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>

Answer:

$h(x) = 57(0.8)^x$

Step-by-step explanation:

Given

$f(x) = 32(0.8)^x$

$g(x) = 25(0.8)^x$

Required

A function that represents the total resale value of the two vehicles

To do this, we simply add up the functions

$h(x) = f(x) + g(x)$

$h(x) = 32(0.8)^x + 25(0.8)^x$

Factorize

$h(x) = (32 + 25)(0.8)^x$

$h(x) = 57(0.8)^x$

Answer:

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.
