Find the reference angle for a rotation of 208º.
blsea [12.9K]

Answer:

I'm not sure the answer but I can tell you how to solve.

Step-by-step explanation:

Identify your initial angle. For this example, we’ll use 440° 2. The angle is larger than a full angle of 360°, so you need to subtract the total angle until it’s small. 440° - 360° = 80° 3.

What are the coordinates of the center of the circle (x-1)²+(y-2)²=2² and y=2x+2?
defon

Answer:

Compare the given equation of the circle (x - 1)² + (y -2)² = 2²

with standard form of circle: (x - h)² + (y - k)² = r²

Here, (h, k) is the center of the circle

and r is the radius of the circle.

Thus, The center of the circle is: (1, 2)

Also, for finding the point of intersections of (x - 1)² + (y -2)² = 2² and y = 2x + 2,

Substitute the value of y from equation of line in the equation of circle.

(x - 1)² + (2x + 2 - 2)² = 2²

⇒ (x - 1)² + (2x)² = 2²

⇒ x² + 1 - 2x + 4x² = 4

⇒ 5x² - 2x - 3 = 0

Applying Middle term splitting method

5x² - 5x + 3x - 3 = 0

⇒ 5x(x - 1) + 3(x - 1) = 0

⇒ (5x + 3)(x - 1) = 0

⇒ x = \frac{-3}{5} and x = 1

Thus, we get coordinates: (\frac{-3}{5} ,\frac{4}{5} ) and (1, 4)

Can you help please?? ​
romanna [79]

Step-by-step explanation:

this relation is not a function cuz each x pair (domian) has only one image in y pair (codomain) so we will have all the ×-axis pairs meeting with y-axis in only one point as they have one image as this is the rule of having a function so what in front of us the positive part of x-axis has two images in y-axis

u can knew it by another way draw a vertical line and if it meets in two point or more than one then the relation is not a function s o if we draw a vertical line in the right part of the graph it will meats in two points then not a function

the domain is all the pairs of this relation taken in x-axis which are [0,infinity[ and range is the y-axis images if the fomain in x-axis which are ]-infinity, infinity[

A local newspaper was wondering if its average reader lived more than 25 miles from its headquarters. The newspaper surveyed its
Alex777 [14]

Answer:

We fail to reject H₀.

At the 5% significance level, the data do not provide sufficient evidence to conclude that the average distance a reader lives from the newspaper's headquarters is greater than 25 miles.

Step-by-step explanation:

The hypothesis for the statistical test is defined as follows:

<em>H</em>₀ : <em>μ </em>=25 vs. <em>Hₐ</em> : <em>μ </em>> 25

The test statistic value is, <em>z</em>₀ = 0.22.

The <em>p</em>-value of the test is, <em>p</em>-value = 0.41.

The significance level is, <em>α</em> = 0.05.

The <em>p</em>-value is well defined as per the probability, [under the null hypothesis (H₀)], of attaining a result equivalent to or more extreme than what was truly observed.

A small <em>p</em>-value (typically ≤ 0.05) specifies strong evidence against the null hypothesis (H₀), so you discard H₀.

A large p-value (> 0.05) specifies fragile proof against the H₀, so you fail to discard H₀.

Here, <em>p</em>-value = 0.41 > <em>α</em> = 0.05.

The null hypothesis was failed to be rejected at 5% level of significance.

Conclusion:

There is not enough evidence to support the claim that the average distance a reader lives from the newspaper's headquarters is greater than 25 miles.
