Does the figure above appear to have rotational symmetry?if yes, select the angles of rotation less than 360°

0.45  is the probability someone who studies very hard for the bar passe.

What is probability?

Odds of passing = 1.22  = p ( passing)/ P(not passing)

P(Pass)/P( fail)  = 1.22

p (pass) = 1.22 p (fail)

P(pass) + P(fail) = 1

1.22 p (fail) + p(fail) = 1

2.22 p(fail) = 1

P (fail) = 0.4505   ≅ 0.45

The equation of the parabola that models the given situation is y=-1/6 (x-3)^2 +1.5.

Define parabola and its types.

A parabola is a roughly U-shaped mirror-symmetrical plane curve. It corresponds to a number of seemingly unrelated mathematical descriptions that all define the same curves.

To represent a parabola algebraically in the coordinate plane, the standard equation of a parabola is used. The general equation of the parabola is given by [tex]$\mathrm{y}=a(x-h)^2+\mathrm{k}$[/tex]or [tex]$\mathrm{x}=a(y-k)^2+\mathrm{h}$[/tex], where [tex]$(\mathrm{h}, \mathrm{k})$[/tex] denotes the vertex. A regular parabola's standard equation is y^2= 4ax

Now, the equation of parabola for the given situation is calculated as:

y=a(x-3)^2 +1.5

Now, put the value of x=0 and y=0.

0=a(0-3)^2+1.5

0=9 a+1.5

-9 a=1.5

a=-1.5 / 9

a=-1 / 6

Now, put the value of a in equation[tex]$\mathrm{y}=a(x-3)^2+1.5$[/tex] to obtain:

y=-1/6 (x-3)^2 +1.5

if the terminal point indicated by t is in the provided quadrant, the first equation in terms of the second quadrant iv; cos(t), sin(t). [tex]\sin t=\sqrt{1-\frac{1}{\sec ^2 t}}[/tex]

Trig identities come in handy when we need to express one trig function in terms of another. The most famous trig identity is derived straight from the Pythagorean Theorem:

sin² t +  cos² t = 1

For an angle t in Quadrant IV, we know sin t is positive.

From the trig identity sin² t +  cos² t = 1

we can also write as:

sin t + cos t:

Now,

sin² t + cos² t = 1

sin² t   = 1 -  cos² t

sin t = ±√( 1 -  cos² t)

As noted above,

sin t is positive for t in the Quadrant IV, and so we have

sin t = √( 1 -  cos² t)

We know that

[tex]\cos t=\frac{1}{\sec t}[/tex]

So, the equation will be

[tex]\sin t=\sqrt{1-\frac{1}{\sec ^2 t}}[/tex]

The true statements regarding this situation are as follows:

The diagram is missing, but it is given on the graph at the end of the answer. (not drawn to scale)

The alternate interior angles are between the two parallel lines, one in each side, and they are congruent.

Hence:

Angles 3 and 6 are congruent because they are alternate interior angles.

Straight angles are angles of 180º on a line, hence:

Angles 1 and 3 add to 180º as they are straight angles.

Since angles 3 and 6 are congruent(alternate interior), angles 1 and 6 will also be supplementary, as they add to 180º.

The point at 1/5 of the coordinate points is (-11/5, -7/5)

The coordinates are given as:

(-3, -2) to (1, 1)?

The location 1/5 can be represented as

m : n = 1 : 4

The location of the point is then calculated as:

P = 1/5 * (mx2 + nx1, my2 + ny1)

This gives

P = 1/5 * (1 * 1 + 4 * -3, 1 * 1 + 4 * -2)

Evaluate

P = 1/5 * (-11, -7)

This gives

P = (-11/5, -7/5)

Hence, the point at 1/5 of the coordinate points is (-11/5, -7/5)

Answer:

A.  {-4, 2, 3, 8}

Step-by-step explanation:

The range of a function is the set of all possible output values (y-values).

From inspection of the graph, the coordinates of the points are:

Therefore, the set of y-values is {-4, 2, 3, 8}.  This is the range of the graphed function.

The equation of the line in point-slope form is: y - 5 = -x + 2.

The equation of the line can be modelled as y - b = m(x - a), in point-slope form..

Given the following:

(2, 5) and (-1, 8), find the slope

Slope of the line (m) = change in y / change in x = (8 - 5)/(-1 - 2)

Slope of the line (m) = 3/-3

Slope of the line (m) = -1

Substitute (a, b) = (2, 5) and m = -1 into y - b = m(x - a):

y - 5 = -1(x - 2)

y - 5 = -x + 2

Therefore, the equation of the line in point-slope form is: y - 5 = -x + 2.
