Answer:
No.
Step-by-step explanation:
The logarithm of a number to the base b of a certain number is the exponent
to which the base b is raised to equal the given value.
So say we have logb y = a, then
y = b^a
So if y = 0 then
0 = b^a
If b is a positive number then there is no value of a that makes y = 0.
for example y = b^0 = 1, y = b^1 = b etc.
-8 I believe is the answer
Answer:
.6601
Step-by-step explanation:
to find u, which we assume is an angle of course, we can take arctan of both sides. so arctan(-7.721) = -1.4420. this angle is in quadrant 4, but it is not in the range. In this instance you just go around the circle again, or add 2pi, which gets us 4.8412. You can check and you get the same answer if you take the tangent of either.
So now we have a number in the appropriate range in the appropriate quadrant. That means we have the correct angle. The question asks what is sine of that angle cut in half. so sin(4.8412/2), which gets you your answer. let em know if something didn't make sense.

Step-by-step explanation:
1. The required line passes through 
. The slope of the line joining the points 
is given by the formula,
or 
Either of them yields the same result.
Substitute 
into the first formula to get,
You can write this as a mixed number to obtain:
2. The given line passes through 
.
Observe that the first coordinates are the same for both points. This implies that, the line is vertical.
The slope of all vertical lines are undefined.
3. The average rate of change of the function 
on the interval ![[a,b]\:\:or\:\:a\le x\le b](https://tex.z-dn.net/?f=%5Ba%2Cb%5D%5C%3A%5C%3Aor%5C%3A%5C%3Aa%5Cle%20x%5Cle%20b)
