Answer:
The answer is 600
Step-by-step explanation:
Because 60×10=600.
Answer:
y = 19 (3)x
Explanation:
y = abx
Plug in the numbers from the 2 given points to find a and b.
19 = ab0 = a
a = 19
171 = 19b2
b = 3
y = 19 (3)x
Answer:
Step-by-step explanation:
x^2+3y/xy
4^2+3*2/4*2
16+6/8
22/8
Answer:
Step-by-step explanation:
Remember that an IVP (initial value problem) of first order consists of solving a first-order differential equation (DE) and the solution 
must satisfy the <em>initial condition</em> 
. This means that the solution y(x) must pass through the point on the plane 
.
In this case, we know that 
is already a solution of the DE xy'+y=2x, the value of 
and we have to find the values 
for which the equality 
holds, that is, 
Multiplying by the above equation we obtain 
, where it follows by susbtracting 
that 
This is a <em>second-degree polynomial equation</em> and its solutions can be found by factoring: 
. Therefore, there are two possible values for : 7 and -1. From here we can see that -1 is the smaller and 7 is the larger.
Now, the larger interval 
for which is a solution of the IVP 
(the smaller value of ) is the maximal interval where y(x) is defined and pass through the point (-1,6). In this case, it must be that 
.
Finally, the larger interval 
for which is a solution of the IVP 
(the larger value of ) is the maximal interval where y(x) is defined and pass through the point (7,6). In this case, it must be that 
.
