1. The elements of the set are {m, I, s, p}
The elements of the set are the letters in Mississippi. Elements cannot repeat themselves.. So the elements of this set would be {m, I, s, p} since all the other letters are just repetitions.
2. Set of months in a year are
{January,February,March,April,May,June,July,August,September,October,November,December}
3. Verbal Descriptions: It is a verbal description of the set is an English sentence to specify a law that allows us to decide the category of objects to be addressed and to determine whether it is in the set for any particular object.
Since, 3, 6 and 9 are divisible by 3 also less than 10.
4. Verbal description of the set {a,e,i,o,u} is vowels
In English these five alphabets{a,e,i,o,u} are known as vowels .
since the given set contains only vowels.
5. Yes (1,3,5) is the subset of odd integers.
The set of odd integers is the superset containing elements :-
Let A = { 1 , 3 , 5 , 7 , 9 ,..... ,( 2n + 1 ) }
And,
B = { 1 , 3 , 5 }
B is a subset of A because all elements of B lie in A .

The derivative of a function, f(x), at a point where f(x) has a sharp turn (or cusp) does not exist.
The derivative of a function, f(x), at a point where f(x) has a vertical tangent line does not exist.
Using this information, we can see that f(x) is not differentiable when x=3 since there is a vertical tangent line. We can also see that f(x) is not differentiable when x=-1 since there is a cusp.

Answer:
Range is 12 and mean is -6
Step-by-step explanation:
To find the mean, add together all the numbers and divide by 7.
the numbers to order them from greatest to least sqrt(29); (sqrt(6))/4; 19/7 1.538392 ...
The order of numbers from Greatest to Least is 5.385, 2.714, 1.538, 0.612.
Descending Order :Arranged in a series that begins with the greatest or largest and ends with the least or smallest.
We can also call it Greatest to Least.
To order the number from greatest to least first we have to find the value of given square root,
√29 = 5.385
√6/4 = 0.612
19/7 = 2.714
Now, we have the numbers :
5.385, 0.612, 2.714, 1.538
So, we will arrange the above numbers greatest to least
1) 5.385
2) 2.714
3) 1.538

We are given that:
The parking garage charges $ 3 per hour if the car is parked there for less than 2 hours.
So, we get that:
Parking fees = 3 x for 0 ≤ x ≤ 2
Now, we get that, if the car is parked for more than 2 hours and less than 5 hours, then the parking fee is
6 + 4 ( x - 2) for 2 < x ≤ 5
Now, we are given that it charges a fixed fee of $ 20 if car is parked for more than 5 hours. So, the parking fee will be
20 for x > 5
So, the function becomes:
f ( x ) = 3 x ; 0 ≤ x ≤ 2
f ( x ) = 6 + 4 ( x - 2) for 2 < x ≤ 5

The polynomial function f(x) has degree 4, a y-intercept of 40, roots of -5 and 4, and a multiplicity 2 root of 1. Enter f(x).
the graph of the equation is shown
The polynomial is:
f(x) = -2*(x + 5)*(x - 4)*(x - 1)*(x - 1)
How to get the polynomial function?Let's assume the leading coefficient is A, we know that the degree is 4, the y-intercept is 40, and we have the roots (-5, 4, 1, 1)
Then the polynomial is:
f(x) = A*(x + 5)*(x - 4)*(x - 1)*(x - 1)
Now we use the fact that the y-intercept is 40, so we have:
f(0) = 40 = A*(0 + 5)*(0 - 4)*(0 - 1)*(0 - 1)
40 = A*-20

For a collection to be termed as a set, it is necessary that it has distinct objects that are defined.
For example, a set of first 10 natural numbers is
A= [1,2,3,4,5,6,7,8,9,10]
It is well defined and therefore called as set which has first 10 natural numbers as its elements.

Find the angle measures.
Answer:
1. m ∠ 1 = 86°

Step-by-step explanation:
I'm confused, so I'll just solve both problems (assuming that they are the same type of angle)
1.
m Z1 = (x+84)° and m2 = 2xº.
m ∠ 1 = (x + 84)°
m ∠ 2 = 2x°
Complementary angles are equal to 90°
(x + 84) + 2x = 90

m ∠ 2 = 2(2)°
m ∠ 2 = 4°
2. (Problem in the picture)
m ∠ 1 = (x - 6)°

Expressed as a product of its prime factors in index form, a number n is n = 3 times 5 squared times x cubed. express 5n squared as a product of prime factors in index form. give your answer in terms of x.
5n² can be expressed as, 5n² = 3² x 5⁵ x x⁶
Given that n can be written as the product of the primes as
n = 3 x 5² x x³
This expression for n is called the prime factorization of n.
We need to express 5n² as such a product of primes.
For that taking square of n, add the power 2 with the existing powers of 3,5 and x,
So, n² = ( 3 x 5² x x³)² = 3² x 5⁴ x x⁶
So 5n² = 5(3² x 5⁴ x x⁶)

Maggie Travers works in the town's sanitation department. She is on a group health plan provided by the state for municipal employees. The insurance costs $6700 annually. The state pays 40% of the cost. Maggie is paid semi-monthly. How much should she expect to be deducted from her pay each paycheck for health insurance?
Answer:
$167.50
Step-by-step explanation:
Since the state pays 40% of the health insurance, Maggie will have to pay 100 - 40 = 60% of the insurance amount annually
60% = 0.6 decimal
So Maggie pays 0.6 x 6700 = $4,020
Maggie is paid semi-monthly ie 2 paychecks a month
In a year, there are 12 months so Maggie receives 24 paychecks annually
The total insurance amount of 4020 is split over 24 paychecks
So each paycheck deduction will be 4020/24 = $167.50

find the angle between a diagonal of a cube and an adjacent edge. (enter your answer in degrees. round your answer to two decimal places.)
The angle between a diagonal of a cube and an adjacent edge is 54.75°;
Assuming the length of a side of the cube as 1 unit, the three sides are given by the vectors;
a = (1, 0, 0)
b = (0, 1, 0)
c = (0, 0, 1)
The diagonal is given by the vector, v = (1, 1, 1)
The angle between the diagonal and one edge of the cube is given by
cos θ = v. a / |v|.|a|
v. a = (1, 1, 1).(1, 0, 0)
= 1(1) + 1(0) + 1(0
= 1 + 0 + 0
v. a = 1
Magnitude of vector V = √[(1)² + (1)² + (1)²]
|v| = √3
Similarly, |a| = √1;
So, |v|.|a| = √3.√1 = √3
Now, cos θ = 1/√3
So, θ = cos¹(1/√3)
θ = 54.75°
Therefore, the required angle is 54.75°.

Remy walked to a friends house, m miles away, at an average rate of 4mph. The m-mile walk home was at only 3mph. Remy spent 2 hours walking in all. Find the value of m.
Step-by-step explanation:
speed = mph or miles/hour
so, when we are dealing with a distance and compare the time spent on the distance, we have to divide distance by speed
miles / miles/hour = hour
so, we have
m/4 + m/3 = 2
as the sum of the time it took to walk the distance at 4mph and the time it took to walk the distance at 3 mph is 2 hours.
now we multiply by the denominators one after the other to eliminate the fractions.
m + 4m/3 = 8
3m + 4m = 24
7m = 24
m = 24/7 = 3.428571429... miles

8 cups has a height of
16.4cm
What would be
the height of
10 cups ?
Let the height of the cup be h and the extra length be d.
So, when the one cup is placed over another the total height will be h+d.
So, when the one cup is placed over another the total height will be h + d.
When the four cup is placed over each another h + 3d = 11 cm.
So the generalised equation will h +(n-1)d where n is the total number of cups.
When the eight cup is placed over each another = h + 7d = 16.4 cm
h + 3d = 11 cm
h + 7d = 16.4 cm
On solving the above two equation we will get d = 1.35 cm and h = 6.95 cm
So when we put 10 cups on each other = h +9d
