What property is this an example of 56 + 82 = 82 + 56?

Answer:

Step-by-step explanation:

Complementary angles are two angles that add up to be 90 degrees.

We can write an equation and solve for x.

(3x - 4) + (5x + 6) = 90

~Combine like terms

8x + 2 = 90

~Subtract 2 to both sides

8x = 88

~Divide 8 to both sides

x = 11

Angle DEF:

3x − 4

3(11) - 4

33 - 4

29°

Angle FEG:

5x + 6

5(11) + 6

55 + 6

61°

Check:

29 + 61 = 90°

Best of Luck!

Where are the answer choices?

Still, it's possible to help you without your having shared those choices.

The "difference quotient" is defined as:

 f(x + h) - f(x)

--------------------

           h

where h represents an incremental (small) change in x.

Here f(x) = 3 - log x, and so f(x + h) = 3 - log (x + h).

Therefore the difference quotient is:

{3 - log (x + h)} - {3 - log x}

-------------------------------------

                    h

This can be simplified.  In the numerator we have 3 - 3, so the numerator simplifies to -log (x + h) + log x

and the difference quotient is

-log ( x + h) + log x

---------------------------

              h

This can be rewritten as

log x - log (x + h)                                x                                  x

--------------------------- , or (1/h)*log ------------ , or  (1/h) log { ----------- }

              h                                       (x + h)                            x + h          

Answer:

B

Step-by-step explanation:

I guessed and got it right.

The equation is already in standard form since standard form is

ax^2+bx+c = 0

Here we have

a = -3

b = 4

c = -2

Answer: 24100

Step-by-step explanation:

The money in the account after 8 years is $24068.631.

Given that, principal=$19000 and the rate of interest=3%.

The formula to find the compound interest is CI=A-P.

Where, A=Amount that is [tex]A=P(1+\frac{r}{100} )^{n}[/tex], P=principal.

Now, [tex]A=19000(1+\frac{3}{100} )^{8}[/tex]

=19000[tex](1.03)^{8}[/tex]

=19000×1.26677008139

=$24068.6315464

=$24068.631

Therefore, the money in account is $24068.631.

Hope This Helps :)

The required rate for granola in dollars per pound is 1.25.

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

Given that,

The total money spent on granola is $3.75.

And, the amount of granola is 3 pounds.

The unit rate for the given case can be found using unitary method as,

Money spent for 3 pounds = $3.75

Then, money spent for 1 pound = 3.75/3 = $1.25

Hence, the rate of granola $1.25 per pound.

Answer:

The expression are

        [tex]\Delta E  = \Delta E _1 + \Delta E_2[/tex]

and

     [tex]\Delta E  = \Delta E _3 + \Delta E_4[/tex]

Step-by-step explanation:

Generally from the diagram  the energy change from state A to  state B is  

        [tex].\  \ \Delta E_2 \ \ \ \ \  \  \ \ \Delta E_2  \\A  \ \ \to \ \ \  C \ \ \ \to \ \ \  B\\[/tex]

Also  

[tex].\  \ \Delta E_3 \ \ \ \ \  \  \ \ \Delta E_4  \\A  \ \ \to \ \ \  D \ \ \ \to \ \ \  B\\[/tex]

So  two expressions for the difference in internal energy between state a and state b are  

      [tex]\Delta E  = \Delta E _1 + \Delta E_2[/tex]

and

     [tex]\Delta E  = \Delta E _3 + \Delta E_4[/tex]
