g find the 2 components of vector b = 2i + j - 3k, one parallel to a = 3i - j and another one perpendicular to a

The components of parallel and perpendicular to are and , respectively.

Step-by-step explanation:

Let be and , the component of parallel to is calculated by the following expression:

Where is the unit vector of , dimensionless and is the operator of scalar product.

The unit vector of is:

Where is the norm of , whose value is determined by Pythagorean Theorem.

The component of parallel to is:

Now, the component of perpendicular to is found by vector subtraction:

If and , then:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)
