Which one of the points A(5.2). B(6,-3) and C(4.7) is the mid-point of the other two? Check your answer by calculating two distances.​

Answers

Answer:

A is the midpoint

Step-by-step explanation:

Given

A(5.2) B(6,-3) and C(4.7)

Required

Which is the midpoint

Midpoint is calculated using:

[tex](x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

Testing A as the midpoint, we have:

[tex](5,2) = \frac{1}{2}(6+4,-3+7)[/tex]

[tex](5,2) = \frac{1}{2}(10,4)[/tex]

[tex](5,2) = (\frac{1}{2}*10,\frac{1}{2}*4)[/tex]

[tex](5,2) = (5,2)[/tex]

The above equation is true. Hence, A is the midpoint of B and C

3. Explain why the polynomial 34 + 5x3 - 7x2 + 3x has a degree 3 and not 4.​

Answers

Answer:

See explanation below

Step-by-step explanation:

The degree of a polynomial is the LARGEST power at which the variable/s appear in their expression.

Notice that in the given polynomial, the highest power for the variable x is 3, from the term 5 x^3.

There is no other term with higher power for x.

The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .

We have to explain,  why the polynomial [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] has a degree 3 and not 4.

According to the question,

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

The degree of a polynomial is the largest power at which the variable appear in their expression.

[tex]Polynomial = 3^{4} + 5x^{3} + 7x^{2} + 3x[/tex]

The given polynomial, the highest power for the variable x is 3, from 5 .

Hence, The variable appear in the expression [tex]3^{4} + 5x^{3} + 7x^{2} + 3x[/tex] x which has highest power 3 not 4 .
