Answer:
7 %   $94.50(SALES TAX)   Question only asks for the SALES TAX THOUGH 
Step-by-step explanation:
$1350.00 x .07 =$94.50 
$94.50 is your sales tax on B 
$1444.50 (total) x 15% gratuity  is $1444.50 x .15 = $216.68
$1444.50 + $216.68 =$1661.18  
$1661.18 x .02 =$33.22 
$1661.18 + $33.22 = $1694.40 Total cost of your computer repair 
 
        
             
        
        
        
Answer:
Yes. Her solution is correct.
Step-by-step explanation:
Let's check if Jenna solution is correct:
To solve the equation 2x^2 +5x - 42 = 0, we can use Bhaskara's formula:
D = b^2 - 4ac = 25 + 4*2*42 = 25+336 = 361
sqrt(D) = 19
x1 = (-5 + 19)/4 = 14/4 = 7/2
x2 = (-5 - 19)/4 = -24/4 = -6
We must agree with Jenna's solution, because the values she found as solution are correct: with we replace these values of x in the equation, we will find 0 = 0, which is correct and proves that these values are the solution of the equation.
 
        
                    
             
        
        
        
R = 2 / (1 + sin <span>θ)
Using the following relations:
R = sqrt (x^2 + y^2)
sin </span>θ = y/R
<span>
R = 2 / (1 + y/R)
R</span>(1 + y/R<span>) = 2
</span><span>R + y = 2
R = 2 - y
sqrt(x^2 + y^2) = 2 - y
Squaring both sides:
x^2 + y^2 = (2 - y)^2
x^2 + y^2 = 4 - 4y + y^2
x^2 + 4y - 4 
</span>
        
             
        
        
        
Answer:
If the equation is 3^x=n (it isnt showing up properly)
Part A: any number greater than 1 will work. Say 2.
Part B: any number less than or equal to 1.
Step-by-step explanation:
If you set x=2, 3^2=9 9>3
If you set x=0, 3^0=1 1<3
