a and b are positive integers and a-b=2. Evaluate the following:

9^1/2b/3^a

**Answer:**

[tex] \frac{1}{ 9 }[/tex]

**Step-by-step explanation:**

[tex] \huge \frac{ {9}^{ \frac{1}{2}b } }{ {3}^{a} } \\ \\ = \huge \frac{ {( {3}^{2} )}^{ \frac{1}{2}b } }{ {3}^{a} } \\ \\ = \huge \frac{ { {3}}^{2 \times \frac{1}{2}b } }{ {3}^{a} } \\ \\ \huge = \frac{ {3}^{b} }{ {3}^{a} } \\ \\ \huge = \frac{1}{ {3}^{a - b} } \\ \\ \huge= \frac{1}{ {3}^{2} } \\ ( \because \: a - b = 2)\\ \\ \huge = \frac{1}{ 9 }[/tex]

The **evaluation **of the **expression **9^((1/2)b)/3^a is 1/9

If we have a^b then 'a' is called **base **and 'b' is called** power** or **exponent **and we call it "a is **raised **to the **power **b" (this **statement **might change from text to text slightly).

**Exponentiation**(the process of raising some number to some **power**) have some **basic rules **as:

[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]

Now, for this case, we are given that:

a - b = 2

The **expression **is:

[tex]\dfrac{9^\dfrac{1}{2}b}{3^a}[/tex]

Since we know that [tex]3^2 = 9[/tex], thus:

[tex]\dfrac{9^{\frac{1}{2}b}}{3^a} = \dfrac{(3^2)^{\frac{1}{2}b}}{3^a} = \dfrac{3^{2 \times 1/2 \times b}}{3^a} = \dfrac{3^b}{3^a} = \dfrac{1}{3^{a-b}}[/tex]

Since a-b = 2, therefore, we get:

[tex]\dfrac{9^{\frac{1}{2}b}}{3^a} =\dfrac{1}{3^{a-b}} = \dfrac{1}{3^2}} = \dfrac{1}{9}[/tex]

Thus, the **evaluation **of the **expression **9^((1/2)b)/3^a is 1/9

**Answer:**

∠A = 6x + 4

**Step-by-step explanation:**

Hello There!

We are given the exterior angle ∠ACD and an interior angle ∠B

If you didn't know this is the rule for exterior angles of a triangle:

An exterior angle is equal to the sum of its opposite interior angles

so ∠ACD = ∠A + ∠B ( ∠A and ∠B being the opposite interior angles)

So with the information that we are given we plug them into their corresponding angle

then we would have

8x+5 = ∠A + 2x + 1

now we solve for A

Well how do we solve for A?

Well we have to isolate the variable

To do so we want to get rid of 2x + 1

We do that by subtract each side by 2x and 1

8x + 5 - (2x + 1 ) = 6x + 4

we're left with

∠A = 6x + 4

What is the domain and range for function A?

**Answer:**

**Domain → (-∞, ∞)**

**Range → (-∞, 5)**

**Step-by-step explanation:**

Domain of a function is a set of x-values (input values) for which the function is defined.

Function A is a quadratic function (in the form of a parabola) opening downwards.

This function is defined for every input value from negative infinity to positive infinity.

Therefore, **domain of the given function A is (-∞, ∞)**.

Similarly, y-values (output values) vary from negative infinity to 5.

Therefore, **range of the given quadratic function will be (-∞, 5).**

y=−x+2 y=3x−4 khan

Answer: 0

Step-by-step explanation:

2y -3x - 4 = 0

Subtract 2y from both sides of the equation.

-3x - 4 = -2y

Add 4 to both sides of the equation.

-3x = -2y + 4

Divide each term by -3 and simplify

**Step-by-step explanation:**

The fare for taxi journeys in a certain town is $2.00 plus $1.00 for each kilometre. Using this information, estimate: (i) The fare for a journey of 3.5 km. (ii) The distance travelled if the fare was $6.00

**Answer:**

**Step-by-step explanation:**

Since the journey initially costs $2 (this will be our y-intercept), and the variable (x) is $1 for every additional kilometer. This can be modelled as...

y=1x+2

(i) if we want to know the cost of what 3.5 km would cost, we simply plug it into our equation...

y=1(3.5)+2

Answer: $5.5

(ii) For this question you can set the y value equal to 6 and plug in a random number for x until you get 6 on both sides. In this case...

6=1x+2

6=1(4)+2

The distance traveled if the fare was $6 is 4km

Evaluate:

Σ18/1 (5n– 4) = [? ]

Basically, you are going to evaluate 5n - 4 from n = 1 to n = 18. Don't forget to add as you evaluate.

I will get you started.

Let n = 1 and then n = 2.

5(1) - 4 + 5(2) - 4 + the rest

5 - 4 + 10 - 4 + the rest

1 + 6 + the rest

7 + the rest

Just continue the pattern. You will then let n be 3, 4, 5, etc all the way to 18.

Given the vertex of a parabola is (-3,1) and also contains the point (-4,-1). State the exact equation of the parabola in vertex form, show all your work.

**Answer:**

**y = -2(x + 3)^2 - 1**

**Step-by-step explanation:**

The vertex equation of a parabola is y = a(x - h)^2 + k. If the vertex here is (-3, 1), then this equation becomes y = a(x + 3)^2 + 1.

Knowing that the graph passes through (-4, -1), we let y = -1 and x = -4, obtaining:

-1 = a(-4 + 3)^2 - 1, which must be solved for a:

-1 = a - 1. Therefore, a = -2, and the exact equation of this parabola is:

**y = -2(x + 3)^2 - 1**

The sum of two numbers is 52 . The larger number is 2 less than twice the smaller number .What are the numbers

Answer:

35.34 and 16.66

Step-by-step explanation:

Given data

let the numbers be x and y

the smaller number = x

the larger number = y

x+y=52--------1

*The larger number is 2 less than twice the smaller number*

y=2x-2-------2

put y= 2x-2 in eqn 1

x+2x-2=52

3x-2=52

3x=52-2

3x=50

x= 50/3

x= 16.66

put x=16.66 in eqn 1 to find y

x+y=52

16.66+y= 52

y=52-16.66

y= 35.34

Hence the numbers are

35.34 and 16.66

**Check**

35.34+16.66= 52

Avery deposited 1250 in a new savings account. Which amount is closest to the balance of the account at the end of three years

**Answer: $1,467.80**

**Step-by-step explanation:**

The formula for the future value given annual compounding is:

= Amount * ( 1 + rate) ^ number of years

The amount after 3 years at 5.5% is therefore:

= 1,250 * ( 1 + 5.5%)³

= 1,250 * 1.174241375

**= $1,467.80**

ESSAY: POLITICAL NEWSOBJECTIVESConstruct a model government to solve a current political issue. Remember that political science is the study of who gets what, when, and how. The world is filled with current news stories regarding how one political system or another handles conflict. For this assignment, select some current news stories that have to do with politics, government decisions, or local problems that may require debate or a vote. You should also use outside reading material or online resources to find older events in history that are similar to the current news stories you found. Your task will be to write an essay and include a diagram of a government model. Your essay will compare the current news story to a similar event in history and how the government dealt with that issue. You will then create a government model and write about how you would address the current issue in your own way. When creating your government model make sure to identify what the input and outputs are. In your essay, you will also provide a diagram representing your form of government according to Aristotle's: rule of one, rule of a few, or rule of many. To help you in your research and planning, think about a key issue that is in the news today. How is it being handled? Has anything similar to this happened in the past? Was that handled in the same way? Was it managed differently? Have other countries been faced with this problem? Do all governments approach this conflict in the same manner? These questions can help guide you during your research and writing process.
