The solution of 20–(–48) is 68.

<u>Solution:</u>

To write the difference  20–(–48 ) as sum and simplify,

Multiplication of two negative sign becomes positive. When multiply a negative number by another negative number, the product becomes positive.  ⟹20 – (–48)= 20 + 48

Hence the difference 20 – (–48 ) can be written as sum  ( 20 + 48 ).

For simplification we add 20 and 48, 20 + 48 = 68.

If B is the standard basis of the space set of prime numbers P 3ℙ3 of​ polynomials, then let Bequals=​{1,t,t2​,t3​}. Use coordin
Alecsey [184]

Answer:

The set of polynomial is linearly independent

Explanations:

For clarity and easiness of expression, the complete solution is handwritten in the file attached. However, the following are the steps taken:

1) The coordinate vectors of the polynomials are formed as:

(1,0,6,-1), (0,1,02) and (1,1,6,0)

2) A matrix is formed using the coordinates of the polynomials as the columns of the matrix

3) The polynomial formed is row reduced to form an echelon matrix.

4) As seen from the reduced echelon form of the matrix, the rank of the matrix = 3

5) since the rank = number of polynomials = 3, the set of polynomials is linearly independent.

Two angles are complementary. One angle is labeled 2p+6°. The other angles is labeled 4p°. Find the value of p.
makkiz [27]

Answer:

<em>Value</em><em> </em><em>of</em><em> </em><em>p</em><em> </em><em>is</em><em> </em><em>14</em>

Step-by-step explanation:

given \: complementary \: angles \: add \: up \: to \: 90 \: degrees \\ then \\ 2p + 6 + 4p = 90 \\ 6p + 6 = 90 \\ 6(p + 1) = 90 \\ p + 1 =  \frac{90}{6}  \\ p + 1 = 15 \\ p = 15 - 1 \\ p = 14

Multiply. Write your answer as a fraction in lowest terms.
Step2247 [10]

Answer:

6 4/7

Step-by-step explanation:

Convert any whole numbers to mixed numbers

\frac{12}{1} \times \frac{23}{42}

Use fractions formula

\frac{a \times b}{c \times d} = \frac{e}{f}

\frac{12 \times 23}{1 \times 42} = \frac{276}{42}

Count how many times 276 goes into 42 <em>evenly</em>

<em></em>= 6\frac{4}{7}

Determine if the sequence is arithmetic. If it is, find the common difference.
mr_godi [17]

Answer:

In an arithmetic sequence, the difference between any two consecutive terms must always be the same number, which is known as the common difference.

So we just need to take different pairs of consecutive terms and see if their difference is always the same:

1) The differences are:

32 - 35 = -3

29 - 32 = -3

26 - 29 = -3

So yes, this is an arithmetic sequence and the common difference is -3

2) The differences are:

-23 - (-3) = -20

-43 - (-23) = -20

-63 - (-43) = -20

This is an arithmetic sequence, and the common difference is -20

3) The differences are:

-64 -(-34) = -30

-94 -(-64) = -30

-124 -(-94) = -30

This is an arithmetic sequence and the common difference is -30

4) The differences are:

-40 -(-30) = -10

-50 - (-40) = -10

-60 - (-50) = -10

This is an arithmetic sequence and the common difference is -10

5) The differences are:

-9 - (-7) = -2

-11 - (-9) = -2

-13 - (-11) = -2

This is an arithmetic sequence, and the common difference is -2

6) The differences are:

14 - 9 = 5

19 - 14 = 5

24 - 19 = 5

This is an arithmetic sequence, and the common difference is 5.

Which of the following equations is a constant function? y = x y = 5 x = 5
Mamont248 [21]

Answer:

Second Option

y = 5

Step-by-step explanation:

A constant function is one for which the range does not change regardless of the value of the domain.

f (x_1) = f (x_2) = f (x_3) = m

Where m is a constant.

The constant functions are horizontal lines parallel to the axis of the x

Note that

y = x is not a constant function because the value of y changes when x changes.

x = 1, y = 1

x = 2 y = 2

x = 5 is not a constant function because the range of the function is not constant. x = 5 is a vertical line

y = 5 is a constant function, since for any of the value of x, the value of y will always be 5
