Answer:
(srt(3)/2, -1/2)
Step-by-step explanation:
x = rcos theta
r = 1 on unit circle
x = 1 cos (-pi/6)
x = sqrt(3)/2
y = r sin theta
y =1 sin (-pi/6)=
y = -1/2

Answer:
The flip flops cost $25.56 after the discount and tax.
Step-by-step explanation:
A pair of flip flops is $30. This is our starting amount.
The tax will be applied on the price the flip flops are bought for. This means we must apply the discount first.
The discount is 20%. Let's find what the flip flops were sold for.
If the discount is 20%, the flip flops were sold for 80% of their original price. Let's find 80% of 30.
80% of 30 = ?
0.80 • 30 = ?
= 24
The flip flops were sold for $24.
Now we have to apply a 6.5% tax. To find the amount of money added to the total, we need to find 6.5% of 24.
6.5% of 24 = ?
0.065 • 24 = ?
= 1.56
The tax was $1.56.
We need to add the tax to the discounted price.
1.56 + 24 = ?
= 25.56
The flip flops cost $25.56 after the discount and tax.
Hope this helps!
