Answer:
The annual interest rate is 12.05%.
Step-by-step explanation:
The simple interest is given by the formula:

Where I denotes interest.
P denotes the principal amount.
R denotes the rate of interest
and T denotes the time period.
I=$160.67, P=$2000, t=8 months=8/12 years (Since 12 months=1 year so 1 month=1/12 year)

Hence, the annual interest rate is 12.05%.
Answer:
A parabola is continuous but for y to be function of x the axis must be parallel to the y axis and for x to be a function of the y axis must be parallel to the x axis
Answer:
2x - 2y = -8
x + 2y = -1
3x = -9
x = -3
-3 + 2y = -1
2y = 2
y = 1
(-3, 1) is the solution

Answer:
Polynom degree: 5
Y intercept point: (0, 80)
Step-by-step explanation:
P(x)=(x+5)(x+4)²(x+1)²
When you expand, the highest power of x is 1 for first term (x+5), 2 for second term (x+4)² and again 2 for (x+1)². Overall, x⁵ will be the x term with highest power. So the degree of the polynom is 5.
The y intercept, i.e. intersection with OY axis, happens for x=0. Thus, P(0)=5×4²×1²=5×16=80. The y intercept point is (0, 80)
