Sonya walks on a treadmill at a constant rate of 3.5 miles per hour. A graph showing the relationship between the time she walks and the distance she travels passes through the origin and the point (1, 3.5) Name three other points that lie on the graph of the line.
Answer:
7, 10.5, 14
because you have to keep adding 3.5 like from 3.5 you add another 3.5 to get the 7.
Find the determinant of the following matrix. A =
-2 6
3 5
Answer:
[tex]|A| = - 28[/tex]
Step-by-step explanation:
Given
[tex]A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right][/tex]
Required
Determine the determinant
For a two by two matrix, A such that:
[tex]A = \left[\begin{array}{cc}a&b\\c&d\end{array}\right][/tex]
The determinant |A| is:
[tex]|A| = a * d - b * c[/tex]
So, in
[tex]A = \left[\begin{array}{cc}-2&6\\3&5\end{array}\right][/tex]
The determinant is:
[tex]|A| = -2 * 5 - 6 * 3[/tex]
[tex]|A| = -10 - 18[/tex]
[tex]|A| = - 28[/tex]
Suppose that U is an infinite universal set, and A and B are infinite subsets of U . Answer the following questions with a brief explanation. Must A c be finite? Must A ∪ B be infinite? Must A ∩ B be infinite?
Answer:
A c must not be finite.
A ∪ B must be infinite.
A ∩ B must not be infinite.
Step-by-step explanation:
Must A c be finite?
Suppose
U = {....-4,-3,-2,-1,0,1,2,3,4.......}
A = {....-4,-2,0,2,4.......} which is infinite set
B = {....-3,-1,0,1,3.......} which is also infinite set
So We need to calculate the A compliment
[tex]A^{c}[/tex] = U - A = {....-4,-3,-2,-1,0,1,2,3,4.......} - {....-4,-2,0,2,4.......} = {....-3,-1,0,1,3.......}
Hence [tex]A^{c}[/tex] is also an infinite set.
The statement "Must A c be finite?" is incorrect.
Must A ∪ B be infinite?
In AUB all the elements of set A and set B are combined into a single set to get the union of A and B. If A and B are the infinite set then their union must also be an infinite set because all the elements of infinite sets will be there so the union of these infinite sets will also be an infinite set.
The Statement "Must A ∪ B be infinite?" is correct.
Must A ∩ B be infinite?
In A∩B the common elements of both sets will be the answer to the intersection of A and B set. If we consider the A and B are the infinite subsets of a Universal set that carry all the elements then there will not be any common element in both sets A and B.
The Answer of A∩B is { } or empty set.
The statement "Must A ∩ B be infinite? " is incorrect.

You created a blog and after 2 weeks you get your first subscriber. The number of subscribers grows quickly, quadrupling each week afterwards.
Excited about your blog's popularity you wonder, how many subscribers will the blog have 12 weeks after you create it?
Answer:
1 x 4 x 12 = 48
Step-by-step explanation:
48 subs
The number of subscribers at 12 weeks is required.
Number of subscribers at 12 weeks would be 1048576.
a = Initial subscriber count at 2 weeks = 1
Week at which number of subscribers is required is 12.
x = Duration between the weeks = [tex]12-2=10[/tex]
r = Rate of increase = 4
The required formula is
[tex]f(x)=ar^x\\\Rightarrow f(10)=1(4)^{10}\\\Rightarrow f(10)=1048576[/tex]
Number of subscribers at 12 weeks would be 1048576.

You are building a door frame. The two sides are parallel and the top and bottom are also parallel. Which additional statement does not give enough information to conclude that the door frame forms a rectangle?
Answer:
"The diagonals of the door frame are congruent."
Step-by-step explanation:
The statement that would not give enough information would be "The diagonals of the door frame are congruent." This is because a rectangle does have congruent diagonals but a rhomboid also has congruent angles and has opposing parallel sides. Therefore, this statement does not give sufficient information to prove that the object in question is a rectangle. We would need more information such as the length of the sides or the degree of the angles.

Compute the sample variance for the following scores: 25, 36, 41, 28, 29, 32, 39, 37, 34, 34, 37, 35, 30, 36, 31, 31
Answer:
Step-by-step explanation:
From the given information:
The mean [tex]\hat x = \dfrac{\sum x}{n}[/tex]
[tex]\hat x = \dfrac{25+36+41+28+29+32+29+37+34+34+37+35+30+36+31+31}{16}[/tex]
[tex]\overline{x} = \dfrac{535}{16}[/tex]
[tex]\overline{x} = 33.44[/tex]
The sample variance is as follows:
[tex]S^2 = \dfrac{\sum dx^2 - ( \dfrac{\sum dx)^2}{n} )}{n-1}[/tex]
[tex]S^2 = \dfrac{279- ( \dfrac{7}{15} )^2}{15}[/tex]

Factor out the GCF of 18x3y4+24x2y5
(A) 6x3y5(7)
(B) 6(3x3y4+4x2y5)
(C) 6x2y4(3x+4y)
(D) 42x5y9
Answer:
c
Step-by-step explanation:
18x³y⁴ = 2 * 3 * 3 * x³ * y⁴
24x²y⁵ = 2 * 2 * 2 * 3 * x² * y⁵
GCF = 2 * 3 * x² * y⁴ = 6x²y⁴
18x³y⁴ + 24x²y⁵ = 6x²y⁴(3x + 4y)

8 + __ = 4(2+4) I need help on this also can you explain it to me so I know next time
Answer:
16.
Step-by-step explanation:
We need 8 + a number to equal 24. We need it to equal 24 because 2 + 4 = 6 and 6 x 4 = 24. To find the missing number we need to subtract 8 from 24. 24 - 8 = 16. Let's plug 16 into the equation.
8 + 16 = 4(2 + 4)
24 = 4(2 + 4)
24 = 4(6)
24 = 24
Therefore, 16 is the correct answer.
A group is diving at an depth of 20 feet. If they rise 20 feet, their new elevation will.
A. end up at exactly 0 feet of elevation.
B. result in a positive elevation.
C. result in a negative elevation.
D. be less than it was before.
Answer:
A. end up at exactly 0 feet of elevation.
Step-by-step explanation:
This is because, at a depth of 20 feet, their position is -20 feet below the water surface. If they rise by 20 feet, we add 20 feet to their current position to reach their new position.
So, -20 feet + 20 feet = 0 feet.
So, their new elevation will end up at exactly 0 feet of elevation.
In his Fourteen Points, why did President Wilson include resolutions specifically about European
territories?
A Wilson insisted that Germany should take public responsibility for starting the war that had
destroyed many territories.
B The Treaty of Versailles did not include any detailed restrictions on territorial boundaries
C Territorial disputes among European nations were a major reason the war began in the first
place
D There was a strong international push for freedom of the seas and the reduction of armaments
Answer:
The correct answer is C. President Wilson included resolutions specifically about European territories in his Fourteen Points because territorial disputes among European nations were a major reason the war began in the first place.
Step-by-step explanation:
The Fourteen Points were the pacifist plan devised by President Woodrow Wilson at the end of World War I, with the aim of avoiding tensions between the former European combatants of the conflict and thus achieve a lasting peace between nations, framed in the League of Nations as supranational entity. Basically, the Fourteen Points sought to avoid the imposition of excessive sanctions on the defeated, as well as the obtaining of great benefits by the winners, so as not to break the territorial status quo prior to the war and thus avoid generating tensions in the future.
Answer:
C.) Territorial disputes among European nations were a major reason the war began in the first place.

Answer:
1. B. <1 and <2
2. C. 37°
3. B. 40°
Step-by-step explanation:
1. Complementary angles add up to 90°.
From the diagram given, <1 and <2 are complementary because they sum up to 90°.
The answer is B. <1 and <2
2. Given that,
m<1 = 37°, m<4 = 37° also.
This is because m<1 and m<4 are Vertical angles. Vertical angles pair are equal.
The answer is: C. 37°
3. If m<1 = 50°, then:
m<5 = 90 - m<4
m<1 = m<4 = 50° (vertical angles)
m<5 = 90 - 50 (substitution)
m<5 = 40°
Answer is B. 40°
