Assuming the first 5 terms are:
n = 0
n = 1
n = 2
n = 3
n = 4
a) 4n + 4
4(0) + 4 = 4
4(1) + 4 = 8
4(2) + 4 = 12
4(3) + 4 = 16
4(4) + 4 = 20
b) 8n + 3
8(0) + 3 = 3
8(1) + 3 = 11
8(2) + 3 = 19
8(3) + 3 = 27
8(4) + 3 = 35
c) 18 - 3n
18 - 3(0) = 18
18 - 3(1) = 15
18 - 3(2) = 12
18 - 3(3) = 9
18 - 3(4) = 6

Answer:
I'm sorry I don't know what that means so I just put the meaing for quadratic formula
Step-by-step explanation:
In elementary algebra, the quadratic formula is a formula that provides the solution to a quadratic equation. There are other ways of solving a quadratic equation instead of using the quadratic formula, such as factoring, completing the square, graphing and others
<em>I'm sry that this is not the answer you were probaly looking for but all you said was "Solve in quadratic formula" and theres nothing else so pls if you need to fix that pls do so you can get your answer- Lily~Senpai :P</em>
Answer:
Final graph is attached.
Solution is x=2, y=3
Step-by-step explanation:
As we have to solve by graphing to let's graph y=2x-1 first.
we are free to plug any number for x say x=0 and x=2
when x=0 then y=2x-1 changes to
y=2(0)-1=0-1=-1
Hence point is (0,-1)
Similarly
when x=2 then y=2x-1 changes to
y=2(2)-1=4-1=3
Hence point is (2,3).
Now we graph both points (0,-1) and (2,3) then join them by a straight line.
We repeat exactly same process for other line y=-x+5 and get points (0,5) and (2,3)
Now graph both to see the intersection point of both lines
We see that both lines intersect at point (2,3)
<u>Hence final answer is (2,3) or we can also write x=2, y=3.</u>
Answer:
Volume of Sphere is 33.51 ft^3
Volume of Cylinder is 37.7 m^2
Step-by-step explanation:
<u>Volume of a sphere formula: V = 4
/3πr^3</u>
<u>Volume of a cylinder formula: V = πr^2h</u>
<u />
<u>Step 1: Find the volume of the sphere</u>
Since it shows the diameter, you need to divide 4 by 2 to get the radius: 2
V = 4/3*π*(2)^3
<em>V = 33.51 ft^3</em>
<em />
Answer: Volume of Sphere is 33.51 ft^3
<u>Step 2: Find the volume of the cylinder</u>
Since it shows the diameter, you need to divide 4 by 2 to get the radius: 2
V = π*(2)^2*(3)
<em>V = 37.7 m^2</em>
<em />
Answer: Volume of Cylinder is 37.7 m^2
