Which is the more precise measurement? 18 inches 18.55 inches 17.5 inches 19.775 inches

option D

Step-by-step explanation:

the correct answer is option D

A precise measurement is one in which we can measure the smallest of the value.

In 17.775 we can measure the smallest value of 0.001

In 18.55 we can measure smallest value  up to 0.01

In 17.5 we can measure smallest value  up to 0.1

In 18  we can measure smallest value of 1.

hence, the correct answer will be option D which will be 17.775 in which we can measure 0.001 value.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
