Answer:
Step-by-step explanation:
This isn't the same thing although you will get some factors that have i in them
(x^4 - 64) factors using the difference of squares.
(x^2 - 8)(x^2 + 8) Both of these factor using the difference of squares.
(x^2 - 8): factors into (x + sqrt(8) )(x - sqrt(8) )
(x^2 - 8): factors further (x + 2*sqrt2)(x - 2sqrt(2)
(x ^2 + 8) : (x + sqrt(8)i ) (x - sqrt(8)i )
(x^2 + 8) : (x + 2sqrt(2)i) (x - 2sqrt(2)i)
Final answer
(x + 2*sqrt2)(x - 2sqrt(2)(x + 2*sqrt2)(x - 2sqrt(2)
Answer: 299 m/s
Step-by-step explanation:
The first step is to take the first derivative of the equation given. This will give us the equation for velocity which we will then substitute the 7 in for t.
To derive the equation you multiply the coefficient by the power of the variable, then subtract one from the variable.
v(t) = 6t^2 + 5
Now input 7 in for t to find the velocity.
v(7) = 6(7)^2 + 5
v(7) = 299 m/s
There is no solution. Here is the explanation with both of the methods :)
