Answer:
M = 3000n(20 - n) dollars.
Step-by-step explanation:
Given that, each machine sets up in one day.
Therefore, n number of machines will take n days to set up.
Now, there are 20 days' time to deliver all the t-shirts.
And the machines are turned on after all the n machines are set up.
So, all the n machines will work for (20 - n) days and producing each machine 200 shirts in one day, then one machine will produce 200(20 - n) number of t-shirts and n machines will produce 200n(20 - n) number of t-shirts in the remaining (20 - n) days.
Now, the selling price for each t-shirt is $15.
Therefore, the total amount of money M she will receive will be, M = 15 × 200n(20 - n) = 3000n(20 - n) dollars. (Answer)
Question 23
Lateral Surface Area = πD x height
Lateral Surface Area = π (4) (6) = 75.40 in²
Question 24
Total Surface Area = 2(8.2 x 3.4) + 2(8.2 x 2) + 2(3.4 x 2)
Total Surface Area = 36.56 in²
Question 25
Total Surface Area = 2(10 x 12) + 2(12 x 4) + 2(10 x 4)
Total Surface Area = 416 in²
The correct answers are: 1/2, 2 and -2.
To get this, factor f(x)
f(x)=2x^3-x^2-8x+4
f(x)= (2x^3-x^2) - (8x -4)
f(x)= (2x-1)(x^2) + (2x-1)(-4)
f(x)= (2x-1)(x^2-4)
f(x)= (2x-1)(x-2)(x+2)
2x-1=0
2x=1
x=1/2
x-2=0
x=2
x+2=0
x=-2
