Question

Find the length of segment DS with endpoints D(0, 12) and S(-4, 6). Round your answer to the nearest tenth.

Answer 1

Explanation:

Given,

D = ( 0 , 12 )

S = ( -4 , 6 )

we know,

x1 = 0 , y1 = 12

x2 = -4 , y2 = 6

and also,

`d \: = \sqrt{ {(x2 - x1)}^(2) + {(y2 - y1)}^(2) }`

so, after inserting the values we got,

`\sqrt{ {(( - 4) - 0)}^(2) + {(6 - 12)}^(2) } \\ \sqrt{ {( - 4)}^(2) + {( - 6)}^(2) } \\ √(16 + 36) \\ √(52) = 7.2`

so, according to the obtained result the ans is 7.2 and in nearest 10th it is 7.

hope this answer helps you dear! take care and may u have a great day ahead...take care!
