If I buy a sweatshirt for $30, and the sales tax is 7% in my state, how much will I pay for the sweatshirt, including the sales
algol13

Answer:

$32.10

Step-by-step explanation:

If you have sales tax, you would first convert the percentage to decimal, or 0.07. Then you would take this number, and add it to one before you multiply it by the price of the sweatshirt. This makes sure that you're not just calculating the sales tax, but the overall price of the shirt. So if you multiply:

30 x 1.07 = 32.1

Add the units, and you get $32.10

Hope this helps!

In the parallelogram above, BE= 7x-12, CE=10x-5, and DE= 3x+4. What is the length of BD​
kompoz [17]

ABCD is a parallelogram ⇒ BE = DE

So: 7x - 12 = 3x + 4

⇔ 7x - 3x = 4 + 12

⇔ 4x = 16

⇔ x = 16/4 = 4

⇒ BE = 7(4) - 12 = 28 - 12 = 16

⇒ DE = 3(4) + 4 = 12 + 4 = 16

⇒ BD = BE + DE = 16 + 16 = 32

Answer: BD = 32

Ok done. Thank to me :>

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) )
