W hich of the following are you not likely to see on a graph? dependent variable, units, independent variable, prediction ...?

Answers

Answer: Fourth option is correct.

Step-by-step explanation:

On graph, we can display dependent variables, units, independent variables , because they can be expressed in numbers easily.

Whereas prediction is not competent every time to get expressed with numerical terms.

Hence, prediction is not likely to see on the graph.

Thus, Fourth option is correct.

A company introduces a new product for which the number of units sold S is
S(t)= 200 ( 5- 9/(2+t))
where t is the time in months

(a) Find the avg. value of S(t) during the first year.
(b) During what month does S'(t) equal the avg value during the first year? ...?

Answers

(a) The "average value" of a function over an interval [a,b] is defined to be

(1/(b-a)) times the integral of f from the limits x= a to x = b.

Now S = 200(5 - 9/(2+t))

The average value of S during the first year (from t = 0 months to t = 12 months) is then:

(1/12) times the integral of 200(5 - 9/(2+t)) from t = 0 to t = 12

or 200/12 times the integral of (5 - 9/(2+t)) from t= 0 to t = 12

This equals 200/12 * (5t -9ln(2+t))

Evaluating this with the limits t= 0 to t = 12 gives:

708.113 units., which is the average value of S(t) during the first year.

(b). We need to find S'(t), and then equate this with the average value.

Now S'(t) = 1800/(t+2)^2

So you're left with solving 1800/(t+2)^2 = 708.113

I'll leave that to you

c) In how many ways can I choose three seniors to represent the group?
d) In how many ways can I choose four seniors to represent the group?
e) In how many ways can I choose five seniors to represent the group?

Answers

a) The answer is 5.

nCr = n! / (r! (n - r)!)
n - number of things to be chosen from
r - number of chosen things

There are five seniors in a class: n = 5
I choose one senior: r = 1

nCr = n! / (r! (n - r)!)
5C1 = 5! / (1! (5 - 1)!)
= (5 * 4 * 3 * 2 * 1) / (1 * 4!)
= 120 / (4 * 3 * 2 * 1)
= 120 / 24
= 5

b) The answer is 10.

nCr = n! / (r! (n - r)!)
n - number of things to be chosen from
r - number of chosen things

There are five seniors in a class: n = 5
I choose two seniors: r = 2

nCr = n! / (r! (n - r)!)
5C2 = 5! / (2! (5 - 2)!)
= (5 * 4 * 3 * 2 * 1) / ((2 * 1) * 3!)
= 120 / (2 * (3 * 2 * 1))
= 120 / (2 * 6)
= 120 / 12
= 10

c) The answer is 10.

nCr = n! / (r! (n - r)!)
n - number of things to be chosen from
r - number of chosen things

There are five seniors in a class: n = 5
I choose three seniors: r = 3

nCr = n! / (r! (n - r)!)
5C3 = 5! / (3! (5 - 3)!)
= (5 * 4 * 3 * 2 * 1) / ((3 * 2 * 1) * 2!)
= 120 / (6 * (2 * 1))
= 120 / (6 * 2)
= 120 / 12
= 10

d) The answer is 5.

nCr = n! / (r! (n - r)!)
n - number of things to be chosen from
r - number of chosen things

There are five seniors in a class: n = 5
I choose four seniors: r = 4

nCr = n! / (r! (n - r)!)
5C4 = 5! / (4! (5 - 4)!)
= (5 * 4 * 3 * 2 * 1) / ((4 * 3 * 2 * 1) * 1!)
= 120 / (24 * 1)
= 120 / 24
= 5

e) The answer is 1.

nCr = n! / (r! (n - r)!)
n - number of things to be chosen from
r - number of chosen things

There are five seniors in a class: n = 5
I choose five seniors: r = 5

nCr = n! / (r! (n - r)!)
5C5 = 5! / (5! (5 - 5)!)
= (5 * 4 * 3 * 2 * 1) / ((5 * 4 * 3 * 2 * 1) * 1!)

A rectangle's length is 4 feet more than its width. If the area of the rectangle is 396 square feet, what is its width, in feet?

Answers

the width of the rectangle is 18 feet (and the length is 22 ft)

Let the length be l and width be w.
l = w + 4

Area = length x width
396 = (w + 4)w
w² + 4w - 396 = 0
w = 18, w = -22
Negative width not possible so answer discarded.

Width = 18 feet.

[tex]y =-\frac{1}{4}x+10[/tex]

Step-by-step explanation:

Slope intercept form:

The equation of line is given by:

[tex]y=mx+c[/tex] .....[1]

where, m is the rate or slope and c is the y-intercept or initial value.

As per the statement:

Here, y represents the distance in kilometer and x represents the time in minutes.

A student is running a 10-kilometer race

⇒y(0) = b = 10 km

It is also given that he runs 1 kilometer every 4 minutes.

Now, with each passing minute the student is getting closer and closer to the finish line which was 10 kilometers away when the race started. Thus, as the race progresses, the distance between the student and the finish line will decrease.

[tex]m =-\frac{1}{4}[/tex]

Substitute these in [1] we have;

[tex]y = -\frac{1}{4}x+10[/tex]

Therefore, the function that describes his distance from the finish line is, [tex]y = -\frac{1}{4}x+10[/tex]

Select all ratios equivalent to 20:4
4:20, 2:10, 15:3, 1:2

Answers

15:3 is the only equivalent ratio to 20:4.

Final answer:

The only ratio equivalent to 20:4 from the given choices is 15:3 because, when simplified, both ratios reduce to 5:1.

Explanation:

To determine which ratios are equivalent to 20:4, we need to find ratios that can be simplified or scaled to form the same relationship. An equivalent ratio maintains the proportion when both terms are multiplied or divided by the same number.

First, the given ratio of 20:4 can be simplified by dividing both terms by 4, which gives us 5:1. Now, we can compare this to the choices provided:

4:20 is not equivalent because when simplified (divided by 4), it gives 1:5, which is the inverse of 5:1.2:10 simplifies to 1:5 (dividing by 2), also not equivalent for the same reason.15:3 simplifies to 5:1 (dividing both terms by 3), which is equivalent to 20:4.1:2 is already in simplest form and is not equivalent to 5:1 or 20:4.

Therefore, the only ratio equivalent to 20:4 given in the choices is 15:3.

We have to determine

What can be said about the length of the third side?

According to the question

The lengths of the two sides of a triangle are 9 and 15.

By the properties of the triangle, the sum of the square of two lengths is equal to the third side length of the triangle.

Always remember that when you add two sides to a triangle, the sum will come out to be higher than the third side’s length.

Hence, It must be greater than or equal to 6 and at most 24.

Egypt is 386,700 square miles and wyoming is about 97,818 square miles egypt is about how many times as large as wyoming

Answers

To solve this problem, we need to divide 386,700 by 97,818 to see how many times you need to multiply 97,818 to get 386,700; after doing this, we can see that Egypt is about 3.95 times larger than Wyoming.

Final answer:

Egypt is approximately 4 times as large as Wyoming when comparing their areas.

Explanation:

To calculate how many times larger Egypt is compared to Wyoming, we divide the area of Egypt by the area of Wyoming. The area of Egypt is 386,700 square miles, and the area of Wyoming is about 97,818 square miles.

Dividing the area of Egypt by the area of Wyoming gives us: 386,700 / 97,818 ≈ 3.95.

What is the difference between slope on a table and slope on a graph

Answers

On a table there is no way you could calcualte rise over run, but other than that they are veryyyyyy similar

The difference between slope on a table and slope on a graph is shown below:

The slope on a table refers to the rate of change between two points represented in a table of values.

It is calculated by finding the ratio of the change in y-values to the change in x-values between two points.

The slope on a table is determined by taking the difference in y-values and dividing it by the difference in x-values.

On the other hand, the slope on a graph refers to the steepness or incline of a line that connects two points on a graph.

It is calculated by the ratio of the vertical change (rise) to the horizontal change (run) between two points on the graph.

While both the slope on a table and the slope on a graph represent the rate of change, they are determined differently.

Given that f(x) = 6x 2 and g(x) =2x=4/5 , solve for g(f(1))

Answers

Answer:

The answer would be 4.

Step-by-step explanation:

What you have to do here is you have to substitute

So the problem told you the f(x) = 1. So what you want to do is plug that into the function f(x).

So:

f(x) = 6(1)2

= 8

Now we know that f(x) = 8, so what we going to do now is plug f(x) into g(x).

So:

g(f(8)) = 2(8) + 4/5

= 4

The value of g(f(1)) is 4.

Composite function -Composition of functions is the process of plugging one function into another, and simplifying or evaluating the result at a given x-value. Another way to read it is "f circle g of x." It is a process that joins two functions to create a third, unique function.

Given ,

f(x) = 6x + 2

g (x) = 2x + 4 /5

To get value of g(f(1)) first we have to solve f(x).

f(x) = 6x + 2 .......................(1)

We simply put x = 1 in equation 1 .

Then, F(1) = 6 × 1 + 2 ⇒ 8

Now , we put value of f(1) in g(f(1)) ,

So, g(f(1)) = [tex]\frac{2x + 4}{5}[/tex]

= [tex]\frac{2 * 8 + 4}{5}[/tex]

= [tex]\frac{16 + 4}{5}[/tex]

= 20/5 ⇒ 4

Therefore, the value of g(f(1)) is 4 .
