the position of a particle moving along a coordinate line is s=√(3+6t), with s in meters and t in seconds. Find the particle's velocity at t=1 sec.
The particle's velocity at time t = 1 seconds is equal to 3 meters per seconds.
What is a position vs time graph?In Mathematics, a position vs time graph can be defined as a type of graph that is used to graphically represent the distance traveled (covered) by an object from its starting position with respect to the time when it is started moving.
Generally speaking, the position of a physical object (body) in a position vs time graph is always plotted on the y-coordinate (y-axis) while time is always plotted on the x-coordinate (x-axis).
From the information provided about this particle on a position vs time graph, we have;
s =√(3 + 6t)
Where:
s in meters.t in seconds.Substituting the given parameters into the formula, we have;
s =√(3 + 6(1))
s =√(3 + 6)
s =√9
Distance, s = 3 meters.
Now, we can determine the velocity as follows;
Velocity = distance/time
Velocity = 3/1
Velocity = 3 meters per seconds.

The coefficient of determination of a set of data points is 0.83 and the slope of the regression line is -1.38. Determine the linear correlation coefficient of the data.
The linear correlation coefficient of the data is calculated to be -0.911 as the slope of the regression line is -1.38
As the coefficient of determination that is (R^2) = 0.83 and the slope of the regression line = - 1.38, we can determine the linear correlation coefficient of the data as follows;
The Coefficient of determination (R^2) is the square of the linear correlation Coefficient (R) and is used to acquire the proportion of explained variance of the regression line.
Hence. To get the linear correlation Coefficient (R) from the Coefficient of determination (R^2); we take the square root of R^2 as follows;
R = √R^2
R = √0.83
R = 0.91104335791
R = 0.911
As the value of the slope is negative, therefore this represents a negative relationship between the variables, hence R will also be negative ;
Therefore, R = -0.911

Answer:
To find the fourth term in the given sequence, we can use the formula for the nth term, which is a^n = 2 (a^n-1) + 4. We can then plug in the value of a^1, which is 3, and the value of n, which is 4, to find the fourth term:
a^4 = 2 (a^3) + 4
= 2 [2 (a^2) + 4] + 4
= 2 [2 [2 (a^1) + 4] + 4] + 4
= 2 [2 [2 (3) + 4] + 4] + 4
= 2 [2 [10] + 4] + 4

Using the Central Limit Theorem, it is found that the correct option is
a. The expected values of R and S will be equal, and the variability of R will be less than the variability of S.
What is the Central Limit Theorem?
A sufficiently high sample size from a population with a finite level of variance will result in a mean of all samples from that population that is roughly equal to the population mean, according to the CLT, a statistical theory.
According to the central limit theorem, the distribution of the sample means will be roughly normally distributed if you take sufficiently large random samples from a population with mean and standard deviation and replacement.
The samples in this issue were drawn from the same population, thus they all had the same expected value.
R has less variability because there are more samples available.

Question 26 options:
y = –x + 2
y = x
y = x + 3
y = –x – 7
y= - x + 2.
Step-by-step explanation:1. Find the slope of the given line.The slope of any linear equation will always be the coefficient of the "x" variable when the equation is solved for "y". Since there isn't any number written to the left of "x", the slope of the line is 1.
2. Find the slope of the new line.When looking for the slope of a line perpendicular do another, take the value of the slope and find its multiplicative inverse and change the sign of this value as well. This is how you do it:
Original slope value: 1.

Use implicit differentiation to find an equation of the tangent line to the curve at the given point.
9x2 + xy + 9y2 = 19, (1, 1) (ellipse)
y = ________________?
The equation of the tangent line to the ellipse 9x^2 + xy + 9y^2 = 19 at the point (1, 1) is y = -18x + 19, which can be found using implicit differentiation.
We can find the equation of the tangent line to the ellipse 9x^2 + xy + 9y^2 = 19 at the point (1, 1) using implicit differentiation. Firstly, we take the partial derivatives of both sides of the equation with respect to x and y, which gives us y' = (9x + y)/(9y +x). Then, we plug in the given point (1,1) into the equation for y' and solve for y'. This gives us y' = (9 + 1)/(9 + 1) = 10/10 = 1. This means that the slope of the tangent line at this point is 1. We can then use the point-slope form of a line equation, y - 1 = 1(x - 1), to find the equation for the tangent line at this point, which is y = -18x + 19.
y' = (9x + y)/(9y +x)
At the given point (1,1):
y' = (9 + 1)/(9 + 1) = 10/10 = 1
Equation of the tangent line:

In a table of values for a pattern, P=3 when n=1; the equations P=3n and 2n+1 might represent the pattern. So the option d "Both A and C" is correct option.
In the given question, In a table of values for a pattern, P=3 when n=1; which of the following equations might represent the pattern.
a) P=3n
b) P = n+3
c) P = 2n+1
d) P = 3-n
We find the pattern we firstly observe the given diagram closely.
We firstly check which option can given P=3 when n=1.
Firstly taking the option a.
P = 3n
Now put n=1, so
P = 3
Hence, the option one is following the condition.
Now taking the option b.
P = n+3
Now put n=1, so
P = 1+3
P = 4
Hence, the option b is not following the condition.
Now taking the option c.
P = 2n+1
Now put n=1, so
P = 2(1)+1
P = 2+1
P = 3
Hence, the option c is following the condition.
Now taking the option d.
P = 3-n
Now put n=1, so
P = 3-1
P = 2
Hence, the option d is not following the condition.
Hence, the option a and c is following the condition. So the option d "Both A and C" is correct option.
