X - 3
if x = 7 then 7 - 3 = 4
answer
4
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
Answer:
250
Step-by-step explanation:
1. convert from percentage to decimal
to do this, divide the percentage by 100
1.11 / 100 = 0.0111
2. multiply the decimal by the amount
decimal = 0.0111
amount = 22500
final answer = 0.0111 * 22500 = 249.75 ≈ 250
thus, 1.11 % of 22,500 = 0.0111 * 22500 ≈ 22500
Given that the area of a 15° secant has an area of 11.9 m2, then the area of the circle will be given by:
(Total measure in degrees of the circle)/(measure in degrees of the secant)*(area of secant)
=360/15*11.9
=24*11.9
=285.6 m^2
Answer: 285.6 m^2
