Answer:
The last table given See attached image)
Step-by-step explanation:
Notice that they are asking for the inverse function to the one with the detailed relationship given. The original relationship was assigning to the Domain of number of people attending, the Range of values for charges.
Therefore, the inverse function will be assigning in the opposite way: from the average charges (now the Domain of this relationship), to the number of people attending (now the Range of this relationship). The relationship should also maintain the original element to element connection:
What was:
(20, $10) should now be ($10, 20)
(26, $6.25) should now be ($6.25, 26)
(35, $4) should now be ($4, 35)
This is exactly represented by the last table (see also image attached)
Answer: 95 units.
Step-by-step explanation:
The cost of making x units is:
C(x) = x^2 + 10*x + 45.
Now, if the cost is $10,020, then we can solve this for x as:
C(x) = 10,020 = x^2 + 10*x + 45
x^2 + 10*x + 45 - 10,020 = 0
x^2 + 10*x - 9,975 = 0
Now, remember that for a quadratic equation:
a*x^2 + b*x + c = 0
the solutions are:
In this case the solutions are:
x =
Then we have two solutions, one for each sign:
x = (-10 -200)/2 = -110
x = (-10 + 200)/2 = 95
Here we must choose the positive option, as x represents a positive quaintity.
Then the number of units manufactured is 95.
Answer:
I would say B because there are 15 1s
Answer:
43,-16,20,-8,an -12
Step-by-step explanation:bcz i think the patteren is they all equal evan numbers an all those numbers give u even numberswhen u do the math aginst -12.. hope it helps!
Use the data in the given table for #4 to find the slope of the line through these four points. I did this this way:
5-3 2
m = -------- = ---- = 1/2
12-8 4
Now use y = mx + b to determine the y-intercept:
Borrowing the coefficients (0,0) from the table,
0 = (1/2)(0) + b. Thus, b = 0, and y = (1/2)x (answer)
