Jill jogs 1/2 mile in 1/10 hour.. whats jills rate mile per hour

5 miles per hour, because to actually find her jogging rate, you need to multiply her distance by the denominator of her time, which comes out to be 1/2 times 10.

PLEASE HELP!! Find the equation of the line that is perpendicular to y= -2/3x and contains the point (4,-8).

AlladinOne [14]

Answer:

y = 3x/2 +14

Step-by-step explanation:

gradient = -2/3

so if perpendicular,

-2/3 * m2 = -1

m2 = 3/2

if crosses throguh ( -4, 8 )

y - 8 = 3/2 ( x - - 4)

y = 3x/2 + 14

Answer:

No, the inverse function does not pass the vertical line test.

Step-by-step explanation:

Remember that $h(x)=y$ . To find the inverse of our function we are going to invert x and y and solve for y:

$h(x)=x^2+3$

$y=x^2+3$

$x=y^2+3$

$x-3=y^2$

$y=\pm\sqrt{x-3}$

$h^{-1}(x)=\pm\sqrt{x-3}$

Now we can graph our function an perform the vertical line test (check the attached picture).

Remember that the vertical line test is a visual way of determine if a relation is a function. A relation is a function if and only if it only has one value of y for each value of x. In other words, a relation is a function if a vertical line only intercepts the graph of the function once.

As you can see in the picture, the vertical line x = 15 intercepts the function twice, so the inverse function h(x) is not a function.

We can conclude that the correct answer is: No, the inverse function does not pass the vertical line test.
