If auto insurance cost $8.00 per $1,000 of coverage what is the cost to insure a car valued at 15,400?
Zina [86]
If you would like to know what is the cost to insure a car valued at 15400, you can calculate this using the following steps:

$8 ... $1000
$x = ? ... $15400

8 * 15400 = 1000 * x    /1000
x = 8 * 15400 / 1000
x = $123.2

The correct result would be $123.2.

What is the product of z1 and z2 if
MaRussiya [10]

Answer:

308[cos(45) + isin(45)]

Step-by-step explanation:

z1×z2:

Modulus: r1 × r2

= 7×44 = 308

Argument: theta1 + theta2

= -70 + 115 = 45

z1z2 = 308[cos(45) + isin(45)]

Or

z1z2 = 154sqrt(2) + (i)154sqrt(2)

sqrt: square root
