Answer:
b^5
Step-by-step explanation:
When you are multiplying exponents with the same letter base, you simply just add the exponents.
for example, x^2 * x^3 = x^5
another example, y^6 * y^8 = y^14
An expression equivalent to b^3 * b^2 would be b^5

The Screaming Salamanders, a new rock band, released their new music video early for subscribers of their fan page. When the video was released to the public, it already had 2,642 views. One day later, the number of views increased to 3,963, and the band expects that the number of views will continue to grow each day. Write an exponential equation in the form y=a(b)x that can model the total number of views, y, x days after the music video was released to the public. Use whole numbers, decimals, or simplified fractions for the values of a and b.
The exponential equation is y=2,642(2.5)ˣ. x represents the number of days.
What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
Given that a video was released to the public, it already had 2,642 views.
One day later, the number of views increased to 3,963.
The number of viewers after one day is ( 3,963 + 2,642 ) = 6,605
Assume that the exponential function y = a(b)ˣ represents the number of viewers. x represents the number of days.
Putting x = 0 and y = 2,642 in y = a(b)ˣ:
2,642 = a(b)⁰
a = 2,642
Putting x = 1 and y = 6,605 in y = a(b)ˣ:
6,605 = a(b)¹
Putting a = 2,642:
6,605 = 2,642(b)¹
b = 6,605/2,642
b = 2.5
Therefore, an exponential equation is y=2,642(2.5)ˣ.

A factory has two smokestacks. The rate of particle pollution produced is 12 kg / h
for the first smokestack and 32 kg / h
for the second. The manufacturing process requires that the first smokestack operates 2
hours longer than 1. 5
times as long as the second. A local pollution control board has ordered that the factory produce no more than 374 kg
of particle pollution per day. What is the maximum number of hours per day that each smokestack can operate?
Maximum number of hours per day that first smokestack can operate 12.5 hours and for second smokestack is 7 hours.
According to the question a factory has two smokestacks:
Let first smokestack take x number of hours per day
and second smokestack take y number of hours per day
The rate of particle pollution produced is 12 kg/h for the first smokestack
and rate of particle pollution produced is 32 kg/h for the second.
A local pollution control board has ordered that the factory produce no more than 374 kg of particle pollution per day.
so, equation becomes 12x + 32y = 374
also the first smokestack operates 2 hours longer than 1. 5 times as long as the second.
so, x = 2 + 1.5y
putting value of x in other equation
12(2 + 1.5y) + 32y = 374
24 + 18y + 32y = 374
50y = 350
y = 7 hours
x = 2 + 1.5(7) = 12.5 hours

Flying to Kampala with a tailwind a plane averaged 158 km/h. On the return trip plane only averaged 112 km/h while flying back into the same wind. Find the speed of the wind and the speed of the plan in still air.
The speed of the plane is 135 km/h and wind speed is 23 km/h. The solution has been obtained by forming linear equations.
What is a linear equation?
This is the linear equation with the largest degree of one. This demonstrates that there are no variables in linear equations with exponents greater than 1. A straight line appears on the graph as a result of such an equation.
Let the plane speed be 'P' and the wind speed be 'W'.
We are given that while flying to Kampala with a tailwind a plane averaged 158 km/h.
So, we get an equation as
P + W = 158 ...(1)
Also, on the return trip plane only averaged 112 km/h while flying back into the same wind.
So, we get another equation as
P - W = 112 ...(2)
Now, on adding the equations we get,
⇒P + W + P - W = 158 + 112
⇒2P = 270
⇒P = 135
Now substituting the value into either equation, we get
⇒P + W = 158
⇒135 + W = 158
⇒W = 23
Hence, the speed of the plane is 135 km/h and wind speed is 23 km/h.

Y is directly proportional to x when y=30 x=6. Work out an equation connectng y and x
The equation connecting y and x when y is directly proportional to x and y = 30 when x = 6 is y = 5x.
If y is directly proportional to x, we can write the equation in the form:
y = kx
where k is the constant of proportionality.
To find k, we can use the values of y and x given:
y = 30, x = 6
When we enter these values into the formula above, we obtain:
30 = k * 6
Solving for k, we get:
k = 30/6 = 5
Therefore, the equation connecting y and x when y is directly proportional to x is:
y = 5x
When two variables are directly proportional, it means that when one variable increases or decreases, the other variable changes in the same proportion. In this scenario, we are given that y is directly proportional to x and we are also given a specific point on the line, (6, 30). Using this information, we can solve for the constant of proportionality k and write the equation connecting y and x as y = kx, where k is 5.

What is the average rate of change of the function -4≤x≤-3
Answer:
Step-by-step explanation:
The average rate of change of a function over an interval is equal to the total change in the function's output divided by the total change in the input over the interval. In other words, it is the slope of the secant line that connects the two points on the function defined by the interval.
If the function is represented by y = f(x), the average rate of change of the function over the interval [-4, -3] can be calculated as:
Δy / Δx = (f(-3) - f(-4)) / (-3 - (-4))
So, to calculate the average rate of change, you would need to know the values of the function f(x) at x = -3 and x = -4. If you provide the equation for the function f(x), I can help you find the average rate of change.

The Transformation of the "figure P" being translated 5 units to the right and 3 units up to create the "figure Q" is called as a type of "translation" in the coordinate plane.
When we shift a point (x, y) by "a" units to the right and "b" units up, the new coordinates become as ⇒ (x + a, y + b).
The coordinates of "figure P" is translated 5 units to the right and 3 units up, that means we will use the rule (x,y) → (x+5, y+3) to describe the transformation.

The above are resolved using the properties of Parallelograms; Rhombus, and Rectangle
Since the above answers are justified by the qualities or properties of :
Parallelograms; Rhombus, and Rectangle, lets look at them one by one.
2
a)
A = 8 - opposite sides of a parallelogram are equal in length
b = 10 -opposite sides of a parallelogram are equal in length
y = 62° - opposite angles of a parallelogram are of equal measure.
x = 118° - Sum of angles of a parallelogram - 360°. x = (360 - (62*2))/2
= 118°
3)
(a) Here we have a Rhombus.
∠2 = 25° - Opposite angles of a rhombus are equal; Diagonals bisect the angles of a rhombus. Thus ∠1≅∠2
∠3 = 65° - Since diagonals bisect each other at right angles, ∠3 = 180 - (25+90) = 65°
∠4 = 65° - Diagonals bisect the angles of a rhombus. Thus, ∠3≅∠3
∠5 = 90° - [properties of a Rhombus]
(b)
since SL = 10,
i) LT 10 - All sides of a Rhombus are equal
ii) TM = 10 - All sides of a Rhombus are equal
iii) SM = 10 - All sides of a Rhombus are equal
4) Here we have a Rectangle.
a) Since m∠18
∠2 = 18° because The diagonals bisect each other; and both the diagonals have the same length. Thus, m∠2≅∠1 (AAS)
∠3 = 72° - Each interior angle is equal to 90 degrees. Thus, m∠ = 90-18 = ∠72°
∠4 = 72° - because The diagonals bisect each other; and both the diagonals have the same length. Thus, m∠4≅∠3(AAS)
If FA = 27, then LO = 13.5 - The diagonals bisect each other.Thus,

the following data represent the monthly phone use, in minutes, of a customer enrolled in a fraud prevention program for the past 20 months. The phone company decides to use the upper fence as the cutoff point for the number of minutes at which the customer should be contacted. what is the cutoff point?
321 474 461 548
406 464 517 311
534 425 377 505
322 435 410 513
499 354 307 363
For the given data, the cutoff point using the upper fence is 791.25 minutes.
To find the cutoff point using the upper fence, we need to first calculate the lower and upper fences.
The lower fence is given by the formula:
Lower fence = Q1 - 1.5 x IQR
where Q1 is the first quartile and IQR is the interquartile range.
The upper fence is given by the formula:
Upper fence = Q3 + 1.5 x IQR
where Q3 is the third quartile and IQR is the interquartile range.
To find these values, we first need to order the data:
307 311 322 321 354 363 377 406 410 425
435 461 464 474 499 505 513 534 548
The first quartile (Q1) is the median of the lower half of the data:
Q1 = (354 + 363) / 2 = 358.5
The third quartile (Q3) is the median of the upper half of the data:
Q3 = (513 + 534) / 2 = 523.5
The interquartile range (IQR) is the difference between the third and first quartiles:
IQR = Q3 - Q1 = 523.5 - 358.5 = 165
Now we can calculate the lower and upper fences:
Lower fence = Q1 - 1.5 x IQR = 358.5 - 1.5 x 165 = 91
Upper fence = Q3 + 1.5 x IQR = 523.5 + 1.5 x 165 = 791.25
Therefore, the cutoff point using the upper fence is 791.25 minutes. Any customer who uses more than 791.25 minutes in a month should be contacted by the phone company as part of the fraud prevention program.

a researcher tests the effect of a new laparoscopic treatment for chronic shoulder dislocation, comparing it with an older treatment. the results are statistically significant, and the researcher states in the study findings that there is evidence that the treatment has promise for widespread application. a subsequent replication study fails to show statistical significance. a third and fourth study produce the same effects as the second. sample sizes are determined to be sufficient in all four studies. what is the most likely explanation here?
The most likely explanation for the inconsistency between the first and second studies is that the initial findings were a false positive, meaning that the effect observed was not actually present in the population being studied.
In the given scenario, the researcher tested a new laparoscopic treatment for chronic shoulder dislocation and found statistically significant results compared to an older treatment. This means that the difference between the two treatments was not due to chance and is likely to be a real effect.
However, a replication study failed to show statistical significance, which means that the difference between the two treatments could have been due to chance. This can happen even if the sample sizes were sufficient in all four studies. A lack of statistical significance in a replication study indicates that the effect observed in the first study may not be as strong or consistent as previously thought.
The fact that the third and fourth studies produced the same effects as the second could be attributed to random variation or other factors such as study design, sample selection, or measurement methods.
Statistical significance is a crucial concept in research as it helps to establish the credibility of a study's findings. However, it is important to understand that statistical significance alone does not necessarily mean that the effect observed is meaningful or important in practical terms.
