Answer: All real numbers greater than or less than 9.
Step-by-step explanation: The range is possible y-values. In a parabola the range starts at a particular place then it either goes up or goes down. Since the leading factor has a negative in front of it, the parabola will open downward meaning most likely all y-values will be lest than the include max point. Now let find the max point using the formula -b/2a then substituting that into the parabola. -2/2(-1)= 1, then plug it in. y=-(1^2)+2(1)+8 which equal -1+2+8 which equal 9 so the max point is 9. Since the graph open downward all the points that are possible will either be at 9 or below it so the range is All real numbers greater than or less than 9. or (-∞,∞)∪(∞,9]
Answer:
4.89 cm
Step-by-step explanation:
Formula for arc length = (angle/360)×2×pi×r
(70/360)×2×pi×4 = 4.89cm
Answer:
10.28
Step-by-step explanation:
Using ratio
12 : 9
8 :x
Crose multiple
12x = 72
Make x subject formula

Answer: 12 pounds
Step-by-step explanation:
0.80x + 3 = $12.60
-3 -3
0.80x = $9.60
9.60 / 0.80 = 12
x = 12 pounds
