X-15=3 so first thing to do is to isolate the x. To do this, you do the following:
x-15=3
+15+15
------------
x= 18
18-15=3
Answer:
The general solution of the given differential equation
Step-by-step explanation:
Step(I):-
Given differential equation
y⁴+18y"+81y=0
⇒ (D⁴+18D²+81)y =0
The auxiliary equation
we will use formula ( a + b)² = a² + 2 a b + b²
⇒ ( m² + 9 ) ² = 0
⇒ ( m² + 9 ) ( m² + 9 ) = 0
m² + 9 = 0
The complex roots are 0± 3 i ,0 ± 3 i
<em>Step(ii)</em>:-
The complementary function
The general solution of the given differential equation
The general solution of the given differential equation
Answer:
$93.15 will be the cost of the sport coat.
Step-by-step explanation:
Given that
Price of a sport coat = $230
Sale on all sport coats = 55%
So, discount sport coat as per sale:
So, discounted price offered to the customer = $230 - $126.5 = $103.5
It is given that the customer has an coupon of additional discount of 10% off:
So, he will have an additional discount of :
$103.5 10
So, final cost for the customer of the product with price $230:
$103.5 - $10.35 =<em> $93.15</em>
Start off by finding 18% of 13.90.
18%=18/100=0.18
0.18(13.9)=2.5
An 18% tip would be $2.50.
Now, to find out if Lana has enough money, add $2.50 to $13.90 to find out the total amount she would leave. You get $16.40. Since $16.40>$15, the answer is no because the total cost including the 18% tip is greater than $15.
