What is the vertex point of y= - 2+3? Enter your answer as an ordered pair, e.g. (1,2).
Anettt [7]

Answer:

y=1, so (0, 1)

Step-by-step explanation:

Just subtract 3 from -2. Since there is no x in the problem, it means that this line is horizontal, meaning that the x can change but the y has to stay at 1.

The line is horizontal so there is no vertex point

Write the equation of the ellipse with center (4,2), vertex (9,2), and focus (4+2sqrt5,2)
dangina [55]

Answer : option B

Given: center (4,2), vertex (9,2), and focus (4+2sqrt5,2)

The distance between vertex and center is 9-4 = 5

Center is (h,k) so h= 4  and k =2

focus is (h+c,k)

From the given focus (4+2sqrt5,2), c= 2sqrt(5)

Standard form of equation is

\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}=1

h= 4, k=2, a=5, c=2sqrt(5), we need to find out b

c^2 = a^2 - b^2

b^2 = a^2 - c^2

b^2 = 5^2 - (2\sqrt{5})^2

b^2 = 25 - 20

b^2 = 5

plug in all the values

\frac{(x-h)^2}{a^2} + \frac{(y-k)^2}{b^2}=1

\frac{(x-4)^2}{25} + \frac{(y-2)^2}{5}=1

Option B is correct
