Consider matrices A, B, and C.

Which matrix represents (A-B)-C?

Answers

Answer:

B.) I cant insert a 2x2 matric but the [5 7

7 4] matrix is correct

Step-by-step explanation:

I got a 5/5 on the test so I know that B is the correct answer

The matrix which represents (A-B)-C will be the matrix in option (B).

What is the matrix?

matrix, a collection of numbers lined up in rows and columns to produce a rectangular array. The elements of the matrix, also known as the entry, are the numerals.

In another word, a matrix is a set of variables that are arranged in such a good way that we can create algebraic equation from that.

In computer graphics, where they have been used to describe picture transformations and other alterations, matrices have vital applications as well in many sectors.

Given that the matrix

A - B = [first raw 3 ,1 in second raw 2 ,0]

Now (A - B) - C = [ first raw 5 ,7 in second raw 7 , 4]

Hence, the correct option is (B).

A geometric series is a series in which the division of any consecutive two terms will be the same.

here, we have,

to determine the situation:

The given parameters are:

Initial = 5200

Rate = 5%

Because the population by 5% every year, then the situation is a geometric sequence.

The common ratio is then calculated as:

Ratio = 1 + Rate

This gives

Ratio = 1 + 5%

Evaluate

Ratio = 1.05

Hence, the situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.

ben is right, you must add 25 not subtract it

Answer:

BMX Ben is correct and Pizza Pete is wrong

Step-by-step explanation:

For Both equations, we must isolate the x, or move everything to one side. So you'd have to add 25 because you have a negative 25 and a negative number plus a positive version of itself equals 0

x-25=7

+25=25

__________

x=32

The second one is incorrect because you are subtracting negative 25 from a 25, which is -50

D
F
Note: Figure is not drawn to scale.
O 3 feet
O 10 feet
O 141 feet
O 21 feet

Answers

Answer:

21 feet

Explanation:

Using pythagorean theorem to find the length of the added length of the bottom.

A^2+B^2=C^2 or 4^2+B^2=5^2 or 16+B^2=25

25-16=9 so B^2 is 9 and the square root of that is 3 so B is 3. Then you add 15+3+3 to get 21.

Ethan sold 2/3 gallon of lemonade. Kayla sold some lemonade too. Together, they sold 1 1/4 gallons. Who sold more lemonade, Ethan or Kayla? How much more ?

Answers

Rewrite 1 1/4 as an improper fraction:

1 1/4 = 5/4 gallons.

Rewrite both fractions with a common denominator:

2/3 = 8/12

5/4 = 15/12

Subtract the amount Ethan sold from total:

15/12 - 8/12 = 7/12

Kayla sold 7/12

This means Ethan sold more, because 8/12 is more than 7/12
