The answer is 130.5 square inches
Step-by-step explanation:
-2, -8/3, -10/3, -4, -14/3
Write as multiples of 1/3.
-6/3, -8/3, -10/3, -12/3, -14/3
This is an arithmetic sequence where the first term is -6/3 and the common difference is -2/3.
Therefore, the recursive formula is:
aᵢ₊₁ = aᵢ − 2/3, a₁ = -2
Edited:
(-1,3)
read the text wrong. but the method below holds :D
Step-by-step explanation:
The intersection of the AC line with the BD line is at (1,3)
method: hold an old receipt on my phone screen. would describe it as a graphically approach to the solution
on paper a ruler would be enough to draw the two mentioned lines.
do you need an algebraic way to do it?
The form of an eclipse is written as:
(x-h)^2/b^2 + (y-k)^2/a^2 = 1
Matching the values in the given equation tot he form of an eclipse you have:
a = 6
b = 4
k = 0
h = 0
A is the radius of the major axis and b is the radius of the minor axis.
H is the X offset and K is the Y offset.
The first vertex is written as (h, k+a)
Replacing the letters with their values you get:
(0, 0+6) = (0,6)
The second vertex is written as (h, k-a)
Replacing the letters with their values you get:
(0, 0-6) = (0,-6)
The vertices of the are (0,6) and (0,-6)
The vertices are the end points of the major axis, since 6 and -6 are longer than the minor axis of -4, 4 the ellipse has a vertical major axis
Compatible Numbers are numbers that are easy to divide mentally
