Step-by-step explanation: The base of the power in the original equation becomes the base of the log. So we have 
.
Next, the exponent in the original equation goes on the other side of the equation and finally, the result in the original equation goes inside the log.
So we have 
which is 3² = 9 written in logarithmic form.
This can also be switched around to read 
.
So the first choice will be your answer.
My work is also show in the image attached,
I just didn't switch it.
Answer:
17/7 or 2 3/7
Step-by-step explanation:
3 is the same as 21/7. Subtract 21/7-4/7 to get 17/7.
Hope it helps!
Answer:
( 
, 0) and (8, 
)
Step-by-step explanation:
Curve is concave downward when the second derivative is negative.
y' = 
, by the Fundamental Theorem of Calculus
y'' = 
, which has a denominator that is always positive. The numerator 
is negative when x > 0 and when x < 8. So that is when y'' is negative, and consequently when the curve y is concave down.
First of all, the angle bisector, ray and angle line are all lines. Please refer to the picture attached. All of these lines are joined at one point called vertex which is at point O. The angle bisector is the line that divides the total angle into half. In this case, that would be line OB. The ray and line are the two legs of the angle, which are line OA and line OC, respectively. The angle is the arc between the lines.
