Match each trigonometric function with its Unit Circle definition. Note that Angle A is correctly oriented for the Unit Circle d
PtichkaEL [24]
The first diagram below shows a circle with a radius of 1 (unit circle). The circle is drawn on a Cartesian graph with (0,0) as the center of the circle.

From the second diagram, we can determine the value of sin(Θ) = y
and cos(Θ) = x

We can further deduce that
tan(Θ) = \frac{y}{x}
sec(Θ) = \frac{1}{cos(Θ)} = \frac{1}{x}
cosec(Θ) = \frac{1}{sin(Θ)} = \frac{1}{y}
cot(Θ) = \frac{cos(Θ)}{sin(Θ)} = \frac{x}{y}

Which transformation have been preformed on a graph of f(x)=x2 to obtained the graph of g(x) =-3(x+1)2-4?
avanturin [10]

Horizontal shift because g(x)=f(x+1) 1 unit left

Vertical shift because g(x)=f(x+1)-4 4 units down

Reflected across x-axis because g(x)=-f(x)

Vertically stretched because g(x)=3(f(x))

Step-by-step explanation:

We need to identify which transformation have been preformed on a graph of f(x)=x2 to obtained the graph of g(x) =-3(x+1)2-4?

Rules for transformation:

Horizontal shift: depends on the value h

if g(x)=f(x+h) then: the graph is shifted left h units

if g(x)=f(x-h) then: the graph is shifted right h units

Vertical Shift: depends on the value k

if g(x)=f(x)+k then: the graph is shifted up k units

if g(x)=f(x)-k then: the graph is shifted down k units

Reflection:

if g(x)=-f(x) then graph is reflected at x-axis

if g(x)=f(-x) then graph is reflected at y-axis

Vertical Stretch:

if g(x)=c.f(x) then graph is vertically stretched.

In the given question:

f(x)= x^2

g(x)=-3(x+1)^2-4

Applying the above rules of transformation:

The graph is:

Horizontal shift because g(x)=f(x+1) 1 unit left

Vertical shift because g(x)=f(x+1)-4 4 units down

Reflected across x-axis because g(x)=-f(x)

Vertically stretched because g(x)=3(f(x))

SOMEONE HELP ME FIND THE Y PLEASE ASAP
Evgesh-ka [11]

Answer:

(Down Below)

Step-by-step explanation:

Plug in the value of x in the left column for all the values in the equation. I will do a couple for you.

Since -4 is the value of x, substitute it into the equation for x.

y= -4-5=-9

-1

y=-1-5=-6

0

y=0-5=-5

You can do the rest. You got this! Comment if you need more help!

If angle P measures 50 degrees, what is the measure of angle Q?
dolphi86 [110]

Answer:

130 degrees

Step-by-step explanation:

Since angles P and Q are supplementary (meaning that they add up to 180), we can set up the equation:

180 = 50 + Q

Q = 130
