Answer:
A
Step-by-step explanation:
In standard form, an ellipse's major axis is indicated by the 
terms like this:
In the top equation, the vertical axis is primary and in the second the horizontal axis is primary. That's a bit more info than the question asked, but I thought it may be helpful to understand the answer.
Now, a co-vertex is the intersection point between an ellipse and its minor axis. On the graph of the ellipse, the 
is the distance from the center to where the ellipse intersects its minor axis, so our answer is A.
If a graphical representation would be helpful, I would take a look at the Math Warehouse article on the Equation of an Ellipse in Standard Form.
Answer:
14/20 is simplified to 7/10. 16/24 is simplified to 2/3 they are not proportional.
Step-by-step explanation:
Answer:
(5.9 , 1)
Step-by-step explanation:
(1 , 0) (1 , 2) length = 2
Third vertex ( x , y)
(x - 1)² + (y - 0)² = 5²
(x - 1)² + (y - 2)² = 5² isosceles triangle
(y - 2)² - y² = 0
-4y + 4 = 0
y = <u>1</u>
(x - 1)² + (1 - 0)² = 5²
(x - 1)² = 24
x - 1 = ± 2√6
x = 1 + 2√6 or x = 1 - 2√6
X in the 1st quadrant x = 1+2√6 = <u>5.9</u>
Answer:
z + 7
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
The sum of z and 7
<em>z + 7</em>
<em />
Answer: z + 7
<u>If needed solve:</u>
z + 7 - 7 = 0 - 7
<em>z = -7</em>
