Can someone help me pls
Answers
Answer:
No solution
Step-by-step explanation:
A solution for a system of equations entails that all variables are the same. In this case, it means that both x and y must be the same.
Looking at the graph, there is no spot where y=3x+3 and 3x-y=2 intersect
To confirm, we can look at the equations. If we make them both equal to y, we can set them equal to each other.
For y=3x+3, this is already set to y. For 3x-y=2, we can add y to both sides and subtract 2 from both sides to get
3x-2=y
3x+3=y
Since the x and y values must be the same, we can say that
3x-2=3x+3
subtract 3x from both sides
-2 = 3
Since -2 is not equal to 3, we can confirm that there are no solutions to this system of equations
Rachel has 37 videos and decides to purchase 2 more each week. Write an equation describing this situation.
Answers
T = 2w + 37
Step-by-step explanation:
Let T represent the total amount of videos Rachel has after w weeks
Rachel already owns 37 videos
She purchases 2 more each week
Therefore, after w weeks, the total amount of videos Rachel has can be represented by the expression:
2w + 37
Then the total after w weeks can be modeled by the equation:
T = 2w + 37

Find the third angle of a triangle if two of its angles are equal to:
25 degrees and 80 degrees
and
25 degrees and 120 degrees
Answers
Answer:
60 degrees
Step-by-step explanation:
Answer:
75 degrees, 35 degrees
Step-by-step explanation:
a. Adding 25 degrees and 80 degrees yields 105 degrees. The third angle of the given triangle must therefore be 180 degrees less 105 degrees, or 75 degrees.
b. Adding 25 degrees and 120 degrees yields 145 degrees. The third angle of the given triangle must therefore be 180 degrees less 145 degrees, or 35 degrees.
In a purely monopolistic market with a demand curve P = -Q / 10 + 2000, to maximize profit the firm provides the application at the output level:
Answers
Answer: hello your question lacks some data hence I will be making an assumption to help resolve the problem within the scope of the question
answer:
≈ 95 units ( output level )
Step-by-step explanation:
Given data :
P = 2000 - Q/10
TC = 2Q^2 + 10Q + 200 ( assumed value )
The output level where a purely monopolistic market will maximize profit
at MR = MC
P = 2000 - Q/10 ------ ( 1 )
PQ = 2000Q - Q^2 / 10 ( aka TR )
MR = d (TR ) / dQ = 2000 - 2Q/10 = 2000 - Q/5
TC = 2Q^2 + 10Q + 200 ---- ( 2 )
MC = d (TC) / dQ = 4Q + 10
equating MR = MC
2000 - Q/5 = 4Q + 10
2000 - 10 = 4Q + Q/5
1990 = 20Q + Q
∴ Q = 1990 / 21 = 94.76 ≈ 95 units ( output level )
Add.

C. Gregory's graph is incorrect because it shows 2 inches of growth for each week, when it should show 0.75 inches of growth each week
Step-by-step explanation:
Given that the plant grows 1.5 inches (y) every 2 weeks (x), it means that:
Rate of change = y/x = 1.5/2 = 0.75 inches per week
The graph he should create should have a rate of change of 0.75. that is, it should show 0.75 inches growth for every week.
The graph shown above has a rate of change of 2 inches per week.
Thus, the graph is incorrect. It should be showing 0.75 inches of growth per week instead of 2 inches.

Lets solve

Simplify[tex]\\ \sf\longmapsto w<-8[/tex]
Answer:
[tex]\boxed {\boxed {\sf w < -8}}[/tex]
Step-by-step explanation:
We are given an inequality and asked to solve for the variable w.
[tex]7w < -56[/tex]
In order to solve for w, we must isolate the variable. It is being multiplied by 7. The inverse of multiplication is division, so we divide both sides of the inequality by 7.
[tex]\frac {7w}{7} < \frac {-56}{7}[/tex]
[tex]w < \frac{-56}{7}[/tex]
[tex]w < -8[/tex]
w is less than -8 or w < -8.

what is soil erosion
Answers
Answer:
Soil erosion is the natural process in which the topsoil of a field is carried away by physical sources such as wind and water. In this process, the soil particles are loosened or washed away in the valleys, oceans, rivers, streams or far away lands.
It occurs when the impact of water or wind separates and removes soil particles, causing the soil to deteriorate. Soil deterioration and low water quality due to erosion and surface runoff have become severe problems worldwide.

Multiply both sides by x
X (Sin(50)) = 10
Then divide by (Sin(50))

Double Tower of Hanoi: In this variation of the Tower of Hanoi there are three poles in a row and 2n disks, two of each of n different sizes, where n is any positive integer. Initially one of the poles contains all the disks placed on top of each other in pairs of decreasing size. Disks are transferred one by one from one pole to another, but at no time may a larger disk be placed on top of a smaller disk. However, a disk may be placed on top of one of the same size. Let tn be the minimum number of moves needed to transfer a tower of 2n disks from one pole to another.
a. Find q and t2.
b. Find t3.
c. Find a recurrence relation for t1, t2, t3, ....
Answers
Answer:
a) t1 = 2 , t2 = 6
b) t3 = 14
c) recurrence relation ( Tn ) = 2Tn-1 + 2
Step-by-step explanation:
Tn = minimum number of moves needed
2n disks is moved from one pole to another
a) determine the value of t1 and t2
let n = 1
2n moves = 2 * 1 = 2
∴ t1 = 2
let n = 2
2n moves = 2*2 = 4
∴ t2 = 4 + t1 = 4 + 2 = 6
b) determine value of t3
let n = 3
2n moves = 2 * 3 = 6
∴ t3 = t1 + t2 + 6
= 2 + 6 + 6 = 14
c) Determine th recurrence relation
let n ≥ 2 i.e. n - 1 ≥ 1
number of disk required to be moved = 2n
number disks as follows : 1 to 2n
the recurrence relation = sum of number of moves in each step
Tn = Tn-1 + 2 + Tn -1
hence recurrence relation ( Tn ) = 2Tn-1 + 2 when all integers n ≥ 2
