Answer:
Part A) Is a square
Part B) Is a rectangle
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The figure show a rectangular prism with a square base
Part A) A cross section formed by a plane that intersects the prism parallel to its base would take the shape of a
we know that
A cross section is the intersection of a figure in three-dimensional space with a plane
A plane parallel to the base of a rectangular prism will intersect a cross section that is the same shape as its bases.
so
The cross section is a square
Part B) A cross section formed by a plane that intersects the prism perpendicular to its base would take the shape of a
we know that
A plane perpendicular to the base of a rectangular prism will intersect a cross section that is the same shape as its lateral faces
so
The cross section is a rectangle
Answer:
Step-by-step explanation:
We can use the quadratic formula to get the answer to this
Quadratic Formula: -b +- √b² - 4ac/2a
Once we input A, B, and C into this, and solve any multiplication, we get
x = -1 +- √1 + 20/2
We divide by 2a, which 2a = 2.
-0.5 +- 10.5.
these are the following values of x:
x = 10
x = 11
Pretty sure this is it, hope it helps!

Answer:
The equation of demand function is

Step-by-step explanation:
We have two point demand function
(38000,10) and (42000,8)
Here
=38,000,
=10,
=42000,
=8
The slope of the demand function line is




The equation of demand function is





<span>3x+5y=2 (1)
9x+11y=14 (2)
multiply equation (1) by 3
9x + 15y = 6
so
</span>9x + 15y = 6 (1')
9x + 11y =14 (2)
-------------------------subtract
4y = -8
y = -2
3x+5y =2
3x+5(-2) =2
3x - 10 = 2
3x = 12
x = 4
answer
(4, -2)
