Answer:

The polar form of a complex number is another way to represent a complex number. The form z=a+bi is called the rectangular coordinate form of a complex number. The horizontal axis is the real axis and the vertical axis is the imaginary axis.

Answer:

  C, D

Step-by-step explanation:

This equation can be solved any of several ways. One that doesn't require much thought is using the quadratic formula.

For ax² +bx +c = 0, the solutions are ...

  [tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

In the given equation, a=2, b=11, c=5, so this becomes ...

  [tex]x=\dfrac{-11\pm\sqrt{11^2-4\cdot2\cdot5}}{2\cdot2}=\dfrac{-11\pm\sqrt{81}}{4}\\\\x=\dfrac{-11\pm9}{4}=\left\{-\dfrac{20}{4},-\dfrac{2}{4}\right\}=\{-5,-\frac{1}{2}\}[/tex]

The solutions are ...

  C. x = -5

  D. x = -1/2

My personal favorite is using a graphing calculator. The solutions are the x-intercepts of the expression on the left. That is, where its value is zero, as the equation says.

Answer:

20 m

Step-by-step explanation:

For the perimeter, add all the sides together:

4 + 6 + 3 + 5 + 2 = 20 m

Answer:

Step-by-step explanation: Perimeter of  figure is = sum of all sides

                                                                                    = 6m+3m+5m+2m+4m

                                                                                   = 9m+7m+4m

                                                                                    = 16m+4m

                                                                                    = 20m

Answer:84

Step-by-step explanation:

Since each trinagle's interior angles which is the angles in side the triangle always add up to 180 you could add the 2 given and then subtract by 180 so 48+48 which equals 96 then 180-96 which will give you 84 as x

Answer

48+48+x=180    x=84

Step-by-step explanation:

The sum of the 3 interior angles of a triangle is always the sum of 180 degrees.  

In short, this means that all three angles have to equal up to 180 degrees

48+48=96

180-96=84  x=84

To check your answer add

48+48+84 should equal 180. It does

Answer:

(-5,-3.5)

Step-by-step explanation:

Answer:

When you reflect a point across the x-axis, the x-coordinate remains the same, but the y-coordinate is transformed into its opposite (its sign is changed). If you forget the rules for reflections when graphing, simply fold your paper along the x-axis (the line of reflection) to see where the new figure will be located.

Step-by-step explanation:

Answer:

diagonal is 11.14 cm

Step-by-step explanation:

We start by writing the equation for the width (w) in terms of the length (L):

w = 2 L - 8

from the area = w * L = 62

we replace w in it:    w * L = (2 L -8) * L = 62

2 L^2 - 8 L = 62

2 L^2 - 8 L - 62 = 0

extract 2 common factor:

2 (L^2 - 4 L - 31) = 0

Using quadratic formula we get:

[tex]L=\frac{4+/-\sqrt{4^2-4(1)(-31)} }{2} \\L=\frac{4+/-\sqrt{140} }{2}\\L=7.916\\or\\L=-3.916[/tex]

So, we pick the positive answer L = 7.916 cm

Then we now know the with of the rectangle as well:

w = 2 * L - 8 = 2 * 7.916 - 8 = 7.832  cm

Now we estimate the diagonal of the rectangle using the Pythagorean theorem:

[tex]diag=\sqrt{7.916^2+7.832^2}\approx11.1356\,\,cm[/tex]

which rounded to two decimal places is 11.14 cm

Answer:

m = 7 and b = -12 therefore y = 7x - 12

Step-by-step explanation:

From the question we are given the first derivative of the function g to be 7, and it is known that the first derivative of a function is the slope, therefore the slope, m = 7.

Since we are looking for 'b' at x = 3 and we know that our slope is 7, we have:

g(3) = 7*3 + b. We are given g(3) = 9 so we have:

9 = 21 + b and b = -12.

Therefore, m = 7 and b = -12 and the equation of the line is y = 7x - 12.
