Answer:

a₈ = 11

Step-by-step explanation:

The n th term of an arithmetic sequence is

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 25 and d = - 2, then

a₈ = 25 + (7 × - 2)

= 25 - 14

= 11

Please help! Problem is attached

Darya [45]

Answer:

(a) -3

Step-by-step explanation:

The value of f(x) approaches 3cos(π) = -3 as x approaches π from either direction. The limit is -3.

Additional comment

The fact that the function is defined to have a different value at x=π simply means there is a jump discontinuity there. The function is not continuous, because the limit and the function value differ. That doesn't detract from the fact that there is a limit, and it is -3.

At how many points does the graph of the function below intersect the x-axis?

kotegsom [21]

A. 2 is the right answer

Step-by-step explanation:

Given function is:

$y=3x^2-5x+1$

The graph of any function is made by plugging in the inputs and finding the respective outputs hence creating points on graph.

The graph of function can be created using online graphing tools.

We have used the online graphing calculator "Desmos" to draw the graph of the given function (Picture Attached)

In the picture we can see that the line of graph intersects the x-axis on two points only.

Hence,

A. 2 is the right answer
