Solve the following equation for x.
Answers
Answer:
If you just solve normally, you will get x=2 and x=-3. But if you plug these in to check your work, you will find that they are wrong. Your answer is no solution
Step-by-step explanation:
ln(2x+3)+ln(x-2)=ln(x^2-2x)
Rule: log(a) + log(b) = log(a*b)
ln( (2x+3)(x-2) ) = ln(x^2-2x)
Rule: If log(a) = log(b) then a = b
(2x+3)(x-2) = x^2 - 2x
2x^2-x-6=x^2-2x
x^2+x-6=0
Using Quadratic Formula:
x = 2 and x = -3
But, plugging these numbers back into the original equation is false!

Tue diameter of a bike is 27 inches if the wheel makes 15 complete rotations how far does the bike travel?
Answers
Answer:
1271.7 inches
Step-by-step explanation:
Given
[tex]d = 27in[/tex]
[tex]Rotations = 15[/tex]
Required
The total distance moved
First, we calculate the circumference of the wheel
[tex]c = \pi *d[/tex]
[tex]c = 3.14 * 27[/tex]
[tex]c = 84.78[/tex]
This represents the distance traveled in one complete rotation.
So, in 15 rotations.
[tex]Total = 15 * 84.78[/tex]
[tex]Total = 1271.7[/tex]

Answers
Answer:
See Below.
Step-by-step explanation:
Remember that:
If c² > a² + b², then we have an obtuse triangle. If c² < a² + b², then we have an acute triangle. And if c² = a² + b², then we have a right triangle.Where c is the longest side, and a and b are the two remaining sides.
[tex]4^2\text{ is }\textbf{ less than (or $<$) } 3^2+3^2[/tex]
[tex]\text{Therefore, }\Delta JKL \text{ is }\textbf{an acute triangle.}[/tex]
(16 is less than 9 + 9 or 18.)
[tex]5^2\text{ is } \textbf{equal to (or $=$) } 3^2+4^2[/tex]
[tex]\text{Applying the same method, $\Delta ABC$ is }\textbf{ a right triangle.}[/tex]

Help plssss I need to find mr pryor account balance
Answers
Answer:
$1,462.50
Step-by-step explanation:
We are to find the total amount after 4 years
Principal => $1,250
Rate => 4.25%
The formula to find the total amount =
A = P(1 + rt)
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year.
Solving our equation:
A = 1250(1 + (0.0425 × 4)) = 1462.5
A = $1,462.50
The total amount accrued, principal plus interest, from simple interest on a principal of $1,250.00 at a rate of 4.25% per year for 4 years is $1,462.50.
