Answers
Answer:
The relation is reflexive as
(1,1),(2,2),(3,3)∈R
(2,1)∈R will not imply (1,2)∈R,
hence R is not symmetric
(2,1),(1,3)∈R doesn't imply (2,3)∈R, hence R is not transitive

Answers
Step-by-step explanation:
Given that Cooper answered 28 questions correctly and 7 incorrect answers, If the total number of questions is x,
let total number of questions be X,therefore X = 28+7

What are practical situations of geometric series.
Answers
Answer:
One of the practical situation of geometric series is : A ball bouncing is an example of a finite geometric sequence. Each time the ball bounces it’s height gets cut down by half. If the ball’s first height is 4 feet, the next time it bounces it’s highest bounce will be at 2 feet, then 1, then 6 inches and so on, until the ball stops bouncing
Answer:
Geometric series are seen in practical situations, most notably in those involving geometric growth or decay. If a series of numbers are formed by percentages, then it can result in a geometric sequence. Ex. compound interest (see below).
Step-by-step explanation:
A geometric series is the result of adding the terms of a geometric sequence. These sequences have a common ratio, r, which is used to find missing terms. The common ratio is found with [tex]r=\frac{a_n}{a_{n-1}}[/tex]. For example, [tex]a_1(r)=a_2, \mbox{ and } a_2(r)=a_3... \mbox{ etc.}[/tex]
Geometric sequences can be used to model practical situations, and such situation could involve geometric growth or decay.
A geometric sequence can be used to model compound interest. An example of this is [tex]A = P (1 + \frac{r}{100})^n[/tex] where the common ratio, r, of the series is equal to 1 + r/100 in the compound interest formula above.

Shula covered a box with fabric. The dimensions of the box are 7 inches x 11 inches and depth is 8 inches. If fabric costs 7 cents how much will she spend on fabric
Answers
Answer:
Option (D) is correct.
Shyla spend $30.94 on the fabrics
Step-by-step explanation:
Shyla has a box with the dimensions of 7 inches, 11 inches, 8 inches. Since it has 3 sides thus, it is form of a cuboid.
Here Length (l) = 7 inches
Breadth (b) = 11 inches
Height (h) = 8 inches
Surface area of Cuboid = 2( lb +bh + hl )
Substitute the values, we get,
Surface area of Cuboid = 2( 7 × 11 + 11× 8 + 7 × 8 )
= 2( 77 +88 +56)
= 422 square inches.
Given: the fabric costs 7 cents per square inch = $0.07 per square inches.
Money Shyla spend on the fabric = total area × cost of fabric per square inch
= 442 × 0.07
= $30.94
Thus, Shyla spend $30.94 on the fabrics.
So , Option (D) is correct.

"slope" means inclination. and as you can imagine, parallel lines must have the same inclination, or they would not be parallel.
so, the slope of D C must be also 2/7.

same thing as with 5.
both lines are parallel and must therefore have the same slope.
so, the slope of D C is also 3/4. and the first answer is correct.

Analyzing the information, it is clear that to find the solutions of the problems it is necessary to perform the calculation of mathematical arrangements.
What are arrangements?Correspond to a case of permutations, they are groupings that are formed with a number p of elements from a set of n elements. The elements of p must occupy ordered positions, where p ≤ n. The formula is:
A = n!/(n-p)!So, to solve the problems we do the following calculations:
A) 2^n =
2^8 = 256
B) We must pay attention to the statement, which asks for the minimum number of condiments required to prepare 1000 different sandwiches, so:
