Answer 1
Answer: 18) 
It says the scale factor is 1:25000, so for every one part there is actually 25000. So for every centimeter, there is actually 25000 cm. See that we multiplied by 25000. 
So for 6.8cm, multiply by 25000 to get 170000cm. 
The real distance represented is 170000cm.

19) Just work out one step at a time using order of operations. 
Do parentheses first. 7^2 = 49, and 3^3 is 3*3*3 which is 27. 
Now you have [8(49 - 27) ]/ sqrt121. 

Finish simplifying the parentheses. 49 - 27 is 22.
[8(22)] / sqrt121.

Now multiply 8 times 22, which is 176.
176 / sqrt 121 

The square root of 121 is 11.

176/11.
= 16
Answer 2
Answer: #18).

-- The map has a scale factor of 1:25,000.

-- Any distance on the paper map represents
25,000 times that distance in the real world.

-- If you measure 6.8 cm on the paper map,
that represents a real distance of    (25,000 times 6.8 cm).


#19).  Relax, breathe, and take it one step at a time:

=>  7² = 49
=>  3³ = 27
=> (7² - 3³) = (49 - 27) = 22
=>  8 times that is  176 .

√121  =  11 .

Can you handle it from there ?

Kesara Santiago purchased a riding mower for $2,746.00. She received a $49.95 rebate from the manufacturer and a $38.95 rebate from the store. What is the final price?

Answers

Answer: $2657.1

Step-by-step explanation:

Given: The price of a riding mower = $2,746.00

The amount she received by manufacturer as rebate= $49.95

The amount she received by the store as rebate =  $38.95

The total amount she received as rebate =\$49.95+\$38.95=\$88.9

Therefore, the final price of the riding mower is given by :-

\text{Final Price}=\$2746-\$88.95=\$2657.1

$2657.1

2746-49.95-38.95

If i is raised to an odd power, then it can not simplify to be

-1

i

i is the square root of -1. It is an imaginary number because you can't find the answer to the square root of a negative number. 
However, the (square root of a number) squared is that number, for example sqrt4 * sqrt4 = 4. 
Likewise, sqrt(i) * sqrt(i) = -1. You can see it as sqrt(-1) * sqrt(-1) = -1. 

If you multiply by another sqrt(i) however, sqrt(i)^3, then the last sqrt(i) will be left and there will still be an imaginary number. You will have -1 * i, which is -i. 
However, if you have sqrt(i)^4, then you have sqrt(-1)*sqrt(-1)*sqrt(-1)*sqrt(-1), which is -1*-1, which equals 1. You see that pairs of sqrt(i)'s balance and take out imaginary numbers. 

So, sqrt(i) to odd powers will still have imaginary numbers, while sqrt(i) to even powers won't have imaginary numbers.

​​​Find the equations of the vertical asymptotes of the given rational function f(x)=(x²+9x)(x²-2x-15)

Answers

To find the vertical asymptotic equations of the rational function, we must first find the points of intersection of the function with the x-axis. These points are the solutions of the equation f(x) = 0. We decompose the exponential function into the product of two expressions: f(x) = (x² + 9x)(x² - 2x - 15) Now we can set each of the expressions inside the parentheses equal to zero and solve the vertical asymptotic equations: x² + 9x = 0 or x² - 2x - 15 = 0 To solve the first equation, we can factor x out: x(x + 9) = 0 So the two vertical asymptote equations are x = 0 and x + 9 = 0 (that is, x = -9). To solve the second equation, we can use the analysis method or the quadratic formula. Using the analysis method, we can decompose the expression x² - 2x - 15 in the following form: (x - 5)(x + 3) = 0 Therefore, two vertical asymptote equations equal to x - 5 = 0 (that is, x = 5) and x + 3 = 0 (that is, x = -3). So the vertical asymptotic equations of the rational function f(x) = (x² + 9x)(x² - 2x - 15) are equal to x = 0, x = -9, x = 5 and x = -3.

—1(-4)+-2(3)(-4)-(-6-10)

Answers

Answer:

To simplify the expression —1(-4) + -2(3)(-4) - (-6-10), let's break it down step by step:

1. Start by simplifying the multiplication in the expression:

—1(-4) equals 4

-2(3)(-4) equals 24

-6-10 equals -16

2. Now substitute the simplified values back into the original expression:

4 + 24 - (-16)

3. To solve this expression, we need to address the double negative:

When we have a negative sign before a negative number, it becomes positive. So, -(-16) becomes +16.

4. Now, we can continue evaluating the expression:

4 + 24 + 16

5. Finally, add the numbers together to get the answer:

4 + 24 + 16 = 44

Therefore, the value of the expression —1(-4) + -2(3)(-4) - (-6-10) is 44.

Find the value of x and RT if RS=24 cm

Answers

RS = RT + TS = 24 cm

Let's plug our values into the equation above

24cm = 6x - 4 + 10cm

Combine like terms

24 cm = 6x + 6 cm

Subtract 6 cm from both sides

18 cm = 6x

Divide both sides by 6

3 = x

Plug 3 into the expression for RT

RT = 6(3) - 4 = 18 - 4 = 14 cm

Similarly, we know that TS = 10 cm and RS = 24 cm

24 cm - 10 cm = 14 cm

RT = 14 cm

14 cm = 6x - 4

Add 4 to both sides

18 cm = 6x

Divide both sides by 6

3 = x
