A. would be the correct choice because the x+y hast to =1.
Answer:
The answer would be 5.03x10^-3 ^-^
Step-by-step explanation:
Answer: y ≥ 55
Step-by-step explanation:
Hi, to answer this question we have to write an inequality with the information given:
<em>Visitor must not be less than 55 years old.
</em>
So, “must not be less than 55” means a visitor age must be greater than 55 or equal to 55 to get the senior admission rate.
y ≥ 55
Whree "y" represents the age (in years) of a visitor
Feel free to ask for more if needed or if you did not understand something.
Answer:

Step-by-step explanation:
So an ellipse can be expressed in two different but very similar forms:
<u><em>Horizontal Major Axis:</em></u>
<u><em>Vertical Major Axis</em></u>:

In both equations the length of the major axis is "2a" and the length of the minor axis is "2b"
In the equation you provided, the major axis is horizontal, and the minor axis is vertical.
So looking at the horizontal length, you can see that it's 6, and since this ellipse has a horizontal major axis, that means 2a=6, which means a=3
Looking at the vertical length, you can see that it's 4, and since the ellipse has a vertical minor axis, that means 2b=4, which means b=2
The last thing to note is that the center of an ellipse is (h, k) in the equation, and since here the center is (0, 0) it's (x-0)^2 and (y-0)^2 in the denominator which is just x^2 and y^2
So let's plug in the values into the equation:

(h, k) = (0, 0)
a = 3
b = 2

Answer:
Step-by-step explanation:
a^2 + b^2 = c^2
8^2 + 15^2 = c^2
64 + 225 = c^2
289 = c^2
c= 
c= 17
