Last one? I’m not sure but that’s what I would put
To multiply these, we use the FOIL method (first, outside, inside, last). Also, 1√2 is equivalent to √2. It's just like saying 1x is the same x.
Multiplying the first values will give you:
√2 * √6 = √12 = √4*3 = √2*2*3 = 2√3
Multiplying the outside values will give you:
√2 * -√10 = -√20 = -√4*5 = -√2*2*5 = -2√5
Multiplying the inside values will give you:
√6 * √6 = √36 = 6
Multiplying the last values will give you:
√6 * -√10 = -√60 = -√4*15 = -2√15
Now you can combine all of the resulting values:
2√3 - 2√5 - 2√15 + 6
I believe this is the answer you're looking for.
X = 56°.
Based on the congruence statement, m∠L = m∠P; m∠M = m∠Q; and m∠N = m∠R.
Since m∠L = 72°, m∠P = 72°.
Since m∠N = x°, m∠R = x°.
We are given that m∠Q = 52°.
We can find the value of x by subtracting the given angles from 180:
180-(72+52) = 180-124 = 56°
We are given the inverse function:
sin-1 (0.65)
We can use a scientific calculator to solve this. Make sure that the mode is in radians and not in degrees
So, the answer is
sin-1 (0.65) = 0.7076 which is in radians
The reaction is:
A ( g ) + 1/2 B ( g ) → C ( g )
We will rewrite it so the coefficient in the front of C is 1:
1/2 A + 1/4 B → C
So the rate of increasing of C is 4 times faster than the decrease of B.
The rate of B:
- 1.5 · 10^(-2) M/s : 4 = - 0.375 · 10^(-2) M/s = - 3.75 · 10 ^(-3) M/s
Answer: - 3.75 ·10^(-3) M/s
