dimulka [17.4K]
We first add the tax to the non-food items.  We have ($3.00+$.50)*1.05=($3.50)*1.05=$3.675 (Which can be rounded up to $3.68, since we can't have a fraction of a cent).

Now, we add the cost of the food to $3.68.  As a result, we have $3.68+$2.50=$6.18 as the total bill.

What is the truth value for the following conditional statement?
Studentka2010 [4]

Answer:

TT→T

Step-by-step explanation:

If p is false, then ~p is true.

If q is false, then ~q is true.

Now note that

  • If a and b are both true, then a→b is true.
  • If a is true, b is false, then a→b is false.
  • If a is false, b is true, then a→b is true.
  • If a and b are both false, then a→b is true.

In your case, both~p and ~q are true, then ~p→~q is true too (or TT→T)

If `f(x)=x^2-81` and `g(x)=(x-9)^(-1)(x+9)`, find `g(x)xxf(x)`.
marshall27 [118]

<u>Answer:</u>

g ( x ) * f ( x ) = ( x + 9 ) ^ 2

<u>Step-by-step explanation:</u>

We are given the following two functions and we are to find g(x) * f(x):

f(x)=x2-81

g(x)=(x - 9)^{-1} ( x + 9)

g(x)*f(x)=x^{-81} * \frac{x+9}{x-9}

g ( x ) * f ( x ) =\frac{(x+9)(x-9)(x+9)}{x-9}

g ( x ) * f ( x ) = ( x + 9 ) ( x + 9 )

g ( x ) * f ( x ) =( x + 9 ) ^ 2
