Both cyclist are moving apart at a speed of 9.434 mi/hr.
What is velocity?Velocity is the direction at which an item is moving and serves as a measure of the rate at which its location is changing as seen from a certain point of view and as measured by a specific unit of time (for example, 60 km/h northbound). In kinematics, the area of classical mechanics that deals with the motion of bodies, velocity is a basic idea. A physical vector quantity called velocity must have both a magnitude and a direction in order to be defined. Speed is the scalar absolute value (magnitude) of velocity; it is a coherent derived unit whose quantity is measured in metres per second (m/s or m/s1) in the SI (metric system).

An unreliable study can occur if the test administration is inconsistent
Consistency is the key to success in anything and it implies to the studies and surveys as well. If you want the results of the study to be reliable, then you must be consistent in test administration.
Inconsistency can lead to various issues like improper representation of the feedback which may alter the results. This can lead to various problems.
For example, test performed at certain time may have a different set of people and absence of periodic tests can accommodate feedback from irrelevant people.

When Point Q is on line segment PR, if PQ=x,QR=6, and PR =2x-10, then the length of PR is 18 units
Given,
That point Q is on line segment PR
The length of PQ = x
The length of QR = 6

he brazilian free-tailed bat can travel 99 miles per hour. after sunset, a colony of bats emerges from a cave and spreads out in a circular pattern. how long before these bats cover an area of 80,000 square miles? use π
The bat colony will cover an area of 80,000 square miles in 1.612 hours.
What is defined as the circle?A circle is the collection of all the points together in plane that are equally distant from the a given point known as the circle's center. A circle is represented by the symbol. A radius of a circle is a line segment that connects the center of a circle toward any point on the circle.
Now, as per the given question;
The area covered (A) by the colony, evaluated in square miles, is depicted by the mentioned geometrical formula as the bat colony emerges from a cave & spreads out in a circular pattern:
A = π R²
R = the bat's distance from the cave, calculated in miles.
Furthermore, each bat moves at a constant speed, and distance is depicted by the following kinematic formula:
R = r₀ + rΔt
r₀ = The bat's initial distance from the cave, estimated in miles.
r = Bat speed, estimated in miles per hour.
Δt = Time, expressed in hours.
Substitute the value of R in the formula of area.
A = π (r₀ + rΔt)²
(r₀ + rΔt)² = A/ π
(r₀ + rΔt) = √(A/ π)
rΔt = √(A/ π) - r₀
Δt = (√(A/ π) - r₀)/r
r = 99 miles per hour
The distance between the bat and the cave has now been substituted, and time has been cleared:
A = area of 80,000 square miles
π = 3.14
r₀ = 0 miles per hour
Substituting all the values in the A we calculate the time.
Δt = (√( 80,000/3.14) - 0)/99
On solving;
Δt = 1.612 (approx)
Thus, It will take 1.612 hours for the bat colony to cover an area of 80,000 square miles.

jack's age next year will be twice jill's age last year. their present ages total 45. how old is each no
We get the age of Jack is 29 years and the age of Jill is 16 years.
We are given that the sum of Jack's age and Jill's age is 45 years.
Let Jack's age be x.
Let Jill's age be y.
x + y = 45
x = 45 - y
Now, we are also given that jack's age next year will be twice Jill's age last year.
Jack's age next year = x + 1
Jill's age last year = y - 1
ATQ, We get the equation as:
x + 1 = 2( y - 1)
x + 1 = 2 y - 2
x = 2 y - 2 - 1
x = 2 y - 3
We get that:
45 - y = 2 y - 3
2 y + y = 45 + 3
3 y = 48
y = 48 / 3
y = 16 years.
x + y = 45
x + 16 = 45
x = 45 - 16
x = 29 years.
Therefore, we get the age of Jack is 29 years and the age of Jill is 16 years.

shown in the table.
Necklace Chains
Bracelet Chains
What are the x and y intercepts of the function modeling the number of bracelet chains chloe can purchase given the number of necklace chains that she buys?
Using a linear function, it is found that:
The x-intercept is of 28.125.The y-intercept is of 45.What is a linear function?A linear function is modeled by the following rule:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, the change in y divided by the change in x.b is the y-intercept, which is the the value of y when the function crosses the x-axis, that is, when x = 0.From the table, we have that:
The input is the number of necklace chains.The output is the number of bracelet chains.Hence, we have that when x = 0, y = 45, meaning that:
The y-intercept is of 45.
When x increases by 5, y decays by 8, hence the slope is given as follows:
m = -8/5 = -1.6.
Then the function is:
y = -1.6x + 45.
The x-intercept is found as follows:
-1.6x + 45 = 0
1.6x = 45
x = 45/1.6
x = 28.125.
The x-intercept is of 28.125.

Answer: B
Step-by-step explanation:
Here is a rule that can be used to build a sequence of numbers once a starting number is chosen: Each number is two times three less than the previous number.
a. Starting with the number 0, build a sequence of 5 numbers.
b. Starting with the number 3, build a sequence of 5 numbers.
c. Can you choose a starting point so that the first 5 numbers in your sequence are all positive? Explain your reasoning.
Answer:
a. 0, -6, -18, -21, -90
b. 3, 0, -6, -18, -42
c. A starting point of any number ≥ 6 will result in a sequence of positive values
Step-by-step explanation:
Here the sequence is governed by the rule:
[tex]\sf a_{n} = 2(a_{n-1} - 3)[/tex]
[tex]\textsf {where $a_n$ is the nth term and $a_{n-1}$ is the previous term}}[/tex]
1) Starting with a₁ = 0 we get
a₂ = 2(a₁ - 3) = 2(0 - 3) = -6
a₃ = 2(a₂ - 3) = 2(-6 -3) = 2(-9) = -18
a₄ = 2(a3 - 3) = 2(-18 - 3) = 2(-21) = -42
a₅ = 2(a₄ - 3) = 2(-42- 3) = 2(-45) = -90
So the first 5 numbers in the sequence starting with 0 are:
0, -6, -18, -21, -90
2) I will approach this slightly differently
We have the relationship:
[tex]\sf a_{n} = 2(a_{n-1} - 3)[/tex]
Expanding the brackets we get
[tex]\sf a_{n} = 2a_{n-1} - 6[/tex]
We have a₁ = 3
a₂ = 2(a₁) - 6 = 2(3) - 6 = 6 - 6 = 0
a₃ = 2(a₂) - 6 = 2(0) - 6 = -6
a₄ = 2(a₃) - 6 = 2(-6) - 6 = -18
a₅ = 2(a₄ ) - 6 = 2(-18) - 6 = -42
The sequence starting with 3 is:
3, 0, -6, -18, -42
Both methods work exactly the same, some students find expanding the brackets easier to deal with
c. We can see that as a₁ increases, the number of negative numbers decreases by 2. So, in order for all numbers to be positive (> 0) we should start with a sufficiently large number so that all numbers are positive
The smallest such number is 6.
When a₁ = 6, the sequence is all 6s because
a₂ = 2(6) - 6 = 12 - 6 = 6
So the next number is a₃ = 12(6) - 6 = 6 and so on
So any starting point ≥ 6 will yield positive values. At 5 the sequence would be: 5, 4, 2, -2, -10 so starting point of 5 will not work
