X = -3
y = 3*sqrt(3)

r = sqrt(x^2 + y^2)
r = sqrt((-3)^2 + (3*sqrt(3))^2)
<span>r = sqrt(9+27)
</span><span>r = sqrt(36)
</span>r = 6

theta = arctan(y/x)
<span>theta = arctan(3sqrt(3)/(-3))
</span>theta = arctan(-sqrt(3))
theta = -60 degrees which is coterminal to 300 degrees

So the polar form is (r,theta) = (6, 300)

Given sin(theta)= 7/11 and sec(theta)&lt;0<br> Find cos(theta) and tan(theta)
allsm [11]
When given a trigonometric ratio, and asked to find another ratio, we draw a right triangle as shown in the picture.

From the pythagorean theorem we find the length of AB:

 |AB|= \sqrt{ AC^{2}- BC^{2} }=  \sqrt{ 11^{2}- 7^{2} }= \sqrt{121-49} = \sqrt{72} =  \sqrt{2*36} = 6\sqrt{2}

the numerical value of

cos∅=adjacent side/hypotenuse=\frac{ 6 \sqrt{2} }{11}

since sec∅=1/cos∅, and sec∅ is negative, then cos∅ is also negative.


Answer: 

cos∅=-\frac{ 6 \sqrt{2} }{11}

Make use of the given interpretation for the median to assign probabilities to the simple events and find P(A), P(B), and P(C).
scoundrel [369]

Answer: Hello your question is incomplete below is the missing part of the question

The Bureau of the Census reports that the median family income for all families in the United States during the year 2003 was $43,318. That is, half of all American families had incomes  exceeding this amount, and half had incomes equal to or below this amount. Suppose that four  families are surveyed and that each one reveals whether its income exceeded $43,318 in 2003.

answer :

P(A) = 11 / 16

P(B)  = 3/8

and P(C) = 1/4

Step-by-step explanation:

Making use of the given interpretation for the median we can assign probabilities to simple events as

P(A) = | A | / | sample space |

where | A | = 11

sample space = 16

P(A) = 11 / 16

∴ P(B) = 6/16 = 3/8

and P(C) = 4/16 = 1/4
