Answer:
Step-by-step explanation:
To convert an equation into standard form, we want to get into the form .
If we have , our first step is to get the x term on the left side. We can do this by subtracting 3x from both sides.
I find it easier now to just divide both sides by -1, so that we have a more consistent equation.
Hope this helped!
Answer:
- number of multiplies is n!
- n=10, 3.6 ms
- n=15, 21.8 min
- n=20, 77.09 yr
- n=25, 4.9×10^8 yr
Step-by-step explanation:
Expansion of a 2×2 determinant requires 2 multiplications. Expansion of an n×n determinant multiplies each of the n elements of a row or column by its (n-1)×(n-1) cofactor determinant. Then the number of multiplies is ...
mpy[n] = n·mp[n-1]
mpy[2] = 2
So, ...
mpy[n] = n! . . . n ≥ 2
__
If each multiplication takes 1 nanosecond, then a 10×10 matrix requires ...
10! × 10^-9 s ≈ 0.0036288 s ≈ 0.004 s . . . for 10×10
Then the larger matrices take ...
n=15, 15! × 10^-9 ≈ 1307.67 s ≈ 21.8 min
n=20, 20! × 10^-9 ≈ 2.4329×10^9 s ≈ 77.09 years
n=25, 25! × 10^-9 ≈ 1.55112×10^16 s ≈ 4.915×10^8 years
_____
For the shorter time periods (less than 100 years), we use 365.25 days per year.
For the longer time periods (more than 400 years), we use 365.2425 days per year.
Answer:
c - 12 = 6; c = 18
Step-by-step explanation:
Just add 12 and 6.
Answer:
I think C 45 blocks are the right answer.
The polar coordinates of (-4, 150°) will be and 5069.09939523°
<h3>What is the coordinate about?</h3>
The formula for this conversion will be:
r =
θ =
=
the inverse of: is θ = 5069.09939523°
Therefore:
θ = 5069.09939523°
So the polar coordinates of (-4, 150°) will be and 5069.09939523°
