Step-by-step explanation:
12. n^2+2n
if you insert 1 for k and then work up by inserting 2 for k and adding those together and stoping at n.
13. 8-2(2^n)
if you insert 3 for k and then work up by inserting 4 for k and adding those together and keep on going but stopping at n.
Hope that helps :)
The answer is that they're equal, one is just in point-slope form and the other is in slope-intercept form
-3x-2y=30
-2y=3x+30
y=-3/2x-15
the answer is y=-3/2x-15
Answer:
Speed = 100/Time
Step-by-step explanation:
(a). Speed is a function of time : As seen from equation (1) Speed of the students varies according to the value of time. So, This a true statement.
(b). Time is a function of distance : Distance is not varying in the equation (1), it is fixed to be 100. So, time is not a function of distance because here the distance is made constant. So, This is false statement.
(c). Speed is a function of number of students racing : Speed is not depending on the number of students racing so sped is independent of the number of the students racing. Therefore, Speed is not a function of number of students racing. This is False statement.
(d). Time is a function of speed : As seen from equation (1) Time of the students varies according to the value of their speed. So, This a true statement.
Hence, the true statements are (a) and (d)
