Use the fact that 147x16=2352 to write two different multiplication problems that have a product of 2.352

Let 147 × 16 = 2352, from this we get if we multiply a number in the order 1,4,7 it can be integer number or a decimal  number   with another number digits order 1,6 it can be decimal or integer then resulting number digits order becomes 2,3,5,2. Let 147 can be written in different for using the same digits. foe example 147, 1.47.14.7,0.147,0.0147 etc simillarly 16 can be written as 16,1.6,0.16 etc using these numbers we can produce the result 2.352. The produt of two numbers result become a decimal  number depends on the two numbers. So we can write 1.47 × 1.6 =2.352 and 0.147 × 16 = 2.352

step-by-step explanation:

use a calculator!

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12
