Hello :
<span>(3x²+kx-1) is a quadratic polynome when : a =3 , b=k , c= -1
the discriminat </span>Δ = b²-4ac ≥ 0 because ac = -3 <span><<span> 0
-4ac </span></span>>0 and b²<span>≥0
the </span> quadratic polynome has :2 solutios or 1 solution (Change of sign)
conclusion : <span>is never always positive for any value of k</span>
Solve for n :
N=9
...........
Answer:
Angle 1 is 67 and Angle 2 is 46
Step-by-step explanation:
Answer:
DEH and HEJ are complementary angles for example.
Step-by-step explanation:
We need to provide any 2 angles that sum to 90deg. We can clearly see that DEH and HEJ are complementary, we can see the same for JEK and KEF.
I don't believe there's more.
Since decimals have places in 10 100 and 1000 you need a denominator with those number but since you already have a 10 you take the 7 and add a 0. in front so the answer is 0.7
