No, because it has a constant rate of change

By looking at this table

The y value changes at a constant multiple of 2

6 4

7 2 (4-2 is a difference of 2)

8 0 (2-0 is a difference of 2)

9 -2 (0-2 is a difference of 2)

This means it is Linear

No, because it has a constant rate of charge.

Rate of change of function: $\dfrac{y_2-y_1}{x_2-x_1}$

$\begin{array}{ccc}6\to4\\7\to2\end{array}\Rightarrow\dfrac{2-4}{7-6}=\dfrac{-2}{1}=-2\\\\\begin{array}{ccc}7\to2\\8\to0\end{array}\Rightarrow\dfrac{0-2}{8-7}=\dfrac{-2}{1}=-2\\\\\begin{array}{ccc}8\to0\\9\to-2\end{array}\Rightarrow\dfrac{-2-0}{9-8}=\dfrac{-2}{1}=-2\\\\$

Find the measure of the exterior angle.

Illusion [34]

Answer:

108 degrees

Step-by-step explanation:

From the diagram we are given

Interior angles are 2x + 1 and 63 degrees

Exterior angle = 5x -2

The sum of interior angles is equal to the exterior angle

2x + 1 + 63 = 5x - 2

2x + 64 = 5x - 2

2x - 5x = -2-64

-3x = -66

x = -66/-3

x = 22

Get the exterior angle:

Exterior angle = 5x-2

Exterior angle = 5(22) - 2

Exterior angle = 110-2

Exterior angle = 108 degrees

Hence the measure of the exterior angle is 108 degrees

About 8% of the U.S. population catches the flu each season. Assuming everyone has equal probability of catching the flu, about

avanturin [10]

Answer:

The odds are 2 : 23, or about 0.09 : 1 (0.09 to 1).

Explanation:

The odds of an event is the ratio of occurrence to non-occurrence of the event.

When you know the probability of an event, then you can calculate the odds by dividing the probability of occurence by the probability of non-occurrence.

Calling p the probability that an event will happen, 1 - p is the probability that it will not happen and the odds will be:

Odds = p / ( 1 - p)

You have p = 8% = 0.08, and 1 - p = 1 -0.08 = 0.92.

Therefore:

Odds = 0.08 / 0.92 = 8 : 92 = 2 : 23 ≈ 0.09 : 1 (0.09 to 1)

Two cables support a 800-lb weight, as shown. Find the tension in each cable.

jeka94

Answer:

892 lb (right)
653 lb (left)

Step-by-step explanation:

The weight is in equilibrium, so the net force on it is zero. If R and L represent the tensions in the Right and Left cables, respectively ...

Rcos(45°) +Lcos(75°) = 800

Rsin(45°) -Lsin(75°) = 0

Solving these equations by Cramer's Rule, we get ...

R = 800sin(75°)/(cos(75°)sin(45°) +cos(45°)sin(75°))

= 800sin(75°)/sin(120°) ≈ 892 . . . pounds

L = 800sin(45°)/sin(120°) ≈ 653 . . . pounds

The tension in the right cable is about 892 pounds; about 653 pounds in the left cable.

_____

This suggests a really simple generic solution. For angle α on the right and β on the left and weight w, the tensions (right, left) are ...

(right, left) = w/sin(α+β)×(sin(β), sin(α))
