Answer: It decreased by 24F not 10F because if it were 10F the starting temperature had to be -7F since the difference between this number and -17F is 10F but in this case it starts at 7F so we subtract 7-0=7 and 17-0=17 and add 17+7=24F.
Step-by-step explanation:
7-0=7
17-0=17
17+7=24F

Answer:
angle of each sector =360/8=45°
angle between C and H=135°
hence the answer
For a quadratic of the form
, we complete the square by first adding
to each side.
Here, the coefficient b is equal to 10. We take half of this—5—and square it to get 25. We add this to both sides of the equation.
FYI, this equation can easily be factored, so there's no need to complete the square.
