Answer:</h2>
The marginal cost when x=8 is:
375
<h2>
Step-by-step explanation:</h2>
We know that the marginal function for a cost function C(x) at x=a
is given by:
C'(x) at x=a
Here we have the cost function C(x) as:

Now we find the derivative of C(x) with respect to x.
i.e.

( Since,
)

Hence, we get:

Answer:
Length of the door, <em> l</em> = 5 inches (<em>in</em>)
Width or Breadth of the door, <em>w</em> = 2 inches (<em>in</em>)
Perimeter p = 2(l + w)
= 2( 5 + 2) <em>inches</em>
<em> = 2(5) inches + 2(4) inches</em>
= 10 <em>inches</em> + 4 <em>inches</em>
= 14 <em>inches</em> or 14 <em>in</em>
Step-by-step explanation:
The perimeter of a plane shape is the measurement of the length of its outside boundary, which means the distance around its edges.
The door in the sketch is the shape of a rectangle. the distance around the edge of the door is the sum of all the sides. The longer side of a rectangle is called the length and it is usually represented by letter<em> l</em> while the shorter side is known as width or breadth represented by letter <em>w</em> and<em> b </em>respectively. The perimeter is calculated by the formula 2(l + w). where l means the length and w represents the width.
Answer:
16 nickels thicker
Step-by-step explanation:
You would need 20 nickels for 1 dollar and only 4 quarters for 1 dollar. Do 20 minus 4 and your answer is 16 nickels. The stack of nickels is 16 coins thicker. Hope this helped!
Simplifying
y = -25x + 200
Reorder the terms:
y = 200 + -25x
Solving
y = 200 + -25x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 200 + -25x
1/9 is the answer for that question
