To find the answer for this question: 

x^2 + 8x 15/x - 4xx^2 - 16/2x + 6 

Apply the exponent rule: 
x^2 + 8x + 15/x - 4x^3 - 16/2x + 6 

Divide the numbers: 16/2 = 8: 
x^2 + 8x + 15/x - 4x^3 - 8/x + 6 

Apply the rule: a/c +/- b/c = a +/- b/c 
x^2 + 8x + 15-8/x - 4x^3 + 6 

After you subtract the numbers: 15 - 8 from the fraction that equals to 7: 
x^2 + 8x + 7/x - 4x^3 + 6 

So, your answer would be: x^2 + 8x + 7/x - 4x^3 + 6.

In Bangor it’s -3 F in Fairbanks it’s -12 F in Fargo it’s -8 F and in Calgary it’s -15 F in which city is to the coldest?
jonny [76]

Answer:

Calgary is the coldest

Step-by-step explanation:

The simple way to determine this will be to change the value of temperatures given in Fahrenheit to Celsius

32 F = 0°C

Formula to apply will be (T-32)×5/9 -------------where T is temperatures in Fahrenheit

Bangor is -3F-------------------change to Celsius

(-3-32)×5/9 =-35 × 5/9 = -19.44°C

Fairbanks is -12 ------------------------change to Celsius

(-12-32)×5/9 = -44 × 5/9 = -24.44°C

Fargo is -8 F ---------------------Change to Celsius

(-8-32)×5/9= -40×5/9 = -22.22°C

Calgary is -15 F-------------------------Change to Celsius

(-15-32)×5/9 = -47×5/9 = -26.11°C--------------coldest

What is the complex conjugate of 13-21i?
irga5000 [103]

Answer:

To find a complex conjugate, simply change the sign of the imaginary part (the part with the i). This means that it either goes from positive to negative or from negative to positive.

As a general rule, the complex conjugate of <span>a+bi</span> is <span>a−bi</span>.

Therefore, the complex conjugate of <span>3−2i</span> is <span>3+2i</span>.

Hope this helped!!... :D

Please correct me if I'm wrong!!.. :3
