Answer:
x = ±2
Step-by-step explanation:
A equation is given to us , which is ,
From <u>properties </u><u>of </u><u>logarithm </u>we know that ,
Applying this to LHS , we have ;
Now the bases of logarithm on LHS and RHS is same . On comparing , we have ;
Put square root on both sides,
Simplify ,
This is the required answer.
We have that
2sin²<span>x - sinx - 3 = 0
</span>
Let
A------> sin x
so
2A²-A-3=0
using a graph tool-----> to resolve the second order equation
see the attached figure
the solutions are
A=-1
A=1.5------> is not solution because sin x <span>can not be 1.5
the solution is
A=-1
therefore
sin x=-1
x=arc sin(-1)=-90</span>°
the answer is
sin x=-1x=-90° or 270°
Answer: The answer is 4x^4 to the cube root of 2x^2

Answer:
broo its been so long its 2020 now dude and ur question is a most recent bruhhhhhhhhhhhhhhhhhhhhhhhhh
Step-by-step explanation:
Answer: The solutions are not viable because the amount of the sale cannot be negative.
Step-by-step explanation:
The solution A = -5 is not viable because A represents the amount of sale in dollars and so cannot be a negative number. The minimum amount that a person can make from sales is $0 so anything less than that is not viable.
For instance, if you are selling shoes for $4 each and make no sales in the day, your sales would be $0. It is not possible that your sales would be -$4.
