Enter the coordinates of the point

agasfer [191]

Answer: $(\frac{\sqrt{3} }{2} ,-\frac{1}{2} )$

Step-by-step explanation:

this forms a 30 degree reference angle

and this is in the 4th quadrant

When the angle is 30 degrees, the coordinates are:

$(\frac{\sqrt{3} }{2} ,-\frac{1}{2} )$

Tia types 66 words in 3 minutes. She wants to know how many words she can type in 5 and 10 minutes if she keeps the same rate.

olchik [2.2K]

Answer:

110 words in 5 min, 220 words in 10 min

Step-by-step explanation:

y = mx (there is no intercept because you can't type anything in 0 minutes)

66 = 3m

m = 22

y = 22x

5 minutes:

y = 22(5) = 110 words

10 minutes:

y = 22(10) = 220 words

4) (Assume AR is tangent) Given: AR 12 SR - 7.7 Find: cs (Round to nearest tenth.)

andreev551 [17]

The length of CS is 11.0

Explanation:

Given that the length of the tangent AR is 12

The length of SR is 7.7

To find: The length of CS

The tangent secant theorem states that "if a tangent and a secant are drawn from an external point to a circle, then the square of the measure of the tangent is equal to the product of the measures of the secant’s external part and the entire secant."

Applying the tangent secant theorem, we have,

$AR^2=SR\times RC$

Rewriting the above equation, we get,

$AR^2=SR(SR+SC)$

Substituting the values, we get,

$12^2=7.7(7.7+CS)$

Simplifying, we have,

$144=59.29+7.7CS$

Subtracting both sides by 59.29, we get,

$84.71=7.7CS$

Dividing both sides by 7.7, we have,

$11.0013=CS$

Rounding off to the nearest tenth, we get,

$11.0=CS$

Thus, the length of CS is 11.0

Explain what each of the following sample correlation coefficients tells you about the relationship between the x and y values i

Alchen [17]

Answer: The description are as follows:

Step-by-step explanation:

Correlation coefficients is a statistical measure that measures the relationship between the two variables.

(a) r = 1, it means that there is a Perfect positive relationship between the two variables. If there is positive increase in one variable then other variable also increases with a fixed proportion.

(b) r = -1, it means that there is a perfect negative relationship between the two variables. If there is positive increase in one variable then other variable decreases with a fixed proportion.

(c) r = 0, this is a situation which shows that there is no relationship between the two variables.

(d) r = 0.86, this is a situation which shows that there is a fairly strong positive relationship between the two variables.

(e) r = 0.06, it is nearly zero which represents that either there is a very minor positive relationship between the two variables or there is no relationship between them.

(f) r = -0.89, this is a situation which shows that there is a fairly strong negative relationship between the two variables.
