if
[tex]a = \frac{2x + \sqrt{x} }{x} [/tex]
and
[tex]b = \frac{1 - 2 \sqrt{x} }{ \sqrt{x} } [/tex]
without sing a calculator, show that
[tex](a + b) {}^{2} = \frac{4}{x} [/tex]
Answers
Answer:
Step-by-step explanation:
Rationalize the denominator of b. So, multiply the numerator and denominator by [tex]\sqrt{x}[/tex]
[tex]b = \frac{(1-2\sqrt{x}) *\sqrt{x}}{\sqrt{x}*\sqrt{x} }=\frac{1*\sqrt{x} -2\sqrt{x} *\sqrt{x} }{\sqrt{x} *\sqrt{x} }\\\\=\frac{\sqrt{x} -2x}{x}\\[/tex]
Now, find a +b
[tex]a +b = \frac{2x+\sqrt{x} }{x}+\frac{\sqrt{x} -2x}{x}\\\\=\frac{2x+\sqrt{x} +\sqrt{x} -2x}{x}[/tex]
Combine like terms
[tex]= \frac{2x-2x+\sqrt{x} +\sqrt{x} }{x}\\\\=\frac{2\sqrt{x} }{x}[/tex]
Now find (a + b)²
(a +b)² = [tex](\frac{2\sqrt{x} }{x})^{2}[/tex]
[tex]= \frac{2^{2}*(\sqrt{x} )^{2}}{x^{2}}\\\\= \frac{4* x}{x^{2}}\\\\= \frac{4}{x}[/tex]
Hint: [tex]\sqrt{x} *\sqrt{x} =\sqrt{x*x}=x[/tex]

A sweater is 15% off. The regular price is $24. What is the price after the discount is taken off?
Answers
Answer:
$20.40 after the discount
Step-by-step explanation:
To find 15% of 24, you multiply 24 and 0.15, which gets you 3.6
Then, to find the price after the discount, you subtract the 15% (the 3.6). So, 24 - 3.6 = $20.40

Is a triangle with side lengths of 5, 10, and 15 a right triangle? Explain
Answers
Answer:
No, it is not a right triangle.
Step-by-step explanation:
Using the property of the right triangle, square root (5^2 + 10^2) = 5root(5), and it is not equal to 15, so it is not a right triangle.
c=15, a=5, b=10
15^2=5^2+10^2
225=25+100
225=125
225 is not equal to 125 therefore, this triangle is not a right triangle.

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures cell phones, can be modeled by the polynomial 2x2 + 55x + 10. The cost, in dollars, of producing the cell phones can be modeled by 2x2 – 15x – 40. The variable x represents the number of cell phones sold.
What expression represents the profit, and what is the profit if 240 cell phones are sold?
40x – 30; $2,400
40x – 30; $9,570
70x + 50; $16, 850
70x + 50; $28,800
Answers
Answer:
Given that the equation of the revenue is R=2x2+55x+10 and the equation of the cost is C=2x2 – 15x – 40, you will get the profit by subtracting the revenue from the cost: R-C=P. Therefore, P=(2x2+55x+10)-(2x2 – 15x – 40). You will get P=70x+50 where x is is the number of cellphones sold. If 240 cellphones are sold, then the profit is 16850 dollars.
Step-by-step explanation:
The profit expression is 70x + 50 and the profit if 240 cell phones are sold is $16,850
How to calculate profitRevenue, R = 2x² + 55x + 10Cost, C = 2x² – 15x – 40where,
x = number of cell phones sold.
Profit = Revenue - cost
= (2x² + 55x + 10) - (2x² – 15x – 40)
= 2x² + 55x + 10 - 2x² + 15x + 40
Profit = 70x + 50
If x = 240Profit = 70x + 50
= 70(240) + 50
= 16,800 + 50
= $16,850
