After the last step, you have to plug x into the equations. 5(5)+8=33 and 8(5)-1=39. You do this because it asks you to find the measurements of the angles, meaning the whole thing, not just x. To check, you add the two values of EFG and EFH, and they should equal EFG. 33+39=72, so it all checks out!
Answer:
The exact cost of producing the 21st food processor is $38.52.
The marginal cost to approximate the cost of producing the 21st food processor is $38.24
Step-by-step explanation:
Consider the provided function.

(A) Find the exact cost of producing the 21st food processor
The exact cost producing 21st food processor is C(21)-C(20)
Substitute x=21 in above function.



Substitute x=20 in above function.



The exact cost producing is:

Hence, the exact cost of producing the 21st food processor is $38.52.
Part (B) Use the marginal cost to approximate the cost of producing the 21st food processor,
To find the marginal cost first differentiate the function with respect to x.


Now substitute x=21 in above function.


The marginal cost to approximate the cost of producing the 21st food processor is $38.24
Answer:
$3.00
Step-by-step explanation:
Step 1. Calculate the <em>pounds of broccoli</em>.
Start with what you know: you want 32 oz of broccoli.
You know that 1 lb = 16 oz. Calculate the weight in pounds
Wt = 32 × 1/16
Wt = 2 lb
===============
Step 2. Calculate the <em>cost of the broccoli</em>.
$1.50 = 1 lb Calculate the cost
Cost = 2 × 1.50/1
Cost = $3.00
