Answer:

m=-12

Step-by-step explanation:

−5(3m+6)=−3(4m−2)

−15m−30=−2m+6

−15m−30+12m=−12m+6+12m

-3m-30=6

-3m-30+30=6+30

-3=36

-3/-3=30/-3

m=-12

A) The sixth term of an AP is twice the 3rd term and the first term is 3. Find the common

dangina [55]

Answer:

Step-by-step explanation:

The nth term of an AP is expressed as;

Tn = a+(n-1)d

a is the first term

n is the number of terms

d is the common difference

Sixth term

T6 = a+(6-1)d

T6 = a+5d

Third term;

T3 = a+(3-1)d

T3 = a+2d

If the sixth term of an AP is twice the 3rd term, then

a+5d = 2(a+2d)

a+5d = 2a+4d

Given a = 3

3+5d = 2(3)+4d

5d-4d = 6-3

d = 3

Common difference is 3

For the 10th term

T10 = a+9d

T10 = 3+9(3)

T10 = 3+27

T10 = 30

Hence the tenth term is 30

Find the product of z1 and z2, where z1 = 2(cos 80° + i sin 80°) and z2 = 9(cos 110° + i sin 110°)

nekit [7.7K]

ANSWER

$z_1 z_2=18( \cos( 190 \degree ) + i \sin( 190 \degree) )$

EXPLANATION

The given complex numbers are;

$z_1 = 2( \cos(80 \degree) + i \sin(80 \degree) )$

and

$z_2= 9( \cos(110 \degree) + i \sin(110 \degree) )$

Recall the binominal identity for complex numbers in polar form.

$z_1 z_2=r_1 r_2( \cos( \theta_1 +\theta_2) + i \sin(\theta_1 +\theta_2) )$

We apply this property to obtain,

$z_1 z_2=2 \times 9( \cos( 80 \degree + 110 \degree ) + i \sin(80 \degree + 110 \degree) )$

$z_1 z_2=18( \cos( 190 \degree ) + i \sin( 190 \degree) )$
