<span>= cos(x) / ( 1/cos(x) - sin(x)/cos(x) ) </span>
<span>= cos² (x) / ( 1 - sin(x) ) </span>
<span>= ( 1 - sin² (x) ) / ( 1 - sin(x) ) </span>
<span>= ( 1 - sin(x) ) ( 1 + sin(x) ) / ( 1 - sin(x) ) </span>
<span>= 1 + sin(x)</span>

For which graph is the parent function ?
Deffense [45]

Answer:

parent function is the simplest function that still satisfies the definition of a certain type of function. For example, when we think of the linear functions which make up a family of functions, the parent function would be y = x. This is the simplest linear function.

The parent function of a square root function is y = √x

assuming the pick-up trucks trailers and road conditions are exactly the same which vehicle will take a longer distance to stop
NemiM [27]

I’ve answered this before so I know the question is missing an

important given and that given is: 1 has an

empty trailer and the other has a fully loaded one. 



So, it would be the fully loaded trailer that would take a longer distance to

stop because a lot of weight is being pulled, and when the brakes are started,

the fully loaded trailer is more like pushing against the truck.

3.Simplify the expression. 9xy2 – 11xy2 show your work
GalinKa [24]
Ok so 9x minus 11x you get -2x then the two y^2 cancel each other out to get -2x if the y^2 is separate from the x variable. However if its all one then it would be just 9 minus 11 to get -2 then putting the variable back on the end to get -2xy^2.
