The center of the circle is at (2,5).A point on the circumference is at (10,3).First, we need to find the radius, which is the distance between the given points.
[tex]d=\sqrt{(3-5)^{2} +(10-2)^{2} } =\sqrt{4+64}=\sqrt{68}[/tex]
Therefore, the radius of the circle is
[tex]r \approx 8.25[/tex]
The explicit form of the equation of the circle would be

Tristen is building 3 trophies using Legos. He needs 324 total Legos. Tristen uses 220 Legos for the largest trophy and 135 Legos for the smallest trophy. How many Legos will he use to build the final trophy
Answer: 166
Step-by-step explanation:
Number of trophies = 3
Total Legos required for all trophies = 324
Number of Legos for largest trophy(A) = 220
Number of Legos for smallest trophy(B) = 135
Number of Legos required for final trophy(C)
=?
Total Legos = [Number of Legos for largest trophy(A) + Number of Legos for smallest trophy(B) + Number of Legos required for final trophy(C)]
324 = 220 +135 + C
324 = 355 + C
324 - 355 = C
-31 = C
135 + 31 = 166
Answer:
614 legos

A sandwich shop is ordering apples and grapes to make chicken salad.Apples cost $2.19 per pound and grapes cost $2.60 per pound. If they ordered a total of 20 pounds of apples and grapes and pair $35.80. How many pounds of grapes did they order?
Answer:
Grapes=19.51
Step-by-step explanation:
Apples=$2.19 per pound
Grapes=$2.60 per pound
Apples+Grapes=20 pounds
A+G=20
A=20-G
Equation is
PaA+PgG=35.80
2.19A+2.60G=35.80
2.19(20-G)+2.60G=35.80
43.8-2.19G+2.60G=35.80
43.8-0.41G=35.80
-0.41G=35.80-43.8
-0.41G=-8
Divide both sides by 0.41
G=19.51 pounds
Recall
A=20-G
A=20-19.51
A=0.49 pounds
They ordered 19.51 pounds of grapes.
let us say they ordered 'x' pound of grapes.
so, the quantity of apples ordered = (20-x) pound
it is given that
cost of the apple= $2.19 per pound
cost of the grapes= $2.60 per pound
according to the given scenario,
total cost = $35.80
What will be the total cost?the total cost will be the sum of the cost of apples as well as grapes.
2.60x + 2.19(20-x) =35.80
-0.41x = 8
x = -19.51 pounds
therefore, they ordered 19.51 pounds of grapes.

Graph y=2x on the coordinate graph above. Compare the two lines. Does either line represent a proportional relationship? Explain.
Answer:
IDK the other line.
Step-by-step explanation:
y=2x is a proportional relationship because it has a 1:2 ratio, where as the x increases by one point, the y value will constantly increase by 2 points.
Which equation is equivalent to the following?
2x^2 - 12x + 2y^2 + 20y - 28 = 0
1) 2(x-3)^2 +2( y+5)^2=44
2) 2(x-3)^2+2(y+5)^2=60
3) 2(x-3)^2+2(y+5)^2=62
4) 2(x-3)^2+2(y+5)^2=96
Answer:
Therefore, the equivalent expression is: 2*(x - 3)² + 2*(y + 5)² = 96. Number 4)
Step-by-step explanation:
In order to find the equivalent expression, lets first factor the common term, which is "2":
2*(x² - 6*x + y² + 10 *y - 14) = 0
If we look closely to the terms that have "x" and "y", they both have a square structure, therefore we can complete the squares by manipulating the indepent term. Let's first check the term with "x" and "y":
x² - 6*x + c² = x² - 2*3*x + c² = (x - c)²
y² + 10*y + d² = y² + 2*5*y + d²= (y + d)²
In order to complete the squares, c must be equal to 3 and d must be equal to 5. We can arrange that, by summing and subtracting these numbers squared, we have:
2*(x² - 6*x + 3² + y² + 10 *y +5² - 14 - 3² - 5²) = 0
2*(x² - 6*x + 3²) + 2*(y² + 10*y + 5²) -28 - 18 - 50 = 0
2*(x - 3)² + 2*(y + 5)² = 96
Therefore, the equivalent expression is: 2*(x - 3)² + 2*(y + 5)² = 96
Answer:
2*(x - 3)² + 2*(y + 5)² = 96.

An experiment consists of randomly drawing a cube from a bag containing three red and two blue cubes.
2. List the probability of each outcome in the sample space.
3.
Is the probability of selecting a red cube equal to the probability of selecting a blue cube? Explain.
Answer: 2)The probability of drawing a red cube is 3/5 and the probability of drawing a blue cube us 2/5.
3) No the probability of selecting a red cube is not equal to probability of selecting a blue cube because the outcomes 3/5 and 2/5 are not equal.
Step-by-step explanation:
The probability of each outcome in the sample space is:
Probability of drawing a red cube = 3/5
Probability of drawing a blue cube = 2/5
No, the probability of selecting a red cube is not equal to the probability of selecting a blue cube.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required event / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The sample space of this experiment consists of the possible outcomes of randomly drawing a cube from the bag.
There are two possible outcomes: either a red cube is drawn or a blue cube is drawn.
So, the probability of each outcome in the sample space is:
Probability of drawing a red cube = 3/5
Probability of drawing a blue cube = 2/5
No, the probability of selecting a red cube is not equal to the probability of selecting a blue cube.
This is because there are more red cubes in the bag than blue cubes, so the probability of drawing a red cube is higher than the probability of drawing a blue cube.
Specifically, the probability of drawing a red cube is 3/5, which is greater than the probability of drawing a blue cube, which is 2/5.
Thus,
The probability of each outcome in the sample space is:
Probability of drawing a red cube = 3/5
Probability of drawing a blue cube = 2/5
No, the probability of selecting a red cube is not equal to the probability of selecting a blue cube.

A number is chosen at random from 1 to 10. Find the probability of selecting a 6 or greater.
Answer:
1/2
Step-by-step explanation:
p(event) = (number of desired outcomes)/(total number of outcomes)
How many different outcomes are there? You can choose 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10, so the total number of possible outcomes is 10.
How many outcomes are desired. The desired outcomes are any outcomes with a number 6 or higher. Which numbers are 6 or higher? 6, 7, 8, 9, 10. There are 5 outcomes that are 6 or higher, so there are 5 desired outcomes.
p(event) = (number of desired outcomes)/(total number of outcomes)
p(event) = 5/10 = 1/2

Two variables are always sometimes I never) correlated.
4. In the U.S., from 2004 - 2015, the correlation coefficient for the relationship
between the size of a cell phone data plan, x, and the number of text
messages sent, y, is r = +0.97. Describe the relationship between the data
plan size and the number of text messages sent in the U.S.
Answer:
There is strong positive correlation between the size of a cell phone data plan and the number of text messages sent in the U.S.
Step-by-step explanation:
The correlation coefficient is a statistical degree that computes the strength of the linear relationship amid the relative movements of the two variables (i.e. dependent and independent). The correlation coefficient value ranges from -1 to +1.
Positive correlation is an association amid two variables in which both variables change in the same direction.
A positive correlation occurs when one variable declines as the other variable declines, or one variable escalates while the other escalates.
The closer the the correlation coefficient value gets to +1 or -1, the stronger relation becomes.
The correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y, is:
r = +0.97
The correlation coefficient is closer to +1.
Thus, there is strong positive correlation between the size of a cell phone data plan and the number of text messages sent in the U.S.

Find the length of the radius.
Give your answer rounded to 1 DP.
PLEASE HELP
i will give you brainiest if you can can answer in 3 minutes
Answer:
R = 2.6 mm
Step-by-step explanation:
D = C ÷ π
D = 15.9 ÷ 3.14
D = 5.06
D = 5.1 mm
R = D ÷ 2
R = 5.1 ÷ 2
R = 2.55
R = 2.6 mm
Answer:
r = 2.5 mm
Step-by-step explanation:
The circumference of a circle has the following formula.
circumference = 2πr
where
r = radius
π = 3.14
circumference = 15.9 mm
circumference = 2πr
15.9 = 2 × 3.14 × r
15.9 = 6.28 r
divide both sides by 6.28
r = 15.9/6.28
r = 2.53184713376
Rounding to 1 decimal place
r = 2.5 mm
For the years between 1980 and 2012, the function c(x)=0.006x^3−0.48x^2+12.8x+85 approximates the number of countries that attended the summer Olympics x years after 1980. Use the polynomial remainder theorem to approximate the number of countries that attended the Olympics in 2004.
Enter the answer in the box.
Answer:
199
Step-by-step explanation:
2004 is 24 years after 1980. The polynomial remainder theorem tells you the remainder from division by x-24 will be the function value c(24). We can find the remainder/function value by evaluating the function rewritten to Horner form:
c(x) = ((0.006x -0.48)x +12.8)x +85
c(24) = ((0.006(24) -0.48)(24) +12.8)(24) +85 = (-.336(24) +12.8)(24) +85
= 4.736(24) +85 = 198.664
c(24) ≈ 199
The approximate number of countries attending the 2004 Olympics was 199.

Answer: 4.6
Step-by-step explanation:
GH is equal to 4.6 since it is congruent to JH. GJ is one line, which makes angles GKH and JKH supplementary angles. Since angle GKH = 90, angle JKH must also equal 90, making these triangles similar. However, if you wish to see it done out mathematically, the following explanation is there:

Will be giving 30 pts, Brainliest, and thanks to anyone who answers plz help quick!!!!!!!!
Answer:
h( x ) = ( x + 1 )^2 - 4 x(h)×(÷×1)^2-4
Answer:
Step-by-step explanation:
Recognize from examining this function h( x ) = ( x + 1 )^2 - 4 that it is a quadratic function whose graph is a parabola that opens up. The vertex is at (h, k): (-1, -4). The axis of symmetry is the vertical line passing through the vertex: x = -1.
To find the y-intercept, let x = 0 and solve for y: h(0) = (0 + 1)^2 - 4 = -3. Thus, the y-intercept is (-3, 0).
To find the x-intercepts, set y = 0 and solve for x: 0 = h(x) = (x + 1)^2 - 4, or
(x + 1)^2 = 4. Taking the square root of both sides, we get x + 1 = ±2, whose roots are x = 1 and x = -3: (1, 0) and (-3, 0).
Graph all of these points and the axis of symmetry. Sketch the parabola that goes through these points.

Answer:
I think is the same formula area .A triangle is half as big as the rectangle that surrounds it, which is why the area of a triangle is one-half base times height.
Step-by-step explanation:
The area of a rectangle is given by the relation length* width. The area of a triangle is given by the relation (1/2)*base* height. Now we know that the two have the same area equal to 150 cm^2. Also, when placed on the same level the tip of the triangle touches the upper edge of the rectangle.
