Find the radius of the given circle with the center at (-2,1) and a point on the circle at (0,3).
Answers
Answer:
The radius of the given circle ( r ) = 2√2
Step-by-step explanation:
Step(i):-
Given that the center of the circle C = ( -2,1)
Given a point on the circle P = (0,3)
The distance between the center and point is called the radius of the circle
CP = radius of the circle
Step(ii):-
[tex]CP = \sqrt{x_{2} - x_{1})^{2} +(y_{2} -y_{1} )^{2} }[/tex]
[tex]CP = \sqrt{(0 - (-2))^{2} +(3-1)^{2} } \\CP = \sqrt{4+4}[/tex]
CP = √8 = [tex]\sqrt{4 X 2} = 2\sqrt{2}[/tex]
Final answer:-
The radius of the given circle ( r ) = 2√2

11. The distance between two houses in a neighborhood is 12 meters. There are approximately 4 meters in 13 feet. Which measurement, in feet, is closest to the distance between the two houses?
Answers
Answer:
The closest distance between the houses in feet is 39 feet
Step-by-step explanation:
Distance between the houses in metres is 12 metres.
Essentially, the problem is asking us to convert this distance to feet using the scale ratio that we are given.
The scale ratio is
4 meters = 13 feet.
1 meter = x feet
by cross multiplying, we have that x = 13/4 feet
We now know how long 1 meter is in feet using the scale we were given
We can now convert the 12 meters to feet.
1 meter = 13/4 feet
12 meters = x feet
[tex]x = 12 \times 13/4=39 feet[/tex]
Therefore, the closest distance between the houses in feet is 39 feet
Identify the number of solutions for the equation below:
Answers
Answer:
one solutionStep-by-step explanation:
Given the expression
3 -x = 2+x
We re to find the number of solutions we will have:
Subtract 2 from both sides
3-x-3 = 2+x -3
-x = x -1
subtract x from both sides
-x - x = x - 1 - x
-2x =-1
Divide both sides by -2
-2x/-2 = -1/-2
x = 1/2
Since the value of x is just 1, hence the equation has just one solution.

OY=650x3
I need bad help.
Answers
Answer:
ANSWER
y = 3x + 6.50
EXPLANATION
The $3 for each downloaded movie is the unit rate of change.
This is represent the slope of the linear function that models this situation.
The monthly fee of monthly fee of $6.50 the constant rate.
It represents the y-intercept of the function.
The linear function is given by
y = mx + by=mx+b
The correct choice is y = 3x + 6.50
Answer:
A. Y= 3x6.50
Step-by-step explanation: This is the correct answer, because you can use the process of elimination on answers B and C due to how they are set up. And D is incorrect, because there is no decimal in 650 which is not the correct number in the problem. Therefore, A. Y= $3 for each downloaded movie multiplied by the monthly fee of $6.50 is the correct answer. Hope this helps ^-^.

What is Pythagoras theorem?The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Given
Length of the ladder = 12 ft
Distance from the bottom = 1/4 of length of the ladder
= [tex]\frac{1}{4}[/tex] × [tex]12[/tex]

Answers
Answer: 4 hours
Step-by-step explanation:
$77.00 divided by $7.00 = 11 hours
11 hours- 3 hours (Friday)- 4 hours (Saturday)= 4 hours on Sunday
A total of 7 hours worked on Fri. and Sat.
Answer:
Caitlin worked 4 hours on Sunday.
Step-by-step explanation:
The answer is 4 hours because 7.00 multiplied by 7 (Because 3 + 4 = 7) is 49.00 and 77.00 minus 49.00 = 28.00 and since 1 hour = 7.00 and 7.00 multiplied by 4 is 28.00 then the answer must be 4 hours.

Step-by-step explanation:
One sit of the 48 degrees is 48 degrees, so that opposite will be the same. Add them up, get 96. There is a full 360 degrees circle, so get 360 and subtract 96 from it, to get 264 degrees. That is the top and bottom angle of the right side, so just divide it in two
Answer:
I think x= 84
if the lines are parallel then the angle should be the same. Because one angle =48° the other side is likely to equal the same. Add 48+48, subtract 180 from your answer and that's how you get 84°. hope this helps

The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.
B. y = 50x + 300
Step-by-step explanation:
A.
The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.
For all the years after is when the line graph goes up which means they are adding to their total number.
B. For the city of Revere, they started out with 300 and are adding 50 Chromebooks every year.
Y represents the total and x is each counting year.
So the equation of the line is represented by y = mx + b
b is any constant which in this case is any initial amount (300)
and m is the rate/change which is the number represented by the value that will go up ever year of x (50)
So plug it all in equals:
y = 50x + 300

In a right triangle, the length of one leg is 20 units. The length of the other leg is 12 units.
What are Pythagorean triplets?In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.
Here,
Apply Pythagoras' theorem,
(hypotenuse)² = sum of the square of the legs,
(hypotenuse)² = 20² + 12²
(hypotenuse)² = 544
hypotenuse = √544
Thus, the required measure of the hypotenuse length is √544. Option D is correct.
