Answer:

x+5y+5=0

Step-by-step explanation:

y=5x+6

Therefore the gradient of the line = 5

Now reciprocate the gradient and negate it

i.e -1/5

let (x,y) and (-15,2) be points on the line

y-2/x-(-15)=-⅕

5y-10=-x-15

5y-10+15+x=0

x+5y+5=0

Therefore the equation of the line =

x+5y+5=0

Step-by-step explanation:

needs to be 20 letters long

Step-by-step explanation:

You can find the answer using sine. Basically, since sine=opposite/hypothenuse, you can write an equation to find the length of the hypothenuse. You can find sine on your calculator. We're going to say hypothenuse=h for this equation.

Sine of angle x= y/h

After plugging in the values, you would just solve the equation.

The number of watts which is the power of the turbine for each case is respectively; 600 W; 506.25 W; 300 W

We are given;

Density of air; ρ = 1.2 kg/m³

Area; A = r² with r being the blade length

Formula for power in turbine is;

P = ¹/₂ρAv³

1) v = 10 m/s and r = 1 m.

Thus;

P = ¹/₂ * 1.2 * 1² * 10³

P = 600 W

2) v = 15 m/s and r = 0.5 m.

Thus;

Power = ¹/₂ * 1.2 * 0.5² * 15³

P = 506.25 W

3) v = 20 m/s and r = 0.25 m.

Thus;

Power = ¹/₂ * 1.2 * 0.25² * 20³

P = 300 W

The vertices of the square are the coordinates of the endpoints

The third vertex of the square could be (0,7) or (-5,1)

Two vertices of the square are:

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

Calculate the distance between these vertices using:

[tex]d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}[/tex]

Square both sides

[tex]d^2 = (x_2 - x_1)^2+(y_2 - y_1)^2[/tex]

The above expression represents the area of the square.

So, we have:

[tex](x_2 - x_1)^2+(y_2 - y_1)^2 = 41[/tex]

Next, we test the options with the given vertices (0,-3) and (4,2)

So, we have:

A. (0,7)

[tex](0 - 0)^2+(7 + 3)^2 = 41[/tex]

[tex]100 \ne 41[/tex]

[tex]41 = 41[/tex]

B. (-5,1)

[tex](-5 - 0)^2+(1 + 3)^2 = 41[/tex]

[tex]41 = 41[/tex]

Answer:

n = (s + 360)/ 180

Step-by-step explanation:

180(n - 2)= s ? ummm ill try...

180n - 360 = s

180n = s + 360

n = (s + 360)/ 180

Answer:

n = s/180 +2

Step-by-step explanation:

180 (n-2) = s

Step 1: To find n, we need to get rid of 180 from the left side of the equation. Divide 180 by both sides; then we can cross out 180 with itself on the left, leaving (n-2)

180 (n-2) /180 = s/180

Step 2: Now we got rid of 180 on the left, we must isolate n. To do that, we must bring -2 to the other side of the equation. There, it would become positive, and n gets isolated.

n = s/180 + 2

Although, you may or may not be confused with my answer, and I realized that there's two ways to solve this. Let me show you:

Step 1: 180(n-2) = s

Distribute - multiply 180 with every term in the brackets, which then we would end up with:

180n-360 = s

Step 3: Bring -360 to the right side of the equation, where it would become positive.

180n = s+360

Step 4: To isolate n, divide 180 by both sides of the equation:

180n/180 = s+360/180

Step 4: Now you have:

n = s+360/180.

Though you could leave your answer as the one above, you should simplify it.

Step 5: n = s/180 + 360/180

360/180 = 2, therefore the simplified answer is:

n = s/180 +2

The probability that, out of the next 4 customers, fewer than 2 will share their email address is 17/20.

Given

Casey finds that when asked for their email address, 1/5 of her customers will share their address with her.

To simulate the behavior of the next 4 customers, she writes the numbers 1, 2, 3, 4, and 5 on cards and mixes them up.

She then picks 4 cards, records the results, and puts the cards back.. She repeats this experiment for a total of 20 trials.

The results are shown in the table.

Here, she let 1 represent someone sharing an email address and 2, 3, 4, and 5 represent someone not sharing an email address.

4121 1223 4233 3344 2434 4241 5415 3421 5214 2234 4211 1432 5532 4114 4325 4454 4523 4432 3423 1352

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

There are 17 are the favorable no. of outcomes and 20 are the total outcomes.

The probability that, out of the next 4 customers, fewer than 2 will share their email address is;

[tex]\rm Probability = \dfrac{Favorable \ Outcomes}{Total \ number \ of \ outcome}\\\\Proabaility=\dfrac{17}{20}[/tex]

They watch anime in their room for 5 hours then come back later. Frank is a dad. The "people" is his daughter. IM KIDDING, but more info please i dont really understand

Step-by-step explanation:

because is true (ITS NOT)

In addition to the fact that she has never kept a diary before, Anne Frank finds it strange that someone like her would do so. She also believes that neither she nor anybody else would find interest in a diary kept by a thirteen-year-old schoolgirl.

The residents are given five minutes to gather their belongings when the military break down the annex door. Nothing else may be taken by them. The scene comes to a close as Anne's voice commands Miep to keep her diary secure.

Frank discussed how people saw her in her final journal post, calling herself "a tangle of paradoxes." "As I've told you many times, I'm torn in two," she wrote. One half of myself is full of excitement, exuberance, flippancy, and, most importantly, the capacity to see the lighter side of things.

Thus, Anne Frank finds it strange that someone like her would do so.

Step-by-step explanation:

Answer:

Length of the garden: 95 m

Width of the window: 86 cm

Step-by-step explanation:

Part A:

We can use the equation for area to find the length of the garden.

[tex]Area = Width * Length[/tex]

If we simply divide both sides of the equation by width, we will be solving for lenght:

[tex]\frac{Area}{Width} = Length[/tex]

Now, plug in the known values for the area and width of the garden:

[tex]\frac{6460}{68}=Length[/tex]

[tex]95=Length[/tex]

Part B:

This time, we'll have to use the equation for perimeter:

[tex]Perimeter = [2(Width)]+[2(Length)][/tex]

Because we want to know the width, and already know the perimeter and length we can once again use algebra to solve for the width:

[tex]Perimeter-[2(Length)] = 2(Width)\\\frac{Perimeter-[2(Length)]}{2} =Width[/tex]

Now, simply plug in the values for the perimeter and the length and solve:

[tex]\frac{370-[2(99)]}{2} =Width\\\\\frac{370-198}{2} =Width\\\\\frac{172}{2}=Width\\\\86=Width[/tex]

Therefore, the width of the window is 86 cm.

Answer:

Step-by-step explanation:

(a -b)² = a² - 2ab + b²

Here, a = 6x & b = 5

Area of a square = side * side

                            = (6x - 5)*(6x - 5)

                            = (6x - 5)²

                            = (6x)² - 2*6x*5 + 5²

                             = 36x² - 60x + 25

Without replacement, there are 4 out of 20, and then 3 out of 19 cards with a 1, hence:

[tex]p = \frac{4}{20} \times \frac{3}{19} = 0.0316[/tex]

0.0316 = 3.16% probability that both cards selected have a 1 without replacement.

With replacement, in each trial, 4 out of 20, hence:

[tex]p = \frac{4}{20} \times \frac{4}{20} = 0.04[/tex]

0.04 = 4% probability that both cards selected have a 1 with replacement.
