Which equation has the following: Center (0, -3) and radius: square root of 11.


A. x2 + (y - 3)2 = 11


B. x2 + (y - 3)2 = 121


C. x2 + (y + 3)2 = 11


D. x2 + (y + 3)2 = 121


Answers

D. I believe bc part of the equation is (y-y one) and y one is -3 and two negatives make a positive. And 11 squared it 121

Answer:

[tex]\text{C. }x^2+(y+3)^2=11[/tex]

Step-by-step explanation:

The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:

[tex](x-h)^2+(y-k)^2=r^2[/tex].

What we're given:

radius of [tex]\sqrt{11}[/tex] center at [tex](0,-3)[/tex]

Substituting given values, we get:

[tex](x-0)^2+(y-(-3))^2=\sqrt{11}^2,\\\boxed{\text{C. }x^2+(y+3)^2=11}[/tex]

What is the sun of the interior angles in the figure shown?
- 210

Answers

Answer:

720°

Step-by-step explanation:

(180° x 6) - 360° = 720°

checking:

(right side) 2 angles 90° = 180°

(left side) 0ne pair of supplementary angles = 180°

(center) One angle  180° + ?°

             One angle  180° - ?°

             Equals 2 angles  180°

             Total = 720°

Answers

Answer:

The answer is  

a.

$75,000

Step-by-step explanation:

The face value of the 10-year term insurance policy on a 24-year-old male is $359.25 is given as follows: $75,000.

What is the face value of the insurance policy?

The face value of the insurance policy is given by the equation presented as follows:

Face value = 1,000 x (Annual premium / Amount paid per $1,000 coverage )

The parameters for this problem are given as:

Annual premium = $359.25, as given in the problem.

Also, Amount paid per $1,000 coverage for 24 year old male for 10 year policy = 4.79,

Hence the face value is calculated as:

Face value = 1000 x 359.25/4.79

Face value = $75,000.

Area of figure 2 = 150 square cmWX = 25/6 cm (exact)WX = 4.167 (approximate)

It's not clear which version of WX your teacher wants, so I provided both of them.

============================================================

Explanation:

Focus on the perimeters. The jump from 36 to 30 means the linear scale factor is 30/36 = 5/6

This means,

WX/YZ = 5/6

WX/5 = 5/6

6WX = 5*5

6WX = 25

WX = 25/6 which is exact

WX = 4.167 approximately

---------------

The linear scale factor is 5/6, so the area scale factor is (5/6)^2 = 25/36.

The area of figure 1 is 216 cm^2, making the area of figure 2 to be 216*(25/36) = 150 cm^2

Line segment TU has endpoints (-7,10) and (-6,-5). What is the length of TU to the NEAREST TENTH?

Answers

Answer: 15 units

Step-by-step explanation:

Given

The endpoints of the line segment are [tex](-7,10)\ \text{and}\ (-6,-5)[/tex]

The length of the line segment is given by the distance formula i.e.  

[tex]d=\sqrt{\left( x_2-x_1\right)^2+\left( y_2-y_1\right)^2}[/tex]

Insert the values,

[tex]\Rightarrow d=\sqrt{\left( -6+7\right)^2+\left( -5-10\right)^2}\\\Rightarrow d=\sqrt{1^2+\left( -15\right)^2}\\\Rightarrow d=\sqrt{1+225}\\\Rightarrow d=15.0\ \text{units}[/tex]

Therefore, the length of line segment TU is 15 units

[tex]\sqrt{40}[/tex] or 6.32

Step-by-step explanation:

We can find the distance between two points by using this formula

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where the x and y values are derived from the given points

The points given are ( -2 , 5 ) and ( 4 , 3 )

So we plug in the x and y values of those coordinates into the distance formula

[tex]\sqrt{(4-(-2)^2+(3-5)^2} \\4-(-2)=6\\3-5=-2\\d=\sqrt{6^2+-2^2} \\6^2=36\\-2^2=4\\36+4=40\\d=\sqrt{40}[/tex]

60% white, 40% black

The first draw you have a 60% chance drawing a white marble, the second time you have a 55% chance since you already drew one in the first round. so i think it is 60.5%% chance drawing white on both rounds since I add 60+55=121. 121/200=60.5%

Answers

Answer:

87.2º

Step-by-step explanation:

Complimentary angles total 90º

c + 2.8 = 90

c = 90 - 2.8

c = 87.2º

Answer:

87.2°

Step-by-step explanation:

When angles are complementary, it means that they both add up to 90°.

In this case, one of the angles measures 2.8°.

So, to find the other one, we subtract 2.8 from 90.

90 - 2.8 = 87.2

The measure of the complementary angle is 87.2°

There he gets terribly bored and looking through his grandfather's closet, he came across a bag full of dice. Having no one to play dice with, but it seemed to him that some of the dice were heavier than the others, Costica chose a dice and started to test it by throwing it with him and noting how many times each face fell. He then tries to figure out whether the dice are rolled or not, considering that the difference between the maximum number of appearances of one face and the minimum number of occurrences (of any other face) should not exceed 10% of the total number of throws.RequirementGiven a number N of dice rolls and then N natural numbers in the range [1: 6] representing the numbers obtained on the rolls, determine whether the dice is tricked according to the above condition.Input dataFrom the input (stdin stream) on the first line reads the natural number N, representing the number of rolls. On the following N lines there is a natural number in the range [1: 6] representing the numbers obtained on throws.Output dataAt the output (stdout stream) a single number will be displayed, 0 or 1, 0 if the dice are normal, and 1 if it is cheated.ATTENTION to the requirement of the problem: the results must be displayed EXACTLY in the way indicated!
