What is the value of b in the equation (yb) 4= 1/y24
Answer:
The value of b is [tex]\frac{1}{y^7}[/tex].
Step-by-step explanation:
Here the given expression is,
[tex](yb)^4=\frac{1}{y^{24}}[/tex]
[tex]y^4b^4=\frac{1}{y^{24}}[/tex] ( Using [tex](ab)^m=a^mb^m[/tex] on left side )
[tex]y^4b^4y^24 = 1[/tex] ( By cross multiplication )
[tex]y^{4+24}b^4=1[/tex] ( Using [tex]a^ma^n=a^{m+n}[/tex] on left side )
[tex]y^{28}b^4=1[/tex]
[tex]b^4=\frac{1}{y^{28}}[/tex]
[tex]b=(\frac{1}{y^{28}})^{\frac{1}{4}}[/tex] ( [tex]a^m=b^n\implies a=b^\frac{n}{m}[/tex] )
[tex]b=\frac{1^{\frac{1}{4}}}{(y^{28})^\frac{1}{4}}[/tex] ( [tex](\frac{a}{b})^m=\frac{a^m}{b^m}[/tex] )
[tex]b=\frac{1}{y^{28\times \frac{1}{4}}}[/tex] ( [tex](a^m)^n=a^{m\times n}[/tex] )
[tex]b=\frac{1}{y^7}[/tex]

Step-by-step explanation:
The distance formula is d = rt. A trip of 92 miles traveled at 65 mph will take 1.35 hours.
A. True
B. False
Then, the dot ran from −34 to −66. What distance did it cover? If this run took the dot 5 minutes, what was its average speed?
Final answer:
The dot covered a distance of 32 units when it ran from -34 to -66. Assuming the distance is measured in meters, and the dot took 5 minutes (300 seconds) to cover this distance, the average speed would be 0.1067 m/s.
Explanation:
To determine the distance the dot covered when it ran from -34 to -66, we need to calculate the absolute value of the difference between the two points. The formula for distance in this case is |final position - initial position|, so the distance covered = |-66 - (-34)| = |-66 + 34| = | -32 | = 32 units.
Now, to determine the average speed of the dot, we divide the total distance traveled by the time it took to cover that distance. Given that it took the dot 5 minutes to cover the distance, we convert minutes to seconds because speed is typically measured in meters per second (m/s) in physics. There are 60 seconds in a minute, so 5 minutes is 300 seconds. Therefore, the average speed is distance/time = 32 units / 300 seconds.
The exact units of measurement for distance have not been specified in the question, but assuming the distance is in meters (m), the average speed would be calculated as 32 m / 300 s = 0.1067 m/s.

Write three to five sentences explaining which levels of production provide Alonzo’s Cycling with the maximum profit.
The optimal level of production for Alonzo's Cycling is at the point where the profit reaches its peak before starting to decline with further increases in production. This is the level of production that Alonzo's Cycling should aim for to achieve the marginal profit.
To determine which levels of production provide Alonzo's Cycling with the maximum profit, one must consider both the fixed costs and the variable costs associated with production.
The profit for each level of production is calculated by subtracting the total costs (fixed costs plus variable costs) from the total revenue generated by sales. The level of production at which profit is maximized is where the difference between total revenue and total costs is the greatest.
This can be found by analyzing the marginal cost and marginal revenue of production. When marginal revenue equals marginal cost, and if the additional production leads to a decrease in profit, that is the point of maximum profit.
Beyond this point, producing more units would decrease the total profit due to the law of diminishing returns, where the cost of producing additional units exceeds the revenue they generate.
Therefore, the optimal level of production for Alonzo's Cycling is at the point where the profit reaches its peak before starting to decline with further increases in production. This is the level of production that Alonzo's Cycling should aim for to achieve the maximum profit.

x = 4 and y = -3.
Step-by-step explanation:
Given : 4x + 2y = 10 and 3x + 2y = 6.
To find : Solve the system algebraically. Check your work.
Solution : We have given that
4x + 2y = 10 ----(1)
3x + 2y = 6.------(2)
Subtracting equation 2 from 1
4x + 2y = 10
(-)3x + (-)2y =(-) 6.
_____________
x + 0 = 4
x =4
Plug x = 4 in equation 1
4 (4) + 2y = 10.
16 + 2y = 10.
2y = 10 -16.
2y = -6.
On dividing by 2 both sides
y = -3.
Check:
Plug the values x =4 , y =-3 in equation 1
4 (4) + 2 ( -3) = 10
16 -6 = 10
10 =10
Verify,
Therefore, x = 4 and y = -3.
What does the 80 inches represent in an 80" TV
The 80 inches on an 80" TV refers to the diagonal measurement of the screen, which determines the size of the TV. This measurement is essential for potential buyers to know to match the TV to their space and optimal viewing distance. Other factors like screen resolution and whether to choose plasma or LCD also influence the viewing experience and cost.
When we refer to an 80" TV, the 80 inches represents the diagonal measurement of the screen. This measurement is taken from one corner to the opposite corner of the screen, not horizontally or vertically, which is the standard for sizing televisions and monitors. The importance of considering screen size arises from the need to match the viewer's space and viewing distance to optimize the viewing experience. With larger screens, such as an 80-inch TV, viewers can enjoy a more immersive viewing experience, especially when watching sports, movies, or DVDs. However, depending on the resolution, like 1080p for full HD or 768p for a lower resolution, the quality of the image may affect the perceived difference in quality, especially on smaller screens in which it might not be distinguishable to the nak.ed eye.

find the difference 6x^2-14x+4/x(x-2) - 6x-1/x+1
Final answer:
To find the difference between two expressions in the given question, you need to simplify each expression first and then subtract them. The steps involve simplifying each expression separately and then performing the subtraction.
Explanation:
To find the difference 6x² - 14x + 4 / x(x - 2) - 6x - 1 / x + 1, you need to first simplify each expression and then subtract them from each other.
Step 1: Simplify each expression separately.
6x² - 14x + 4 / x(x - 2) = (3x - 2)(2x - 1) / x(x - 2) = 3(2x - 1) / x
- 6x - 1 / x + 1 = -6 - 1 / x + 1 = -7 / (x + 1)
Step 2: Subtract the two simplified expressions: 3(2x - 1) / x - 7 / (x + 1).
PART A: All but two of the pyramids built by the ancient Egyptians have faces inclined at 52 degree angles. Suppose an archaeologist discovers the ruins of a pyramid. Most of the pyramid has eroded, but the length of a side of the square base is 82 meters. How tall was the pyramid, assuming its faces were inclined at 52 degrees? Round your answer to the nearest meter.
25 m
32 m
52 m
105 m,
In the problem, we were asked to compute for the height of the pyramid. Given are the base of the pyramid which is 82 m and the angle of 52°.
If given an illustration, the height is opposite to the angle and the adjacent side is given by half the base.
Based on the mnemonics of trigonometry (SOH CAH TOA), the function to be used is tangent.
The computation is as follows:
Let h = height of pyramid (m)
tan52 = h/41
h = 41tan52
h ≈ 52.5 m
Hence, the height of the pyramid is approximately 52.5.
However, the closest answer based on the choices you provided is 52 m.

The number of animals in a population is 775, and it increases by of 51% each year.
a. Model the situation with an exponential function.
b. Find how many animals there will be in 10 years.
c. How many years will it take for the population to become 1150.
Show all work!
Answer(a):
Exponential growth formula is given by
[tex]A=P(1+r)^t[/tex]
Where preset population = P= 775
Rate of increase = r = 51% = 0.51
t= number of years
A= Future value.
Plug these values into above formula:
[tex]A=775(1+0.51)^t[/tex]
[tex]A=775(1.51)^t[/tex]
Hence required exponential function is [tex]A=775(1.51)^t[/tex]
Answer(b):
plug t=10 years
[tex]A=775(1.51)^t=775(1.51)^{10}=775(61.6267795034)=47760.7541151[/tex]
which is approx 47761.
Answer(c):
Plug A=1150
[tex]1150=775(1.51)^t[/tex]
[tex]\frac{1150}{775}=(1.51)^t[/tex]
[tex]\ln(\frac{1150}{775})=t*\ln(1.51)[/tex]
[tex]0.394654192004=t*0.412109650827[/tex]
0.957643654334=t
Which is approx 1 year.
which pair of triangles is congruent by AAS?
Answer:
Triangles PQT and RQT are congruent (option D)
Step-by-step explanation:
The AAS or Angle- Angle- Side Theorem says that if two angles and any side of one triangle are congruent to two angles and any side of another triangle, then the triangles are congruent.
So, triangles PQT and RQT are congruent.
Both triangles have angle Q as right angle and angle P and R are also equal. And both have side QT common.
So, these are congruent via AAS.
Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 5 m and diagonal QS = 6 m. Find the length of segment RP.
3 m
4 m
5 m
6 m
Answer:
Given: Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 5m and diagonal QS = 6m.
Since, diagonals of kite bisect each other, thus QP=6m
Now, in ΔPQR, we have
(QR)²= (RP)²+(QP)²
(5)²= (3)²+(RP) ²
25=9+(RP)²
25-9= (RP)²16= (RP)²
RP= 4m
Therefore, the length of segment RP is 4m.
