Question 1 of 5

melisa1 [442]

If one solution is -3-5i then the other solution will be -3+5i

So, Option A is correct.

Step-by-step explanation:

We need to find the other solution of the quadratic function, when one solution is -3-5i

The quadratic equation is of the form: $ax^2+bx+c$

The complex roots of the quadratic equation are of form: $a\pm bi$

So, if one solution is -3-5i then the other solution will be -3+5i

So, Option A is correct.

Solve for m 1/C+1/m=1/z

9966 [12]

Answer: " m = zC / (C − z) " .
___________________________________
Explanation:
_________________________
Given: 1/C + 1/m = 1/z ; Solve for "m".

Subtract "1/C" from each side of the equation:
____________________________________
1/C + 1/m − 1/C = 1/z − 1/C ;

to get: 1/m = 1/z − 1/C ;
____________________________________
Now, multiply the ENTIRE EQUATION (both sides); by "(mzC"); to get ride of the fractions:
_________________

mzC {1/m = 1/z − 1/C} ;

to get: zC = mC − mz ;

Factor out an "m" on the "right-hand side" of the equation:

zC = m(C − z) ; Divide EACH side of the equation by "(C − z)" ; to isolate "m" on one side of the equation;

zC / (C − z) = m(C − z) / m ; to get: 24/8 = 3 24

zC/ (C − z) = m ; ↔ m = zC/ (C − z) .

A plane travels at a speed of 205mph in still air. Flying with a tailwind, the plane is clocked over a distance of 975 miles. Fl

irakobra [83]

Answer:

T1 = 975 / (205 + V) flying with wind

T2 = 975 / (205 - V) flying against wind

T2 = T1 + 2

975 * {1 / (205 - V) - 1 / (205 + V)] = 2

(205 + V + V -205) / (205^2 - V^2) = 2 / 975

V^2 + 975 V - 42025 = 0 rearranging

V = 41.3

Values of flying are 246.3 and 163.7

Check:

T1 = 975 / 246.3 = 3.96 hrs

T2 = 975 / 163.7 = 5.96 hrs
