Solve In 2 + In x= 5. Round to the nearest thousandth, if necessary.

Answers

The value of x nearest to thousandths is 74.207

Solution:

Given that,

$\text{ln } 2 + \text{ln } x = 5$ ------ eqn 1

We can use logarithmic properties to solve for "x"

Using logarithmic properties:

$\ln (mn) = \ln m + \ln n$

Therefore, apply the above property in eqn 1

$\text{ln } 2 + \text{ln } x = 5\n\n\text{ln } 2x = 5$

By using the logarithmic property,

$\text{If } \ln x = a , \text{ then } x = e^a$

Apply the above logarithmic property in above expression

$\text{ln } 2x = 5\n\n2x = e^5$

Solve the above equation

We know that,

$e^5 = 148.413159103$

[ use calculator ]

Therefore,

$2x = 148.413159103\n\nx = (148.413159103)/(2)\n\nx = 74.2065795513\n\nx \approx 74.207$

Therefore, the value of x nearest to thousandths is 74.207

Could the points (-4,3), (-1,1) and (1,3) form the vertices of a right triangle? Why or why not?

Answers

Answer:

The given points of triangle do not form a right triangle because they are satisfying the property of right angle triangle.

Step-by-step explanation:

Given : The points (-4,3), (-1,1) and (1,3)

To find : Could the points form the vertices of a right triangle? Why or why not?

Solution :

First we find the distance between the points so that we get the length of the sides.

Let, A=(-4,3), B=(-1,1), C=(1,3)

Distance formula is

$d=√((x_1-x_2)^2+(y_1-y_2)^2)$

The distance between point A and B

$|AB|=√((-4+1)^2+(3-1)^2)=√(9+4)=√(13)$

The distance between point B and C

$|BC|=√((-1-1)^2+(1-3)^2)=√(4+4)=√(8)$

The distance between point A and C

$|AC|=√((-4-1)^2+(3-3)^2)=√(25+0)=5$

According to property of triangle,

If the square of larger side of triangle is equating to the sum of square of smaller side $a^2=b^2+c^2$ the triangle is right triangle .

Larger side of the triangle is AC=5 unit and smaller sides are $AB=√(13)$ and $BC=√(8)$

$AC^2=AB^2+BC^2$

$5^2=√(13)^2+√(8)^2$

$25=13+8$

$25\neq21$

So, The given points or the vertices of triangle do not form a right triangle because they are satisfying the property of right angle triangle.

$A=(-4,3),B=(-1,1),C=(1,3)\n |AB|=√((-4+1)^2+(3-1)^2)=√(9+4)=√(13)\n |BC|=√((-1-1)^2+(1-3)^2)=√(4+4)=√(8)\n |AC|=√((-4-1)^2+(3-3)^2)=√(25+0)=5\n L=√(13)^2+√(8)^2=13+8=21\neq5^2\neq\ R$
