The situation that can be modeled by a linear function is:

An amusement park allows 50 people every 30 minutes

Option 3 is the correct answer.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

A linear function is a function in the form of f(x) = mx + c.

Now,

1)

The population of bacteria triples every day.

This can be written as a function,

f(x) = M x [tex]3^x[/tex]

Where M is the initial number of bacteria and x is the number of days.

This is an exponential function.

2)

The value of cell phones depreciates at a rate of 3.5% each year.

This can be written as a function,

f(x) = M x [tex]96.5^x[/tex]

Where M is the initial value and x is the number of years.

This is an exponential function.

3)

An amusement park allows 50 people every 30 minutes.

This can be written as a function,

f(x) = 50x

Where x is the number of times of 30 minutes.

This is a linear function.

4)

A baseball tournament eliminates half of its teams after each round.

This can be written as a function,

f(x) = M x [tex](1/2)^x[/tex]

Where x is the number of rounds.

This is an exponential function.

Thus,

An amusement park allows 50 people every 30 minutes can be modeled by a linear function.

Answer: To determine if a set of dimensions is possible for the container, we need to check if it satisfies both the inequality h > 0.3r^2 and the two constraints.

A) radius = 21 inches, height = 21 inches:

The inequality h > 0.3r^2 is satisfied (21 > 0.3 * 21^2).

The height must be no more than 15 inches greater than the radius (21 - 21 <= 15), which is satisfied.

The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is not satisfied (pi * 21^2 < 36pi).

So, option A is not a possible set of dimensions.

B) radius = 8 inches, height = 21 inches:

The inequality h > 0.3r^2 is satisfied (21 > 0.3 * 8^2).

The height must be no more than 15 inches greater than the radius (21 - 8 <= 15), which is satisfied.

The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is satisfied (pi * 8^2 >= 36pi).

So, option B is a possible set of dimensions.

C) radius = 7 inches, height = 23 inches:

The inequality h > 0.3r^2 is satisfied (23 > 0.3 * 7^2).

The height must be no more than 15 inches greater than the radius (23 - 7 <= 15), which is satisfied.

The area of the base must be at least 36pi square inches (pi * r^2 >= 36pi), which is not satisfied (pi * 7^2 < 36pi).

So, option C is not a possible set of dimensions.

D) radius = 9 inches, height = 18 inches:

The inequality h > 0.3r^2 is not satisfied (18 <= 0.3 * 9^2).

The height must be no more than 15 inches greater than the radius (18 - 9 <= 15), which is not satisfied.

So, option D is not a possible set of dimensions.

Therefore, the only possible set of dimensions is B) radius = 8 inches, height = 21 inches.

Answer:

Answer:

showed below

Explanation:

you can start by plotting a dot at (2,0), since the line must go through that point. Since m, the slope, is -2, you can re-write this into a fraction to make it easier, looking like this: -2/1. Slope in general can be written as “rise over run” or “rise/run”, so the numerator is how far you go up on the graph, while the denominator is how far you go over. In this case, the slope is negative, so instead of up and right, the line goes down and right. From (2,0) you would go down by 2, and right by one. At that point you polar another dot. That point is (3,-2). From there, you can take a straight edge and line it up with the two dots and draw your line. It looks like what is in the picture.

Since the corresponding sides are not proportional, we can say that the triangles are not similar

In similar triangles, corresponding sides are always in the same ratio.

Given are two triangles ΔWUV and ΔXZY.

It is given that -

VW = 60     ZY = 48     YX = 40     VU = 50     UW = 40     XZ = 32

For the triangles to be similar, the corresponding sides will be proportional.

WU/XZ = UV/ZY = WV/XY

40/32 = 50/48 = 60/40

1.25 ≠ 1.044 ≠ 1.5

The corresponding sides are not proportional.

Therefore, since the corresponding sides are not proportional, we can say that the triangles are not similar.

Step-by-step explanation:

The value of h(x) = 0 gives x=5.

In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the b. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.

Given:

h(x) = -x + 5

So, for h(x)= 0 we have

-x + 5= 0

now, solving for x

-x = -5

x= 5

200 number of students brought their lunch to school on Thursday.

A Percentage is a number or ratio that can be expressed as a fraction of 100.

To determine the percentage, we have to divide the value by the total value and then multiply the resultant by 100.

Percentage formula = (Value/Total Value) × 100

P% of Number = X

where X is the required percentage.

If we remove the % sign, we need to express the above formula

P/100 × Number = X

Given:

Total number of students in school = 800

25% students bring their lunch every day.

25% of 800

Answer: Let's call the hourly rate for regular work as "r" and the hourly rate for overtime work as "o".

From the information given, we know that 80 hours of regular work earned Andrew 80 * r = $920.65.

And we also know that 5 hours of overtime work earned him 5 * o = $109.80.

So, combining the two amounts, we have:

80 * r + 5 * o = $1030.45

Now, we can substitute the first equation into the second:

80 * r + 5 * o = $1030.45

80 * r = $920.65

80 * r + 5 * o = $1030.45

5 * o = $1030.45 - $920.65

5 * o = $109.80

Finally, we can solve for the hourly rate of overtime work:

o = $109.80 / 5

o = $21.96/hour

According to the table, the values of g(x) are 2 units lower than the corresponding values of f(x).

Translation of functions

When a function is transferred without undergoing any form or rotation changes, it has been "translated." A function may be translated both horizontally and vertically.

According to the question;

The table that illustrates function g(x) is; when the function f(x) is shifted vertically down by 2 units to obtain function g

x = 0, 1, 2, 3

g(x) = -2, 0, 6, 24

By shifting the function f vertically down by 2 units, the function g(x) is produced.

Note that the relationship between the functions g and f is as follows:

g(x) = f(x) -2

Therefore, as seen in the above table, the values of g(x) are 2 units fewer than the corresponding values of f(x).
