Answer:
I hope this helps-How to define a logarithmic unction-
Step-by-step explanation:
Therefore, the (multiple-valued) logarithmic function of a nonzero complex variable z=reiΘ is defined by the formula logz=lnr+i(Θ+2nπ)(n∈Z).
Some basic properties of the function logz are the following:
log(z1z2)=logz1+logz2.
log(z1z2)=logz1−logz2.
There may hold Log(z1z2)≠Logz1+Logz2.
25.26 miles
you just divide the already given amount of minutes with the miles that were already ridden, you get that answer. then you times it by 4 and you get it
Answer:
and 
the mistake was in calculating 
let's solve first.
Step-by-step explanation:
if 
, substitute the 
in the equation
as
solve the equation in parentheses :
multiply 
by 
it will equal to: 
now we want to let all unknown digits alone, so we will take 
to the other side with a different sign it will be as:
now we will solve it:
at this part, the given equation was wrong in the paper.
we don't want the digit to be negative so we will do it like this:
now that we found 
we will substitute it to find 
:
overall the mistake was in calculating instead of putting
he/she put a different sign in front of the digit like :
so when he/she flipped 
it became positive and instead of subtracting he/she added it.
Answer:
24 ft up the wall
Step-by-step explanation:
We can use the Pythagorean theorem to solve, letting the 25 ft ladder be the hypotenuse
a^2 +b^2 = c^2
7^2 +b^2 = 25^2
49 + b^2 = 625
Subtract 49 from each side
49-49 +b^2 = 625-49
b^2 = 576
Take the square root of each side
sqrt(b^2) = sqrt(576)
b = 24
We only take the positive solution since length cannot be negative
The ladder will reach 24 ft up the wall
