(WILL GIVE BRAINLIEST)Find the polynomial function with real coefficients that has zeros 1, 1 , 2+ i sqrt 3
neonofarm [45]

Answer:

x^3-x^2(4+i\sqrt{3} )+x(5+i2\sqrt{3} )-(2+i\sqrt{3} )=0

Step-by-step explanation:

We have given that this polynomial has the given zeroes of 1, 1, and 2+i\sqrt{3}, we can express the polynomial in a factored form where each zero has the form x-a (where a is our zero):

polynomial= (x-1) (x-1) (2+i\sqrt{3})

                  =(x^2+1-2x) (2+i\sqrt{3})

                   =x^3-x^2(4+i\sqrt{3} )+x(5+i2\sqrt{3} )-(2+i\sqrt{3} )=0

What is the value of x​
Sedbober [7]

Answer:

X = 56

Step-by-step explanation:

Subtracting 169 degrees from a straight line (180 degrees) gives you 11 degrees. with this information you can add 11 and 114 to get 124. Then you can subtract that amount from 180 (the measure of any triangle) and get your answer which is 56. I hope this helped!

Tia cut a 4-meter 8 centimeter wire into 10 equal pieces Marta cut a 540-centimeter wire into 9 equal pieces how much longer is
Artyom0805 [142]

Answer:

12 centimeters

Step-by-step explanation:

First lets separate both wires.

Tia's wire is 408 centimeters long. This is because 1 meter = 100 centimeters. This meter will be cut into 10 equal pieces. To do that, simply divide 408 by 10.

408 / 10 = 48 centimeter long pieces

Marta's wire is 540 centimeters long. This meter will be cut into 9 equal pieces. Like before, we will divide 540 by 9.

540 / 9 = 60 centimeter long pieces

To conclude, one of Marta's wires are 12 centimeters longer than Tia's.
