D slope is rise over run ( gain in y over gain in x) 2 over one is Two
Answer:There you go X is the middle, a only brother, b only sister.
a X =11
b X =9
a b X =14 (20-6)
a b 2x=20
X=6
So 6 in the middle, 6 on the outside, 5 only brothers, 3 only sisters. let me know if I missed anything but we have a total of 20, 6 with none, 11 with brothers and 9 with sisters
Step-by-step explanation:
Answer:
(x +1)^2 +(y +2)^2 = 85
Step-by-step explanation:
The equation of a circle with center (h, k) and passing through (a, b) is ...
(x -h)^2 + (y -k)^2 = (a -h)^2 +(b -k)^2
Filling in your numbers gives ...
(x -(-1))^2 +(y -(-2))^2 = (6 -(-1))^2 +(4 -(-2))^2 = 49 +36 = 85
(x +1)^2 +(y +2)^2 = 85
Answer:
Independent variable (x in 2D cartesian) = t (time)
Dependent variable (y in 2D cartesian) = p (battery power)
The independent variable is <u>time</u>.
The dependent variable is <u>battery power</u>.
Time is independent because it cannot be controlled.
Battery power is dependent because it can be controlled.
Since t is in hours,
The battery power begins at <u>100%</u> and decreases <u>5%</u> each hour.
