What is the approximate volume of a cone with a height of 12 in. and radius of 9 in.?

1 answer:

8 0

Volume of the cone = 1/3π r^2 h
So, we are given that r = 9 and h = 12
plugging in all the known values
1/3 * (3.14) * 9 * 9 * 12
= 1017.36 cm³
or
≈1017.4 cm³

Which of the following options results in a graph that shows exponential growth?

atroni [7]

Answer:

f(x) = 0.4·3^x

Step-by-step explanation:

Exponential growth occurs when the base is greater than 1 and the exponent is an increasing non-negative function of the variable, or when the problem can be cast in that form using the rules of exponents.

Here, in f(x) = 0.4×3^x, the base is 3 (greater than 1), and the exponent of x has a positive coefficient.

At what temperature would the centigrade and Kelvin scales give similar readings

Serjik [45]

Answer:

The formulas for converting between degree Celsius and degree Fahrenheit are:

°F = (°C * 9/5) + 32

°C = (°F - 32) * 5/9

To find the temperature when both are equal, we use an old algebra trick and just set ºF = ºC and solve one of the equations.

°C = (°C * 9/5) + 32

°C - (°C * 9/5) = 32

-4/5 * °C = 32

°C = -32 * 5/4

°C = -40

°F = (°F * 9/5) + 32

°F - (°F * 9/5) = 32

-4/5 * °F = 32

°F = -32 * 5/4

°F = -40

So the temperature when both the Celsius and Fahrenheit scales are the same is -40 degrees

yan [13]

Answer:

There was a 50% chance that the goldfish would swim to the left

$\textsf{one in two}=\sf \dfrac{1}{2}=\sf \dfrac{1\times 50}{2 \times 50}=\dfrac{50}{100}=50\%$

Newspaper headline:

There was a 50% chance that the goldfish would swim to the left.
