Base of a prism is a right triangle with legs 3 feet and 4 feet. The height is 13 feet , what is the volume?
julsineya [31]

Answer:

Triangular prisms

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h

In the diagram provided, line I is parallel to line m. Select which of the following statements could be used to prove that
atroni [7]
<h3>Answer: There is only one answer and it is choice B</h3><h3>Angle 1 and angle 4 are alternate interior angles</h3>

========================================================

Explanation

  • A. This is false because it should be angle 4 + angle 5 = 180 without the angle 6. Adding on angle 6 results in some angle larger than 180. Note how angle 5 = (angle 3)+(angle 6).
  • B. This is true and useful to showing that the three angles of a triangle add to 180 degrees. This is because you'll use the fact that angles 4, 5 and 6 combine to 180 degrees.
  • C. While this is a true statement by the exterior angle theorem, it is not useful to the proof. It is better to state that angle 2 and angle 6 are congruent because they are alternate interior angles.
  • D. Like choice C, it is true but not useful. It's better to say that angle 1 is congruent to angle 4. See choice B above.

Note how it's not enough for a statement to be true. It also needs to be relevant or useful to the context at hand. A more simpler example of this could be stating that x+x = 2x.

An isosceles triangle has a perimeter of 18 cm. Find a function that models its area A in terms of the length of its base b.
IgorLugansk [536]
So.... notice the picture below

now, we know what the "height" or "altitude" is
now, we also know the perimeter is 18cm

so, k + k + b = 18
or 2k + b = 18
thus  \bf k=\cfrac{18-b}{2}

so... one can say that \bf \textit{area of a triangle}=A=\cfrac{1}{2}bh\qquad &#10;\begin{cases}&#10;b=b&#10;\\\\&#10;h=\sqrt{k^2-\left( \frac{b}{2} \right)^2}&#10;\\\\&#10;h=\sqrt{k^2-\frac{b^2}{4}}\\&#10;--------------\\&#10;k=\frac{18-b}{2}\qquad thus\\&#10;--------------\\&#10;h=\sqrt{\left( \frac{18-b}{2} \right)^2-\frac{b^2}{4}}&#10;\end{cases}\\\\&#10;-----------------------------\\\\&#10;A=\cfrac{1}{2}\cdot b\cdot \sqrt{\left( \frac{18-b}{2} \right)^2-\frac{b^2}{4}}

and you can simplify it if you wish.. not sure you have to

What is the equation of the line that is parallel to y =1/5x+4
atroni [7]

Answer:

y=(1/5)x-5

Step-by-step explanation:

The given equation is

y=(1/5)x+4

This is of the form

y=mx+b

which is called the slope-intercept form because

m is the slope

b is the y intercept.

In this case,

m=1/5

b=4

you can see from the chart that this matches the red line.

If two lines are parallel, they must have the same slope. So we know that the slope of the desired line is 1/5.  So, now we know that

y=(1/5)x+b

Since the line must go through the point (5,-4), we have

-4=(1/5)(5)+b

-4=1+b

b=-5

So, the desired line is

y=(1/5)x-5
