Answer:

1.  16

2.  -4

Step-by-step explanation:

First factor the expression

lim x→1  (x^3 + 5x^2 + 3x-9)/(x-1)

lim x→1  (x-1) (x+3)^2/(x-1)

Canceling the x-1  in the top and bottom

lim x→1   (x+3)^2

Let x=1

lim x→1   (1+3)^2 = 4^2 = 16


2.  lim x→0 (x^2 -6x+8) /(x-2)          

First factor the expression

    lim x→0 (x-4) (x-2) /(x-2)        

Canceling the x-2  in the top and bottom

lim x→0 (x-4)

Let x=0

lim x→0   (0-4) = -4

Filling in the table

x     -.1      -.01       -.001     .001     .01     .1

f(x) -4.1  -4.01    -4.001   -3.999   -3.99  -3.9

Larissa practices for a swimming tournament
scoundrel [369]

Answer:

Larissa takes 59.141 seconds to complete both laps.

Step-by-step explanation:

The complete time is the sum of time taken on each lap. We translate the two statements into mathematical expressions to determine the required output:

(i) <em>She completes her first lap in 31.135 seconds</em>:

x_{1} = 31.135\,s

(ii) <em>She completes her second lap 3.129 seconds faster than the first lap</em>:

x_{2} = x_{1}-3.129\,s

x_{2} = 31.135\,s - 3.129\,s

x_{2} = 28.006\,s

Then, the time taken by Larissa to complete both laps is:

\Delta x = x_{1} + x_{2}

\Delta x = 31.135\,s+28.006\,s

\Delta x = 59.141\,s

Larissa takes 59.141 seconds to complete both laps.

What is the value of the expression |a + b| + |c| when a = –6, b = 2, and c = –11?
iVinArrow [24]
The answer is D. -15 because I am assuming that the vertical lines mean brackets, and we have to work out the brackets first (according to BIDMAS). Doing so, -6 + 2 = -4 and -4 + -11 = -15.
