Which of the following best describes the relationship between the chords NR and QS shown in the diagram below?
Answer:
C
Step-by-step explanation:
By observation, we can see very clearly that NR and QS are neither parallel nor perpendicular. Hence we can ignore A and B.
We notice that VT and VU are the same length.
Hence we can conclude that NR and QS must also be the same length (i.e they are congruent)
Therefore C is the answer.

On the other hand, Spain can produce 10 televisions in one week, while the United States and France produce only 5 and 4 televisions, respectively. has an absolute advantage in producing pillows, and has an absolute advantage in producing televisions.
Answer:
The correct answers is:
The United States has an absolute advantage in producing pillows, and Spain has an absolute advantage in producing televisions
Step-by-step explanation:
Absolute advantage is a term of economics which can be defined as an ability of a person, company or country to produce a greater quantity of goods as compared to his competetors.
We can surely understand that in the pillows market, the United States has an absolute advantage as it is producing about 50 pillows more than Spain and 100 pillows more than France in one week.
Similarly, in the televisions market, Spain has the absolute advantage because Spain is producing 5 more televisions than United States and 6 more televisions than France in one week

Dante is selling donuts outside a huge office building every morning. The first week
he made $25 selling donuts, the second week he made $45 the third week he made
$65! Everyone loved them and they are spreading the word. If this pattern continues
how much money will he be making in week 10?
Answer:
$205Step-by-step explanation:
45 - 25 = 20
65 - 45 = 20
as you can see the common difference between the 3 consecutive numbers 25 , 45 and 65 is a constant (20)
so ,we are in an arithmetic sequence case with :
first term 25 common difference r = 20Let’s label the sequence: Un
then
Un = U1 + (n-1)×r
= 25 + (n-1)×20
= 20n + 5
for n = 10 → U10 = 20(10) + 5 = 200 + 5 = 205

C. The graph of g(x) is the graph of f(x) shifted 6 units up.
D. The graph of g(x) is the graph of f(x) shifted to the right 6 units.
Answer:
B. The graph of g(x) is the graph of f(x) shifted to the left '6' units
Step-by-step explanation:
Type of transformation change to co-ordinate point
Vertical translation up 'd' units (x ,y) changes to (x , y+d)
Vertical translation down 'd' units (x ,y) changes to (x , y-d)
Horizontal translation left 'c' units (x ,y) changes to (x-c , y)
Horizontal translation Right 'c' units (x ,y) changes to (x+c , y)
Given f(x) translation left 'c' units f(x) changes to f(x-c)
Given f(x) translation right 'c' units f(x) changes to f(x+c)
Given Function f(x) = 10 ˣ
The given graph f(x) translation left '6' units
g(x) = f(x -6) = [tex]10^{x-6}[/tex]
Final answer:-
The graph of g(x) is the graph of f(x) shifted to the left '6' units
g(x) = f(x -6) = [tex]10^{x-6}[/tex]
Answer:
D. The graph of g(x) is the graph of f(x) shifted to the right 6 units.
Step-by-step explanation:
Use GeoGebra to graph those two function
f(x) = 10^x

The presence of an angle bisector will result in what type of angles?
Complementary angles
Congruent angles
Vertical angles
Supplementary angles
Answer:
Congruent angles
Step-by-step explanation:
Angle bisectors, divides the given angle into two equal parts
thus if value of angle is x then angle bisector will divide this angle into parts
of equal value x/2 .
_______________________
complementary angles are two angles whose sum is 90 degrees.
since we do not the value of angle we cannot say with certainty that the angles are complementary
Congruent angles are angles who have the same angular measurement.
since, in above problem we have seen that angle bisector divides the angle in two equal parts.
hence angles are equal and thus they are congruent angle.
Congruent angles is the correct answer.
_______________________________________
vertical angles are angle opposite two one another when two line cross each other.
Since in the problem line is not intersecting each other thus, angles do not qualify to be vertical angles
Supplementary angles are two angles whose sum is 180 degrees.
since we do not the value of angle we cannot say with certainty that the angles are Supplementary.
Hence correct option is Congruent angles
Answer:
congruent angles

Two sides of a parallelogram are in the ratio 5:4. If the perimeter is 54cm , the length of the larger side is -
9
11
12
15
Answer:
15 cm
Step-by-step explanation:
If we have two sides of a parallelogram in the ratio 5:4, then the other two sides must also be in the same ratio.
If the perimeter is 54, we can create the following equation regarding the length of each side
[tex]5x+4x+5x+4x=54\\\\18x=54\\\\x=3[/tex]
As our value for x is 3, and we know that the value for the larger side is 5x, we can simply plug in x to get the length of the larger side
[tex]5x\\\\5(3)\\\\15[/tex]

Which statement describes the graph of the function?
Answer:
The function has a hole when x = 0 and a vertical asymptote when x = 4.
Step-by-step explanation:
The function has a hole when x = 0 and a vertical asymptote when x=4. Therefore, option D is the correct answer.
The coordinates from the given table (-0.2, -0.238), (-0.1, -0.244), (0.1, -0.256), (0.2, -0.263), (3.7, -3.3) (3.8, -5), (3.9, -10), (3.99, -100) and (4.01, 100).
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
From the table, we have:
f(0) = undefined
f(4) = undefined
One of these values (the lesser value of x i.e. x = 0) is a hole, while the other is a vertical asymptote
Using the above as a guide, the correct statement is the function has a hole when x = 0 and a vertical asymptote when x = 4.
The function has a hole when x = 0 and a vertical asymptote when x=4. Therefore, option D is the correct answer.

Which of the following shows how the number 7 can be rewritten with the difference of squares identity? (16-9)=(4+3)(4-3) (18-11)=(9+6)(9-5) (25-4)=(5+2)(5-2) (16-9)=-1(4+3)(4-3) (64-1)=(8+1)(8-1)
Answer:
A) (16-9) =(4+3)(4-3)
Step-by-step explanation:
Explanation:-
Given the number = 7
The difference of two numbers are 16-9 =7
The difference of squares
4² - 3² = 7
We will use formula
a² - b² = (a-b) (a+b)
4² - 3² = (4 -3) (4+3)
16 -9 = (4 -3) (4+3)
Final answer:-
The number 7 can be rewritten with the difference of squares identity
16 -9 = (4 -3) (4+3)
Find the 7th term of the geometric sequence a3 =128,r=-1/4
Answer:
Step-by-step explanation:
The general formula for this sequence is a(n) = a(1)*(-1/4)^(n - 1). We don't yet know a(1).
If a(3) = 128, then 128 = a(1)*(-1/4)^(3 - 1), or
128 = a(1)*(1/16)
and so a(1) = 128/16
resulting in the specific formua a(n) = 8(-1/4)^(n - 1)
Now let's find a(7):
a(7) = 8(-1/4)^1 * (-1/4)^(6)
or
a(7) = 8(-1/4)^7
Which of the following conditions must be met in order to make a statistical inference about a population based on a sample
if the sample does not come from a normally distributed population?
mu >= 30
x >= 30
n>= 30
N>= 30
Answer:
For this case if we want to conclude that the sample does not come from a normally distributed population we need to satisfy the condition that the sample size would be large enough in order to use the central limit theoream and approximate the sample mean with the following distribution:
[tex] \bar X \sim (\mu, \frac{\sigma}{\sqrt{n}})[/tex]
For this case the condition required in order to consider a sample size large is that n>30, then the best solution would be:
n>= 30

Solve the equation using the Quadratic Formula:
x2 + 6x + 3 = 0
Answer:
x = -2[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
First we have to distinguish the numbers with x from the "normal" numbers.
2x and 6x are numbers with x.
3 and 0 are "normal" numbers.
Now we have to seperate them on different sides of the equal sign.
To do this, we can subtract 3 from the left side and then add it to 0 on the left side.
Therefore, the equation will now be 2x + 6x = -3.
Now we can add 2x and 6x together, making it 8x.
The equation will now be 8x = -3.
To find the product of x, we need to divide both sides together.
So 8 divided by -3 will make -2[tex]\frac{2}{3}[/tex].
Therefore, x is -2[tex]\frac{2}{3}[/tex].

Answer: 27 miles in 1 gallon
Step-by-step explanation:
297/11
The unit rate of 297 miles in 11 gallons will be 27 miles/gallons.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b, will be the denominator.
We will be used when division is not possible wholly
For example 4/2 is divisible so we write 2 instant of 4/2 while 1/3 is not divisible so we write 1/3 instant of 0.33.
Proportion is the relation of a variable with another. It could be direct or inverse.
The ratio is very useful to determine complex calculation where decimal number become tough to solve.
Given,
297 miles in 11 gallons
297 miles ⇔ 11 gallons
Divide by 11 on both sides
297/11 miles ⇔ 11/11 gallons
27 miles ⇔ 1 gallon
So, 27 miles in 1 gallon.
Hence unit rate is 27 miles/gallon will be correct.
