Answer:

Step-by-step explanation:
The general solution will be the sum of the complementary solution and the particular solution:

In order to find the complementary solution you need to solve:

Using the characteristic equation, we may have three cases:
Real roots:

Repeated roots:

Complex roots:

Hence:

Solving for
:

Since we got complex roots, the complementary solution will be given by:

Now using undetermined coefficients, the particular solution is of the form:

Note:
was multiplied by x to account for
and
in the complementary solution.
Find the second derivative of
in order to find the constants
and
:

Substitute the particular solution into the differential equation:

Simplifying:

Equate the coefficients of
and
on both sides of the equation:

So:

Substitute the value of the constants into the particular equation:

Therefore, the general solution is:


It was 4.2 because 1/5 equals to .2
(x+2)(x+8) = x^2 +10x +16
(x^2 + 10x + 16)(x-1) = x^3+9x^2+6x-16, so the other dimension is x-1
What we need to know is how much is 1/3 of 25 2/5.
We will be multiplying fraction by a fraction and for this, it's good to change mixed numbers into improper fractions:
25 2/5=

and now we multiply it by 1/3:

and that's the answer: the basketball equipment weights 7 4/5 pounds.
Answer:
Step-by-step explanation:
<u>Solve the inequality:</u>
- - a + 1/3 > 1/4
- a < 1/3 - 1/4
- a < 4/12 - 3/12
- a < 1/12
Correct choice is B
