Answer:
875 ft²
Step-by-step explanation:
Finding area of similar rectangles:
Scale factor = EF : AB
= 25 : 5
= 5 : 1
Area or rectangle EFGH = 875 ft²
the area in square feet is 4400. (because to find the area of the rectangle you multiply the 2 side lengths, 100 and 80 which gives you 8000, then you find the area of the square, multiply 60 by 60 which is 3600, then you subtract the total area of the backyard by the area taken up by the garden, 8000-3600, which gives you your total of 4400.)
Here,
Volume of cylinder = 539^3 cm
Circumference = 22 cm
Height = ?
Now,
Circumference = 2πr
or, 22 = 2*22/7*r
or, 22 = 44/7*r
or, 154/44 = r
◆ r = 3.5 cm
Then,
Volume of cylinder = πr^2h
or, 539 = 22/7*(3.5)^2*h
or, 539 = 22/7*12.25*h
or, 539 = 269.5/7*h
or, 3773 = 269.5*h
or, 3773/269.5 = h
◆ h = 14 cm

Answer:
Step-by-step explanation:
f(x) = x⁵ – 8x⁴ + 16x³
As x approaches +∞, the highest term, x⁵, approaches +∞.
As x approaches -∞, x⁵ approaches -∞ (a negative number raised to an odd exponent is also negative).
Now let's factor:
f(x) = x³ (x² – 8x + 16)
f(x) = x³ (x – 4)²
f(x) has roots at x=0 and x=4. x=4 is a repeated root (because it's squared), so the graph touches the x-axis but does not cross at x=4.
The graph crosses the x-axis at x=0.
If the original investment doubled in 10 years, then double the investment
will double again in the next 10 years. Thus, in <u>20 years</u>, the original sum
would have increased fourfold.
