Answer:

2(-2-8)

Step-by-step explanation:

The difference between -2 and 8 is -2-8. The product of 2 and the difference is (-2-8)*2 which is 2(-2-8).

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.

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

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]

5 × -8 × 2

= - 40 x 2

= - 80

Answer:

-80

Step-by-step explanation:

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.

The the rectangular solid with maximum volume for given surface area is, in fact, a cube with side 4.5.

Which formula represents the volume of a rectangular prism?

Let x = the side of the square base and y = height

Let V = volume = x2y

The surface area = 2x2 + 4xy = 121.5

Solve the surface area equation for y = (121.5 - 2x2)/4x and substitute this into the volume equation

V = x2(121.5 - 2x2)/4x = x(121.5 - 2x2)/4

the derivative of V with respect to x = (x/4)(-2x) + (1/4)(121.5 - 2x2) = 0 at the maximum

(1/4)(-4x2 + 121.5 - 2x2) = 0'

6x2 = 121.5

x2 = 20.25

x = 4.5

y = (121.5 - 40.5)/(4 * 4.5) =81/18 = 4.5

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 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
