Answer:
The most expensive item you can get is $23.44
Step-by-step explanation:
Because we are adding 8% in tax and 20% in tip, we know that overall we are spending 128% of the total dinner. So, we can divide the $30 we have to spend by 128% in order to find the original price of the item (don't forget to turn the percentage into a decimal first).
$30/1.28 = $23.44
Hello,
1)
z=√3-i
==>ρ²=3+1=4==>ρ=2
arctg(√3/-1)=-60°
z=2∠-60°=2(cos(-60°)+i sin(-60°))
w=-2-2i
==>ρ²=4+4=8==>ρ=2√2
arctg(-2/-2)=45°
w=2√2∠45°=2√2(cos(45°)+i sin(45°))
2)
z²=(√3-i)²=3+1-2√3*i=4-2√3*i
3)w^4=(2√2∠45°)^4=(2√2)^4 ∠180° =-64+0i
You may use radian but i like more degree.
The answer is 20.
If you think about it as 5/5 is 1 and one load is 1/5, you need 5 loads to get 1 ton. Then, you need another 3. To get this you do 5 X 3. So you need 15 loads to get 3. Then add 15 + 5 which then gives you 20
