Answer:
d: 7, 38/6, -1.2, -3 1/4, -19/2.
Step-by-step explanation:
First, divide the fractions to get decimals, this is an easier approach to compare all the numbers.
-19/2 = -9.5
-3 1/4 = 4 x -3 = -12 + 1 = -3.25
38/6= 6.3333 (terminal 3)
The greatest numbers for this list is 6.33, -3.25, and -9.5. The rest of the numbers include -1.2 and 7.
With the entire order, we observe which lists are descending, starting with a positive or a negative number.
1. order can be: 7, 6.33, -1.2, -3.25, and -9.5 or 7, 38/6, -1.2, -3 1/4, -19/2.
2. order commonly confused can be: -9.5, -3.25, -1.2, 6.33, and 7 or -19/2, -3 1/4, -1.2, 38/6, 7.
The only order showing this is d: 7, 38/6, -1.2, -3 1/4, -19/2.
The reason why its not the second order starting with -19/2 is because descending typically refers to a positive number going down to a negative number. However, both orders can be right. For the sake of this problem, the best option is d.

What was the equation of the graph below before it was shifted to the right 1
unit?
GX)=(x-1.6)-(x-1.5)
A. G(x) = (x)3
B. G(x) = (x-0.5) ³ - (x -0.5)
C. G(x) = (x-2)³ - (x-2)
D. G(x) = (x-.5)³
The equation before the transformation is g(x) = (x - 0.6) - (x - 0.5)
How to describe the equation before the transformation?From the question, we have the following function that can be used in our computation:
g(x) = (x - 1.6) - (x - 1.5)
Also, we have:
Transformation = shifted to the right 1 unit
This means that
g(x) = f(x - 1)
So, we have
f(x) = g(x + 1)
Substitute the known values in the above equation, so, we have the following representation
g(x + 1) = (x - 1.6 + 1) - (x - 1.5 + 1)
Rewrite properly
g(x + 1) = (x - 0.6) - (x - 0.5)
So, the equation is g(x) = (x - 0.6) - (x - 0.5)

What is the difference in elevation in meters between point x and point y on the map?.
The difference in elevation in meters between the points X and Y is 360.
Why are there contour lines?
A contour line is a line drawn on a topographic map to represent a dip or elevation in the ground.
The vertical separation or difference in elevation between contour lines is referred to as a contour interval. Every fifth contour line is a set of bold or thicker lines known as an index contour.
Which 3 types of contour lines are there?
There are three different types of contour lines that you might find on a map: supplemental, index, and intermediate. Index lines are the thickest contour lines, and they are frequently numbered at a specific location along the line. You can see the elevation above sea level from this.
Point X is marked on the contour line of 1,600 m. Point Y is marked on the second contour line between the 1,200 m and 1,300 m contour lines, thus:
2 x 20 = 40
So we have 1,240 m. Having the elevations of the two points, we only need to take the lower value from the larger value:
1,600 - 1,240 = 360 m
So we get a result of 360 m of difference in elevation between the points X and Y.

a quadrilateral must be a parallelogram if one pair of opposite sides is congruent and parallel
A quadrilateral with two sets of opposing parallel sides is referred to as a parallelogram.To be a parallelogram, one pair of opposite sides must be congruent and parallel. Congruent means that two sides have the same measurements or length while parallel means that two lines never intersect. For example, if one pair of opposite sides is congruent and parallel, and the other pair of opposite sides is parallel, then the quadrilateral is a parallelogram. This is because the two pairs of opposite sides form parallel lines and the respective pairs have the same length. Therefore, the answer is c. congruent and parallel.

determine the probability of drawing either a queen or a heart? write your answer as a reduced fraction.
The probability that the card drawn is either a queen or a heart is 4/13
According to the given information
Consider the random experiment of picking one card from a deck of 52 cards that has been expertly shuffled, as well as the subsequent occurrences.
A queen is the card that was drawn.
H: the heart card was shown.
The chance that "the card drawn is a queen" is P(Q) = 4/52 = 1/13 because there are four queens.
The probability that the card selected will be a heart is P(H) = 13/52, or 1/4, because there are 13 hearts in the deck. Because the queen of hearts is one of the deck's cards, events Q and H are inclusive events. P(Q and H) = 1/52 is the likelihood that "the card picked is a queen and a heart (the queen of hearts)".
Four queens and thirteen hearts are included in the chance that "the card picked is a queen or a heart," but we do not want to count the queen of hearts twice. There are so 16 different methods to depict a queen.
The probability that the card drawn is either a queen or a heart
P(Q or H) = P(Q) + P(H) - P(Q and H)

The function that is gotten after transformation is; f(x - 1) = -2x - 4
How to Interpret the Graph Transformation?We are told that the parent function is f(x).
Now, after transformation, the function becomes;
f(x) = f(x - 1)
Now, the solid line graph has;
y-intercept = -2
x intercept = 1
Slope = -2/1 = -2
Thus, equation is;
f(x) = -2x - 2
Thus, for f(x - 1), what it means is that we will plug in (x - 1) for x in the parent function to get;
f'(x - 1) = -2(x - 1) - 2
= -2x -2 - 2

The equal gives the solution for the variable 'c' in the given equation. I.e., c = 2.6.
What is a solution for an equation?A solution is the only value that satisfies the equation. It is also said to be the root of the equation.
Calculation:The given equation is
5c = 13
To solve the equation, divide both sides of the equation by 5.
So, we get
5c/5 = 13/5
⇒ c = 13/5
On converting the fraction into a decimal, we get c = 2.6.
To find whether the solution is correct or wrong, just substitute the value into the equation. If we get L.H.S = R.H.S, then that solution is the valid or correct one.
Substituting the value in L.H.S of the given equation, we get
5c = 5(2.6)
On multiplying,
5c = 13.0 ≈ 13
⇒ L.H.S = R.H.S
Hence, the solution is valid. The value of c is 2.6.

a circle with a circumference of 396 cm is centered at the vertex of an angle, and the angle's rays subtend an arc that is 276.1 cm long. what is the measure of this angle in degrees?
1.1 cm is the 1/360th of the circumference. The circle's circumference is 69.72% of the arc that the angle's rays subtend.
We must comprehend and use the relationships between arc length and circumference in this question. By using geometry, we can determine that a circle's central angle is 360 degrees, and that the circle arc is directly proportional to the central angle.
The angle's rays' subtend an arc that is 69.72% the diameter of the circle.
The circumference's length is multiplied by 1/360 to get the 1/360th of the circumference, and the resulting measurement is
s= 1/360 x 396
= 1.1
the circumference is 1.1 cm.
By dividing the subtended arc by the arc length, one may determine the arc that the angle's subtend rays :

[C] 0.0106 or 1.06%
[D] 0.0863 or 8.63%
[E] 0.1108 or 11.08%
Keith's equivalent rate with simple compounding is 0.0998 or 9.98%.
The Correct option is (B).
What is Compound Interest?The yearly interest rate is raised to the number of compound periods minus one, and the starting principal amount is multiplied by both of these factors. The resulting value is subsequently deducted from the loan's entire original amount.
Given:
Keith is offered an interest rate of 8.27% for a loan.
Now, using the following formula:
r = ([tex]e^{(i/n)[/tex] - 1) x n
where r is the equivalent rate with simple compounding, i is the interest rate with continuous compounding, and n is the number of compounding periods per year.
We have, i = 8.27%
Also assume that the number of compounding periods per year is 12, since many loans are compounded monthly.
Then,
r = ([tex]e^{(0.0827/12[/tex]) - 1) x 12
= (1.0082 - 1) x 12
= 0.0082 x 12
= 0.0984 or 9.84%
