Solve the equation below for x. 100 = 25e3 In4 O A. 4 B. 3 e O C. X=In4 - 3 c In100 3. In25 O D.

Ray Of Light [21]

Dividing the given equation by 25 we get:

$\begin{gathered} \frac{100}{25}=\frac{25e^{3x}}{25}, \\ 4=e^{3x}\text{.} \end{gathered}$

Applying the natural logarithm to the above equation we get:

$\ln (4)=\ln (e^{3x})=3x\ln (e)=3x\text{.}$

Finally, solving for x we get:

$x=\frac{\ln (4)}{3}\text{.}$

1. In Kite ABCD below, point E is the midpoint of segment BD. What are the

Anvisha [2.4K]

Answer:

The coordinates of point D( 4,4)

Step-by-step explanation:

Step(i):-

Given points are E(10,4) and B(16,4)

'E' is the mid-point of segment BD

Let D(x₁, y₁) be a point

E = midpoint of segment BD

$(10,4) = (\frac{x_{1} +x_{2} }{2} , \frac{y_{1} +y_{2} }{2} )$

$10 = \frac{x_{1} +16 }{2}$

20 = x₁ + 16

20-16 = x₁

x₁ =4

Step(ii):-

$\frac{y_{1} +y_{2} }{2} = 4$

$\frac{4 +y_{2} }{2} = 4$

4 + y₂ = 8

y₂ = 8-4 =4

The co-ordinates of point D( 4,4)
