Sage needs 2 boards to make a shelf. One board is 260 cm long and the other is 1 1/4 m long. What is the total length of the shelf?

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)

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.

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.

Answer:

After 460 calls plan 1 is more economical than plan 2

Step-by-step explanation:

Plan 1: 36x + 0y

Plan 2: 13x + 0.05y

36x < 13x + 0.05y

36x - 13x < 0.05y

23x < 0.05y

23/0.05x < y

460x < y

Answer:

Step-by-step explanation:

6) y = 2x² +  6x - 80

1) y = 2*x² + 2*3x - 2*40

  y = 2 [ x² + 3x - 40]

2) Sum = 3

Product = -40

Factors = (-5) ; 8   {-5 +8 = 3  ; (-5)*8 = -40}

y = 2 [ x² + 8x - 5x - 40]

      = 2 [ x(x + 8) -  5(x + 8) ]

      = 2 [ (x +8) (x - 5)]

y = 2(x +8)(x -5)

b) y = 0

2(x + 8)(X - 5) = 0

x + 8 = 0 ;  x - 5 = 0

x = -8 ;             x = 5

(-8) ; 5  are the zeros.

13) 29.75

14) P : P

Step-by-step explanation:

13)

4 ------ 17

7 ------ x

4x = 7*17

4x = 119

x = 29.75

14) A square is a square it has all sides the same, so p : p is the ratio

The correct answer: 01:12 A.M. OR 13:12 P.M.

First, decompose 30, 18 + 12 = 30.

Since 12:42 Minutes + 18 Minutes

is equal to 13:00, then add the remaining 12 Minutes, completing a total of 01:12 a.m. OR 13:12 P.M.

And y = 7?

Step-by-step explanation:

Answer:

Step-by-step explanation:

You have 2 points given. Take them seriously. They represent actual numbers that don't need to be rounded.

The two points are (2,-2) and (-3,-6)

Now construct a line in point intercept form from these two points.

m = (y2 - y1)/(x2 - x1)

m = (-2 - - 6)/(2 - - 3)

m = 4/5

So far what you know is

y = 0.8 x + b

Use either one of the two points to get b (the y intercept)

x = 2

y = - 2

-2 = 0.8*2 + b

-2 = 1.6 + b             Subtract 1.6 from both sides

-3.6 = b

y = 0.8x - 3.6

The outcome variable is also called the response or dependent variable, and the risk factors and confounders are called the predictors, or explanatory or independent variables. In regression analysis, the dependent variable is denoted "Y" and the independent variables are denoted by "X".
