Which set of measurements can represent the lengths of a triangle's sides?
zepelin [54]
Triangle, not a triangle, not a triangle, triangle

Determining if three side lengths can make a triangle is easier than it looks. All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.[

kenny6666 [7]

Answer:

\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3

Step-by-step explanation:

f(x)=-4x^2-3x-4

f(x+h)=-4(x+h)^2-3(x+h)-4

f(x+h)=-4(x^2+2xh+h^2)-3(x+h)−4

f(x+h)=-4x^2-8xh-4h^2-3x-3h-4

f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4-(-4x2-3x-4)

f(x+h) - f(x)=-4x^2-8xh-4h^2-3x-3h-4+4x2+3x+4

f(x+h) - f(x)=-8xh-4h^2-3h

f(x+h) - f(x)=h(-8x-4h-3)

\dfrac{f(x+h) - f(x)}{h}=\dfrac{h(-8x-4h-3)}{h}

\dfrac{f(x+h) - f(x)}{h}=-8x-4h-3

Brainliest answer guaranteed <br> URGENT
UNO [17]

Answer:

y=-6.6 and y=10.6

Step-by-step explanation:

The given ellipse has equation:

\frac{(y-2)^2}{64}+\frac{x^2}{9}=1.

The center of this ellipse is (h,k)=(0,2)

We use the equation: a^2-b^2=c^2 to determine the foci.

\implies 64-9=c^2

\implies 55=c^2

\implies c=\pm \sqrt{55}

The directrices are given by y=k\pm\frac{a^2}{c}

y=2\pm\frac{64}{\sqrt{55}}

y=2\pm8.6

y=2-8.6 and y=2+8.6

The equation of the directrices are:

y=-6.6 and y=10.6

The correct answer is D
