Drag an expression to the box to create an equation with no solutions.
Anon25 [30]

Answer:

C

Step-by-step explanation:

4x + 3 = x + 3x + 5

4x + 3 = 4x + 5 //-4x on both sides

3 = 5 //Since the statement is false, it's no solution.

If, it had 3 = 3 or any number n = n, the solution would be infinite. But, if x is equal to any number n, x=n, it would have only one solution.

//Hope it helps

Find the product of z1 and z2, where z1 = 7(cos 40° + i sin 40°) and z2 = 6(cos 145° + i sin 145°).
Oduvanchick [21]
For two complex numbers z_1=re^{i\theta}=r(\cos\theta+i\sin\theta) and z_2=se^{i\varphi}=s(\cos\varphi+i\sin\varphi), the product is

z_1z_2=rse^{i(\theta+\varphi)}=rs(\cos(\theta+\varphi)+i\sin(\theta+\varphi))

That is, you multiply the moduli and add the arguments. You have z_1=7e^{i40^\circ} and z_2=6e^{i145^\circ}, so the product is

z_1z_2=7\times6(\cos(40^\circ+145^\circ)+i\sin(40^\circ+145^\circ)=42(\cos185^\circ+i\sin185^\circ)=42e^{i185^\circ}
