Answer:
53, -84, 24, -38
Step-by-step explanation:
The scale factor changes by 1/8.
The numerator, 1 stays the same; the denominator changes. 16/2 = 8; it is 1/8 the scale of the previous scale.
Answer:
Step-by-step explanation:
We have the equation
with the initial condition
. It is not difficult to notice that this is a linear equation, which has the general expression
.
The solution of this equation is expressed by a general formula:
.
In the particular case of our equation, we have

.
Then, we must calculate the integrals
that implies
,
and

Then,
.
In order to obtain the value of the constant we substitute the initial condition
that implies 
Therefore,
.
