find the measure of a line EC​

Answer:

Expert Verified

Step-by-step explanation:

the diameter is 57.2 in, then the radius is half that, or 28.6 in. The volume of a sphere is V = (4/3)πr³, and so the volume of this hemisphere is (2/3)πr³

The volume of the hemisphere given its diameter is 47,697.7 in³.

The volume of an object is the amount of space that is in the object. A hemisphere is a three-dimensional object that has the shape of a semicircle.

The volume of the hemisphere = 2/3πr³

r = 56.7 / 2 = 28.35 in

2/3 x 28.35³ x 3.14 = 47,697.7 in³

Answer:

-1 is not in domain

0 and 2 both are in domain.

Explanation:

The radical function must have the domain greater or equal to 0. Here is why.

If we substitute any negative numbers in the equation

[tex]y = \sqrt{x} [/tex]

Then we would get the Imaginary Number, meaning it doesn't exist in Real Number system. That's why any negative real numbers cannot be part of the domain.

But that's for y = square root of x. There are like 4 types of radical function but this one is for example.

The equation in the question is the same type as the example equation.

Therefore, Connor has 7 nickels and 1 penny.

Answer:

The original price was $821.25

Step-by-step explanation:

The price of an object is $878.74 including a tax of 7%.

We are required to find the original price.

If the tax is 7%, then the total price is 100+7=107% of the original price.

Thus, $878.74 is the 107% of the original price x, thus:

x = $878.74/107*100 = $821.25

The original price was $821.25

Explanation:

The domain is the set of allowed x inputs. The range is the set of possible y outputs.

The set {-2,-1,0,1,2} represents all the possible x inputs

Let's plug each of those into the equation y = 3x-6 to find the corresponding paired out puts.

Note: y = f(x), so f(x) = 3x-6 is the same as y = 3x-6.

---------------

If x = -2, then,

y = 3x-6

y = 3(-2)-6

y = -6-6

y = -12

We see that x = -2 and y = -12 pair up together.

The value -2 in the domain maps to -12 in the range.

----------------

If x = -1, then,

y = 3x-6

y = 3(-1)-6

y = -3-6

y = -9

The input x = -1 in the domain maps to the output y = -9 in the range

So far the range consists of {-12, -9} in either order.

The answer is between A and D

-----------------

If x = 0, then,

y = 3x-6

y = 3(0)-6

y = 0-6

y = -6

So -6 is also part of the range. We have {-12, -9, -6} so far. The answer is still between A and D.

------------------

If x = 1, then,

y = 3x-6

y = 3(1)-6

y = 3-6

y = -3

The range updates to {-12, -9, -6, -3}

A and D are still equally valid

-------------------

We have one more x value to try

If x = 2, then,

y = 3x-6

y = 3(2)-6

y = 6-6

y = 0

Since y = 0 is in the range, instead of y = 1, this rules out choice A

The answer is therefore D.  {-12, -9, -6, -3, 0}

Answer and Step-by-step explanation:

3x + 7 + 10x = 7 + 13x + 10

13x + 7 = 13x + 17

0 = 10

No solutions

-6x -6 + 8x = -5 + 2x -1

2x - 6 = -6 + 2x

0 = 0

Many solutions.

The first equation has no solutions.

The second equation has infinitely many solutions.

Answers:

1. No solutions

2. Infinitely many solutions

Step-by-step explanation:

[tex]3x+7+10x=7+13x+10[/tex]

Add common terms from both sides of the equation (10x and 3x) & (7 and 10)

[tex]13x+7=17+13x[/tex]

Subtract common terms from both sides (13x and 13x)

[tex]7\neq 17[/tex]

7 does not equal 17; thus, there are no solutions

[tex]-6x-6+8x=-5+2x-1[/tex]

Add common terms from both sides of the equation (-6x and 8x) & (-5 and -1)

[tex]2x-6=-6+2x[/tex]

Reorder the right side of the equation

[tex]2x-6=2x-6[/tex]

Since this is a true statement, there are infinitely many solutions

What is my perfect crime? I break into Tiffany's at midnight. Do I go for the vault? No, I go for the chandelier. It's priceless. As I'm taking it down, a woman catches me. She tells me to stop. It's her father's business. She's Tiffany. I say no. We make love all night. In the morning, the cops come and I escape in one of their uniforms. I tell her to meet me in Mexico, but I go to Canada. I don't trust her. Besides, I like the cold. Thirty years later, I get a postcard. I have a son and he's the chief of police. This is where the story gets interesting. I tell Tiffany to meet me in Paris by the Trocadero. She's been waiting for me all these years. She's never taken another lover. I don't care. I don't show up. I go to Berlin. That's where I stashed the chandelier.

Answer:

0.2

Step-by-step explanation:

Given the regression model :

y = 1.6x - 4.1

At x = 3

Predicted value = 1.6(3) - 4.1 = 0.7

If actual value at x = 3 is 0.9

The residual value at x = 3 ;

Residual value is the difference between the actual and predicted value :

Actual at x = 3 minus predicted at x = 3

Hence, Residual = 0.9 - 0.7 = 0.2

Residual is the difference between the predicted value and the actual value of the response variable

The residual at x = 3 is 0.2

The linear regression is given as:

[tex]y = 1.6x - 4.1[/tex]

The predicted value at x = 3 is calculated by substituting 3 for x in the linear regression

So, we have:

[tex]y = 1.6 \times 3 - 4.1[/tex]

[tex]y = 4.8 - 4.1[/tex]

[tex]y = 0.7[/tex]

The actual value is given as 0.9.

So, the residual is calculated using:

[tex]Residual =Actual - Predicted[/tex]

This gives

[tex]Residual =0.9 - 0.7[/tex]

[tex]Residual =0.2[/tex]

Hence, the residual at x = 3 is 0.2

Answer:

y = 2x - 259/115 [slope-intercept]

-230x + 115y = -259 [standard form]

Step-by-step explanation:

First make sure both of the intersecting lines are in standard form: Ax + By = C.

Then, multiply one of the equations by a certain quantity so one of the variables can be canceled out.

For example:

given 5x + y = 7, and 3y = 4x - 5.

You can rearrange the second equation since it is not currently in standard form.

So all we need to do is subtract both sides by 4x since that will leave the constant of C by itself.

3y = 4x - 5 → 3y - 4x = 4x - 5 - 4x →

3y - 4x = -5.

Now adding a negative number is the same as subtracting a positive number, this is because subtraction is the opposite of adding.

So 3y - 4x = -5 = 3y + (-4x) = -5 →

-4x + 3y = -5

Answer:

$12.40

subtract 12.80 from 50 to get 37.20 then divide by 3

If you look at the question, You would see a pattern. That pattern is the amount of slices in one week is divided by 2 the next week. So on the fourth week you would do 320/2 and get 160. if you keep carrying on the pattern yourself, you would do: 160/2 = 80. 80/2 = 40. And there's your answer. week 4 we had 160 slices sold. week 5 80 slices sold. Week 6 40 slices sold
