How many B titles
How many C titles
Answer:
Step-by-step explanation:
Given the function C(x) = x 2 + 78 x + 29 models the cost, in hundreds of dollars, to produce x thousand pens, we are to interpret C(0), C(2) and C(4).
For C(0), we are to substitute x = 0 into the given function;
C(0) = 0²+78(0)+29
C(0) = 0+0+29
C(0) = 29
Since the cost C(x) is in hundreds of dollars, C(0) = 2900
C(0) means that the cost of producing 0 thousand pen is $2,900
For C(2), we are to substitute x = 2 into the given function;
C(2) = 2²+78(2)+29
C(2) = 4+156+29
C(2) = 189
Since the cost C(x) is in hundreds of dollars, C(2) = 189*100 = $18900
C(2) means that the cost of producing 2 thousand pens is $18,900
For C(4), we are to substitute x = 4 into the given function;
C(4) = 4²+78(4)+29
C(4) = 16+312+29
C(4) = 357
Since the cost C(4) is in hundreds of dollars, C(4) = 357
C(4) means that the cost of producing 4 thousand pens is $35,700
C(x) = x^2 + 78x + 29 models the cost to produce x thousand pens. Calculating C(0), C(2), and C(4), we find that C(0) = 29, C(2) = 189, and C(4) = 357. These values represent the cost in hundreds of dollars for producing 0, 2, and 4 thousand pens, respectively.
To find and interpret C(0), C(2), and C(4), we substitute the given values of x into the function C(x).
1.For C(0), we substitute 0 into the function C(x):
