Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise defin
ohaa [14]

Answer:

C

Step-by-step explanation:

D is missing 2 ideas.

  • An angle can be formed by a mixture of the types of figures quoted.
  • An angle has common or shared endpoint.

B: to me is unclear. A line does not have an endpoint. A ray does.

A: you need to mention that the lines are coplanar.

I think, brief though it is, C is the most complete and at the same time simplest choice.

What's the volume? <br><br><br> I honestly just need the formula.
Arturiano [62]

Answer:

v=364.5\ m^3

Step-by-step explanation:

<u>Volume Of A Regular Solid</u>

When a solid has a constant cross-section, the volume can be found by multiplying the area of the base by the height. The area of a trapezium is

\displaystyle A_t=\frac{b_1+b_2}{2}h

where b_1 and b_2 are the lengths of the parallel sides and h the distance between them.

The figure shows a solid with a trapezoid as the constant cross-section and a height x. The volume of the solid is

\displaystyle v=A_t\ x

\displaystyle v=\frac{b_1+b_2}{2}\ h\ x

The image doesn't explicitly say if the length of 4.5 is the height of the trapezium or the length of that side. We'll assume the first, so our data is:

\displaystyle b_1=7m,\ b_2=11m,\ h=4.5m,\ x=9m

We now compute the volume

\displaystyle v=\frac{7+11}{2}.(4.5)(9)=364.5

\boxed{\displaystyle v=364.5\ m^3}

The inverse of the function f(x) = x + 10 is shown.
IgorLugansk [536]

Answer:

So, the answer is 20

Step-by-step explanation:

f(x) =  \frac{1}{2} x + 10 =  =  =  >  \\ f(x) - 10 =  \frac{1}{2} x =  =  =  >  \\ 2f(x) - 20 = x =  =  =  >  \\  {f}^{ - 1} (y) = 2y - 20 =  =  =  >  {f}^{ - 1} (x) = 2x - 20
