(3, 9) and (0, 3)
Slope = (Y2 -Y1) ÷ (X2 -X1)
Slope = (3-9) / (0-3)
Slope = -6 / -3
Slope = 2
The equation will have the form y = mx + b
We can rearrange this to b = y -mx
Let's take one of the points (3, 9) and the slope (m) and enter it into the formula:
b = -9 -2*3
b= -3
Now we enter all that data into b = y -mx
and get
y = 2x -3

The Hamptons family has a fish tank holding 10,450 ml of water. The water is leaking at a rate of 270 ml per minute. Define the input and output in the given scenario
Answers
The input is any variable which goes into the system. In this case there is no input.
While the output is any variable going out of the system. In this case the output is the amount of water which leaked out.
Answer:
The number of minutes represents input and remaining water represents output.
Step-by-step explanation:
Given,
The original quantity of the water in the tank = 10,450 ml,
Also, the quantity of the water leaked per minute = 270 ml,
Thus, the quantity water leaked in x minutes = 270x
∵ Remaining water in the tank ( say y ) = Original water - leaked water
⇒ y = 10450 - 270x,
Which is the equation that shows the given scenario.
In this equation, x represents the input value and y represents the output value,
Hence, the number of minutes represents input and remaining water represents output.

Find an equation of a linear function given h(1)=6 and h(4)=-3
Answers
We can rewrite this in the form of h (t):
at t = 1, h = 6
at t = 4, h = -3
The linear equation is in the form of:
h = mt + b
where m is the slope and b is the h-intercept
So calculating for the slope m:
m = [-3 – 6] / (4 – 1)
m = (-9) / 3
m = -3
So,
h = -3t + b
Solving for b by plugging in any pair:
6 = -3(1) + b
b = 9
Therefore:
h = -3t + 9

Using graphite furnace atomic absorption spectrometry, the mean cadmium (cd2 ) content value in a homogenized sample of 40 zebra mussles was found to be 7.50 ppb cd2 with a standard deviation (s) of 0.52 ppb cd2 (assume that s is a good approximation of σ). calculate the 90% and 95% confidence intervals (ci) for: (a) two analyses and (b) five analyses of this homogenized sample.
Answers
Given that the mean cadmium (cd2 ) content value in a homogenized sample of 40 zebra mussles was found to be 7.50 ppb cd2 with a standard deviation (s) of 0.52 ppb cd2
The 90% confidence interval for a sample of size n, with sample mean [tex](\bar{x})[/tex] and a standard deviation of s is given by:
[tex]90\%\ C.I.=\bar{x}\pm1.645\left( \frac{s}{ \sqrt{n} } \right)[/tex]
Thus, the 90% confidence intervals (ci) for two analyses is given by:

Where x is the number of ski trips you take.
1. When C = 315 ;substituting the value of C in the above equation.

=> [tex]85x=255[/tex]
x = 3 trips.
2. When C = 485

Whats the rule for this pattern, 3,1.5,0,-1.5,-3
Answers
Final answer:
The rule for the pattern 3, 1.5, 0, -1.5, -3 is to subtract 1.5 from the previous term in the sequence.
Explanation:
The rule for the number pattern 3, 1.5, 0, -1.5, -3 is subtracting 1.5 from the previous number each time. To identify this, observe the difference between consecutive terms:
From 3 to 1.5 we subtract 1.5 (3 - 1.5 = 1.5).
From 1.5 to 0 subtract 1.5 (1.5 - 1.5 = 0).
From 0 to -1.5 subtract 1.5 (0 - 1.5 = -1.5).
And from -1.5 to -3, again subtract 1.5 (-1.5 - 1.5 = -3).
This pattern consistently decreases by 1.5, and it can be continued indefinitely by keeping this rule in mind.

If r = x, y, z and r0 = x0, y0, z0 , describe the set of all points (x, y, z) such that |r − r0| = 5.
Answers
We are concern about the vector (x-x0, y-y0, z-z0) equaling to 5.
This happens when √(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 5
Square both side:
(x-x0)^2 + (y-y0)^2 + (z-z0)^2 = 25 , a sphere
Which you will recognize as a circle of radius one centered at (x0, y0, z0)
Answer:
Point [tex]\left ( x,y,z\right )[/tex] represents a sphere
Step-by-step explanation:
Take [tex]r=\left ( x,y,z \right )\,,\,r_0=\left ( x_0,y_0,z_0 \right )[/tex]
We need to describe the set of all points (x, y, z) such that [tex]\left | r-r_0 \right |=5[/tex]
Solution :
For [tex]r-r_0=\left ( x,y,z \right )-\left ( x_0,y_0,z_0 \right )[/tex], we will subtract the respective elements .
[tex]r-r_0=\left ( x,y,z \right )-\left ( x_0,y_0,z_0 \right )=\left ( x-x_0,y-y_0,z-z_0 \right )[/tex]
Therefore, [tex]\left | r-r_0 \right |=\sqrt{(x-x_0)^2+(y-y_0)^2+(z-z_0)^2}[/tex]
As [tex]\left | r-r_0 \right |=5[/tex], we get
[tex]\sqrt{(x-x_0)^2+(y-y_0)^2+(z-z_0)^2}=5[/tex]
On squaring both sides, we get
[tex]\left ( \sqrt{(x-x_0)^2+(y-y_0)^2+(z-z_0)^2} \right )^2=5^2\\(x-x_0)^2+(y-y_0)^2+(z-z_0)^2=25[/tex]
The general equation of a sphere is (x - a)² + (y - b)² + (z - c)² = r², where (a, b, c) denotes the center of the sphere and r represents the radius .
So, [tex](x-x_0)^2+(y-y_0)^2+(z-z_0)^2=25[/tex] represents a sphere with center as [tex]\left ( x_0,y_0,z_0 \right )[/tex] and radius equal to 5 units

It takes the earth 24 hours to complete a full rotation. It takes mercury approximately 58 days, 15 hours, and 30 minutes to complete a full rotation. How many hours does it take mercury to complete a full rotation?
Answers
To answer this question you need to convert the mercury rotation time from 58 days, 15 hours, and 30 minutes into hours.
First, try to convert the days into hours. The calculation would be=
58 days x 24 hours/day= 1392 hours.
Then convert the 30 minutes into the hours.
30 minutes / (60 minutes/hour)= 0.5 hours
After that you just need to add them all, then hours need for mercury to complete a full rotation: 1392 hours + 15 hours+ 0.5 hours= 1407.5 hours.
Mercury takes approximately 1407.5 hours to complete a full rotation, calculated by converting 58 days, 15 hours, and 30 minutes entirely into hours.
Explanation:To calculate how many hours it takes for Mercury to complete a full rotation, we need to convert the given time of approximately 58 days, 15 hours, and 30 minutes into hours. Here are the step-by-step calculations:
First, convert the days into hours. Since there are 24 hours in a day, we multiply 58 days by 24 hours per day.58 days × 24 hours/day = 1392 hoursNext, add the additional hours to the total from the days.1392 hours + 15 hours = 1407 hoursFinally, convert the minutes to hours. There are 60 minutes in an hour, so we divide 30 minutes by 60.30 minutes ÷ 60 minutes/hour = 0.5 hoursAdd this to the total number of hours.1407 hours + 0.5 hours = 1407.5 hoursTherefore, it takes Mercury approximately 1407.5 hours to complete a full rotation.
