From the following set of points, 26 is a trapezoid but not a isosceles trapezoid while 27 is not a trapezoid at all.
What is trapezoid?A closed, four-sided trapezoid in two dimensions has a perimeter and an area. Two of the sides are considered the bases of the trapezoid because they are parallel to one another.
The non-parallel sides of a trapezoid are referred to as its legs or lateral sides. The altitude is that distance between two parallel sides that is shortest. The area of a trapezoid can be easily calculated because the opposite sides are parallel to one another.
If the given points make an isosceles trapezoid then AB and CD must be equal and BC and AD must not be equal
Lets solve
26. AB = [tex]\sqrt{(-4-(-4))^2+(-1-6)^2}[/tex] = 7
CD = [tex]\sqrt{(2-(2))^2+ (6-(-4))^2}[/tex] = 10
BC = [tex]\sqrt{(-4-2)^2+ (6-6)^2}[/tex] = 6
AD = [tex]\sqrt{(-4-2)^2+ (-1-(-4))^2}[/tex] = 3√5
Thus, this not an isosceles trapezoid.
27. AB = [tex]\sqrt{(-5-2)^2+(2-6)^2}[/tex] = 8.06
CD = [tex]\sqrt{(-1-2)^2+ (6-1)^2}[/tex] = 5.83
BC = [tex]\sqrt{(-5-(-1))^2+ (6-6)^2}[/tex] = 6
AD = [tex]\sqrt{(2-(-5))^2+ (-1-2)^2}[/tex] = 3√5
None of the side make an trapezoid and it is not a isosceles trapezoid

Answers
Answer:
a(n) = 27*(2/3)^(n - 1)
Step-by-step explanation:
The first four terms are 27, 18, 12, 8.
Find the common ratio:
To do this, let that ratio = r, and write and solve 27r = 18. Thus, r = 2/3.
The general explicit formula for this sequence is
a(n) = a(1)*(2/3)^(n - 1), or, since a(1) = 27, a(n) = 27*(2/3)^(n - 1)
For the functions f(x) = 3x – 6 and g(x) = 3, (f9) (x) would be equal to:
a) (f9)(x) = 9x2 – 18
b) (f9) (2) = 9x – 18
c) (f9) (2) = x – 2
d) (f9) (x) = 3x – 3

Ok, so we need to do an advanced version of FOIL. We need to multiply -3x^2 by the other three numbers, then the same with 2. Then we add up like terms.
-3x^2 x -2x^3 = 6x^5
-3x^2 x -5x = 15x^3
-3x^2 x 4 = -12x^2
Now to do 2 x -----.
2 x -2x^3 = -4x^3
2 x -5x = -10x
2 x 4 = 8
Last, but not least, we combine like terms.
6x^5 + 11x^3 - 12x^2 - 10x + 8

Your job in a company is to fill quart size bottles of oil from a full 150- gallon oil tank. Then you are to pack 24 quarts of oil in a case to ship to a store. How many full cases of oil can you get from a full 150- gallon oil tank?
Answers
Answer:
25
Step-by-step explanation:
I gallon is 4 quarts so that would be a 600 quarts oil tank so since each case is 24 quarts 600/24 = 25
150 gallons of oil is equivalent to 600 quarts. A full 150-gallon oil tank can yield 25 full cases, with each case containing 24 quarts
The concept used to solve the problem is conversion:
The conversion factor that 1 gallon is equal to 4 quarts.
Given that,
Job: Fill quart-size bottles of oil from a full 150-gallon oil tank.
Packaging: Pack 24 quarts of oil in a case to ship to a store.
Tank Capacity: The oil tank is full and has a capacity of 150 gallons.
Convert the measurements to a common unit.
Since we have to fill quart-size bottles,
Convert 150 gallons to quarts.
Since 1 gallon is = 4 quarts,
So 150 gallons would be 150 x 4 = 600 quarts.
To determine how many full cases of oil we can pack from 600 quarts. Each case contains 24 quarts.
To find the number of cases,
Divide the total number of quarts by the number of quarts per case:
600 quarts ÷ 24 quarts/case
= 25 cases.
Therefore,
You can get 25 full cases of oil from a full 150-gallon oil tank.

Answer:
D : 10 feet
Step-by-step explanation:
Hello I think I can help with this.
Now how I would do this given a multiple choice question is kind of use brute force with your given answers to find the solution.
So the formula for area is known as (L x W x H)
or (length x width x height)
Lets see what we are given.
We are given the length which is 12
We are also given the width which is 4 1/2
And if we multiply these we can find the surface area of the base of this rectangular prism so lets do that.
12 multiplied by 4 1/2
=
54
Alright so now we know the base of this rectangular prism is 54 ft²
Now we can start the brute force method. So we are trying to find the height in this problem since we already have the width and length and have worked that out. So now all we do is multiply what we found (54) by the possible answers until one of them gives us the answer 540 ft³.
NOW this is actually really easy because we got 54 as our answer to length x width and our total amount of area is 540.
So instead of brute force we can take an easier route and do 540 / 54 and get an easy answer of 10 which is option D :
10 feet
I hope this helps you understand this a bit better!
If you are confused or have any concerns / questions feel free to comment or message me :)
Answer:
Height = 540/(4.5*12) = 10 feet

3. We know the x value which is -5 and the y value which is 1. We need to find the hypotenuse which we refer to the r. We use the pythagorean theorem for that
[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]
[tex] { - 5}^{2} + {1}^{2} = r {}^{2} [/tex]
[tex]25 + 1 = r {}^{2} [/tex]
[tex]26 = r {}^{2} [/tex]
[tex]r = \sqrt{26} [/tex]
Now let find the sin, csc, and tan.
To find sin let use the formula
[tex] \frac{y}{r} [/tex]
[tex] \frac{1}{ \sqrt{26} } [/tex]
Rationalize the denominator
[tex] \frac{1}{ \sqrt{26} } \times \frac{ \sqrt{26} }{ \sqrt{26} } = \frac{ \sqrt{26} }{26} [/tex]
[tex] \sin = \frac{ \sqrt{26} }{26} [/tex]
To find cosecant, it is the reciprocal of sin so it would be
[tex] \csc = \frac{26}{ \sqrt{26} } \times \frac{ \sqrt{26} }{ \sqrt{26} } = \sqrt{26} [/tex]
To find tan, do
[tex] \frac{y}{x} [/tex]
Which is simply
[tex] \tan= \frac{1}{ - 5} [/tex]

URGENT Q: A bicycle company produces y bicycles at a cost represented by the polynomial y² + 10y + 100,000. The revenue for y bicycles is represented by 2y^2 + 10y + 500. Find a polynomial that represents the company's profit. If the company only has enough materials to make 300 bicycles, should it make the bicycles?
Answers
Answer:
The company should not make 300 bicycles.
Step-by-step explanation:
Mathematically speaking, profit ([tex]P(y)[/tex]) equals the difference between revenue ([tex]R(y)[/tex]) and cost ([tex]C(y)[/tex]). That is:
[tex]P(y) = R(y) - C(y)[/tex] (1)
If we know that [tex]R(y) = 2\cdot y^{2}+10\cdot y + 500[/tex] and [tex]C(y) = y^{2}+10\cdot y+100000[/tex], then the profit function is:
[tex]P(y) = 2\cdot y^{2}+10\cdot y +500 -y^{2}-10\cdot y -100000[/tex]
[tex]P(y) = y^{2}-99500[/tex] (2)
The company can make the required amount of bicycles if and only if [tex]P(y) > 0[/tex]. If [tex]y = 300[/tex], then the profit of company is:
[tex]P(300) = 300^{2}-99500[/tex]
[tex]P(300) = -9500[/tex]
The company should not make 300 bicycles.

I know you're in RSM because I am too. If you need help, asking your teacher is better because they will explain it better.
The speed of the snail is 20 meter per hour
SpeedSpeed is the ratio of total distance travelled to total time taken. It is given by:
Speed = distance/ time
Let a represent the speed of the the turtle and b the speed of the snail. Hence:
b = a - 32 (1)
Also:
b = 52 / t
t = 52/b
a = 52 / (t + 1.6)
a(t + 1.6) = 52
t = (52 + 1.6a) / a
52/b = 52/a + 1.6
a = 52 meter per hour, b = 20 meter per hour
The speed of the snail is 20 meter per hour

Answer:
Step-by-step explanation:
7). Since, ∠4 and ∠5 are the linear pair of angles,
m∠4 + m∠5 = 180° [Supplementary angles]
72° + m∠5 = 180°
m∠5 = 180° - 72°
m∠5 = 108°
8). Since, ∠6 and ∠7 are the vertically opposite angles,
Therefore, ∠6 ≅ ∠7
m∠6 = m∠7
3x + 94 = 9x - 38
9x - 3x = 94 + 38
6x = 132
x = 22
m∠6 = 3(22) + 94 = 160°
m∠7 = 9(22) - 38 = 160°
9). Since, ∠2 and ∠3 are the linear pair of angles, both the angles will be supplementary.
m∠2 + m∠3 = 180°
(13x + 54) + (2x + 36) = 180°
15x + 90 = 180°
15x = 90
x = 6
m∠2 = 13(6) + 54 = 132°
m∠3 = 2(6) + 36 = 48°
