Answer:

(2). <em>b - (a + c)i </em>

Step-by-step explanation:

i^{7} = [( i )²]³ × i = ( - 1)³ i = - i

i^{16} = ((i)^2)^{8} = ( - 1)^{8} = 1

((i)^2)^{10} × i = i

a(- i ) + b( 1 ) - c( i ) = - ai + b - ci = <em>b - (a + c)i</em>

Let f(x)=6/-2+2e^-0.3x. what is f(4)? enter your answer rounded to the nearest tenth
pochemuha

The value of the function f(x)=6/-2+2e^{-0.3x} at x=4 after rounded to the nearest tenth is -2.4.

Given Function of x : f(x)=6/-2+2e^{-0.3x}

The given function showing the relationship between x and f(x) is f(x)=6/-2+2e^{-0.3x} where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.

f(4)=6/-2+2e^{-0.3*4}   ( The value of e is 2.7812)

f(4)=-3+2e^{-1.2}                    

f(4)=-3+2*0.30119   (The value of e^{-1.2} is 0.30119)          

f(4)=-3+0.60238

f(4)=-2.3972

Round -2.3972 to tenth is -2.4.

Hence the value of function of at x=4 is -2.4.
