The ratio of length to width in a rectangle is 2:3. Find the length of the rectangle when area is 150in^3.
Show a quadratic model
Answer:
[tex]\fbox{length= 10 \: in}
[/tex]
Step-by-step explanation:
Given:
Length to Width Ratio = 2:3
Area of Rectangle= 150 in²
To find:
Length of rectangle=?
Solution:
Assume the length of rectangle is 2x
and the width of rectangle is 3x
Now,
we know that,
[tex]\sf\: Area \: of \: Rectangle = Length \times Width \\ \sf \: 150 = 2x \: \times 3x \\ \sf \: 150 =6 {x}^{2} \\ \sf \: {x}^{2} = \frac{150}{6} \\ \sf {x}^{2} = \cancel\frac{150}{6} \\\sf {x}^{2} = 25 \\\sf \sqrt{ {x}^{2} } = \sqrt{ {25} } \\ \sf \sqrt{ {x}^{2} } = \sqrt{ {5}^{2} } \\ \sf \: \fbox{x = 5 \: in}[/tex]
Substituting the value of x in assumption,
[tex] \sf \: length= 2x \\ \sf \: length= 2 \times 5 \\ \sf \: \fbox{length= 10 \: in}

Answer:
| Drink (x ml) | 200 | 100 | 500| 1000|
| Sugar (y g) | 20 | 10 | 50 | 100 |
Step-by-step explanation:
Formula : y=k/x
Solve:
Before we find the answer chart =
| Drink (x ml) | 200 | 100 | 500| 1000|
| Sugar (y g) | 20 | ? | ? | ? |
20 = ? / 200
? = 10
Thus,
100/10 = 10
500/10 = 50
1000/10 = 100
So the chart now is:
| Drink (x ml) | 200 | 100 | 500| 1000|
| Sugar (y g) | 20 | 10 | 50 | 100 |

Answer:
[tex]\displaystyle \cos x \left(\csc x + \tan x\right) = \cot x + \sin x[/tex]
Step-by-step explanation:
We want to simplify:
[tex]\displaystyle \cos x \left(\csc x + \tan x\right)[/tex]
Recall that csc x = 1 / sin x and tan x = sin x / cos x. Substitute:
[tex]\displaystyle = \cos x \left(\frac{1}{\sin x} + \frac{\sin x }{\cos x}\right)[/tex]
Distribute:
[tex]\displaystyle = \frac{\cos x}{\sin x} + \frac{\cos x \sin x}{\cos x} \\ \\ \\ = \frac{\cos x}{\sin x} + \sin x[/tex]
Recall that cot x = cos x / sin x. Hence:
[tex]\displaystyle = \cot x + \sin x[/tex]
In conclusion:
[tex]\displaystyle \cos x \left(\csc x + \tan x\right) = \cot x + \sin x[/tex]

What is the missing number in the following series?
12, 144, 16, ?, 20, 324
Answer:
234
Step-by-step explanation:
The profit of a company , in dollars, is the difference between the company's revenue and cost. The cost C(x) and revenue, R(x) are functions for a particular company The x represents the number of items produced and sold to distributors
The maximum profit that the considered company can get is 142,400 bucks. That profit is earned when input x (the number of items produced) is 380
How to obtain the maximum value of a function?To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.
Putting those values of x in the second rate of function, if results in negative output, then at that point, there is maxima. If the output is positive then its minima and if its 0, then we will have to find the third derivative (if it exists) and so on.
The missing part of question is:
" [tex]C(x)=2000+70x[/tex], [tex]R(x)=830x-x^2[/tex]
A. Determine the maximum profit of the company.
B. Determine the number of items that must be produced and sold to obtain the maximum profit"
The profit is the difference between the revenue and the cost, so we get:
[tex]P(x) = R(x) - C(x) = 760x - x^2 - 2000[/tex]
Finding its first and second rate with respect to x:
[tex]P'(x) = 760 -2x\\P''(x) = -2[/tex]
Equating first rate to 0 to get the critical values:
[tex]P'(x) = 0 \implies 760 = 2x \implies x = 380[/tex]
The second rate is < 0 for any x, x = 380 is minima, and x = 380 being only critical value, it is global maximum.
At x = 380, the profit evaluates to:
[tex]P(x) = 760x - x^2 - 2000\\P(380) = 760(380) - (380)^2 - 2000 = (380)^2 - 2000\\P(380) = 142400[/tex]
Thus, the maximum profit that the considered company can get is 142,400 bucks. That profit is earned when input x (the number of items produced) is 380

In this question we must apply the following set of algebraic properties to simplify a given expression:
[tex]x^{m/n} = \sqrt[n]{x^{m}} = \left(\sqrt[n]{x}\right)^{m}[/tex] (1)
[tex]x^{m+n} = x^{m}\cdot x^{n}[/tex] (2)

At 8 a.m. Anne left Austin and headed south at 20 mph. At 10 a.m. Gene left from the same place and headed south on the same road. If Anne was 10 miles ahead by 4 p.m. on the same day, what was Gene's speed in mph
Using proportions, it is found that Gene's speed was of 25 miles per hour, as he was 30 miles faster over a period of 6 hours.
What is a proportion?A proportion is a fraction of a total amount.
At 8 a.m. Anne left Austin and headed south at 20 mph, hence when Gene left at 10 a.m., she was 40 mph ahead.
At 4 p.m., that is, 6 hours after Gene left, the distance was of 10 miles, that is, Gene was 30 miles faster in 6 hours, so the difference in the speeds is given by:
d = 30/6 = 5 mph.
Since Anne's speed is of 20 mph, Gene's is given by:
v = 20 + 5 = 25 mph.
