Marcus states that the polynomial expression 3x3 – 4x2y + y3 + 2 is in standard form. Ariel states that it should be y3 – 4x2y + 3x3 +2. Explain which student is correct and why.
Answers
Answer:
They are both correct because there is more than one way to write a multivariable polynomial in standard form. Marcus has the exponents on the x variable in descending order from the highest degree to the lowest degree. Ariel has the exponents on the y variable in descending order from the highest degree to the lowest degree.

Find Value of y.
Answers
=====================================
Work Shown:
EI = EG
3y-10 = 2y
3y-10-2y = 0
y-10 = 0
y = 0+10
y = 10
Note how if y = 10, then
EI = 3y-10 = 3*10-10 = 20EG = 2y = 2*10 = 20Both EI and EG are 20 units long when y = 10. This confirms the answer.

The area of a rectangle is 1,872 ft2. The ratio of the length to the width is 9:13. Find the perimeter of the rectangle. A. 88 ft B. 117 ft C. 168 ft D. 176 ft
Answers
Answer:
Length = 36
Width = 52
Step-by-step explanation:
Area of rectangle = Length * width
Length = L ; Width = W
Area (A) = 1872 ft²
Ratio L:W = 9:13
Hence,
1872 = lw - - - (1)
l/w = 9/13 - - - (2)
From (2)
13l = 9w
l = (9/13)w - - (3)
Put (3) into (1)
1872 = (9/13)w * w
1872 = 9/13 w²
24336 = 9w²
24336 / 9 = w²
2704 = w²
w = 52
If w = 52
1872 = 52 * l
l = 1872 / 52
l = 36
Length = 36
Width = 52

A 20 foot ladder is placed against a wall at a 75 degree angle with the ground. The wall is perpendicular to the ground.
PART A: How high on the wall, in feet, will the ladder reach? Round your answer to the nearest tenth. Show your work.
PART B: What is the distance, in feet, from the wall to the base of the ladder? Show your work.
Answers
Answer:
Part A)
Height = 19.3 feet
Part B)
Distance = 5.2 feet
Step-by-step explanation:
Part A)
Let ladder reaches upto the h height of the wall.
[tex] \therefore \sin \theta =\frac{h}{length\: of\: the \:ladder} [/tex]
[tex] \therefore \sin 75\degree =\frac{h}{20} [/tex]
[tex] \therefore 0.9659258263 =\frac{h}{20} [/tex]
[tex] \therefore 0.9659258263\times 20 = h [/tex]
[tex] \therefore 19.3185165 \: ft= h [/tex]
[tex] \therefore h = 19.3 \: ft= h [/tex]
Part B)
Let the distance from the wall to the base of the ladder be x feet.
[tex] \therefore \cos \theta =\frac{x}{length\: of\: the \:ladder} [/tex]
[tex] \therefore \cos 75\degree =\frac{x}{20} [/tex]
[tex] \therefore 0.2588190451 =\frac{x}{20} [/tex]
[tex] \therefore 0.2588190451\times 20 = x [/tex]
[tex] \therefore 5.1763809 \: ft= x [/tex]
[tex] \therefore x = 5.2 \: ft [/tex]

Answers
Answer:
A number that can be written as the ratio of two integers .
Step-by-step explanation:
Irrational numbers are numbers those numbers that have infinite non-periodic decimals, that are reproduced in an unlimited way without an end point, without any part of the sequence being repeated. The set of irrational numbers, added to the rational numbers, configures the category of real numbers.
Irrational numbers include, for example, the famous number Phi (π), whose approximate value is 3.14 ..., extending its decimals indefinitely. These numbers are most often used in mathematical analysis.

Let the number of additional days = x
With Rose's Moving, they would pay $40 for the first day plus $6 per additional day.
40 + 6x
With Riverside Rent-a-Truck, in comparison, the family would pay $90 for the first day plus $1 per additional day.
90 + x
Comparing both
40 + 6x = 90 + x
6x - x = 90 - 40
5x = 50
x = 50/5
x = 10
The number of additional days = 10 days
