What is the equation of the circle with center (-3,1) that passes through the point (-5, 3)?
A)
(x - 3)2 + (y + 1)2 = 8
B)
(x + 3)2 + (y – 1)2 = 8
0)
(x + 1)2 – (y - 3)2 = 8
D)
(x + 3)2 - () - 1)2 = 8

Answers

Answer 1

Answer:

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Step-by-step explanation:

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

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

Given

Center = (h,k) = (-3,1)

=> h = -3

=> k = 1

The distance between the center of circle and the point through which the circle passes will be the radius.

The distance formula is given by:

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

Given

[tex](x_1,y_1) = (-3,1)\\(x_2,y_2) = (-5,3)[/tex]

Putting the values in the formula

[tex]r = \sqrt{(-5+3)^2+(3-1)^2}\\r = \sqrt{(-2)^2+(2)^2}\\r = \sqrt{4+4}\\r = \sqrt{8}[/tex]

Putting the values of h,k and r in general form of equation

[tex]\{x-(-3)}^2\} +(y-1)^2 = (\sqrt{8})^2\\(x+3)^2+(y-1)^2 = 8[/tex]

Hence,

Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Compare the slopes m1 & m2 of the lines to determine if the lines are parallel, perpendicular or neither.

Answers

Answer:

In order top to bottom: perpendicular, parallel, neither

Step-by-step explanation:

For lines to be perpendicular, their slopes must be the opposite reciprocals of each other. That means the fraction is flipped and the sign is flipped. For the first one it's 3/4 and -4/3 which is opposite reciprocals.

For lines to be parallel, the slopes are the same. The second one has both slopes = 1/2.

The last one is neither because it's not equal and they're not opposite reciprocals.

I recommend graphing these if you're still having trouble with the concept. You can try desmos.com, that's a good website to use.

c. Segment AC coincides with segment EF.
d. Segment BC coincides with segment ED.​
e. Segment AB coincides with segment ED.

Answers

Answer: B.

C.

E.

Step-by-step explanation:

The true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.

Recall what congruent triangles share in common:

If two triangles are congruent, all three sides of one triangle will be congruent to all corresponding three sides in the other triangle.If two triangles are congruent, all three angles of one triangle will be congruent to all corresponding three angles in the other triangle.

Thus, if triangle ABC is congruent to triangle EDF, then Kiran will know that after the transformation:

<A will coincides with angle E<B will coincides with angle D<C will coincides with F

Segment AC will coincides with EF, AB to ED, as well as BC to DF.

Therefore, the true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.

Gribbles are small, pale white, marine worms that bore through wood. While sometimes considered a pest since they can wreck wooden docks and piers, they are now being studied to determine whether the enzyme they secrete will allow us to turn inedible wood and plant waste into biofuel.1 A sample of 50 gribbles finds an average length of 3.1 mm with a standard deviation of 0.72. Give a best estimate for the length of gribbles, a margin of error for this estimate (with 99% confidence), and a 99% confidence interval. Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. point estimate = Enter your answer; point estimate margin of error = Enter your answer; margin of error The 99% confidence interval is Enter your answer; The 99%confidence interval, value 1 to Enter your answer; The 99%confidence interval, value 2

Answers

Answer:

a) The Margin of Error = 0.26

b) The 99% Confidence Interval = ( 2.84, 3.36)

Step-by-step explanation:

a) Margin of Error

The formula for Margin of Error =

z × Standard deviation/√n

From the above question

The z score for 99% confidence interval = 2.576

Standard deviation = 0.72

n = Random number of samples = 50

Margin of Error =

2.576 × 0.72/√50

= 1.85472 /√(50)

= 0.2622970178

Approximately to 2 decimal places = 0.26

b) 99% Confidence Interval

= Mean ± Margin of Error

Mean = 3.1mm

Confidence Interval = 3.1 ± 0.26

3.1 ± 0.26

= 2.84

3.1 + 0.26

= 3.36

The 99% Confidence Interval = ( 2.84, 3.36)
