Answer:
-10
Step-by-step explanation:
divide both sides by -4
simplify to v+8=-2
subtract 8 from both sides
v=-10
40 meters is 12.00 seconds per meter/ 0.08 meters per seconds
So, x = 13, x = √3 and x =7i.
now, recall that for an EVEN radical, there are two possible roots, namely is say √3 is say hmmm some value "a", that means that a*a = √3, however, -a*-a is also √3, therefore, ±√3 are two valid values, and therefore -√3 is another one.
now.... keep in mind that, complex solutions or roots, never come all by their lonesome, their sister is always with them, the conjugate, so, for 7i or namely 0 + 7i, her sister is always around, 0 - 7i, which is the other root.
Answer:
(-2,1)
Step-by-step explanation:
We want the points where the function is greater than zero
Looking at the function it is between the x intercepts
The x intercepts ares -2 and 1
-2 <x<1 is when y >0
We want interval notation
(-2,1)
