HELP. How long is the minor axis for the ellipse shown below?
kifflom [539]

Given:

The equation of ellipse is

\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1

To find:

The length of the minor axis.

Solution:

The standard form of an ellipse is

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

where, (h,k) is center, if a>b, then 2a is length of major axis and 2b is length of minor axis.

We have,

\dfrac{(x+4)^2}{25}+\dfrac{(y-1)^2}{16}=1      ...(ii)

On comparing (i) and (ii), we get

b^2=16

Taking square root on both sides.

b=\pm 4

Consider only positive value of b because length cannot be negative.

b=4

Now,

Length of minor axis = 2b

                                  = 2(4)

                                  = 8

So, the length of minor axis is 8 units.

Therefore, the correct option is B.

Which quadratic function has Vertex (-1,4) and passes through (4,19) <br> HELP
hichkok12 [17]

Answer:

f(x)=\frac{3}{5}(x+1)^2+4

Step-by-step explanation:

The equation of a quadratic function in vertex form is given by:

f(x)=a(x-h)^2+k

Where (h,k) is the vertex.

It was given in the question that the vertex of the parabola is (-1,4).

When we substitute the vertex into the formula we get:

f(x)=a(x+1)^2+4

The parabola also passes through (4,19) hence it must satisfy its equation.

19=a(4+1)^2+4

19-4=a(5)^2

15=25a

We divide both sides by 25 to get:

a=\frac{15}{25}= \frac{3}{5}

Hence the quadratic function is:

f(x)=\frac{3}{5}(x+1)^2+4
