Answer:
$1.56
Step-by-step explanation:
125.32 : 80.5 = 1.55677 => ~1.56$
(a) The differential equation is separable, so we separate the variables and integrate:



When x = 0, we have y = 2, so we solve for the constant C :

Then the particular solution to the DE is

We can go on to solve explicitly for y in terms of x :

(b) The curves y = x² and y = 2x - x² intersect for

and the bounded region is the set

The area of this region is

Answer:
x=36
Divide the corresponding side (16) by 4/7
x+y=3
+ x-y=1
2x=4
x=2
x+y=3
2+y=3
-2. -2
y=1
(2,1)

Answer:
$342.37
Step-by-step explanation:
When a quantity is marked up by x%, its marked-up price is (1 +x/100) times its original price. Tax is effectively a markup.
Louise's costs are ...
$125 + (12.50 +19.50)(1.07) = $159.24
Louise priced her painting at ...
$159.24·(1 +1.15) = $342.37
