Answer:

-39

Step-by-step explanation:

The magnitude of a vector is given by

|| u|| = sqrt( x^2 + y^2)

       = sqrt( 5^2 + (-12)^2)

       = sqrt(25+144)

      = sqrt(169)

     = 13

We are then multiplying by a scalar

||cu|| = -3*13 = -39

Answer:

-39

Step-by-step explanation:

||u|| = sqrt(5² + (-12)²)

= sqrt(25 + 144)

= sqrt(169)

= 13

||cu|| = c ||u||

c = -3

c ||u|| = -3 × 13 = -39

Use compound interest to find the total amount for $845 at 1.25% for 6.5 years
densk [106]

Answer:

$911.02

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.25%/100 = 0.0125 per year,

then, solving our equation

I = 845 × 0.0125 × 6.25 = 66.015625

I = $ 66.02

The simple interest accumulated

on a principal of $ 845.00

at a rate of 1.25% per year

for 6.25 years is $ 66.02.

Allisa [31]

Answer: 2 11/24

Step-by-step explanation:

How many hours does the plane save?

Time taken for the train = 5 1/8

Time taken for the plane = 2 2/3

The number of hours saved will then be:

= 5 1/8 - 2 2/3

Let the lowest common multiple be 24

= 5 3/24 - 2 16/24

= 2 11/24

The number of hours saved by the plane will be 2 11/24
