what is a rational number between 9.6 and 9.7

Answers

The rational number between them is 9.6 1/2

A rational number between 9.6 and 9.7 is 93/20.

The given decimal numbers are 9.6 and 9.7.

What are the rational numbers?

Rational numbers are in the form of p/q, where p and q can be any integer and q ≠ 0. This means that rational numbers include natural numbers, whole numbers, integers, fractions of integers, and decimals (terminating decimals and recurring decimals).

Now, (9.6+9.7)/2

= 19.3/2

= 9.65

So, the rational number is 965/100 = 93/20

Therefore, a rational number between 9.6 and 9.7 is 93/20.

Dam is rowing a boat away from a dock the graph shows the relationship between the time and sams distance from the dock. Evaluate the function for an input of 9

Answers

The answer is B.

A and C would not be correct because you are finding the distance for 9 minutes. D is not correct because the y-axis does not even have 3 meters on it, neither does the graph hit y=3.

Answer:

B. After 9 minutes Sam is 80 meters away from the dock.

Step-by-step explanation:

We have been given a graph of function that shows the relationship between the time and Sam's distance from the dock.

Let us see our given options one by one to find the correct choice.

A. After 80 minutes Sam is 9 meters away from the dock.

Upon looking at our graph we can see that y-axis is representing distance in meters and x-axis is representing time in minutes. Range of x is from 0 to 11 So our input cannot be greater than 11.    

Therefore, option A is not a correct choice.

B. After 9 minutes Sam is 80 meters away from the dock.

We can clearly see from our given graph that at 9 minutes distance is 80 meters, which means that after 9 minutes Sam is 80 meters away from the dock. Therefore, option B is the correct choice.

C. After 80 minutes Sam is 80 meters away from the dock.

We can see from our graph that range of x is from 0 to 11 minutes, So our input can not be greater than 11. Therefore, option C is not a correct choice.  

D. After 9 minutes Sam is 3 meters away from the dock.

We can see from our graph that initial value of our function is 20, which means that at time equals 0 minutes Sam was 20 meters away from dock and this distance is increasing with the time. Therefore, option D is not a correct choice.

What is rectangular pyramid ?

A rectangular pyramid is a 3-D object with a base shaped like a rectangle and triangle-shaped faces or sides that correspond to each side of the base. Like the other types of pyramids, a rectangular pyramid also has a point on top of the base of the pyramid that is joined together by bringing the top of all the sides which is known as the apx. A rectangular pyramid has a total of 5 faces, 5 vertices, and 8 edges and is of two types a right pyramid or an oblique pyramid.  

According to the question

Part A: A cross section of the rectangular pyramid is cut with a plane parallel to the base.

When we cut a cross section parallel to base of the rectangular pyramid which have rectangular base

The cross section will always be a rectangle.  

Part B: If a cross section of the rectangular pyramid is cut perpendicular to the base, passing through the top vertex .

When we cut a cross section perpendicular to the base, passing through the top vertex of the rectangular pyramid

The cross section will always be a Triangle.  

As the lateral face of a rectangular pyramid  is a triangle, so a cross section that passes through the top vertex and the base is also a triangle.

Hence , The Part A cross section will be rectangle and Part B cross section will be triangle .

If a train is moving 72 km/h on a road of 360 km, how much time will it take to arrive?

Answers

It should 5 hours. You do 360 divided by 72 and get 5 
"I'm assuming this is just a rate problem not a more complex physics answer. Think about it this way:

72 kilometers is 72,000 meters, and an hour is 60 minutes of 60 seconds each, meaning an hour is 3600 seconds (60m*60s). This means that in 3600 seconds the car travels 72,000 meters. You can figure out how many meters are travelled per second by dividing 72,000 meters by 3,600 seconds, giving you 20 meters per second. This would give you an answer of 80 meters in 4 seconds, not 120 m. I don't know how to account for that disparity, but 80 meters would be the correct answer. If there is any other information in the problem it is probably important."

Find the vertex of the given function.
f(x) = l x-5 l + 10
The vertex is at (___, ___)

Answers

when it comes to this "vertex form" type of expressions, the cheap way to get the vertex is, set the grouped terms to 0, namely

x - 5 = 0
x = 5

well, if we set x = 5, x - 5, turns to 0, and that happens when x  = 5, therefore, the vertex is

| x - 5 | + 10

| (5) - 5 |  (+ 10)              is at ( 5 , 10 )

The vertex of an absolute function is the highest or lowest point of the function. The vertex of the given equation is: (5,10)

Given that:

[tex]f(x) = |x - 5|+ 10[/tex]

If an absolute function is represented as:

[tex]f(x) = a|x - h|+ k[/tex]

The vertex of the function is:

[tex]Vertex = (h,k)[/tex]

By comparing [tex]f(x) = a|x - h|+ k[/tex] and [tex]f(x) = |x - 5|+ 10[/tex]

[tex]h = 5[/tex]

[tex]k =10[/tex]

If g(x) and f(x) are inverse functions, which graph represents g(x)?
A. 2nd Graph below
B. 3rd Graph below
C. 4th Graph below
D. 5th Graph below

Answers

The 1st graph shows a radical expression, where:
[tex]f(x) = \sqrt{x} [/tex]
to find the inverse, replace f(x) with y, switch the x and the y, then solve for y
[tex]f(x) = \sqrt{x} ... \: y = \sqrt{x} \\ x = \sqrt{y} \\ {( \sqrt{y})}^{2} = {x}^{2} \\ y = g(x) = {x}^{2} [/tex]
The only graph showing exponential growth is the 2nd graph (note how at 1 it's 1, at 2 it's 4, at 3 it will be 9, etc.)

Given that we have the graph of f(x), we want to see which one is the graph of its inverse. The correct option is B, the third graph.

Remember that two functions f(x) and g(x) are inverses if:

f(g(x)) = g(f(x)) = x

This also means that if:

f(x) = y

then g(y) = x.

So we basically should have the exact same graph of f(x), but we just "interchange" the two axes.

From this, we can see that the correct option is the third graph (the one where the curve goes upwards. So the correct option is B.

Compare how you would model and record finding the sum difference of two rocks weighing 2/8 pound and 3/8 pound.

Answers

2/8+3/8=5/8

3/8-2/8=1/8

hope this helped

Final answer:

To find the sum or difference of two rocks weighing 2/8 pound and 3/8 pound, add or subtract their numerators while keeping the denominator the same. The sum is 5/8 pound, and if finding a difference with the second rock being lighter, it's 1/8 pound.

Explanation:

To model the sum of two rocks weighing 2/8 pound and 3/8 pound, we work with fractions with the same denominator. To find the sum, simply add the numerators together and keep the same denominator. Thus, 2/8 + 3/8 equals 5/8. To record the sum difference, you list both weights then show their combined weight, which is the sum.

The process is like this:

Write down the weights of the two rocks: 2/8 pound and 3/8 pound.Add the numerators (2 + 3 = 5) while keeping the denominator the same (8).The sum is therefore 5/8 pound.

If we were to find the difference, you would subtract the smaller numerator from the larger numerator:

Assuming we're taking the second rock's weight from the first: 3/8 - 2/8.Subtract the numerators (3 - 2 = 1) while keeping the denominator the same (8).The difference is therefore 1/8 pound.

I have part A however idk how to work out part B how would i write the equation out???

Answers

Using your approximate y-intercept on the line of best fit, your equation would be y=11/7x + 3. 

We find the slope by choosing two points that are on the line:

(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well.  The formula for slope is:
m=y₂-y₁/x₂-x₁

m=7-18/2-9 = -11/-7 = 11/7

Slope intercept form, y=mx+b, has the slope and the y-intercept.  Plugging those in we have y=11/7x+3.
The generic equation of the line is:
 y-yo = m (x-xo)
 We look for the slope:
 m = (y2-y1) / (x2-x1)
 m = (18-15) / (9-7)
 m = (3) / (2)
 m = 3/2
 We write the equation choosing any point:
 y-15 = (3/2) (x-7)
 we rewrite the equation:
 y-15 = (3/2) x-10.5
 y = (3/2) x-10.5 + 15
 y = (3/2) x + 4.5
 Then, for x = 13 we have:
 y = (3/2) * (13) +4.5
 y = 24

1000 + 2000r + 1000r²

1000r² + 2000r + 1000   <---- standard form.
Final answer:

The balance of your account after 2 years is $1,060.90. You do not have enough money in your account after 3 years to buy the $1100 guitar.

Explanation:

To write a polynomial in standard form for the balance after 2 years, we substitute the given interest rate of 3% (0.03 in decimal form) into the expression $1000(1+r)^2. This gives us $1000(1+0.03)^2. Simplifying this equation, we have:

$1000(1+0.03)^2
= $1000(1.03)^2
= $1000(1.0609)
= $1,060.90

Therefore, the balance of your account after 2 years is $1,060.90.

To determine if you have enough money in your account after 3 years to buy the $1100 guitar, we can substitute the values into the expression $1000(1+r)^3. Using the same interest rate of 3% (0.03 in decimal form) and solving the equation, we have:

$1000(1+0.03)^3
= $1000(1.03)^3
= $1000(1.0927)
= $1,092.70

Since $1,092.70 is less than the cost of the guitar, you do not have enough money in your account after 3 years to buy the guitar.
