Answers
Answer:
A. True
Step-by-step explanation:
Given:
O is the center of the Circle
Chord BC is the line segment passing from the center of circle
Chord: It is a line segment whose end points lies on the circle.
Diameter: It is defined as a line segment passing from the center of the circle whose end point lies on the circle.
Hence chord BC is a diameter of the circle as passes from the center O of the circle and its end points B,C lies on the circle.
Hence the statement is TRUE
Yes, The chord BC is a diameter of circle C.
What is Line segment?Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.
We have to given that;
To check The chord BC is a diameter of circle C.
Now, WE know that;
The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Here, The line segment BC is passing through the center O.
Hence, The chord BC is a diameter of circle C.

Center:
Radius:
Answers
Answer:
Center: (-7, -4)
radius = 4
Explanation:
Equation: (x + 7)² + (y + 4)² = 16Circle formula:
(x - h)² + (y - k)² = r²(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
(x - (-7))² + (y - (-4))² = 4²From this identify:
h = -7, k = -4, radius = 4General equation
(x-h)²+(y-k)²=r²
So
(x+7)²+(y+4)²=16(x+7)²+(y+4)²=4²Center=(-7,-4)
Radius=4

Answers
Answer:
Step-by-step explanation:
11 + 5 = big hipo = 16
16 / x = x / 5
x*x = 16*5
x² = 80
x = [tex]\sqrt{80}[/tex] (do this lame calculus)
x = 4[tex]\sqrt{5}[/tex]
y² = (4[tex]\sqrt{5}[/tex])² - 5²
y² = (4[tex]\sqrt{5}[/tex]) * (4[tex]\sqrt{5}[/tex]) - 25
y² = 16 + 4[tex]\sqrt{5}[/tex] + 4[tex]\sqrt{5}[/tex] + [tex]\sqrt{25}[/tex] - 25
y² = 16 + 8[tex]\sqrt{5}[/tex] + 5 - 25

Graph a line representing the proportional relationship with slope 3 containing the point (2, 6).
To graph the line, plot two points on the line.
Answers
Answer:
(1, 3) and (0, 0)
Step-by-step explanation:
y = mx + b
m is the slope which is 3 (given)
b is the y intercept
(x, y) → (2, 6)
6 = 3(2) + b
6 = 6 + b
b = 0
so the equation is y = 3x

y = 3(1)
y = 3 when x = 1
(1, 3)
y = 3(0)
y = 0 when x = 0

Step-by-step explanation:
Part (a)This problem can be modeled as a right triangle (see attachment 1), where the wall and the ground are the legs, and the ladder is the hypotenuse. Therefore, we can use the sine trig ratio to find the angle.
Trig Ratio
[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = xO = wall = 9.2H = ladder = 10Substituting the given values into the ratio and solving for x:
[tex]\implies \sf \sin(x)=\dfrac{9.2}{10}[/tex]

[tex]\implies \sf x=67^{\circ}\:(nearest\:degree)[/tex]
Part (b)(see attachment 2)
Let y be the distance the foot of the ladder and the foot of the building
We can find y by using the cos trig ratio:

where:
[tex]\theta[/tex] is the angleA is the side adjacent the angleH is the hypotenuse (the side opposite the right angle)Given:
[tex]\theta[/tex] = 75°A = grounds = yH = ladder = 10Substituting the given values into the ratio and solving for x:

Five runners need to be arranged in 5 lanes for a race so that there is a runner in each lane. How many unique ways are there to arrange the runners in the 5 lanes?
Answers
Answer:
25
Step-by-step explanation:
When answer questions about unique combinations, there are usually two ways people go about finding the solutions.
First, sometimes it can take a while, but it often helps people visualize the question if they jot down or sketch each different combination. Then, they can just count them up at the end to find there answer.
The easeier way is to use a quick math trick. If you have 5 runners, with 5 potential lanes each runner could start in, you can just multiply these two variables together to get your answer of the number of possible options.
So,
5 runners * 5 lanes = 25 possible combinations for each lane and runner
The number of unique ways that the runner can be arranged in 5 lanes for a race is 120.
What are Combinations?Combinations are defined as the arrangement of objects or numbers in a way such that the order of the arrangement does not matter.
Total number of runners = 5
Total number of lanes = 5
Number of ways that 5 runners can be arranged = 5! = 120
Hence the number of ways is 120.

Answers
The new price of pizza when the quantity sold is increased to 250 is $12.45.
What is the new price of pizza?Price elasticity of demand measures the responsiveness of quantity demanded to changes in price of the good.
Price elasticity of demand = percentage change in quantity demanded / percentage change in price
Percentage change in quantity demanded = (250 / 200) - 1 = 25%
Percentage change in price = 25% / 1.5 = 16.67%
