what is the average rate of change of the population between 1930 and 1950? show your reasoning?

Answers

Answer 1

Answer:

The average rate of change is: 0.25

Step-by-step explanation:

Given

See attachment for graph

Required

The average rate of change between 1930 and 1950

Average rate of change (m) is calculated as:

[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]

In this case,

[tex][a,b] = [1930,1950][/tex]

So, we have:

[tex]m = \frac{f(1950) - f(1930)}{1950 - 1930}[/tex]

[tex]m = \frac{f(1950) - f(1930)}{20}[/tex]

From the attached graph;

[tex]f(1950) = 45[/tex]

[tex]f(1930) = 40[/tex]

So, we have:

[tex]m = \frac{45- 40}{20}[/tex]

[tex]m = \frac{5}{20}[/tex]

[tex]m = 0.25[/tex]

5x -6y=-32



3x+6y=48


solve using elimination, i have a bunch of these i need to get done

Answers

So this question is already perfectly set up. Since the 6 and -6 cancel you’ll be left with 5x + 3x which is 8x and -32 + 48 which is 16. 8x=16. Isolate x to get that x=2. Plug 2 back into one of the equations. 5(2) -6y = -32. Solve for y now. -10-32 equals -42. Divide -42 by -6 to get 7. So the final coordinate where the two equations will intersect is (2,7)

The clock one is 20 because there are 4 weeks past and you would just plug that into the equation. The catering one is 118 , also plugging into the equation given.

Answer:

The first question provided (question 11)

The answer is $118.00

The second question provided (question 12)

The answer is 20 seconds

Step-by-step explanation:

The first question provided (question 11)

The equation 5a + 3c is provided to determine the cost of a catering event, where a is the number of adults and c is the number of children.

It is stated that there are 17 adults and 11 children attending an event.

You can substitute in the 17 adults in place of a and the 11 children in place of c.

This will leave you with 5(17) + 3(11).

If you simplify you will get 85 + 33, which is equal to 118

Therefore, the answer is $118.00.

The second question provided (question 12)

The equation s = 5w is provided to determine how far behind a clock is after a certain amount of time, where s is seconds behind and w is the number of weeks sice the clock was last set.

You are given the clock was set 4 weeks ago.

You can subsitute the 4 weeks into the equation in place of variable w.

This leaves you with s = 5(4).

Simplifying this further, you will get s = 20.

Therefore, the clock is 20 seconds behind.

Jalen is trying to set a pole that is 10 ft long into the ground so that it is perpendicular with the horizontal surface. Jalen locates a point 6 feet from the base of the pole, at C, and labels it A then he measures the distance from point a to b what distance to the nearest tenth of a foot does haley need for the pole to be perpendicular

Answers

Answer:

The distance from point A to B that Haley needs for the pole to be perpendicular is:

11.66 feet.

Step-by-step explanation:

To solve this exercise, imagine that it is a triangle, where the height is the pole, which is 10 feet, and the base of the triangle is the distance between the base of the pole and the point located by Jalen and called C, which it would have a measurement of 6 feet, finally, the measurement between A (the point located six feet) and B (the highest part of the pole) would correspond to the hypotenuse of a triangle,

Therefore, having these two measures, you could use the Pythagorean theorem to find the hypotenuse of a triangle with those measures and solve it, remember that the Pythagorean theorem is:

Hypotenuse^2 = opposite leg^2 + adjacent leg^2

We replace the values given in the exercise:

Hypotenuse^2 = (10 ft)^2 + (6 ft)^2Hypotenuse^2 = 100 ft^2 + 36 ft^2[tex]\sqrt{hypotenuse^{2} }[/tex] = [tex]\sqrt{100 ft^{2} +36ft^{2} }[/tex]Hypotenuse = [tex]\sqrt{136ft^{2} }[/tex]Hypotenuse = 11.66 ft approximately.

In this form, Jalen can be sure the pole is perpendicular to the ground when the distance from point A to B is 11.66 ft approximately.
