A circle has a diameter with endpoints of (-3, 8) and (7, 4). What is the center of the circle?

1 answer:

5 0

The center of the circle is expressed as (h,k) in the standard form of equation. In this case, the diameter endpoints are (-3, 8) and (7, 4). Hence the circle center has coordinates which are the midpoints of the two points.

x = (-3 + 7) /2 = 2
y = (8 + 4) /2 = 6

hence the center of the circle is (2,6)

Jackson is starting an exercise program. The first day he will spend 30 minutes on the treadmill. He will increase his time on t

yulyashka [42]

Answer:

40 minutes.

Step-by-step explanation:

time spent on the thread mill as a function of d(day) = t(d)

= 30 +2(d-1) minutes

[where d represents day number]

(when d is 1 the time spent should be 30

so substitute d=1 and check it will be 30 only.

on first day he will spend 30 minutes so, I added 30 .

and on every additional day( these additional days are excluding first day), he will increase the time by 2 minutes.so, I added 2(d-1) to initial 30 minutes)

so, T(6), the minutes he will spend on the treadmill on day 6=

=30+2(6-1)

=30+2(5)

=30+10

=40 minutes
