The piecewise function that best models her weekly pay h(t) is given by:

A piecewise-defined function is a function that has different definitions, depending on the input of the function.

For this problem, we have that:

Her weekly pay is calculated differently according to the number of hours worked, divided into two cases as follows:

For up to 40 hours, she receives the standard wage of $12, hence:

h(t) = 12t, 0 ≤  t ≤ 40.

For more than 40 hours, she receives $12 x 40 = $480 plus 1.5 x $12 = $18 per hour worked, hence:

h(t) = 480 + 18t.

Hence the piecewise function that best models her weekly pay h(t) is given by the following definition, from the equations that we found prior in this problem:

Answer:9

Step-by-step explanation:

Mass of the pipe= 100.8kgs

Mass is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force.

mass= density x volume

given that, the area of cross- section of the pipe is rectangular ring with area,

A=(10x10) - (15x8)

   =180-120

   =60 cm²=0.006 m²

length of the pipe = 150 cm=h

volume= A. h

            = 0.006x150x10⁻²

            = 0.720x10⁻²

             = 0.0072 m³

Density =14000kg/m³

     mass= density x volume

               = 14000 x 0.0072

                = 14 x 7.2

                = 100.8 kg

we got that the mass of the pipe in kgs is = 100.8kgs

Answer:

The pipe weighs 100.8 kg.

Step-by-step explanation:

Mass is essentially a body of matter's resistance to having its speed or position change when a force is applied. The change caused by an applied force is smaller the more mass a body has.

density x volume equals mass.

Considering that the pipe's cross-section is a rectangular ring of area,

A=(10x10) - (15x8)

  =180-120

  =60 cm²=0.006 m²

length of the pipe = 150 cm=h

volume= A. h

           = 0.006x150x10⁻²

           = 0.720x10⁻²

            = 0.0072 m³

Density =14000kg/m³

    mass= density x volume

              = 14000 x 0.0072

               = 14 x 7.2

               = 100.8 kg

we got that the mass of the pipe in kgs is = 100.8kgs

Answer: Large number: 36

Smaller number: 9

Step-by-step explanation:

The statement given is true.

If the sum of tine acute angles of a triangle is greater than 90 , then the triangle is acute.

The acute angle can be defined as the angle  less than 90°. Or we can say that the angle which is between 0° and 90° is called as an acute angle of a triangle. In the triangle all the angles gives the sum of 180 degree, that means, at least two angles in every triangle are always acute angles.

According to statement given in the question. This statement is absolutely true. If the sum of two acute angle is greater than 90 then the third angle of that polygon i.e. triangle must be less than 90 which makes the whole triangle a acute . Since, all the angles are now acute angles that means less than 90 thus this made the triangle as a acute triangle.

Answer:

A′(2, −2), B′(−3, 3), C′(5, 2)  (2nd choice)

Step-by-step explanation:

Rotating a point 270° clockwise about the origin is the same as rotating the point counterclockwise by 90°

In either case, the coordinates of any point (x, y) become new coordinates (-y, x)

I will summarize the original and rotated points,.

Original          Rotated

B( 3,  3)           B'(-3,  3)            no luck, both 2nd and 4th choices have this
C(2, -5)           C'( 5, -2)            only the 2nd choice fits all three

Answer: A′(2, −2), B′(−3, 3), C′(5, 2)

The coordinates of triangle A′B′C′ after rotating triangle ABC 270° clockwise are A′(2, −2), B′(−3, 3), and C′(5, 2).

The correct answer is (A).

The coordinates in a graph indicate the location of a point concerning the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

To rotate a point (x,y) 270° clockwise about the origin,

We can use the formulas:

x' = y and y' = -x.

So, to rotate triangle ABC 270° clockwise, we need to apply these formulas to each vertex:

A' = (-2, 2) rotated 270° = (2, -2)

B' = (3, 3) rotated 270° = (-3, 3)

C' = (2, -5) rotated 270° = (5, 2)

Step-by-step explanation:

Start with the median. That's the middle number of an ordered set of numbers.

a 8 b               is what you have so far.

Now the range between a and b is 4 which means that a and b differ by 4.

a + 4 =  b

The mean will solve this quickly. Put a + 4 for b

[(a + 8  + a + 4)]/3 = 8            Combine like terms

(2a + 12)/3 = 8                       Multiply both sides by 3

3 (2a + 12)/3 = 8 *3              

2a+12 = 24                            Subtract 12 from both sides

2a + 12 - 12 = 24-12               Combine

2a = 12

a = 6

but we know that the range between a (which is 6 ) and b is a + 4 = 10

So b must equal 10

Answer:

z = - 1 , z = 5

Step-by-step explanation:

| 3z - 6 | = 9

the absolute value function always gives a positive result, however, the expression inside can be positive or negative, that is

3z - 6 = 9 ( add 6 to both sides )

3z = 15 ( divide both sides by 3 )

z = 5

or

- (3z - 6) = 9

- 3z + 6 = 9 ( subtract 6 from both sides )

- 3z = 3 ( divide both sides by - 3 )

z = - 1

As a check

substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

x = 5

| 3(5) - 6 | = | 15 - 6 | = | 9 | = 9 = right side

x = - 1

| 3(- 1) - 6 | = | - 3 - 6 | = | - 9 | = 9 = right side

then solutions are z = - 1 , z = 5

The solution of the given linear equation in one variable (m-2)-5=8-2(m-4) is at m = 23/3.

According to the given question.

We have a linear equation in one variable

(m-2)-5=8-2(m-4)

As we know that, the linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

Thereofre, the solution of the linear equation in one variable (m-2)-5=8-2(m-4) is given by

(m -2) -5 = 8 -2(m -4)

⇒ m -2 - 5 = 8 -2m + 8     (by distributive rule)

⇒ m -7 = 16 - 2m                   (adding and subtracting the line terms)

⇒ m + 2m = 16 + 7

⇒ 3m = 23

⇒ m = 23/3

Hence, the solution of the given linear equation in one variable (m-2)-5=8-2(m-4) is at m = 23/3.

Discount percentage = [(Discount)/(Marked price)]× 100

         15 = Discount / 1200 × 100

         15  = Discount / 12

       Discount = 15 × 12

The summation notation for given arithmetic series is ∑21-2n , where n starts from 0.

The given series is 21+19+17+ . . .

On looking at the series we can easily notice that there is an decrease of 2 from one term to the next successive term.

So the formula will be (-2n +/- something).

Our first term is 21 and then decrease of 2, So we can say that the formula will be (21 - 2n) and n starts from 0.

So if n=0, our first term is 21

If n=1, our second term is 19

If n=2, our third term is 17

and so on.

So, we have the expression (21 - 2n).
