Rewrite 154u as 2 · 7u · 11 :
[tex]\implies (7u)^2-2 \cdot 7u \cdot 11+11^2[/tex]
Compare with the form a² - 2ab + b²:
a = 7ub = 11Apply the perfect square formula: a² - 2ab + b² = (a - b)²
[tex]\implies (7u)^2-2 \cdot 7u \cdot 11+11^2=(7u-11)^2[/tex]
Suppose an object moves along the y axis so that its location is yequalsf(x)equalsxsquaredplusx at time x (y is in meters, x is in seconds). Find (A) The average velocity (the average rate of change of y with respect to x) for x changing from 2 to 5. (B) The average velocity for x changing from 2 to 2+h. (C) The instantaneous velocity at xequals2 second. (A) The average velocity is 8 m/sec. (B) The average velocity is (nothing )m/sec. (C) The instantaneous velocity is 5 m/sec.
When x changes from 2 to 5, the average velocity (or average rate of change of y with respect to x) is 9.33 m/s. When x changes from 2 to 2 + h, the average velocity is 2 + hm/s.
How can the average velocity be determined?Average speed is determined by dividing the total distance you travelled by the total time, whereas average velocity is determined by dividing your displacement (a vector Throughout the entire period, position to your finish position).
(A) The following formula is used to get the average velocity when x changes from 2 to 5:
value of y at x = 2
= 2²+2 = 6 m
value of y at x = 5
= 5²+5 = 30 m
displacement equals 30 – 6 = 24 m.
Time is 5 - 2 = 3 seconds.
average velocity
= displacement /Time duration
= 24/3 = m/s
B) Value of y at x = 2 = 5 for x changing from x to x plus ie for minimal change in x.
Displacement during a little change in x will be 0 because the value of y will once again be 5.
C )
y(x) = x² + x
dy / dx = 2x + 1
dy / dx represents instantaneous velocity
so when x = 2
instantaneous velocity = 2 x 2 +1
= 5 m /s

Using the unitary method, we found that the unit rate of slime is 0.2 cups per container.
What is meant by the unitary method?
The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, and then multiplying that value to determine the required value. Recognizing the units and values is crucial when using the unitary technique to a problem.
Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things. The unitary approach must be applied whenever we need to determine the ratio of one quantity to another.
Given,
Number of cups of slime = 7.2
Number of containers = 36
Unit rate = Amount of slime in each container
Using the unitary method we can find the unit rate.

the average rent of one bedroom apartment in brooklyn is 2700 in 2021,if rent will increase 2.5% in 2022 and 2.5% in 2023.what would be the average rent in 2023?
The average rent of a one-bedroom apartment in Brooklyn is estimated to be $2,836.69 in 2023 after the 2.5% increase in both 2022 and 2023
What is the percentage increase?
Percentage increase is a measure of how much a value or quantity has increased relative to its original value, expressed as a percentage.
To calculate the percentage increase, you can use the following formula:
Percentage increase = (New value - Old value) / Old value x 100%
If the average rent of a one-bedroom apartment in Brooklyn is $2,700 in 2021, and it increases by 2.5% in both 2022 and 2023, we can calculate the average rent in 2023 as follows:
Calculate the increase in rent due to the 2.5% increase in 2022:
2.5% of $2,700 = 0.025 x $2,700 = $67.50
The new rent in 2022 will be $2,700 + $67.50 = $2,767.50
Calculate the increase in rent due to the 2.5% increase in 2023:
2.5% of $2,767.50 = 0.025 x $2,767.50 = $69.19
The new rent in 2023 will be $2,767.50 + $69.19 = $2,836.69
Therefore, the average rent of a one-bedroom apartment in Brooklyn is estimated to be $2,836.69 in 2023 after the 2.5% increase in both 2022 and 2023.

Write the equation of the line in all three forms that is perpendicular to the line
6x+18y=36 and goes through the point (-5,4)
.
A system is made up of two subsystems, A and B, connected in-series (i.e., the system fails if either subsystem fails). Subsystem A is made up of components 1 and 2, connected in series. Component 1 fails according to a Poisson process with rate 0.2 per month, whereas component 2 fails as a Poisson process with rate 0.08 per month. Subsystem B is made up of a single component 3, which is subject to repeated disruptions. The disruptions arrive as a Poisson. process with rate 1.2 per month but only 20% of them cause the failure of component 3.
a) Find the probability that the system will fail during a 3-month period.
b) Find the probability that there will be no more than two failures of the system during a 6-month period.
c) Find the probability that the next system failure will occur within a year.
Answer: a) The probability that the system will fail during a 3-month period can be calculated as the sum of the probabilities of subsystem A and subsystem B failing, since the system fails if either one fails. The probability of subsystem A failing in 3 months is given by P(A) = 1 - e^(-0.2 * 3) * (1 + 0.2 * 3 + (0.2 * 3)^2 / 2!) = 0.0664. The probability of subsystem B failing in 3 months is given by P(B) = 1 - e^(-1.2 * 3) * (1 + 0.2 * 3 + (0.2 * 3)^2 / 2!) = 0.36. Therefore, the probability that the system will fail in 3 months is P(system) = P(A) + P(B) = 0.0664 + 0.36 = 0.4264.
b) To find the probability that there will be no more than two failures of the system during a 6-month period, we need to use the cumulative distribution function (CDF) of the Poisson distribution. Let X be the number of failures of the system in 6 months. The CDF is given by F(x) = P(X <= x) = 1 - P(X > x), where P(X > x) is the probability that there will be more than x failures. Therefore, the probability that there will be no more than two failures of the system during a 6-month period is given by F(2) = 1 - P(X > 2). We can use the formula for the Poisson distribution to find P(X > 2), which is P(X > 2) = e^(-6 * (P(A) + P(B))) * ((6 * (P(A) + P(B)))^3 / 3! + (6 * (P(A) + P(B)))^2 / 2! + 6 * (P(A) + P(B)) / 1! + 1). Plugging in the values for P(A) and P(B) from part (a), we get F(2) = 1 - e^(-6 * 0.4264) * ((6 * 0.4264)^3 / 3! + (6 * 0.4264)^2 / 2! + 6 * 0.4264 / 1! + 1) = 1 - 0.2079 = 0.7921.
c) To find the probability that the next system failure will occur within a year, we need to find the cumulative distribution function (CDF) of the time between failures, which is the sum of the time between failures of subsystem A and subsystem B. Let X be the time between failures of subsystem A, which follows an exponential distribution with rate 0.2 per month. Let Y be the time between failures of subsystem B, which also follows an exponential distribution with rate 1.2 * 0.2 = 0.24 per month. Then the CDF of the time between failures is given by F(t) = P(X + Y <= t) = 1 - P(X + Y > t0.2 * 12) * e^(-0.24 * 12) = 1 - 0.17 = 0.83. Therefore, the probability that the next system failure will occur within a year is 0.83.
