Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
Answer:
x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your
x^2 + (y – 3)^2 = 36 is correct (but only if you use " ^ " for exponentiation).

We have given that,
Two gymnasts are running toward each other in a floor routine, and they plan to precisely time a flip to stay synchronized for the audience.
What does synchronized motion mean?Synchronized motion is a motion of two or more system which goes in synchronization with each other.
For this case, the flip will occur such that both gymnasts are synchronized and the flip is in unison (simultaneous).
For that, we need the time(x) and the height (y) same.
Since the motion paths are:
\(y=-(x-5)^2+3\)
\(y=-3(x-3)^2+x+1\)
Therefore, we need to find the values of x for which the same y comes as output.
Let x = t be the time for which the height y is the same, then:
\(-(t-5)^2+3=-3(t-3)^2+t+1\) = height achieved by both gymnasts.
Solving it further:
\(-(t-5)^2+3=-3(t-3)^2+t+1\)
t=4,t=1/2
Assuming they planned to do a flip after an integral number of time in seconds, the correct option is t = 4 seconds.
Thus, to make sure the flip is in unison after 4 seconds should the flip occur, as given by the option C: 4 seconds.

What is the equation of the line that passes through the point (-6,-5) and has a slope of 3/2
Answer: actual answer is y=3/2x+4
Step-by-step explanation: plug b in the original formula
The equation of the line as of the condition given is y = 3x/2 + 3/2.
Given that,
The equation of the line that passes through the point (-6,-5) and has a slope of 3/2 is to be determined.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
The point-slope form of the line is given as,
y - y₁ = m (x - x₁)
From the given substitute the point and slope in the above equation,
y + 6 = 3/2 [x + 5]
y = 3x/2 + 15/2 - 6
y = 3x/2 + 3/2
Thus, the equation of the line as of the condition given is y = 3x/2 + 3/2.

An average human heart beats 60 times per minute. If an average person lives to the age of 75, how many times does the average heartbeat in a lifetime?
There should be ( ) heartbeats per lifetime.
(Enter your answer as a decimal number. Round to two decimal places.)
Answer:
The average number of beats in a lifetime would be 2,365,200,000
Step-by-step explanation:
To find the amount we need to take basic steps. The first step is multiplying the number of beats to find out how many are in an hour. Since there are 60 in a minute and 60 minutes in an hour, multiply the two.
60 beats * 60 minutes = 3,600 beats per hour.
Now multiply the amount of beats in an hour by the number of hours in a day.
3,600 * 24 hours = 86,400 beats per day
Now multiply the number of days in a year. Technically there is 365 1/4 in a year, but we'll use the flat rate of 365 since that is generally the accepted answer.
86,400 * 365 days = 31,536,000 beats per year
And now we take that number and multiply by the number of years that he lines
31,536,000 * 75 years = 2,365,200,00 beats in a lifetime
The heart beats 236,520, 000 times in a lifetime.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas. This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
An average human heart beats 60 times per minute.
Now, the amount of beats in an hour by the number of hours in a day.
= 3,600 x 24 hours
= 86,400 beats per day
Again, the amount of beats per year
= 86,400 x 365 days
= 31,536,000 beats per year
So, the heart beats
= 31,536,000 x 75 years
= 236,520, 000 beats in a lifetime

Choose the equation that would help Tisha find how many points they need to earn in the district match, b, to advance.
b equals T over 3 minus a minus c minus d
b equals T plus a plus c plus d all over 3
b equals T minus a minus c minus d all over 3
b = 3(T − a − b − d)
The points Tisha and her academic team would need to earn in the district match b to advance is;
Option C; b = (T - a - c - d)/3

The joint relative frequency is calculated by dividing the frequency of a specific subset (in this case, the number of adults who prefer watermelon) by the total number of data points.
Here, the specific subset is adults who prefer watermelon, which is 111. The total number of data points is the sum of all children and adults, regardless of fruit preference, which is 445.
So, to find the joint relative frequency of being an adult who prefers watermelon, you would divide 111 by 445.
Hence, the correct answer is:
C. Divide 111 by 445.

The cost to rent a sailing boat at Catalina Island is $370 per day
plus $80 for every hour of use. What is the maximum number of
hours the sail boat can be rented for each day, if the rental cost is
not to exceed $1090 per day?
Answer:
370 + 80x ≤ 1090
Step-by-step explanation:
By using letter variables for the unknown numbers, we can break down the question into mathematical terms:
If the cost is $370 per day and the number of days is unknown, we can substitute the number of days with a placeholder. In this case, it'll be a variable such as x. So the cost can be represented by $370y.
If the cost is $80 per hour and the number of hours is unknown, we can substitute the number of hours with a placeholder. In this case, it'll be a variable such as y. So the cost can be represented by $80x.
The questions asks for the total cost not to exceed $1090 per day. This means that we know that the number of days is 1. We're trying to find the maximum number of hours, so our equation will combine the costs of both day costs and hour costs:
$370 (1 day) + $80 (x hours) ≤ $1090 per day
The symbol is the equal to or less than symbol, meaning the combined total costs is either equal to $1090 or less than it.
To simplify this, we can rewrite it as:
370 + 80x ≤ 1090

The speed of the car is 108 kilometers per hour and the distance covered in 5 hours is 540 kilometers.
What is the speed of the car in kilometers per hour and distance covered after 5 hours?Speed is simply referred to as distance traveled per unit time.
It is expressed as;
Speed = Distance ÷ time.
Given that the car is traveling at a rate of 30 meters per second.
First, convert the car's speed from meters per second to kilometers per hour using the conversion factor.
1 kilometer = 1000 meters
1 hour = 3600 seconds
Hence;
Speed = 30m/s = ( 30 × 3600/1000 )kmh
Speed = 108 kmh
Next, the distance covered in 5 hours will be:
Speed = Distance / time
Distance = speed × time
Distance = 108 kmh × 5 h
