Answer:
1.38 to the nearest hundredth.
Step-by-step explanation:
Dividing:
x + 1 ) 3x - 1 ( 3
3x + 3
-4
so (3x - 1) / (x + 1) = 3 - 4 / x+ 1
Integral of (3 - 4 / x+1 ) = 3x - 4 ln(x + 1)
Between limits of 1 and 2 we have:
(3(2) - 4 ln 3) - (3 - 4 ln2)
= 1.6056 - 0.2274
= 1.3782.
Answer:

Step-by-step explanation:
Answer:
15°C
Step-by-step explanation:
Use the following formula to convert Fahrenheit to Celsius:
Substitute the value for the variable and solve for C.
Therefore, 59°F is equivalent to 15°C.
the ratios are ratio proportional
Answer:
Step-by-step explanation:
To start the problem, you recognize that the figure is a cone with a radius of 21 ft and a height if 12 ft.
Then, you consult your list of volume formulas to find the one for the volume of a cone. It is ...
V = (1/3)πr²h . . . . . where r is the radius and h is the height
Fill in the given numbers and do the arithmetic.
V = (1/3)π(21 ft)²(12 ft) = 1764π ft³ ≈ 5542 ft³
___
If your calculator does not have a button for π, you can use 3.14159. Most spreadsheets will have a PI() function that will give this value.
