If m^n=32, where m
and n are positive integers, find n^mn
The value of [tex]n ^ {mn}[/tex] = [tex]5^{10}[/tex] or 9765625.
An index is a number that is raised to power. It is written as a small number to the right and above the base number. Other names for the index are exponent or power.
The index of a number says how many times to use the number in multiplication.
[tex]m^n[/tex]=32
m and n are positive integers.
32 = 2 x 2 x 2 x 2 x 2
32 = [tex]2^5[/tex]
hence, m = 2 and n = 5.
Now, Let's find the value of [tex](n ^ m)^n[/tex].
[tex](n ^ m)^n = n^{m*n}[/tex]
= [tex]5^{2*5}[/tex]
= [tex]5^{10}[/tex] or

Each square below represents one whole.
(one square - all shaded in of 4)
(second square - 3 shaded in of 4)
What percent is represented by the shaded area?
Answer:
The percent being represented by the shaded area is [tex]175\%[/tex]
Step-by-step explanation:
The percent being represented by the shaded area can be calculated as follows
The first step is to evaluate the left square
Since each square represents one whole, and since the left square is all shaded in of [tex]4[/tex] then the percent being represented by the shaded area in the left square is
[tex]1=\frac{4}{4}=\frac{100}{100}=100\%[/tex]
The percent being represented by the shaded area in the first or the left square is [tex]100\%[/tex]
The second step is to evaluate the right square
Since the right or the second square is [tex]3[/tex] shaded in of [tex]4[/tex], then the fraction being represented by the shaded area in the second square is
[tex]\frac{3}{4}[/tex]
The third step is to convert [tex]\frac{3}{4}[/tex] into the percent form by the following equation
[tex]\frac{3}{4}=\frac{x}{100}[/tex]
Where [tex]x[/tex] is the percent value for the second square
Multiply both side by [tex]100[/tex] to isolate [tex]x[/tex]
[tex]\frac{3}{4}\times 100=\frac{x}{100}\times 100[/tex]
Simplify the equation
[tex]\frac{300}{4}=x[/tex]
Simplify the left side of the equation
[tex]75=x[/tex]
Since the value of [tex]x[/tex] is [tex]75[/tex], then the percent being represented by the shaded area in the second square is [tex]75\%[/tex]
The fourth step is to calculate the total percent being represented by the all shaded area
Since the total percent is the sum of the percent for the first square and the percent for the second square, then it follows
[tex]\text{Total percent}=100\%+75\%[/tex]
Simplify the equation
[tex]\text{Total percent}=175\%[/tex]
Hence the percent being represented by the shaded are is [tex]175\%[/tex]

What is an arithmetic progression?
An arithmetic progression or arithmetic sequence is a number sequence in which the difference between consecutive terms is constant. For example, the sequence 5, 7, 9, 11, 13, 15.. is an arithmetic progression with a common difference of 2.
The first 'n' terms will be 1, 2, 3, 4, 5, 6, ...., n
The above sequence is an A.P. because it has a constant common difference of '1' between each consecutive number.
So a = 1, d = 1
By using the standard formula, we get
[tex]S_n=\frac{n}{2}[2a+(n-1)d]\\\\S_n=\frac{n}{2}[2+(n-1)][/tex]
and for the last term
[tex]t_n=a+(n-1)d\\\\t_n=1+(n-1)[/tex]
Hence, the sum of the first 'n' terms can be expressed as[tex]S_n=\frac{n}{2}[2+(n-1)][/tex]
and the last term will be [tex]t_n = 1+(n-1)[/tex], where a is the first term of A.P. and 'd' is a common difference.

one card is to be selected at random from a deck of cards. find the probability that the card selected is: a) a 5 b) not a 5 c) a diamond or king d) a jack or queen e) a heart and a club f) a card greater than 6 and less than 9
The probability of outcome to be a 5 is 1/13. The probability of outcome not be 5 is 12/13. The probability of outcome to be a diamond or a king is 4/13. The probability of the outcomes to be a jack or a queen is 2/13. The probability of The outcome to be a heart and a club is 0 and the probability of the outcomes to be a card greater than 6 and less than 9 is 2/13.
A deck contains a total of 52 cards.
Total outcomes if the selected number of cards is one=52
Case A:
Each suit contain one 5 numbered card. There are four suits. Therefore, The required outcome would be 4.
Probability of an outcome is the ratio of desired outcomes to the total outcomes.
The probability of outcome to be 5, P(A):
P(A)=4/52
P(A)=1/13
Case B:
The total probability of outcomes=52/52=1
The probability of the outcome to be 5=1/13
Therefore, the probability of the outcome not to be 5, P(B):
P(B)=1-(1/13)
P(B)=12/13
Case C:
Each suit carries a king. Therefore, the probability of the outcome to be a king, P(M):
P(M)=4/52
P(M)=1/13
A suit carries 13 cards. Therefore, there will be 13 cards of diamonds.
The probability of the outcome to be a diamond, P(N):
P(N)=13/52
P(N)=1/4
The probability that the outcome is a king of diamonds, P(M[tex]\cap[/tex]N):
P(M[tex]\cap[/tex]N)=1/52
Hence, the probability that the outcome is a diamond or a king, P(M[tex]\cup[/tex]N):
P(M[tex]\cup[/tex]N)=P(M)+P(N)-P(M[tex]\cap[/tex]N)
P(M[tex]\cup[/tex]N)=(1/13)+(1/4)-(1/52)
P(M[tex]\cup[/tex]N)=16/52

Case D:
Each suit carries a Jack. Therefore, the probability of the outcome to be a jack, P(P):
P(P)=4/52
P(P)=1/13
Each suit carries a Queen. Therefore, the probability of the outcome to be a Queen, P(Q):
P(Q)=4/52
P(Q)=1/13
The probability that the outcome is a jack and a queen, P(P[tex]\cap[/tex]Q):
P(P[tex]\cap[/tex]Q)=0/52
P(P[tex]\cap[/tex]Q)=0
Hence, the probability that the outcome is a jack or a queen, P(P[tex]\cup[/tex]Q):
P(P[tex]\cup[/tex]Q)=P(P)+P(Q)-P(P[tex]\cap[/tex]Q)
P(P[tex]\cup[/tex]Q)=(1/13)+(1/13)-0
P(P[tex]\cup[/tex]Q)=2/13
Case E:
A card is never a heart and a club. Therefore, the probability of a card to be a heart and a club is 0.
Case F:
The numbers greater than 6 and less than 9 are the numbers between 6 and 9. The numbers between 6 and 9 are 7 and 8.
Each suit carries one 7 numbered card and one 8 numbered card. There is a total of 4 suits.

What is gravitational force?
Each body in the universe attracts other bodies towards itself with a force known as Gravitational Force
Gravitational force is a central force which depends only on the position of test mass from the source mass and always acts along the line joining the centres of two masses.According to Newton’s law of gravitation, “Every particle in universe attracts every other particle with a force whose magnitude is,
Directly proportional to product of their masses, i.e., F ∝ (M1M2)Inversely proportional to the square of the distance between their centre, i.e., (F ∝ 1/r²)On combining these equations, we get
F = G × [M1M2]/r²
F ∝ M1M2/r²
Now , r' = r/2 ( given)
so, F' ∝ (m1m2) / (r/2)²
F' ∝(4 m1m2) / r²
Thus F' = 4×F
So, we can conclude that, when distance is halved, force increases by 4 times.

In order to make profit of 1,200,000, the company should publish 180 copies of magazine.
The formula for the profit is given by:
Profit = revenues - total cost.
Meanwhile, the total cost consists of fixed cost and variable cost.
Total cost = fixed cost + price per unit x number of units sold
Parameters given in the problem:
Fixed cost = 600,000
variable cost = 50,000 per unit
selling price = 60,000 per copy
profit = 1,200,000
Let q be the number of copies sold, then:
Revenues = 60,000 q
Total cost = 600,000 + 50,000 q
Profit = 60,000 q - (600,000 + 50,000 q)
1,200,000 = 60,000 q - (600,000 + 50,000 q)

Lia must work at least 5 hours per week in her family’s restaurant for $8 per hour. She also does yard work for $12 per hour. Lia’s parents allow her to work a maximum of 15 hours per week overall. Lia’s goal is to earn at least $120 per week.
Write a system of inequalities to represent this situation. Let r be the number of hours worked at the restaurant, and let y be the number of hours of yard work.
Graph the inequalities.
What is the maximum number of hours Lia can work at the restaurant and still meet her earnings goal? Explain.
What is the maximum amount of money Lia can earn in 1 week? Explain.
THE ASSIGNMENT IS ABOUT SYSTEMS OF INEQUALITIES
Answer:
Step-by-step explanation: (a)
(c)Maximum number of hours Lia can work at the restaurant and still meet her earnings goal = 15 hours
(d)Maximum Earning = $160
Step-by-step explanation:
Let r be the number of hours worked at the restaurant.
Let y be the number of hours of yard work,
Lia must work at least 5 hours per week in her family’s restaurant for $8 per hour.
Since she does yard work,
Lia’s parents allow her to work a maximum of 15 hours per week overall.
Lia’s goal is to earn at least $120 per week.
The restaurant, r pays $8 per hour
Yard work, y pays $12 per hour.
Therefore:
The system of inequalities that represent this problem is therefore:
(b)The graph of the inequality is attached below
(c)When the graph is plotted, the vertices of the feasible region are:
(5,10)
(5, 6.7)
(15,0)
Where the first term is for the number of hours worked in the restaurant.
The maximum value of r possible is 15 from the three points.
Therefore, she can work at the restaurant for 15 hours and still meet her earning goal.
(d)Maximum Amount Lia can earn in 1 Week
At (5,10), Earning=(5X8)+(10X12)=40+120=$160
At (5, 6.7), Earning=(5X8)+(6.7X12)=40+80.4=$120.4
At (15,0) Earning=(15X8)+(0X12)=$120
Since she has to work at least 5 hours at the restaurant, the maximum amount possible is $160.
