<span>3.00x10^8 meters.
If I'm reading this problem correctly, light is traveling at 9.45x10^15 meters per year and that there's 3.15x10^7 seconds per year. So you desire to know the speed of light in meters per second. This is mostly an exercise in handing scientific notion. So we need to divide the total distance that light traveled by the number of seconds. With scientific notation, you divide the significands and subtract the exponents to perform division. So
9.45 / 3.15 = 3 ; Dividing the significands
15 - 7 = 8 ; Subtracting the exponents.
So the answer is 3x10^8 meters per second.
Since our data has 3 significant figures, the result should also have 3 significant figures, so the final result is 3.00x10^8 meters.</span>
Answer: 4/7
Step-by-step explanation:
Multiply 5/7 by 4/5. The keyword is "of" which means multiply. Once you multiply them, you will get 20/35. You can simplify this to 4/7.
Answer:
Remember, a homogeneous system always is consistent. Then we can reason with the rank of the matrix.
If the system Ax=0 has only the trivial solution that's mean that the echelon form of A hasn't free variables, therefore each column of the matrix has a pivot.
Since each column has a pivot then we can form the reduced echelon form of the A, and leave each pivot as 1 and the others components of the column will be zero. This means that the reduced echelon form of A is the identity matrix and so on A is row equivalent to identity matrix.
Answer:
1/32
Step-by-step explanation:
Multiply the fractions together
1/8 * 1/4 = 1/32
1/32 are left handed glass wearers
