how do you write the quotient (9+i) over (9-i) in standard form? I need the answer but more importantly, I need to learn how to

solve these kinds of problems.

Since they are the conjugates of each (9-a and 9+a are conjugates, or with any number replacing 9) , we multiply it by (9+i)/(9+i) to get (9+i)^2/(9-i^2)=(81+2i+i^2)/(9-(-1))=(81-1+2i)/(10)=80/10+2i/10=8+i/5. Conjugates work because they make i into i^2 (-1) without any of the sneaky i's in the middle!

type the correct answer in the box. if the measure of angle θis 7⁢π6. the equivalent measurement in degrees is °.
Travka [436]

If the measure of an angle "θ" is 7⁢(π/6), then it's equivalent measurement in degrees is 210°.

As per question statement, we have an angle "θ" whose measurement in radians is 7⁢(π/6). We have to convert this radians into its equivalent measurement in degrees. Thus, to solve this question, we will have need to know the relation between radians and degrees, which goes as,

("π" Radian = 180°).

Then, we will apply unitary method to our provided data and use the above-mentioned relation to obtain our desired answer, i.e.,

π Radian = 180°,

then, 7π Radian = (180*7)°,

Then, 7⁢(π/6) Radian = \frac{(180*7)}{6} =(30*7)=210°.

  • Radian: This is an unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.
  • Degrees: This is another unit of measurement of angles, one unit of this being equal to one three-hundred-and-sixtieth of the circumference of a circle.

Steve just signed a lease to rent a new apartment. His monthly rent will be $800.00, and he will have to pay a one-time nonrefun
svp [43]

Answer:

800x+400=T

Step-by-step explanation:

800 is the monthly rent and x is the variable used to represent the number of months Steve will rent the apartment, and 400 is the security deposit that is half of 800. Lastly, when putting the equation together, the left side of the equation will equal to T.

Can someone solve this for me with their explanation please?
Lana71 [14]

First you want to subtract 36

so it looks like this \sqrt[4] {(4x+164)^3}=64

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

{(4x+164)^3}=64^4 which is equal to {(4x+164)^3}=16777216

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23
