Answer:
56 square inches
Step-by-step explanation:
1/2x4x3x2 is 12
4x11 is 44
44+12 is 56
Answer: x-intercept = -1, 1, 2, 3
Answer:
x=39, y=180
Step-by-step explanation:
f(x)=0.4x²-31.2x+788.4
For x=39 the graph reaches its lowest point.
The minimum value of y is:
x=39→y=f(39)=0.4(39)²-31.2(39)+788.4
y=f(39)=0.4(1,521)-1,216.8+788.4
y=f(39)=608.4-1,216.8+788.4
y=f(39)=180
The <u> nominal return </u>on an investment doesn't consider the effect of inflation on purchasing power. If the inflation rate is positive, then the real return will be <u> less than </u> the nominal return on an investment.
Positive inflation eats away at the value of the dollar. For instance, an item worth $100 one year could be worth $105 the next year if inflation was 5%. Therefore, you've lost 5 dollars worth of purchasing power (since you need 5 extra dollars to get the same item).
The formula is
real return = nominal return - inflation
If inflation is positive, then the real return is smaller than the nominal return.
If inflation is negative (ie we have deflation), then the real return is larger than the nominal return.
