Answer:
Step-by-step explanation:
For this case we have the following value:
We can convert this first to 
like this:
Now we use the fact the the pressure is defined as 
, whre P is the pressure, F the force and A the area, so then 
and then we can replace this:
Now from definition of work we know that 
where W is the work, F the force and d the distance, so then is equivalent 
And if we replace this into the equation we got:
4 = 7 - 3
1 = 4 - 3
-2 = 1 - 3
-5 = -2 - 3
=> An = A (n-1) - 3, where A1 = 7
The next term is A6 = A5 - 3 = - 5 - 3 = - 8
So the answer is the fourth option.
Answer:
Options A, D and E.
Step-by-step explanation:
Formula to calculate the volume of the triangular prism is,
Volume of the triangular prism = (Area of the triangular base)×(height)
= B × h
Area of the right triangular base = 
= 
= 56 m²
Volume of the prism = 
= 392 cubic meter
Therefore, from the given options correct options are Option A, Option D and Option E.
You can describe the domain by every possible x value in the function, since that function has a vertical intersection line which means the x value will never pass it on the negative side, the domain would be from -2 to all the postive numbers, X > -2 or (-2,∞).
For the range, simply it's all the possible y values. In that function it's impossible to go under 0 or negative value. That means the range would be Y>0 or (0,∞).
If you want to know if it's a function or not you could try the vertical line test, select any x value and draw straight line on it, if the line crosses 2 y points in the same x value it wont be a function, In your case each x value has it's own Y value.
So the answer is Domain x>-2; Range y>0; Yes, it is a function
