1) carl and four others bought identical shirts. the cost for all five shirts was $115 plus 8%
sales tax. if each person contributed $23, would that be enough to cover the bill?

1.18 more is needed.

Step-by-step explanation:

Each person puts in 23 dollars

1 person = 23$

5 people = 23 * 5 = 115

That pays for the shirts, it does not pay for the sales tax. So the answer is no. How much more do they need to put in?

8% * 115 = 8/100  * 115 = 9.20 dollars

9.2 / 5 = 1.84

Each person has to put in 1.84 dollars more to meet the full amount of the bill.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

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

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

a) 0

step-by-step explanation:

i^413 x i^0 = 0 as any number multiplied by a zero is
