Answer: $18.19

Step-by-step explanation:

The tax is applied after the discount so first find the discounted price:

= Price * ( 1 - discount rate)

= 20 * ( 1 - 15%)

= $17

The sales tax of 7% can then be applied:

= Price * ( 1 + tax rate)

= 17 * ( 1 + 7%)

= $18.19

Suppose you are a salesperson for
Sliva [168]

Answer:

27,000$ worth of sales

Step-by-step explanation:

What you need to earn - what you earn monthly = 1/6 of the amount you need to sell.

4000 - 2200 = 1800

1800 is ONE fifteenth of the sales.

1800 * 15 = 27,000.

You must sell MORE than $27,000 worth of sales in order to earn more than $4000.

The diagram shows a right-angled triangle.
Alexus [3.1K]

Step-by-step explanation:

there is no diagram so I'm just going to guess this however

sin x = 6/9

sin x = 2/3

sin x = 0.67

x = sin inverse of 0.67

x = 42.1

The graph below shows the function f(x)=x-3/x^2-2x-3 which statement is true
Ugo [173]

Answer:

The correct option is A.

Step-by-step explanation:

Domain:

The expression in the denominator is x^2-2x-3

x² - 2x-3 ≠0

-3 = +1 -4

(x²-2x+1)-4 ≠0

(x²-2x+1)=(x-1)²

(x-1)² - (2)² ≠0

∴a²-b² =(a-b)(a+b)

(x-1-2)(x-1+2) ≠0

(x-3)(x+1) ≠0

x≠3 for all x≠ -1

So there is a hole at x=3 and an asymptote at x= -1, so Option B is wrong

Asymptote:

x-3/x^2-2x-3

We know that denominator is equal to (x-3)(x+1)

x-3/(x-3)(x+1)

x-3 will be cancelled out by x-3

1/x+1

We have asymptote at x=-1 and hole at x=3, therefore the correct option is A....
