Answer:
{1,6}
Step-by-step explanation:
the second box is always where the y values/range are
Answer:
A1 = 18
A(n) = A (n-1) -2
Step-by-step explanation:
N represents the number in a sequence and the difference in the sequence is -2 since each time the number is listed in the sequence it is divide by 2.
Answer:
Answer:
n = 1
Step-by-step explanation:
This equation is just basic alegebra. First, combine like terms to get
9 - n = 8n. (Because 3 - 3 = 0, and -4n + 3n = -n.) Now the equation is much simpiler; add n to both sides to get 9 = 9n. Divide 9 by both sides to get that n = 1.
You can check your answer by plugging 1 in for n.
9 - 4(1) + 3(1) = 8(1) + 3 - 3
9 - 4 + 3 = 8 + 3 - 3
5 + 3 = 11 - 3
8 = 8
Therefore, n is proven to equal 1.
Hope this is helpful kid sorry i went very far yesterday hope you can forgive me but Anyways here it is <3
Volume of a cylinder = the area of the base x height of the cylinder
Area of base =

r^2
A = 6^2(

)
A = 36

V = 36

x 12
V = 432

5 cylinders = 5V
5V = 5 x (432

)
5V = 2160

Final answer: Alex needs to buy 2160

or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.
