Answer:
B) 5√3
Step-by-step explanation:
84
cancel the numbers from both ends then only 84 will remain
Answer:
(1,2) maximum
Step-by-step explanation:
The vertex is the the point on the graph where the graph does a "u-turn".
this point can either represent the maximum value or the minimum value depending on which way the graph is facing.
In this case, the graph looks like an "n" (as opposed to a "u").
We can clearly see that the point where the graph makes a U-turn is (1, 2)
we can also see that no part of the graph extends above this point, hence this point represents the maximum value which y could possibly be.
Hence (1,2) is maximum
Answer:
1.5 or -5
Step-by-step explanation:
2x²+7x-15=0
Divide by 2:
x²+7x/2-15/2=0
x=-7/2/2 ± √49/4(4)+15/2
=-7/4 ± √49/16+120/16
=-7/4± √169/16=-7/4 ±13/4
=6/4 or -20/4
=1.5 or -5
