For the right triangle shown, which expression represents the length of CB?
A) 6 cos(35°)
B) 6 tan(35°)
C)
6
sin(35°)
D)
cos(35°)
6

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

a. -0.3 > -0.33

it would open into a square depending on the type of envelope i’m not sure about the second part

$6.42
