7 is C this is because if you pluge the x value into the equation and it gives you the y value associated with it for all the points, then it is the correct equation.

8 is A and this is the same principle

9 is C because b = 6h-3 and put this in the equation for a triangle and you get 1/2 (6h-3)h and put into one equation is (6h^2 - 3h)/2

A number is chosen at random from 1 to 10. Find
Allisa [31]

Answer:

1/2

Step-by-step explanation:

The possible outcomes are

1,2,3,4,5,6,7,8,9,10

Factors of 6 are 1,2,3,6

or a 4

1,2,3,4,6 are the outcomes we want

There are 5 "good" outcomes

P( 4 or a factor of 6) = "good" outcomes/ total

                                  = 5/10

                                   =1/2

Identify the vertical asymptotes of f(x) = quantity x minus 4 over quantity x squared plus 13 x plus 36
choli [55]
Expression: f(x) = [x - 4] / [x^2 + 13x + 36].

The vertical asympotes is f(a) when the denominator of f(x) is zero and at least one side limit when you approach to a is infinite or negative infinite.

The we have to factor the polynomial in the denominator to identify the roots and the limit of the function when x approachs to the roots.

x^2 + 13x + 36 = (x + 9)(x +4) => roots are x = -9 and x = -4

Now you can write the expresion as: f(x) = [x - 4] / [ (x +4)(x+9) ]

Find the limits when x approachs to each root.

Limit of f(x) when x approachs to - 4 by the right is  negative infinite and limit when x approach - 4 by the left is infinite, then x = - 4 is a vertical asymptote.

Limit of f(x) when x approachs to - 9 by the left is  negative infinite and limit when x approach - 9 by the right is infinite, then x = - 9 is a vertical asymptote.

Answer: x = -9 and x = -4 are the two asymptotes.
