A carpenter charges $30 per hour for up to eight hours each day and increases this rate by 50% for additional hours. The carpent

er will not work more than ten hours per day. If this daily cost function is modeled by y = f(x) and graphed, which statement is not correct?
A) f(0) = 0, f(8) = 240, and f(10) = 330.
B) The domain is [0, 10] and the range is [0, 330].
C) The graph is increasing on the interval (8, 10) with a slope of 45.
D) If a $20 trip charge is added, the new x-intercept will be (20, 0).

Answer:

D. If 20$ a trip charge is added, the new x-intercept will be (20,0)

This statement is false. The original graph started at (0,0), the x-intercept. Adding a 20$ trip charge moves the graph up 20 so there would not be an x-intercept.

Which of the following figures could represent the cross section of a rectangular pyramid? Select all that apply.
Rama09 [41]

Answer:

Options C and E

Step-by-step explanation:

Option A. Circle

We can't get a cross section in the form of a circle.

Option B. Cube

We can't get a cross section in the form of a cube.

Option C. Rectangle

When we slice a rectangular pyramid parallel to the base but not through the vertex, we get a Rectangle.

Option D. Square

We can not get a square by slicing a rectangular pyramid.

Option E. Triangle

By slicing a rectangular pyramid perpendicular to the base and passing through the vertex we can get the cross section in the form of  triangle.

Options C and E will be the answer.

usa el teorema de la altura para proponer como se podria construir un segmento cuya longitud sea media proporcional entre dos se
Mrac [35]
Usando el teorema de altura 

El teorema de altura relaciona la altura (h) de un triángulo rectángulo (ver figura) y los catetos de dos triángulos que son semejantes al anterior ABC, al trazar la altura (h) sobre la hipotenusa. De manera que e<span>n todo </span>triángulo rectángulo, la altura (h<span>) relativa a la </span>hipotenusa<span> es la </span>media geométrica<span> de las dos proyecciones de los </span>catetos<span> sobre la </span>hipotenusa<span> (</span>n<span> y </span>m<span>). Es decir, se cumple que:

</span>\frac{n}{h}= \frac{h}{m}

Dado que el problema establece <span>construir un segmento cuya longitud sea media proporcional entre dos segmentos de 4 y 9 cm, entonces, digamos que n = 4cm y m = 9cm tenmos que:

</span>\frac{4}{h}= \frac{h}{9}

De donde:

h= \sqrt{(4)(9)}=\sqrt{36}=6cm

¿Cómo se podria construir si los segmentos son de a cm y b cm?

Si los segmentos son de a y b cm entonces a y b son parámetros que pueden tomar cualquier valor positivo siempre que se cumpla que:

h= \sqrt{ab}

A line goes through the points (4, 5) and (2,-6). Write the equation of the line in slope-intercept
kompoz [17]

Answer: 11/2x - 17

Step-by-step explanation:

First find the slope.

I learned this doing the y2-y1 method.

Do -6 - 5 which equals -11

And 2 - 4 = -2

This makes -11/-2 = 11/2

Then if you you were to graph,, find two points which should give you -17.
