a.0^2 +1^2=1
b.0^2 +(-1)^2=1
c. 1^2+0^2=1
d.(-1)^2+0^2=1

Answers

Answer 1

Answer: For This Specific Question it is B, But there is a question very similar that doesn't have the pi's in the equation and the answer to that one is A.

Step-by-step explanation: Very sorry if this is confusing :)

Answer 2

Pythagorean identities are three basic identities for trigonometric ratios. The equation that is of the form [tex]\sin^2(\pi) + \cos^2(\pi) =1[/tex] is given by: Option B: [tex]0^2 + (-1)^2 = 1[/tex]

Equations which shows that the Pythagorean identities are true will be verifying them for some specific angles. For that we need to know about Pythagorean identities.

What are Pythagorean identities?

[tex]sin^2(\theta) + cos^2(\theta) = 1\\\\1 + tan^2(\theta) = sec^2(\theta)\\\\1 + cot^2(\theta) = csc^2(\theta)[/tex]

Using the first Pythagorean Identity to get one of its special case

For angle being [tex]\pi[/tex] radians(or equal to 180 degrees), we have:

[tex]sin(\pi) = 0\\cos(\pi) = -1[/tex]

Thus, for the first Pythagorean identity at angle [tex]\pi[/tex] radians, we get:

[tex]sin^2(\pi) + cos^2(\pi) = 1\\\\0^2 + (-1)^2 = 1[/tex]

Thus, the equation that is of the form [tex]\sin^2(\pi) + \cos^2(\pi) =1[/tex] is given by: Option B: [tex]0^2 + (-1)^2 = 1[/tex]

If the coefficient of determination is 0.394, what percentage of the data about the regression line is unexplained

Answers

Answer:

The percentage [regression line is unexplained]  = 60.6%

Step-by-step explanation:

Given:

Coefficient of determination = 0.394

Find:

The percentage [regression line is unexplained]

Computation:

Coefficient of determination = 0.394

Coefficient of determination = 39.4%

The percentage [regression line is unexplained]  = 100% - Coefficient of determination

The percentage [regression line is unexplained]  = 100% - 39.4%

The percentage [regression line is unexplained]  = 60.6%

Answer:

41º

Step-by-step explanation:

Because of parallel lines, (2x-5)º=180º-113º, so (2x-5)º=67º.

(2x-5)º=67º2x-5=67º2xº=72ºx=36º

The angle that says (2x)º will be (2[36])º=72º.

So the other angle will be 180-67-72=41º as the sum of a triangle's interior angles is 180º.

Answer:

41°

Step-by-step explanation:

The angle below (2x-5) is also 113° (which i hope you know why)

Then to find (2x-5)° you would subtract 180 - 113 to get the angle because both those angles would add up to 180° because it is a straight angle which gives you 67°

Then you need to find x by solving the equation 2x - 5 = 67 which would give you x = 36, so you would multiply that by 2 for the angle on the side which would be 72°

Then bc the angles on the inside of the triangle all add up to 180° as well, you would add 72 + 67 = 139, then do 180 - 139 giving you d° as 41°

Find the slope, if it exists, of the line containing the pair of points.
(8,-6) and (3,9)

Answers

Answer:

The slope is -3

Step-by-step explanation:

the equation for finding the slope between two different points is:

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

Or in other words the change in y over the change in x.

M= (9+6)/(3-8) = 15/-5 = -3.

(sidenote: I added 9 and 6 for the change in y because you cannot subtract a negative number. Instead you have to add it.)

Slope = change in y / change in x

Both x values are the same, they are both 2’s. 2-2 = 0

Because the change in x is 0 the slope is undefined.

An undefined slope means the line is a vertical line ( straight up and down with no angle)

Answer:

$47.74

Step-by-step explanation:

Sales tax rate: 5%;

Price without tax: $3.25 dollars;

Amount of sales tax ≈ $0.16 dollars;

Price with sales tax ≈ $3.41 dollars;

5% × 3.25 =

5/100 × 3.25 =

0.05 × 3.25 =

0.1625 ≈

0.16;

y = -4x - 7

Step-by-step explanation:

we use the slope intercept formula given by; y = mx + b

b = y intercept, which is when x = 0

m = slope

so they tell us the slope.. we just need to find b - the y intercept.

y = mx + b

plug in your coordinates (-2,1)

1 = -4(-2) + b

1 = 8 + b
