A function is created to represent the cost per person to attend the school dance. What restrictions would
be made to the domain? (1 point)
The domain would only include integers.
The domain would only include positive integers.
The domain would only include positive numbers,
The domain would include all real numbers.

Answer:

5/3

Step-by-step explanation:

Looking at the two points, we count the rise (rise/run). It'd be 5 going up from the bottom point all the way to the same level as the top point. Then we count how many units over, which is 3. The slope of this would be 5/3. in slope form would be y=5/3x

Answer:

The slope is 6

Step-by-step explanation:

To find the slope you use the formula rise/run

The rise is the second y coordinate minus the first y coordinate

The run is the second x coordinate minus the first y coordinate

Step one:

Take any 2 points: I used (-1,2) and (-4,-3)

Step two:

Use the formula: rise/run

-4-2/-2-(-1)

-6/-1

Answer:

0.02

Step-by-step explanation:

Given a normal distribution :

Mean income (m) = 25000

Standard deviation of income (s) = 6000

X ≥ 12000

Using the relation to fund the standardized score :

Zscore =(x - m) / s

Zscore = ( 12000 - 25000) / 6000

Zscore = -13000 / 6000

Zscore = - 2.167

Using a z probability calculator :

P(Z ≤ - 2.167) = 0.015117

= 0.02

Answer:

y=-2x+15

Step-by-step explanation

A perpendicular line always has the opposite reciprocal slope of the line it is 90 degrees from.

Since the slope of the other line is 1/2, the slope of this line must be -2. And with the slope of a line -2 with point (4,7), you can start plugging in numbers.

y=-2x+b

7= -2(4)+b

7= -8+b

15=b

Therefore, the equation of the line is y=-2x+15

Answer:

[tex]180.4~cm^2[/tex]

Step-by-step explanation:

Surface Area

The surface area of a cylinder of height h and radius r is given by:

[tex]A=2\pi rh[/tex]

It only covers the lateral side of the cylinder. If both the top and the bottom sides are to be included, then:

[tex]A=2\pi rh+2\pi r^2[/tex]

The label will cover only the lateral side of the soup can that has a height of h=8.5 cm and a diameter of 6.5 cm. We need to calculate the radius which is half of the diameter r=6.5 cm / 2 = 3.25 cm.

Now we calculate the side area of the can:

[tex]A=2\pi (3.25)(8.5)[/tex]

[tex]A=173.6~cm^2[/tex]

We need to add the 0.8 cm overlap to the total area already calculated. This overlap has 0.8 cm of width and 8.5 cm of height, so this overlap area is:

[tex]A_o= 0.8*8.5=6.8~cm^2[/tex]

The total area of the label is:

[tex]A=173.6~cm^2+6.8~cm^2=180.4~cm^2[/tex]

The area of the label is [tex]\mathbf{180.4~cm^2}[/tex]

      Statements                                       Reasons

1). UW bisects ∠VUX                1). Given

2). UW bisects ∠VWX              2). Given

3). ∠VUW = ∠WUX                   3). Definition of angle bisector

4). ∠UWV = ∠UWX                   4). Definition of angle bisector

5). UW = UW                             5). Reflexive property of congruence

6). ΔUWX ≅ ΔUWV                  6). ASA postulate of congruence

Answer:

Statement is incorrect

Step-by-step explanation:

Every positive integer cannot be expressed as the sum of three or fewer perfect squares.

Supposing the number 7 only squares less than are 0, 1  and   4

Clearly 7 can not be written using three or fewer of these numbers

It is proved

By taking Cube root of 7

[tex]\sqrt[3]{7}[/tex] = 1.912931183

Now By taking  

[tex]\sqrt{7}[/tex] = 2.64575131

So both values 1.912931183 and 2.64575131 are not positive integers.

Hence the statement is incorrect.

Answer:

A)

534 rounds to 500

395 rounds to 400

B) 100

Step-by-step explanation:

A)

534 rounds to 500 because the next digit 3 is less than 5 which means that you round down.

395 rounds to 400 because the next digit 9 is greater than 5 which means that you round up.

B)

500-400=100

Answer:

Solving [tex](4g^2-9) \div (2g-3)[/tex] we get 2g+3

Option B is correct.

Step-by-step explanation:

We need to solve [tex](4g^2-9) \div (2g-3)[/tex]

We know that [tex]a^2-b^2=(a-b)(a+b)[/tex]

So, [tex]4g^2-9[/tex] can be written as [tex](2g)^2-(3)^2[/tex]

So, using above formula we will get:

[tex]4g^2-9\\=(2g^2)-(3)^2 \\Using \ formula a^2-b^2 = (a-b)(a+b)\\=(2g-3)(2g+3)[/tex]

So, numerator will become

[tex]\frac{(2g-3)(2g+3)}{(2g-3)} \\Simplifying:\\=2g+3[/tex]

So, solving [tex](4g^2-9) \div (2g-3)[/tex] we get 2g+3

Option B is correct.

That’s the real answer

The required table will be:

X      Y

-6     32

-3      17

0       2

3      -13

Since we are not given the x - values, let the x values be -6, -3, 0 and 3

Given the function of y with respect to x;

y = -5x + 2

We need to get all the y-values for the given values of x as shown;

If x  = -6

y = -5 (-6) + 2

y = 30 + 2

y = 32

If x  = -3

y = -5 (-3) + 2

y = 15 + 2

y = 17

If x  = 0

y = -5 (0) + 2

y = 0 + 2

y = 2

If x  = 3

y = -5 (3) + 2

y = -15 + 2

y = -13

Hence the required table will be:

X      Y

-6     32

-3      17

0       2

3      -13

∠A ≅ ∠Z

you can determine this by seeing that both angles have two curved lines, therefor showing they have the same measurement.

∠B ≅ ∠Y

you can also determine this by seeing that they both have one curved line showing that they share the same measurement.

∠C ≅ ∠X

once again, you can determine this by seeing that both angles are marked with three curved lines, meaning they share the same measurements.

line AB ≅ line ZY

just like before, you can determine that they are equivalent to each other by seeing that both lines have three dashes showing that they have the same measurement.

line AC ≅ line ZX

you can determine these lines are equivalent because they both have one dash showing they are the same length as each other.

line BC ≅ line YX

once again, both lines have two dashes, showing that they are equivalent in length.

ΔCAB ≅ XZY

you can determine this by seeing that all three angles and all three sides on both triangles share measurements with the other triangle
