Tan 2x = 2 tan x / (1-tan^2x)

hence, tan 2x = 1
2x = pi
x = pi/2.

What is the average rate of change for the sequence shown below? (-.5, 2.5), (0,3. (.5, 3.5). (1,4)
zhannawk [14.2K]

Answer:

The average rate of change for this sequence is 1

Step-by-step explanation:

The average rate of change is calculated as the slope of the line joining the end points of the sequence.

In this case the end points are;

(-.5, 2.5) and (1,4)

We simply calculate the slope using the gradient formula;

Change in y / change in x

(4 - 2.5)/(1 - -0.5) = 1

Please help!! ASAP!!
kotegsom [21]

Answer:

26. t<-70 see description below.

Step-by-step explanation:

To solve an inequality in one variable, solve using inverse operations like any other equations. However, if dividing or multiplying by a negative at any points, flip the sign of the inequality.


Example:

\frac{t}{-7}>10\\\\ -7*\frac{t}{-7} >10*-7\\\\t

-7 was multiplied to as an inverse operation to division by -7. Because it was negative, the inequality sign was flipped. To graph, plot -70 on the number line with an open circle. Then draw an arrow from -70 to the left.
