78,000 rounded to the nearest ten thousand is 80,000.
Answer:
1520.5 in^2
Step-by-step explanation:
Surface area=2*pi*r^2+2*pi*r*h=2*pi*r*(r+h)=2*pi*11*22=1520.5 in^2
Answer:
xy(y - x)(y + x)
Step-by-step explanation:
take out a common factor xy from both terms
= xy(y² - x²)
y² - x² is a difference of squares and factors in general as (y - x)(y + x)
Hence
xy³ - x³y = xy(x - y)(x + y)
So (f-g)(x) = 3x2 + x, so when x = 2, the function is 14
