Mathematics

The graph represent a horizontal ellipse with center ,(h,k)=(-1,3)

Length of major axis, 2a =8-(-10) = 18

Therefore, a = 9

And length of minor axis, 2b =5-1 =4

Therefore b=2

The formula that we have to use to find the vertices

(h+-a,k)

(-1+-9,3) = (-1-9,3),(-1+9,3) = (-10,3),(8,3)

we need to find the vertices of given diagram using graph

we know that diagram looks in the from of ellipse

we know that ellipse is horizontal major axis ellipse which means major axis lies in x axis . we know that ellipse will have two vertices

we know that length of major axis =20 units from graph as we stretch from left to right corner .we need to divide to get semi major length so semi major length is 10 and -10

so one vertices (0,10) and other one is (0,-10) .

Find the maximum and minimum values of the function. y=1/2sin2x
kykrilka [37]

Answer:  

(-1/2,1/2)

Step-by-step explanation:

Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.

hope it helped

What numbers would you subtract from each side of the equation x + 12 = 17 + 3 to get the variable by itself ?
kenny6666 [7]
The number you would subtract on both sides would be 12... but this in  and of itself is not the first step. the way you would solve this is by:
combine like terms. x + 12=20
then, subtract 12 from both sides to get variable alone.
you will end up with a final answer of x=8
