A corporation has three factories, each of which manufactures acoustic guitars and electric guitars. In the matrix 70 35 25 A= 100 50 70 aij represents the number of guitars of type i produced at factory] in one day. Find the production levels when production increases by 20% Need Help?

84 42 30 = 120 60 84

Step-by-step explanation:

Hi, to solve this problem we have to multiply everything in the matrix by the value of 1.2 (which is the same as 120%).

We have to apply scalar multiplication, where the regular number (1.2) is multiplied by every entry on the matrix.

So, mathematically speaking:

70 (1.2) 35(1.2) 25(1.2) A= 100(1.2) 50(1.2) 70(1.2)

84 42 30 = 120 60 84

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
