something costs $10.39 and i get 02.59lbs what would it cost

Step-by-step explanation:

Step 1:  List out all of the formulas for the trigonometric functions

sin(x) = opposite/hypotenuse

cos(x) = adjacent/hypotenuse

tan(x) = opposite/adjacent

Step 2:  Find the values for the given numbers

sin(J) = opposite/hypotenuse = 24/25

tan(J) = opposite/adjacent = 24/7

sin(K) = opposite/hypotenuse = 7/25

tan(K) = opposite/adjacent = 7/24

Step 3:  Check if the answers match

24/25 = 24/25 So it is TRUE

24/7 != 7/25 So it is FALSE

7/25 != 24/25 So it is FALSE

7/24 = 7/24 So it is TRUE

Answer: TRUE, FALSE, FALSE, TRUE

Answer:

These two angles (140° and 40°) are Supplementary Angles, because they add up to 180°:

Notice that together they make a straight angle.

supplementary angles 60 and 120

But the angles don't have to be together.

These two are supplementary because

60° + 120° = 180°

Step-by-step explanation:

(Is it weird that I had the same exact question? Maybe not. But I also found another person with the same question as me. It was a different question though. This is probably too late. But I'm just gonna try to answer it for anyone who needs it.

"Linear regression" is just a fancy word for scatter plots. Scatter plots take place in graphs. The dots or plots are scattered and the way they are scattered means something. If it's going down, it's negative, up it's positive, and if it's scattered, it has no corrolation.

Also, you should have learned this in 9th grade. So, check your notes.

If you don't have it, WRITE IT!!!

To find it in your calculator:

1. Go to "Lists and Spreadsheets"

2. Rename the first column "x" and the second on "y"

3. Write all of your numbers in the right column

1, 5, 3, 7 under the "x"

8.67, 10.50, 9.58, 11.41 under the "y"

4. Move your cursor to an empty cell

4. Click: "MENU" #4 #1 #3

5. Rename the correct rows "x" and "y" and press enter

6. Now you can find "m" and "b"

7. Then move your cursor to an empty cell and click "doc" "insert" #7

8. Find the x-axis and find "x"

9. Find the y-axis and find "y"

10. Now press "MENU" #4 #6 #1

And you found your y=mx+b: y=0.5x+8.2

Now, how much money per hour.

So you've found your m and b but now you have to:

1. Replace y with 15 and solve it

15=0.5x+8.2

-8.2       -8.2

6.8=0.5x

Divide 0.5 on both sides

6.8/0.5=13.6

13.6=x

Missing Part of the question:

a) Assume you wish to determine the maximum and minimum temperatures you would experience. the domain to study for the function H(x) would be?

b)The is one critical number for the function on the domain in part a and it is?

c) The maximum temperature you would experience is ?

d) The minimum temperature you would experience is ?

Answer:

a. Domain : [tex]4 \leq x \leq 41[/tex]

b. Critical point: [tex]x = 12.33[/tex]

c. The maximum is 115.09

d. The minimum is 100.62

Step-by-step explanation:

Given

[tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

Solving (a): The domain of H(x)

From the question, we understand that the distance between the two stores is 45ft

Let the first stove be at point A (0 ft) and

the second stove be at point B (45ft)

Since you move back and forth within 4ft from either stoves, then

Your maximum distance at A is (0 + 4) ft = 4ft

Your minimum distance at B is (45 - 4) ft = 41ft

Hence, the domain is: [tex]4 \leq x \leq 41[/tex]

Solving (b): Critical Value

First, we have to differentiate H(x) w.r.t x

[tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

Differentiate

[tex]H'(x) = 0 -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]

[tex]H'(x) = -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]

Equate H'(x) to 0

[tex]0 = -\frac{120}{x^3} + \frac{480}{(45- x)^3}[/tex]

Rewrite as:

[tex]\frac{120}{x^3} = \frac{480}{(45- x)^3}[/tex]

Cross Multiply

[tex]480 * x^3 = 120 * (45 -x)^3[/tex]

[tex]480 * x^3 = 120 * (45 -x)*(45 -x) * (45 -x)[/tex]

[tex]480 * x^3 = 120 * (2025 -90x +x^2) * (45 -x)[/tex]

[tex]480 * x^3 = 120 * (91125 -4050x +45x^2 -2025x - 90x^2 - x^3)[/tex]

[tex]480 * x^3 = 120 * (91125 -4050x -2025x+45x^2 - 90x^2 - x^3)[/tex]

[tex]480 * x^3 = 120 * (91125 -6075x-45x^2 - x^3)[/tex]

Divide both sides by 120

[tex]4x^3 =91125 -6075x-45x^2 - x^3[/tex]

[tex]4x^3 +x^3-91125 +6075x+45x^2= 0[/tex]

[tex]5x^3-91125 +6075x+45x^2= 0[/tex]

[tex]5x^3+45x^2 +6075x-91125= 0[/tex]

Divide through by 5

[tex]x^3+9x^2 +1215x-18225= 0[/tex]

Solving for x, we have that

[tex]x\approx \:12.33067[/tex]

[tex]x = 12.33[/tex]

Hence, the critical point is 12.33

Solving (x): Maximum temperature

Here, we simply substitute the endpoints of the domain in [tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

Let x = 4

[tex]H(4) = 100 + \frac{60}{4^2} + \frac{240}{(45 - 4)^2}[/tex]

[tex]H(4) = 100 + \frac{60}{16} + \frac{240}{(41)^2}[/tex]

[tex]H(4) = 100 + \frac{60}{16} + \frac{240}{1681}[/tex]

[tex]H(4) = 100 + 3.75+ 0.14277215942[/tex]

[tex]H(4) = 103.892772159[/tex]

[tex]H(4) = 103.89[/tex] --- approximated

Let x = 41

[tex]H(41) = 100 + \frac{60}{41^2} + \frac{240}{(45 - 41)^2}[/tex]

[tex]H(41) = 100 + \frac{60}{41^2} + \frac{240}{4^2}[/tex]

[tex]H(41) = 100 + \frac{60}{1681} + \frac{240}{16}[/tex]

[tex]H(41) = 100 + 0.03569303985 + 15[/tex]

[tex]H(41) = 115.03569304[/tex]

[tex]H(41) = 115.04[/tex] ---- approximated

Compare both values: The maximum is 115.09

Solving (d): The minimum temperature

In (b), we have that:

[tex]x = 12.33[/tex] --- critical point

The minimum occurs at this point

Substitute 12.33 for x in [tex]H(x) = 100 + \frac{60}{x^2} + \frac{240}{(45 - x)^2}[/tex]

[tex]H(12.33) = 100 + \frac{60}{12.33^2} + \frac{240}{(45 - 12.33)^2}[/tex]

[tex]H(12.33) = 100 + \frac{60}{12.33^2} + \frac{240}{32.67^2}[/tex]

[tex]H(12.33) = 100 + \frac{60}{152.0289} + \frac{240}{1067.3289}[/tex]

[tex]H(12.33) = 100 + 0.39466180443 + 0.22486039682[/tex]

[tex]H(12.33) = 100.619522201[/tex]

[tex]H(12.33) = 100.62[/tex] --- approximated

Hence, the minimum is 100.62

Please find the complete question in the attached file.

In this question first, we include the quantity of food that these cats eat daily.  

[tex]\to \frac{3}{4}= 0.75\\\\\to \frac{1}{2}= 0.5 \\\\ \to 0.75+ 0.5=1.25[/tex]

They are now able to eat the total of meat we consume on a daily basis, that the food we still eat is 1,25 cans each day, and we must have the full 3 cans.  

[tex]\to 1.25 \times 2=2.50[/tex]

2.5 cans and they eat 2.5 cans every 2 years with every other day so we'll have to purchase more meat. So let's go to buy some at our favourite place. 2.5 cans one another day to allow us to give the Bobo leftover .5 a can and open the new Rover can.  

We also left this meal 1.25 cans, so that we can give it to them tomorrow. The feed time would not allow them to purchase food as we have the right quantity of food left. But we went for 6 cans in 4 days. Let's figure out how we're going to divide 60 by 4  =15

So we have 15 times 6 now, because that will provide us with the answer   [tex]\to 15 \times 6=90[/tex]

We finally find out just how much we pay by 90 cans in 60 days so we will find out what it costs us.  

That's the number of cans we get from each purchase and we will divide 90 by 3.  

[tex]\to \frac{90}{3}=30[/tex]

They are going to multiply 30 times 5 now, since that is the sum of money to buy.

[tex]\to 30 \times 5=150[/tex]

Answer:

A = 3

2A5A0A2 = 2353032

Step-by-step explanation:

Given:

2A5A0A2 is divisible by 9

2A5A0A2 can be divisible by 99 if the sum of the digits can be divided by 9

Digits A is between 0 to 9

2 + A + 5 + A + 0 + A + 2 = 9x

Where,

x = multiples of 9

9 + 3A = 9x

Make A the subject

A = (9x - 9) / 3

When x = 0

A = {9(0) - 9} / 3

= (0 - 9) /3

= -9/3

= -3

When x = 1

A = (9x - 9) / 3

= 9(1) - 9 /3

= 9-9/3

=0/3

A = 0

When x = 2

A = (9x - 9) / 3

= 9(2) -9 / 3

= 18-9/3

= 9/3

A = 3

When x = 3

A = (9x - 9) / 3

= 9(3) - 9 / 3

=27 - 9 /3

= 18/3

A = 6

When x = 4

A = (9x - 9) / 3

= 9(4) -9 /3

= 36-9/3

= 27/3

= 9

Recall, Digits A is between 0 to 9

Substituting A = 0

2050002 ÷ 99

= 20707.09

Substituting A = 3

2A5A0A2

2353032 ÷ 99

= 23,768

Substituting A = 6

2A5A0A2

2656062 ÷ 99

= 26,838.91

Substituting A = 9

2A5A0A2

2959092 ÷ 99

= 29,889.82

Therefore, the only A digit that will not give a decimal number when divided by 9 is 3

A = 3

Step-by-step explanation:

The length of AB is 10 units.

A line segment is a subset of a line which has two end points.Distance of a given line segment with two endpoints and a pair of co-ordinates can be obtained by [tex]\sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex] this formula know as distance formula.

According to the given question co-ordinate of two points are given and we have to find the distance.

We know that distance between two points is given by  

[tex]\sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]

Here A = (x₁,y₁) = (-2,10) and B = (x₂,y₂) = (4,-2).

∴ AB = [tex]\sqrt {\left( {-2 - 4 } \right)^2 + \left( {10 -2 } \right)^2 }[/tex].

AB = [tex]\sqrt {\left( {-6} \right)^2 + \left( {8 } \right)^2 }[/tex]

AB = [tex]\sqrt {\left( {36} \right) + \left( {64} \right) }[/tex]

AB = [tex]\sqrt {100}[/tex]
