There are many times in algebra when you need to simplify an expression. understanding of these properties to make the problems in algebra easier to Pour 12 ounces of coffee into mug, then add splash of milk.

following ways:

Pour 12 ounces of coffee into mug, then add splash of milk.

Add a splash of milk to mug, then add 12 ounces of coffee.

The order that you add ingredients does not matter. In the same way, it does not matter whether you put on your left shoe or right shoe first before heading out to work. As long as you are wearing both shoes when you leave your house, you are on the right track!

Gnoma [55]

Answer:

Step-by-step explanation:

A is missing a combination AR and has repeats such as AG and GA. Since the order of the sides doesn't matter, AG and GA are the same thing.

C is missing many combinations, it only has 4

D has two of the same sides. The question states "you can choose two <em>different </em>sides" so something like AA is not an option

We can use the process of elimination to conclude the answer is B.

What is the value of y?<br> Enter your answer in the box.<br><br> y=

Mashcka [7]

Answer:

64 degrees

Step-by-step explanation:

The interior angles of a triangle must add up to 180 degrees. So, we can add up the other two, known angles to get 116. Subtract 116 from 180 (180-116) to get 64.

DEFINITION: Besting: the clockwise totation (0° to 360°) from North to any line.

A) Calculate the bearings of D from A:

bearings of D from A =x

looking the picture:

x=48°+55°+180°

x+103°+180°

x=283°

B)Calculate the bearings of A from C:

bearings of A from C =y

180°+55°=y

y=235°

C) Calculate the distance between A and B:

The angle in B is 74° (Because 55°+51°+74°=180°)

Using the Law of sines:

$\frac{19}{sin(74)} =\frac{AB}{sin(51)} \\\\AB=19sin(51)sin(74)\\AB=14,2\\\\$

D)Calculate the distance between D and C:

Using the Law of cossines:

$DC^{2} =27^{2} +19^{2} -2*27*19*cos(48)\\DC=20,09$

E) A Helicopter is hovering at A at a height of 2.5Km, find angle of elevation of helicopter from C:

If log (m + n) = log m+log n, show that m =n/n-1

Sedbober [7]

log (m + n) = log m+ log n and proved it m =n/n-1

Given;

If log (m + n) = log m+ log n

To show that the m =n/n-1

Now, According to the question:

We know that,

Log (m + n) = log m + log n

Log (m + n ) = log (mn). [log a + log b = log ab ]

Cancelling the log on both sides.

then,

m + n = mn

=> n = mn - m

=> n = m (n - 1)

=> m = n / n - 1

Hence Proved

log (m + n) = log m+ log n and proved it m =n/n-1

What is Logarithm?

A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2.

The statement that is true about the function is D. it is discontinuous and non-differentiable at x = 3.

<h3>How to determine which statement is true?</h3>

To determine which statement is true, we need to know the conditions for continuity and differentiablity of a function.

<h3>Conditions for continuity and differentiablity of a function.</h3>

For a function f(x) to be continuous at a point x = a, then both the left hand limit of f(x) and the right hand limit of f(x) as x → a must be equal. That is $\lim_{x \to a^{-} } f(x) = \lim_{x \to a^{+} } f(x)$ . So, $\lim_{x \to a^{} } f(x)$ must exist since $\lim_{x \to a^{-} } f(x) = \lim_{x \to a^{+} } f(x) = \lim_{x \to a^{} } f(x)$

Also, for a function to be differentiable at a point x = a, it must also exist at x = a

So, since f(x) = {x² - 1 if -1 ≤ x ≤ 3 and x²/3 if 3 < x ≤ 8}

From the equality on the first condition,we see that f(x) is exists at x = 3 but is not continuous since f(x) changes to another function when x > 3. So,left hand limit of f(x) and the right hand limit of f(x) as x → 3 are not equal.

That is $\lim_{x \to 3^{-} } f(x) \neq \lim_{x \to 3^{+} } f(x)$ . Thus, the function is discontinuous at x = 3.

For differentiability, both conditions must be met. Since only one condition is met, it is non-differentiable.

So, the function is discontinuous and non-differentiable at x = 3.

So, the statement that is true about the function is D. it is discontinuous and non-differentiable at x = 3.
