Answer:
(68/4) multiply by 3601
Step-by-step explanation:
The focal length of the given ellipse is given as (±6, 0)
<h3>Equation of an ellipse</h3>
An ellipse is defined as a regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant or when a cone is cut by an oblique plane which does not intersect the base.
The standard equation of an ellipse is expressed as;
x^2/a^2 + y^2/b^2 = 1
The formula for calculating the focus of the ellipse is given as:
c^2 = b^2 - a^2
Given the equation of an ellipse
(x-7)^2/64 + (y-5)^2/100 = 1
This can also be expressed as:
(x-7)^2/8^2 + (y-5)^2/10^2 = 1
Comparing with the general equation
a = 8 and b = 10
Substitute
c^2 = 10^2 - 8^2
c^2 = 100 - 64
c^2 = 36
c = 6
Hence the focal length of the given ellipse is given as (±6, 0)

Answer:
D
Step-by-step explanation:
im just guessing sorry if its wronh
Ok, so the only possible/reasonable answer is:
Yesenia has 1 base ten block and 7 cubic inches blocks.
(8 blocks in total)
(total units: 17)
while, Misty has 6 base ten blocks and 8 cubic blocks.
(14 blocks in total)
(total units: 68)
68+17=85 (85 is the total number of units, with Misty and Yesenia added together, as said in the word problem)
14-8=6 (6 is the total number of blocks Misty has more the Yesenia, as said in the word problem)
14+8=22 (22 is the total number of blocks Misty and Yesenia have altogether)
