Evaluate the limit 9n^3 + 5n - 2/2n^3

VikaD [51]

Answer:

9/2 if n goes to infinity and that the 2n^3 is under the whole expression

Step-by-step explanation:

Let me clear this .

find limit (9n^3 + 5*n - 2)/ (2n^3)

as n --> infinity

Did I put the parentheses in the right spot?

because if you leave it the way you did, then the whole expression goes to positive infinity as n goes to infinity But I will do this with parentheses

find limit (9n^3 + 5*n - 2)/ (2n^3)

simplify expression

limit (9/2) + 5/(2n^2) - 1/(n^3)

= (9/2) + 0 - 0

= (9/2)

On a coordinate plane, a dashed straight line with negative slope goes through (0, 1) and (2, negative 2). Everything to the lef

charle [14.2K]

Answer:

$y$

Step-by-step explanation:

The straight line passes through (0,1) and (2,-2).

Equation of a straight line passing through two points (x1,y1) and (x2,y2)

is given by:

$y-y_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x_{1})$

$y-1=\frac{-2-1}{2-0}(x-0)$

$y=-\frac{3}{2}x+1$

Everything to the left of the line is shaded.

We have to visualize the graph:the straight line has a positive y-intercept and a negative slope.The graph is given in the attachment below.

From the figure we can see origin lies on the shaded region.Hence (0,0) should satisfy the inequality.

LHS=y=0

RHS= $-\frac{3x}{2}+1=1\ (x=0)$

LHS<RHS as 0<1

Hence , the inequality is:

$y$
