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.

__

<em>Additional comment</em>

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 <em>not continuous</em>, because the limit and the function value differ. That doesn't detract from the fact that there is a limit, and it is -3.

Ne4ueva [31]

Answer:

$\$421.60$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=1\ year\\ P=\$400\\ A=?\\r=5.4\%=5.4/100=0.054$

substitute in the formula above

$A=400(1+0.054*1)$

$A=400(1.054)$

$A=\$421.60$

Remember that Interest is equal to

$I=A-P$

$I=\$421.60-\$400=\$21.60$
