Mark records his science scores in each monthly assessment over a period of 5 months. in the first assessment, he scores 76%. in the second assessment, he scores 73%. after that, his scores keep increasing by 2% in every assessment. assume that x represents the number of assessments since he starts recording and y represents the scores in each assessment.

which of the following describes the situation?

a function only
b.
neither a function nor a relation
c.
a relation only
d.
both a relation and a function

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75

i hope this and i hope you get it right. it took me a while to get this done for you. : )

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
