Answer:

13 units

Step-by-step explanation:

Calculate the distance using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, - 8) and (x₂, y₂ ) = (- 5, 4)

d = [tex]\sqrt{(-5-0)^2+(4-(-8))^2}[/tex]

   = [tex]\sqrt{(-5)^2+(4+8)^2}[/tex]

   = [tex]\sqrt{25+12^2}[/tex]

   = [tex]\sqrt{25+144}[/tex]

   = [tex]\sqrt{169}[/tex]

   = 13

A line parallel to the x-axis is horizontal and thus any point on the line has a fixed y-coordinate. So the given line that passes through (-5, 4) has equation y = 4 with slope 0.

A line perpendicular to this one would be vertical. Its slope would be undefined (or infinite, depending on convention), so that any point on it has a fixed x-coordinate. If this line also passes through (-5, 4), then its equation would be x = -5.

(secx-tanx)(secx+tanx)

=sec^2-tan^2

=1

Answer:

Step-by-step explanation:

LHS = (sec x - tan x)(Sec x - tan x)    

      = sec² x - tan²x         {(a +b)(a-b) = a² - b²}

      [tex]= \dfrac{1}{Cos^{2} \ x}-\dfrac{Sin^{2} \ x}{Cos^{2} \ x}\\\\\\= \dfrac{1-Sin^{2} \ x}{Cos^{2} \ x}\\\\= \dfrac{Cos^{2} \ x}{Cos^{2} \x}\\\\= 1[/tex]

Hence proved.

Answer:

450 per month

Step-by-step explanation:

5000-1400=3600

3600/8=450

Since Peter already has 1400 dollars saved you can subtract that form the total amount and since he is trying to get the rest in eight months you just divide the difference by eight.

Answer:

Solution:

When X=2

f(2)=1/2

= 1/2

When X= 1

f^-1(1)= 2*1

=2

When X=2

f^-1(2)=2*2

= 4

Step-by-step explanation:

I don't know if these are correct and if that last question is f^-1(2) or not.

Answer:

The clown made 109 animal balloons.

Step-by-step explanation:

You'll divide 6 from 654.

654 ÷ 6 = 109

Do long division.

6 goes into 6, 1 time.

6 cannot go into 5 so you'll put 0.

6 can go into 54, 9 times.

109 is your answer.

Answer: -169

Step-by-step explanation:

There are two ways to answer this question, and one is a lot easier than the other. The first is to divide f(x) by g(x) and then substitute 8 for x, which could take a very long time and would be a huge pain.

On the other hand, you can substitute 8 into the equation f(x), and get

f(8) = 3- 2(8) = 3-16 = -13

Then substitute 8 into g(x) and get

g(8) = 1 /(8 +5) = 1/(13)

Then you simply divide the two to get -13/(1/13). Here, you can multiply the numerator and the denominator of the larger fraction by 13, so you would end up with -169/1, or, the answer to your problem: -169.

Step-by-step explanation:

Domain and range are the possible x and y values, a function can take.

For the given functions:

Given that:

[tex]y = x^n[/tex]

When n is even.

Assume that [tex]n=2[/tex]

The equation becomes:

[tex]y =x^2[/tex]

See attachment for the graph of [tex]y =x^2[/tex].

From the graph, we can see that values of x extend to both sides of the x-axis.

So, the domain is: [tex](-\infty, \infty)[/tex]

However, the value of y starts from 0 and the curve opens upward. This means that y only take positive values.

So, the range is: [tex][0, \infty)[/tex]

When n is odd.

Assume that [tex]n =3[/tex]

The equation becomes: [tex]y = x^3[/tex]

See attachment for the graph of [tex]y = x^3[/tex].

From the graph, we can see that values of x and y extend to both sides of the x-axis and y-axis, respectively.

So, the domain is: [tex](-\infty, \infty)[/tex]

The range is: [tex](-\infty, \infty)[/tex]

Hence, option (B) is correct.

I'll do part (a) to get you started. Part (b) will follow the same sort of steps.

In part (a), we have these two points

You can call the points any letters you want. Let's find the slope of line AB

m = (y2-y1)/(x2-x1)

m = (8-2)/(3-(-3))

m = (8-2)/(3+3)

m = 6/6

m = 1

The slope of line AB is 1.

The mirror line will have the negative reciprocal of this slope, so the slope of the mirror line is -1. In other words, the mirror line slope is perpendicular to line AB. We'll use this perpendicular slope later.

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

Next, we find the midpoint of segment AB

Average the x coordinates to get (x1+x2)/2 = (-3+3)/2 = 0/2 = 0

Repeat for the y coordinates:  (y1+y2)/2 = (2+8)/2 = 10/2 = 5

The midpoint of AB is (0,5)

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

The mirror line will have two defining traits

So,

y = mx+b

y = -1x+b ... plugging in that perpendicular slope

5 = -1*0+b .... plugging in (x,y) = (0,5)

5 = 0+b

b = 5

The equation of the mirror line is y = -x+5 as shown in the diagram below. The mirror line is shown in green. Point D isn't important as it's just used to help set up the 90 degree angle.

This wraps up part (a) and I'll let you handle part (b). If you're stuck, then feel free to ask.

Answer:

PROBABILITY=42/80

=7/20

Step-by-step explanation:

Distance = √(x_2 - x_1)² + (y_2 - y_1)²

Distance = √[(-a) - a]² + (b - b)²

Distance = √[-2a]² + (0)²

Distance = √4a²

Distance = 2a

y=3/3x+-2

Step-by-step explanation:

it goes up 3 and over 3 so its 3/3 and it starts at -2

Hi there!

[tex]\large\boxed{y = \frac{3}{4}x - 2}[/tex]

y = mx + b

To find the equation, we can begin by deriving the slope (m):

slope = y2-y1/x2-x1

Find two points:

(0, -2) and (4, 1)

Plug these into the slope equation:

slope = 1 - (-2) / 4 - 0

slope = 3/4

We know that there is a y-intercept of y = -2 (b value), so:

y = 3/4x - 2

Answer:

A(-5,9)

Step-by-step explanation:

Let A(a,b)

Since M is the midpoint then of A(a,b) and B(3,-5) then

M( (a+3)/2 , (b-5)/2)

But it is given that M(-1,2)

So (a+3)/2 = -1 which implies a=-5

and (b-5)/2=2 which implies b=9.

Therefore A(-5,9)

Answer: 6 essays

Step-by-step explanation:

With the given question, we can write out an equation.

Equation: 3(1000)+2000x=15000

We have 3(1000) because 3 of Marta's essays have 1000 words. We have 2000x because there are 2000 words, but we don't know how many essays. Lastly, we have 15000 because that is the total number of words. All we have to do is solve for x.

3(1000)+2000x=15000       [multiply]

3000+2000x=15000           [subtract both sides by 3000]

2000x=12000                       [divide both sides by 2000]

x=6

Now, we know there are 6 essays.

Answer:

x = 11

Step-by-step explanation:

x + 5 = 2(x - 3)

x + 5 = 2x - 6

(x - x) + 5 = (2x - x) - 6

5 = x - 6

5 + 6 = x (- 6 + 6)

x = 11
