D. All real numbers
The domain can be anywhere from negative infinity to infinity (-♾️ , ♾️ )
Answer:Suppose the cost stock is x and the cost of fund is y.
Total cost of Nora's portfolio:
100x+200y=3800.....i
Total cost of Erin's portfolio
300x+50y=5350...ii
solving the simultaneous equation by elimination method we proceed as follows:
multiplying eqn by 3 and subtracting ii we get:
550y=6050
thus
y=6050/550
y=11
next, multiply ii by 4 and subtracting i we get:
1100x=17600
x=16
thus the cost of Technology stock was $16 and the cost of mutual fund was $11
Step-by-step explanation:
Given:
ML = 2.3
Angle L = 70 degrees
What we want to find:
MN = x
Use the sine rule
Make sure your calculator is in degree mode
sin(angle) = opposite/hypotenuse
sin(70) = x/2.3
2.3*sin(70) = x
x = 2.3*sin(70)
x = 2.16129302780759
x = 2.2

Answer: 2.2
Answer: The last choice is correct
The function is a parabola U-shaped up... so it's vertex y-value is the lowest y-value of the function.
