Which of the following equations best describes a square root function that is reflected across the x-axis and has a vertex of (
Minchanka [31]

Answer:

C

Step-by-step explanation:

Rather than picking, let's try to construct one from the description.

reflected over the x axis means -\sqrt{x}

the vertex is usually at (0,0), now how do we move a graph?  or in other words  translating it.

To move left and right you use \sqrt{x-h} where if you subtract h you move right and if you add h you move left.  we go from (0,0) to (-4,2).  so 0 to -4 is 4 left, so that means we add 4.

To move up and down we use \sqrt{x}+v Here if v is positive you move up and if v is negative you move down.  going from (0,0) to (-4,2) it moves up 2

So now we put them all together -\sqrt{x+4}+2  And if you look, C matches that exactly.

Please help with this
prohojiy [21]

Answer:

Step-by-step explanation:

Recall that cos Ф = adj / hyp.  If adj = 6 and hyp = 10, then by the Pythagorean Theorem, opp = 8:    6² + 8² = 10²

Then:

sin Ф = opp / hyp = 8/10 or 4/5

cos Ф is given:         6/10 or 3/5

tan Ф = opp / adj:      8/ 6 or 4/3

cot Ф   = 1/sin Ф = 10/8 or 5/4

sec Ф  = 1/ cosФ  =  10/6 or 5/3

csc Ф  = 1 / sin Ф = 10/8 or 5/4
