Answer:
<u>The</u><u>r</u><u>e </u><u>are </u><u>5</u><u>0</u><u> </u><u>oranges </u><u>in </u><u>the </u><u>box.</u>
Step-by-step explanation:
Weight of box = 4 kg = 4000 g
Weight of 1 orange = 80 g
No. of oranges in the box = ?
No. of oranges in the box = Weight of the box / Weight of 1 orange
No. of oranges in the box = 4000 / 80 = <u>50 oranges.</u>
Answer: Option c. D: all real numbers R: (y ≥ 8.75)
Solution:
y=x^2+x+9
Domain: all real numbers = ( - Infinite, Infinite)
y=ax^2+bx+c
a=1 > 0, the parabola opens upward: Range: y ≥k
b=1
c=9
Vertex: V=(h,k)
h=-b/(2a)
h=-1/(2(1))
h=-1/2
h=-0.5
k=y=h^2+h+9
k=(-0.5)^2+(-0.5)+9
k=0.25-0.5+9
k=8.75
Range: y≥k
Range: y≥8.75
