Which choice shows the sum of the two vectors< -2 ,0> and < 4,-5> written as an ordered pair

a. < 4,-5>
b. < 2,-5>
c. < -2,0>
d. < -6,5>

B. <2,-5>

Step-by-step explanation:

We are given the vectors,

u = <-2,0> and v = <4,-5>

It is required to find the sum of the vectors i.e. u + v.

So, we have,

u + v = <-2,0> + <4,-5>

i.e. u + v = < -2+4 , 0-5 >

i.e. u + v =  <2,-5>

Thus, the sum of the vectors written as ordered pairs is <2,-5>.

Hence, option B is correct.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

the answer is 13 cm
