Answer:
square so all sides are equal
bc^2+mc^2=bm^2
16x^2+4x^2=20x^2=2root5x
nd^2+dm^2=nm^2
x^2+4x^2=5x2=root5x
then:-
1/2*b*h=1/2*2root5x*root5x
=1/2*10x^2=5x^2
The vertex is at -b/(2A). if you use the foil method it will come out to -(x^2+2x+1)+4. then distribute the negative and simplify the equation (add the four) the equation comes out to be -x^2-2x+3. The vertex is at x=2/(2*-1), which is -1. plug -1 into the original equation to find y, (y=-(-1)^2-2*(-1)+3) which is y=4. so the vertex is at (-1,4). then since the parabola opens down (negative a value) and has a maximum at 4, y is always less than or equal to 4. x is all real numbers as it goes on forever. so b is your answer.
The power rule applies to each term.
... (d/dt)(t^n) = n·t^(n-1)
... g'(t) = 2t +5
... g'(7) = 2·7 +5 = 19
Answer:
B&C: tan F=0.0833 & tan H=12.0000
Step-by-step explanation:
The tangent relationship is always opposite/adjacent.
When F is the reference angle, side GH (1) is the opposite side and side FG (12) is the adjacent.
1/12 is 0.0833
When H is the reference angle, FG (12) is the opposite and GH (1) is the adjacent.
12/1 is 12.
