Answer:
D. tan(-π/6)
Step-by-step explanation:
The tangent function is periodic with a period of π, so ...
tan(5π/6) = tan(5π/6 ± kπ) . . . for any integer k
For k = -1, we have ...
tan(5π/6) = tan(5π/6 -π) = tan(-π/6)
If the smaller number is x, then the larger number has to be 20 - x in order for the arithmetic mean to be 10, as their sum must be 20.
If the geometric mean is 8 the product of the numbers has to be 64 and so the larger number is 64/x
Solving 64/x = 20 - x gives the quadratic x^2 -20x +64 = 0 so x = 4 or 16.
The two numbers are 4 and 16.
Answer:
Yes
Step-by-step explanation:
(8,8) is a solution is y=x.
If we substitute the point into the equation, the equation is true.
(8,8) is in (x,y) format
Substitute:
y=x
8=8
LS=RS (left side equal rights side)

Step-by-step explanation:
Becky went scuba diving. The inequality statement compares the magnitude of two depths that she reached.
1-28] > 1-3
What does the inequality statement show?
Select from the drop-down menus to correctly complete the statement.
-28 is greater
than-3, but 28 m below sea level is a greater
depth than 3 m below sea level.
