Which is the polynomial function of lowest degree with rational real coefficients, a leading coefficient of 3 and roots
V5 and 2?
Answer:
f(x) = [tex]3x^{3} - 6x^{2} - 15x + 30[/tex]
Step-by-step explanation:
If [tex]\sqrt{5}[/tex] is a root, then so is -[tex]\sqrt{5}[/tex]
f(x) = 3(x + [tex]\sqrt{5}[/tex])(x - [tex]\sqrt{5}[/tex])(x - 2)
= [tex]3(x^{2} - 5)(x - 2)[/tex]
= 3([tex]x^{3} - 2x^{2} - 5x + 10[/tex])
= [tex]3x^{3} - 6x^{2} - 15x + 30[/tex]

Volume formula is [tex]V = B \cdot h[/tex]
First find the area of the base (hexagon). The area of a hexagon can be found with the formula [tex]A = \frac{1}{2} P\cdot a[/tex] where [tex]a[/tex] is the apothem (line that's perpendicular to a side and connected to the center point) and [tex]P[/tex] is the perimeter.
We already know the length of the apothem (5.7 ft). We also have one side length already (6.58 ft), a hexagon has 6 sides, so [tex]P = 6\cdot 6.58 = 39.48[/tex] ft.
Plug these into the area formula
[tex]A = \frac{1}{2} (39.48)(5.7)[/tex]
Area of the base ([tex]B[/tex]) is 112.52 ft
Now plug into the volume formula using 15.4 ft as the height
Final answer:
[tex]V = 1732.81 ft^3[/tex]

A triangular prism is 19 yards long and has a triangular face with a base of 18 yards and a height of 12 yards. The other two sides of the triangle are each 15 yards. What is the surface area of the triangular prism?
Answer:
1128 Yard²
Step-by-step explanation:
From the question,
The surface area of a triangular prism is
A = bh+H(a+b+c)...................... Equation 1
Where a = First side of the triangular face, b = base of the triangular face, c = the other side of the triangular face, H = heigth of the prism, h = height of the triangular face
Given: a = 15 yard, b = 18 yards, c = 15 yards, h = 12 yards, H = 19 yards.
Substitute these values into equation 1
A = (18×12)+ 19(15+15+18)
A = 216+19(48)
A = 216+912
A = 1128 Yard²
Hence the surface area of the triangular prism is 1128 yard²

6, determine the length RT
Answer:RT=18
Step-by-step explanation: RS+ST=RT
6+12=RT
18=RT
The numeric length of RT is 16 units.
What is segment addition law?The segment addition postulate states that if we are given two points on a line segment, A and C, a third point B lies on the line segment AC if and only if the distances between the points meet the requirements of the equation AB + BC = AC.
Given that, Point S is on line segment RT. Given ST 5x-10 RT = 4x and
RS = 6,
Using segment addition law,
RT = RS + ST
4x = 6+5x-10
x = 4
Therefore, 4x = 16
Hence, The numeric length of RT is 16 units.

Answer:
1/3 of the 342 seats which would be 267 of the seats are used by the Students
Step-by-step explanation:
The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $6 and each adult ticket sells for $11. The auditorium can hold at most 100 people. The drama club must make no less than $770 from ticket sales to cover the show's costs. If xx represents the number of student tickets sold and yy represents the number of adult tickets sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
Im not really sure what the question is asking but the drama club could sell 70 adult tickes and 30 student tickes and they would make $950.
Step-by-step explanation:
Answer:
possible solution (10,80)
Step-by-step explanation:
Variable Definitions:
x=the number of student tickets sold
y= the number of adult tickets sold
“at most 100 people"→100 or fewer tickets
Therefore the total number of tickets sold, x+y, must be less than or equal to 100:
x+y≤100
“no less than $770"→$770 or more
Each student ticket sells for $6, so x student tickets will bring in 6x dollars. Each adult ticket sells for $11, so y adult tickets will bring in 11y dollars. Therefore, the total amount of revenue 6x+11y must be greater than or equal to $770:
6x+11y≥770
Solve each inequality for y:
x+y≤100
y≤−x+100
6x+11y≥770
11y≥770−6x
y≥ -6/11x+70
Graph y≤100−x by shading down and graph y≥-6/11x+70

Three erasers and five pencils cost $7.55. 6 erasers and 12 pencils cost $17.40. How much does 1 eraser cost? How much does 1 pencil cost?
Answer:
Step-by-step explanation:
erasers=e
pencils=p
3e+5p=7.55 ...(1)
6e+12p=17.40
divide by 2
3e+6p=8.70 ...(2)
(2)-(1) gives
p=8.70-7.55=1.15
from (1)
3e+5(1.15)=7.55
3e+5.75=7.55
3e=7.55-5.75
3e=1.80
e=1.80/3=0.60
cost of 1 eraser=$0.60
cost of 1 pencil =$1.15

Option D
Step-by-step explanation:
McKenzie wants to put the soil in a box with the soil height = (10 - 2) inches
(As she plans to keep 2 inches from the top of the box empty)
Length of the box = 8 inches
Width of the box = 12 inches
Since, soil in the box will get the dimensions same as of the box but the height will be 2 inches less than the box height.
Therefore, volume of the soil = Length × Width × height
V = 8 × 12 × (10 - 2)

Answer:
The angles of A and B are 45 degrees. This is true because the other angle is a right angle (90 degrees) and if you are making a triangle the degrees of the sides have to = 180 to be a complete triangle. The triangle is complete, so I took 180 – 90 = 90 ÷ 2 = 45.
The angle of C is 115 because it is a supplementary angle. A supplementary angle is an angle that has two angles with a sum of 180 degrees and 180 – 65 = 115

identify the graph of 2x^2 + 4xy + 4y^2 = 0 then find theta to the nearest degree.
Answer: 2x2 + 4xy + 4y2 = 0
2 xx + 4xy + 4yy = 0
...xx + 2xy + y*y + yy = 0
(x + y)^2 + yy = 0
if x is a constant
... 2yy + 4xy - 2xy + xx = 0
(2yy + 4xy + 2xx -2xx) - 2xy + xx = 0
2(y + x)^2 - 2xx - 2xy + xx = 0
2(y + x)^2 - xx - 2xy = 0
2(y + x)^2 - xx - 2xy +yy - yy = 0
(x + y)^2 + yy = 0
x = i*y - y
if x = r cos a
y = r sin a
cos a )^2 + cos a sina + sin a)^2 + sin a)^2 = 0

Mason is laying tiles on his entryway. The tiles are each 2/9 feet long, and the entryway is 7 1/2 feet long. How many tiles will Mason need to buy in order to cover the length of the entryway? Explain.
Answer:
1 2/3
Step-by-step explanation:
7 1/2x2/9
The required number of tiles will be 34 covering the length of the entryway.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
We have been given that the tiles are each 2/9 feet long, and the entryway is 7 1/2 feet long.
We have to determine the number of tiles will he need to buy in order to cover the length of the entryway.
According to the given question, the required solution would be as:
So the number of tiles covering the length of the entryway will be
⇒ 7 1/2 ÷ (2/9)
⇒ 15/2 ÷ (2/9)
⇒ 15/2 / (2/9)
Reciprocal the term in the denominator
⇒ (15/2) x (9/2)
Apply the multiplication operation,
⇒ 135/4
Apply the division operation,
⇒ 34
Thus, the required number of tiles will be 34 covering the length of the entryway.
