Answer:
about 6 miles per hour
Step-by-step explanation:
divide 350 by 57 to get your answer ;)
2x⁴+17x²+8
Let X = x² →→(x = + or -√X )
The quadratic becomes : 2.X² + 17.X + 8. Now solve for X:
X' = [-b+√(b²-4ac)]/2a and X" = [-b-√(b²-4ac)]/2a
Plug I the values of a, b and c and you will find;
X' = -1/2 and X" = - 8
Since X = √x → →X' = √( -1/2) [imaginary roots]
and X" = √-8 →→ X" = 2√-2 [imaginary roots]
Then:
1st ROOT: X' = - √1/2.i
2nd ROOT: X" = + √1/2.i
3rd ROOT: X" = + 2√2.i
4th ROOT: X" = - 2√2.i
Answer:
t = 8/9
Step-by-step explanation:
There are many possible solutions that could be expressed as equivalent to the equation 10t - 4t + 3t = 8. With that being said, here is a simplified form, solved for t.
10t - 4t + 3t = 8
6t + 3t = 8
9t = 8
t = 8/9
Each of these form's is an equivalent equation to the one written by Mrs. McAlister.
If you can provide the table of student answers, we could answer which students were correct or wrong. Without the table, we can only guess.
