Answer:
0.435897 km per minute
Step-by-step explanation:
Answer:
a) 186
Step-by-step explanation:
g(x) = 7(x^2 + 3) - 10
g(5) = 7((5)^2 + 3) - 10
g(5) = 7(25 + 3) - 10
g(5) = 7 × 25 + 7 × 3 - 10
g(5) = 175 + 21 - 10
g(5) = 186
One way is to factor and group and get every 3
729=3 times 3 times 3 times 3 times 3 times 3
so we group the ones that happen 3 times
729=(3*3*3) times (3*3*3)
we know that we can take the cube root of each group and multiply the result
729=
![( \sqrt[3]{3*3*3})( \sqrt[3]{3*3*3})](https://tex.z-dn.net/?f=%28%20%5Csqrt%5B3%5D%7B3%2A3%2A3%7D%29%28%20%5Csqrt%5B3%5D%7B3%2A3%2A3%7D%29)
=(3)(3)=9
the answer is 9
Answer:
5 × 1.6 = 8. The answer is 8 pounds.
Step-by-step explanation:
If you multiply 5 and 1.6, you get 8.
These techniques for elimination are preferred for 3rd order systems and higher. They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b. Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method. As the system of equations increases, the "condition" of a matrix becomes extremely important. Some of this may sound completely alien to you. Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n') become larger than 2.
