Han is multiplying 10x^4 by 5x^3 and gets 5x^7. He says that 0.5x^3 is not a polynomial because 0.5 is not an integer. What is the error in Han’s thinking? Explain your reasoning.

Answers

The result of the product with [tex]5x^7[/tex], we can see that Han neglected the zero taking 50 the same as 5 which is wrong

Given the polynomial functions

r(x) = [tex]10x^4[/tex]

t(x) = [tex]5x^3[/tex]

Taking the product of both functions:

P(x) = r(x) * t(x)

P(x)= [tex]10x^4\times 5x^3[/tex]

P(x) = [tex](10\times 5) \times(x^4\times x^3) = 50x^7[/tex]

Comparing the result of the product with [tex]5x^7[/tex], we can see that Han neglected the zero taking 50 the same as 5 which is wrong.

Which matrix multiplication is defined ?

Answers

Answer:

A. CB

Step-by-step explanation:

3 x 2 (C is a 3 by 2) matrix can be multiplied to a 2 x 2 (B is a 2 by 2) matrix since C has 2 columns that are equal to the number of rows in the second matrix B.

A way of checking if two matrices can be multiplied is to first check the number of columns the first matrix contains and then check the number of rows that the second matrix contains.

If the number of columns in the first matrix equal the number of rows in the second matrix then that means it is possible to multiply these matrices.

Answer:

$22.45 per month

Step-by-step explanation:

Fred's family will pay for cell service for 5 phones at a regular monthly rate of c dollars for each phone. They will also receive a discount of $50. The first month's payment will be $62.25. This equation represents the situation.

−

62.25

monthly cost of cell service for 5 phones

one-time discount

first month's payment

Now, solve the equation for c.

5c–50

= 62.25

= 112.25 Add 50 to both sides

= 22.45 Divide both sides by 5

The regular monthly rate for each phone is $22.45.

Which of these represents the conjugate of the impedance of a circuit written as 7 – i ohms?

A
–7 – i ohms

B
–7 + i ohms

C
–7i ohms

D
7 + i ohms

Answers

For the expression 7 - i ohms, the conjugate will be 7 + i ohms (the sign was changed from negative to positive)

The impedance of the circuit is written in form of a complex number.

The standard representation of a complex number is expressed as a + ib where:

a is the real part

ib is the imaginary part

The conjugate of the complex number a + ib will be a - ib. Note that the signs of the expression were changed from addition to subtraction.

Similarly for the expression 7 - i ohms, the conjugate will be 7 + iohms (the sign was chaged from negative to positive)

Find the measure of the angles (S)

Please help out:/

Answers

Answer:

Step-by-step explanation:

The triangle’s angles add up to 180°

so 180 - (5x - 2) = the another one interior angle

180 - 5x + 2

182 - 5x

and then 2x + 76 + (182 - 5x) = 180

2x + 76 + 182 - 5x = 180

258 - 3x = 180

78 = 3x

x = 26

so 2x = (26)(2) = 52

5x - 2 = (5)(26) - 2 = 128
