Answer:

x=2

Step-by-step explanation:

Vertical lines have the same x value all the time.  It is of the form x=

Their slope is undefined

The line passes through the point (2,4) and the x value is 2

x=2

G = {(5, 3), (2, 3), (6, 4)} Is G-1 a function and why?
galben [10]
To get G^-1 all we need to do is flip the points around Example for (5,3) make it (3,5)
Here are the points in inverse (3,5); (3,2); (4,6)
To tell if a group of point can be a function we need to 1st look at the x values.  If all the x values are different, then it is a function (the x's are not all different)
If there are x values that are the same, they MUST have the same y value.
look at the points (3,5) and (3,2) those have the same x but they go to different y values so it is not a function.

You can think about it like this.  Can you go to more than 1 place at the EXACT same time?  Obvious answer is no. Can you have multiple people go to the same room?  Sure that is possible.  Same with functions.  An x value can ONLY go to 1 y value, and many different x values can go to the same y value.

Write the standard equation for the hyperbola with the following conditions: vertices: (-2, -3) and (6, -3) foci: (-4, -3) and (
STALIN [3.7K]
Hello,

Vertices are on a line parallele at ox (y=-3)

The hyperbola is horizontal.

Equation is (x-h)²/a²- (y-k)²/b²=1

Center =middle of the vertices=((-2+6)/2,-3)=(2,-3)
(h+a,k) = (6,-3)
(h-a,k)=(-2,-3)
==>k=-3 and  2h=4 ==>h=2
==>a=6-h=6-2=4 (semi-transverse axis)

Foci: (h+c,k) ,(h-c,k)
h=2 ==>c=8-2=6

c²=a²+b²==>b²=36-4²=20

Equation is:
\boxed{ \dfrac{(x-2)^2}{16} - \dfrac{(y+3)^2}{20} =1}&#10;&#10;

GREYUIT [131]

Answer:

99.7%

Step-by-step explanation:

Note that 92 and 128 are 3 standard deviations from the mean

The emperical rule or the  68–95–99.7 rule states that 68% of outcomes are wihtin 1 standard deviation from the mean

95% of outcomes are within 2 standard deviations from the mean

99.7% of outcomes are within 3 standard devations from the mean

This is 3 standard deviations so the answer is 99.7
