Answer:
V = 45
Step-by-step explanation:
45 divided by 5 = 9
:))
Answer:18
Step-by-step explanation:
Note: Mathematicians start counting at 1, so by convention, n=1 is the first term. So we must define what the first term is. Then we have to figure out and include the common difference.
Taking a look at the examples again,
Sequence: 1, 2, 3, 4, … | Formula: a(n) = n + 1 | Recursive formula: a(n) = a(n-1) + 1, a(1) = 1
Sequence: 3, 8, 13, 18, … |Formula: b(n) = 5n - 2 | Recursive formula: b(n) = b(n-1) + 5, b(1) = 3
okay well first you should put it in slope-intercept form aka y = mx + b
but you have simplify everything first
2(x + 3) + 2(y + 2) = 16
2x + 3 + 2y + 4 = 16
2x + 2y + 7 = 16
-7 -7
2x + 2y = 9
-2x -2x
2y = -2x + 9
/2 /2
y = -x + 4.5
so now in a graph it should look like this:
Area formula: pi * radius * radius
Radius=1/2diameter=1/2(7)=3.5
3.5*3.5*pi=12.25pi square feet
Circumference formula: pi * diameter
7*pi=7pi feet
