What is the approximate distance between points a and b? a coordinate grid is shown from negative 5 to 0 to 5 on both axes at increments of 1. the ordered pair negative 4, 5 is labeled as a, and the ordered pair 3, negative 2 is labeled as b. 3.74 7.95 8.56 9.90

Distance formula : sqrt ((x2 - x1)^2 + (y2 - y1)^2)
(-4,5)x1 = -4 and y1 = 5
(3,-2)x2 = 3 and y2 = -2
time to sub and solve
d = sqrt ((3 - (-4)^2 + (-2 - 5)^2)
d = sqrt ((3 + 4)^2 + (-7^2))
d = sqrt (7^2 + (-7^2)
d = sqrt (49 + 49)
d = sqrt 98
d = 9.899 rounds to 9.90 <===

The academic affairs council is the highest expert body processing academic affairs, as stipulated by the university statutes. specialist aaro häkkinen (educational policy) took part in the council’s meeting. the agenda of the meeting included bachelors’ feedback, the timing of pedagogical studies, the grant system for tuition fees, the standardisation of administrative practices for internships and the situation of foreign-language and multilingual master’s programmes.
