Scientific notation of 48200
Answer:
4.82 × 10^4
Step-by-step explanation:
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]
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]

Help me, please! I need help with this.
Answer:
x = 9
Step-by-step explanation:
Because the angles are vertical angles their measures are congruent so make them equal to each other:
3x -8 = 2x +1 subtract 2x from both sides
-2x -2x
x -8 = 1 add 8 to both sides
+8 +8
x = 9

−2x=x2−6 Rewrite the equation by completing the square.
Answer:
(x + 1)² = 7
Step-by-step explanation:
Given:
-2x = x² - 6
We'll start by rearranging it to solve for zero:
x² + 2x - 6 = 0
The first term is already a perfect square so that's fine. Normally, if that term had a non-square coefficient, you would need to multiply all terms a value that would change that constant to a perfect square.
Because it's already square (1), we can simply move to the next step, separating the -6 into a value that can be doubled to give us the 2, the coefficient of the second term. That value will of course be 1, giving us:
x² + 2x + 1 - 1 - 6 = 0
Now can group our perfect square on the left and our constants on the right:
x² + 2x + 1 - 7= 0
x² + 2x + 1 = 7
(x + 1)² = 7
To check our answer, we can solve for x:
x + 1 = ± √7
x = -1 ± √7
x ≈ 1.65, -3.65
Let's try one of those in the original equation:
-2x = x² - 6
-2(1.65) = 1.65² - 6
- 3.3 = 2.72 - 6
-3.3 = -3.28
Good. Given our rounding that difference of 2/100 is acceptable, so the answer is correct.

If Matt earns eight dollars per hour and h is the number of hours Matt works, which expression represents how much money Matt earns?
Answer:
8(h)=x
Step-by-step explanation:
Matt earns 8 dollars for every hour he works. So you multiply the total numbers worked (h) by 8. That will give you the amount of money he's made(x) so the equation would be 8(h)=x
36/2^5 over 8+7x(3+11)
Answer:
119.25
Step-by-step explanation:
36/32 simplified is 9/8.
8 + 7(3+11), I'm assuming it's not x.
8 + 7(14) = 106
(9/8)/106 = 9/8*106 = 954/8 = 119.25

A certain television is advertised as a 10-inch TV (the diagonal length). If the width of
the TV is 6 inches, how many inches tall is the TV?
Answer:
8 in
Step-by-step explanation:
Given data
DIagonal= 10 in
Width= 6 in
`Height=???
We know that the expression that can be used to find the missing dimension is given as
d^2= w^2+h^2
substitute
10^2=6^2+h^2
100= 36+h^2
100-36= h^2
64= h^2
h= √64
h= 8 in
Hence the height is 8 in

70 is what percent of 56
Answer:
70 is 125% of 50
Step-by-step explanation:
I hope this helped :)
The percentage value of 70 to 56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.
Given that, to find what percent of 70 in 56.
To find out if the percentage of 70 is 56, follow the steps:
Step 1:Find the ratio of the two numbers that is the ratio of 70 and 56 gives:
[tex]70:56 = 70/56[/tex]
Divide both numerator and denominator by 14 yields in:
[tex]= 5/4[/tex]
Step 2: Convert the result of step 1 into decimals by a long division of 5 by 4.
[tex]5/4 = 1.25[/tex]
Step 3: Find the percentage value of the decimal by multiplying the decimal by 100.
[tex]1.25 \times100 = 125[/tex]%
Therefore, the percentage value of 70 to 56 is 125% by taking the ratio of 70 to 56 and then converting it to a percentage.
