A company models its net income, in thousands of dollars, with the function f(x)=9x2−54x−144 , where x is the number of units of its product sold. How many units of its product does the company need to sell in order for the net income to equal $0?
The company needs to sell 8 units in order for the net income to equal $0
The net income function is given as:
[tex]f(x) = 9x^2 - 54x - 144[/tex]
When the net income is 0, then f(x) = 0.
So, we have:
[tex]9x^2 - 54x - 144 = 0[/tex]
Divide through by 9
[tex]x^2 - 6x - 16 = 0[/tex]
Expand the above equation
[tex]x^2 +2x- 8x - 16 = 0[/tex]
Factorize the above equation
[tex]x(x +2)- 8(x + 2) = 0[/tex]
Factor out x + 2 in the above equation
[tex](x - 8)(x + 2) = 0[/tex]
Split and solve for x
[tex]x = 8[/tex] or [tex]x =-2[/tex]
The units of product cannot be negative.
So, the value of x is [tex]x = 8[/tex]
Hence, the company needs to sell 8 units

7 grade math Area of compound figures with triangles, semicircles, and quarter circles
Answer:
area = 250.04 km^2
Step-by-step explanation:
In the image, we have the next figures.
One quart of a circle, with radius R = 12km
A large rectangle, with length L = 13km and width = 9 km
(to find the width of this rectangle, look at the bottom, we have a part of 5km, and then we have the small rectangle with a width of 4km, then 4km + 5km = 9km)
And finally, a smaller rectangle with length L = 5km and width W = 4km
Now, the general rules for each figure are:
The area of a circle of radius R, is
A = pi*R^2
with pi = 3.14
Here we have the fourth part of a circle with a radius R = 12km
Then the area of that part is:
area = (1/4)*3.14*(12km)^2 = 113.04 km^2
And the area of a rectangle of length L and width W is:
A = W*L
Then, the area of the larger rectangle is:
A' = 9km*13km = 117 km^2
And the area of the smaller rectangle is:
A'' = 4km*5km = 20km^2
The complete area of the figure is:
area = A + A' + A'' = 113.04 km^2 + 117 km^2 + 20km^2 = 250.04 km^2
Solve the system of equations.
A. (3,2)
B. (-2,0)
C. (0, -2)
D. (-4,2)
Answer:
d. (-4,2)
Step-by-step explanation:
Here, Y = 1/2X + 4
Or, –5/4X – 3 = 1/2X + 4 (From equation 1 and 2)
Or, –5/4X = 1/2X + 4 + 3
Or, –5/4X = 1/2X + 7
Or, 1/2X + 7 = –5/4X
Or, 7 = –5/4 X – 1/2 X
Or, –5/4X – 2/4 X = 7
Or, –7/4 X = 7
Or, –7 X = 7 × 4
Or, –7X = 28
Or, X = 28/–7
Or, X = – 4
Here, in the fourth option, we can see that X= –4, Hence Option D— (-4,2) Is correct.

Nico practiced drums 1.5 fewer hours than he practiced piano. If Nico practiced the piano for 4 hours, how many hours did Nico practice the drums
Answer:
2.5 hours
Step-by-step explanation:
4 - 1.5 = 2.5
You must subtract 1.5 from the amount of hours he plays piano, which is 4. This is because he spends 1.5 hours less playing drums than he does playing piano.
Michael has $12.50 to buy school supplies. He spends $3.49 at one store for a package of glue sticks, but he still needs to buy 4 pens and a notebook. At the next store, he finds pens for $1.49 each.
Part A
What is the most he can spend of a notebook if he buys the 3 pens?
Part B
On a number line, the solution to Part A would have a circle at __________ that is __________ and the number line would be shaded __________.
Answer: Part A- $ 4.54
Step-by-step explanation:
Answer:
Part A: If he's buying 3 pens he'll have $4.54 left, if he's buying 4, he'll have $3.05 left. I don't really understand what you mean with Part B but I hope this answer and explanation for Part A helps you :D
Step-by-step explanation:
3 Pens situation:
12.50 - 3.49 = 9.01
1.49 (The price of a single pen) x 3= 4.47
9.01- 4.47= 4.54.
.......................................4 Pens situation:
12.50 - 3.49 = 9.01
1.49 (The price of a single pen) x 4= 5.96
9.01- 5.96= 3.05.
A triangular tent has a base of 20 feet , a height of 7 feet and a length of 10 feet . what is the volume of the tent

Algebra homework jimthompson
Answers:
B) 66%C) 34%See the diagram belowC) 86% of the people who studied passed the quiz.===================================================
Explanations:
Problem 1
We have B = 62+32 = 94 people who wear a belt. Of this total, A = 62 belt wearers also have a watch. So A/B = 62/94 = 0.6596 = 65.96% = 66% of the belt wearers have a watch. This value is approximate.
-------------------------------
Problem 2
In the previous problem we found that roughly 66% of the belt wearers have a watch. This must mean about 100% - 66% = 34% of the belt wearers do not have a watch.
-------------------------------
Problem 3
The question is "Among left handers, what proportion has neat handwriting?" which means we're effectively only concerned with the first row that says "left-handed". In this row, there are 5 who write neat, and 10 who do not. We have B = 5+10 = 15 people who are left-handed. We'll divide everything in this row by this value of B.
So for A = 5, it turns into the approximate proportion A/B = 5/15 = 0.33 meaning that about 33% of the left-handers have neat handwriting.
For the other value in this row, A = 10 turns into A/B = 10/15 = 0.67 = meaning that about 67% of the left-handers have messy hand writing.
You'll do the same thing for row 2, but you'll divide everything by B = 65 (because there are 34+31 = 65 right-handed people total).
The filled out table is shown below.
-------------------------------
Problem 4
Let's say we ignore the percentage signs. Adding the values across the first row gets us B = 86+14 = 100 people who passed the quiz. Of that, A = 86 people who passed also studied as shown in the top left corner.
We can then see that A/B = 86/100 = 86% of the people who passed the quiz also studied. Notice the phrasing here. It's not the other way around. We would not say "86% of the people who studied passed the quiz". Your teacher has the order swapped unfortunately. If choice C said "86% of the people who passed the quiz studied for the test", then it would be fully correct. However, I think that's what they were going for and made a typo.
If we did state that "86% of the people who studied passed the quiz", then we'd be considering the first column instead of the first row. However, note how the percentages in the first column do not add to 100%.
