Help? 5/12 + 5/8 <br><br> (spam cause i need 20 characters)

Jobisdone [24]

Answer:

1 1/24

Step-by-step explanation:

5/12 + 5/8

We need a common denominator of 24

Convert the first number to have a denominator of 24

5/12 *2/2 = 10/24

Convert the second number to have a denominator of 24

5/8*3/3 = 15/24

Add the two converted numbers together

10/24 + 15/24

25/24

Change from an improper fraction to a mixed number

24/24 + 1/24

1 1/24

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

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

show me how to work this problem, point A(7,9)is dilated from the origin by scale factor r was= 6. what are the coordinates of p

frutty [35]

If the point is dilated from the origin by a scale factor of 6

Then the coordinates of point A becomes

A( 6x7 , 6x9)

$A_{0,6}(7,9)=(42,\text{ 54)}$
