Answer: SAS

Step-by-step explanation:

Here, the given triangles AEB and ADC,

B is the mid point of the line segment AC,

⇒ AC = 2 AB,

Also, m∠A = 30°, AD = 8, ED = 4, DC = 6,

\frac{AE}{AD}=\frac{AD-ED}{8}=\frac{8-4}{8}=\frac{4}{8}=\frac{1}{2}

\frac{AB}{AC}=\frac{AB}{2AC}=\frac{1}{2}

⇒  \frac{AE}{AD}=\frac{AB}{AC}

Also,

\angle EAB\cong \angle DAC

Here, ∠EAB of triangle AEB is congruent to the corresponding ∠DAC of another triangle ADC and the sides that include this angle are proportional,

Thus, by SAS postulate of similarity,

\triangle AEB\sim \triangle ADC

⇒ Third option is correct.

patriot [66]
100-0.0124=99.9876

10%=1/10
1/10P=P(0.999876)^t
divide both sides by P
1/10=0.999876^t
take ln of both sides
ln(1/10)=t (ln(0.999876))
divide both sides by (ln(0.999876))
ln(1/10)/(ln(0.999876))=t

Find the second derivative at the point (2,2), given the function below. 2x^4=4y^3
Bogdan [553]

The second derivative at the point (2,2) is 34/9

<u>Explanation:</u>

<u></u>

2x⁴ = 4y³

2x⁴ - 4y³ = 0

We first need to find dy/dx and then d²y/dx²

On differentiating the equation in terms of x

dy/dx = d(2x⁴ - 4y³) / dx

We get,

dy/dx = 2x³/3y²

On differentiating dy/dx we get,

d²y/dx² = 2x²/y² + 8x⁶/9y⁵

\frac{d^2y}{dx^2} = \frac{2 X 2^2}{2^2} + \frac{8 X 2^6}{9 X 2^5}\\  \\\frac{d^2y}{dx^2} = 2 + \frac{16}{9}\\  \\

d²y/dx² = 34/9

Therefore, the second derivative at the point (2,2) is 34/9

Find the difference between the points (6, -3) And (-5,-3)
Varvara68 [4.7K]

We can use the distance formula to find the distance between these points.

Distance formula: \sqrt{(x.2 - x.1)^{2} + (y.2 - y.1)^{2}}

√(-5 - 6)² + (-3 - (-3))²

√121 = 11

The difference between the points is 11.
