference is 4.5.
d) The explicit formula would be a_n = a1 + d(n - 1). The first term is 4.5 and d is also 4.5, so the explicit formula is a_n = 4.5 + 4.5(n-1).
e) Plug 15 into our explicit formula for n. a_15 = 4.5 + 4.5(14). The result is 67.5.
You would need to distribute the 3 on the left side and the -6 on the right side. p=7/3
