Answer:
A, B, D
Step-by-step explanation:
The "opposite" of a number is that number with its sign changed.
__
- The opposite of zero is zero.
- A number and its opposite are located the same distance from zero on a number line.
- The opposite of a negative number is always a positive number.
None of these are equivalent to 34; they're all different values.
Answer:
2 1.2 and -2 1/2
Step-by-step explanation:
<u>(83.9 × 10^12)(2.87 × 10^-³)</u>
3.76 × 10²
<u>(83,900,000,000,000)(0.00287)</u>
376
<u>240,793,000,000</u>

640,406,914.9
Let

Differentiating twice gives


When x = 0, we observe that y(0) = a₀ and y'(0) = a₁ can act as initial conditions.
Substitute these into the given differential equation:


Then the coefficients in the power series solution are governed by the recurrence relation,

Since the n-th coefficient depends on the (n - 2)-th coefficient, we split n into two cases.
• If n is even, then n = 2k for some integer k ≥ 0. Then




It should be easy enough to see that

• If n is odd, then n = 2k + 1 for some k ≥ 0. Then




so that

So, the overall series solution is
