Answer & Explanation:
To find the direction cosines of the vector a is need to divided the corresponding coordinate of vector by the length of the vector. The coordinates of the unit vector is equal to its direction cosines. Property of direction cosines. The sum of the squares of the direction cosines is equal to one.
Answer:
The distributive property helps in making difficult problems simpler. You can use the distributive property of multiplication to rewrite expression by distributing or breaking down a factor as a sum or difference of two numbers.
Here, for instance, calculating 8 × 27 can made easier by breaking down 27 as 20 + 7 or 30 − 3.
Step-by-step explanation:
Answer:
54
Step-by-step explanation:
216 - 3x = 324 -5x
subtract 216 from both sides
add 5x to both sides
divide both sides by 2x.
396/x - 10 = -22
396/x = -22 + 10
396/x = -12
X = -396/12
X = -33
Answer:
18.75
Step-by-step explanation:
I GOT THIS QUESTION TOO I ACCIDENTALLY PUT THE WRONG ANSWER BUT THE ANSWER IS TOOK HALF IF 16=8
AND TOOK HALF OF 20=10 THAN I TAKE 10x15=150 THAN I
DIVIED WITH 8 WHICH IS [ ANSWER: 18.75 cm ] I THINK ITS RIGHT!!
