Which Of The Following Is NOT A Variation Of A Pythagorean Identity?

Answers

Answer 1

The expression that is not a variation of the Pythagorean identity is the third option.

What is the Pythagorean identity?

The Pythagorean identity can be written as:

[tex]sin^2(x) + cos^2(x) = 1[/tex]

For example, if we subtract cos^2(x) on both sides we get the second option:

[tex]sin^2(x) = 1 - cos^2(x)[/tex]

Which is a variation.

Now, let's divide both sides by cos^2(x).

[tex]sin^2(x)/cos^2(x) + cos^2(x)/cos^2(x) = 1/cos^2(x)\\\\tan^2(x) + 1 = sec^2(x)\\\\tan^2(x) - sec^2(x) = -1[/tex]

Notice that the third expression in the options looks like this one, but the one on the right side is positive. The above expression is in did a variation of the Pythagorean identity, then the one written in the options (with the 1 instead of the -1) is incorrect, meaning that it is not a variation of the Pythagorean identity.

Concluding, the correct option is the third one.

24) area= 16 pi inches squared

Find the circumference

It doesn't give any pictures​

Answers

Answer:

8π in

Step-by-step explanation:

The Area of a Circle is πr². In this case, we're given the area as 16π, so the radius is 4 because the square root of 16 is 4.

The Circumference of a Circle is 2πr. Since the radius is 4:

[tex]2*4 * \pi[/tex] [tex]8\pi[/tex]

Therefore, the circumference is 8π inches.

What is the equation of the vertical asymptote for the graph below? y=1/x−2

very cheap answer

vertical asymptoes occur when the denominator turns to zero, in this case we know the denominator is x - 2, so let's zero it out, by x - 2 = 0, thus x = 2, that's the equation of the vertical asymptote, or namely, the vertical line of x = 2 marks the line where the graph glides over but never touches it.

Answers

By taking the quotient between the number of yellow gumballs and the total number of gumballs, we will see that the probability is:

p = 0.17, so the correct option is C.

How to get the probability?

If we assume that all the gumballs have the same probability of being selected by the machine, then the probability of getting a yellow gumball is given by the quotient between the number of yellow gumballs and the total number of gumballs.

There are 74 yellow gumballs.There are 86 + 74 + 103+ 94 +89 = 446 gumballs in the machine.

So the probability of getting a yellow one is:

p = 74/446 = 0.17

The correct option is C.

I need help solving this problem I'm stuck on.

Answers

Answer:

S = -90t + 550

Step-by-step explanation:

First we must note a few key things the question tells us:

1. The tickets sell at a constant rate, thus implying a linear relationship.

2. Tickets start selling at 10

3. The independent variable (t) is in hours after 10

4. The number of tickets (S) is declining, thus we should expect a negative gradient.

5. The number of tickets is our dependent variable since it is reliant on time.

y = mx+c is our general linear expression which we will call "Eq 0"

Lets substitute our knowns into this to find m and c. We know that "t" is independent and that "S" is dependent on "t" therefore, we know that our x-axis will be representing values for "t" and that our y-axis will represent values for "S"

We must use simultaneous equations to find m and c

Eq 1: 550 = m(0) + c -> 550 = c

Eq 2: 280 = m(3) + c -> 280 = 3m + c

From Eq 1. we already know that our y intercept is at 550.

To find our gradient, we must substitute our known (550 being the y-intercept) into the next equation.

Thus,

280 = 3m + 550

To isolate our variable (m) we subtract both sides by 550

280 - 550 = 3m + 550 - 550

-270 = 3m

To finally find m, we divide both sides by 3

-270/3 = 3m/3

-90 = m

Now we substitue both our knows into Eq 0, note that our gradient (m) is negative as expected.

y = -90x + 550

Or, in terms of S and t

S = -90t + 550

Lightning flashes every 15 seconds one rainy night. How many times would it flash in 3 minutes? *​

Answers

Well if one minute is 60 seconds then 60x3 is 180. Then I would divide 180 by 15 and that would equal 12. It would flash 12 times in 3 minutes.

12 times in 3 minutes

Lightning flashes every 15 seconds and there’s four 15 seconds in one minute. So in a minute lightning strikes 4 times then you multiply the 4 times 3 minutes and you get 12.

Solve the following system of equations graphically on the set of axes below.
y = 2x – 1
x + 3y = 18

Answers

Answer:

  (x, y) = (3, 5)

Step-by-step explanation:

To solve these equations graphically, you plot each one, then identify the coordinates of the point of intersection.

The first equation can be graphed using the y-intercept of -1 and the slope of 2.

The second equation has a y-intercept of 18/3 = 6, and a slope of -1/3. The x-intercept of 18 is off the chart, so the slope and intercept are a good way to plot this line, too.

__

The slope is the "rise" divided by the "run". A slope of 2 means the line goes up 2 units for each unit to the right. A slope of -1/3 means the line goes down 1 unit for each 3 units to the right.

The solution is (x, y) = (3, 5).
