Help find the volume please
finlep [7]

Volume of a Triangular Prism = base area x height

Area of a Triangle = 1/2 x length x width

First, we'll find the area of the base triangle. This is quite easy to do because we are given the length and width.

Length = 8

Width = 6

A = 1/2 x 8 x 6

A = 1/2 x 48

A = 24

Next, we'll plug the base area and the height into our formula.

Base area = 24

Height = 8

V = 24 x 8

V = 192

Answer: 192 m^3

Hope this helps!

How do i solve 2x^2+5x+2=9
earnstyle [38]
2x² + 5x + 2 = 9
2x² + 5x + 2 - 9 = 9 - 9
2x² + 5x - 7 = 0
x = <u>-5 +/- √(5² - 4(2)(-7))</u>
                    2(2)
x = <u>-5 +/- √(25 + 56)</u>
                   4
x = <u>-5 +/- √(81)
</u>               4<u>
</u>x = <u>-5 +/- 9
</u>            4
x = <u>-5 + 9</u>      x = <u>-5 - 9</u>
           4                   4
x = <u>4</u>              x = <u>-14</u>
      4                      4
x = 1              x = -3.5

The graph below displays the wrist circumferences and heights of six students in Alyssa’s classroom.
coldgirl [10]

Answer:

Option D(No because the wrist circumference of 16 cm is paired with two heights.


Step-by-step explanation:

In the given graph we have  set of points representing the wrist circumferences and heights of six students in Alyssa’s classroom.

x axis  represents the wrist circumference while  y axis represent the height.

Any relation is called a function if for one value of x we have only one value of y. If the graph passes the vertical line test that is if a vertical line drawn touches the graph at only one point then the graph is called a function.In the given graph for x value x=16 there are two y values 162 and 165.So the graph is not a function.

Among all the options Option D(No because the wrist circumference of 16 cm is paired with two heights.) is the right answer.

John says that 0.5y for y=1.4 is 0.7<br> Is he correct? Explain.<br> 17 points
Alona [7]
John is correct because 0.5 is equal to one half and multiplying something by its half is just same as dividing something in two and half of 1.4 is 0.5
