Andreas93 [3]3 years ago
6 0

Answer:

x = 81/7

Step-by-step explanation:

3(2x - 14) = -3(-13 + x)

6x - 42 = 39 - x

6x + x = 39 + 42

7x = 81

x = 81 ÷ 7

x = 81/7

How do you find the sine, cosine, and tangent values on the unit circle not in the first quadrant? Provide an example, and how y
gizmo_the_mogwai [7]
A point (-0.8, 0.6) will be a point on the unit circle in the second quadrant. Since it is a unit circle, its radius is 1, and we have
  sin(α) = y = 0.6
  cos(α) = x = -0.8
  tan(α) = y/x = 0.6/-0.8 = -0.75

The angle is α = arccos(-0.8) ≈ 143.13°

______
For the unit circle, the trig values are always the coordinates or their ratio as shown above, regardless of quadrant.

Given that events A and B are independent with P(A)=0.3P(A)=0.3 and P(A\cap B)=0.27P(A∩B)=0.27, determine the value of P(B)P(B),
Stolb23 [73]

Answer:

0.9

Step-by-step explanation:

Since A and B are independent  hence;

P(A∩B) = P(A)P(B)

Given the following

P(A∩B) = 0.27

P(A) = 0.3

Required

P(B)

Substitute into the formula;

P(B) = P(A∩B)/P(A)

P(B) = 0.27/0.3

P(B) = 0.9

Hence the value of P(B) is 0.9

Which of the following is a valid comparison between the possible minimum and maximum values of the function y = -x2 + 4x - 8 an
Arturiano [62]

Answer:

The maximum value of the equation is 1 less than the maximum value of the graph

Step-by-step explanation:

We have the equation y=-x^2+4x-8.

We can know that this graph will have a maximum value as this is a negative parabola.

In order to find the maximum value, we can use the equation x=\frac{-b}{2a}

In our given equation:

a=-1

b=4

c=-8

Now we can plug in these values to the equation

x=\frac{-4}{-2} \\\\x=2

Now we can plug the x value where the maximum occurs to find the max value of the equation

y=-(2)^2+4(2)-8\\\\y=-4+8-8\\\\y=-4

This means that the maximum of this equation is -4.

The maximum of the graph is shown to be -3

This means that the maximum value of the equation is 1 less than the maximum value of the graph

Find the slope of the line passing through the points (-7, -7) and (-3, 6).
Alenkasestr [34]

Answer:

13/4 - (13,4) - however your teacher wants you to write it out.

Step-by-step explanation:

Rise (y) over Run (x)

Equation:

y2 - y1

over

x2 - x1

Inputting the numbers, 6 - -7 (aka 6+7) over -3 - -7 (aka -3+7)

6+7 = 13

-3+7 = 4

13/4 - The line is rising moving towards the right.

Hope I helped!
