By substituting x = 2 into the function f(x) = 2(x)² + 5√(x + 2) and simplifying the equation, the resulting value of f(2) is calculated to be 18.
For the given function f(x) = 2(x)² + 5√(x + 2), we are asked to find the value of f(2). To find this, first substitute x = 2 into the function. So, the calculation becomes
f(2) = 2 * (2)² + 5 * √(2 + 2)
simplifying this equation, we get:
f(2) = 2 * 4 + 5 * √4 = 8 + 5 * 2 = 8 + 10 = 18
So, f(2) = 18

Answer:
The volume of sphere is:
65.4167 yd^3
Step-by-step explanation:
We are given surface area of sphere as:
We know that the surface area of sphere of radius ''r'' is given by the formula:
i.e. we have:
As we know that the radius of a circle can't be negative.
Hence,
Now the volume of sphere is given by:
Volume of sphere is:
65.4167 yd^3
In this case, 40 hectograms is equal to 4000 grams.
To convert hectograms to grams, we need to know that 1 hectogram (hg) is equal to 100 grams (g).
Now, let's calculate the number of grams in 40 hectograms:
1 hectogram = 100 grams
Therefore, 40 hectograms will be:
40 hectograms = 40 * 100 grams
40 hectograms = 4000 grams
So, there are 4000 grams in 40 hectograms.
In summary, to convert hectograms to grams, we use the conversion factor of 1 hectogram = 100 grams. By multiplying the number of hectograms by 100, we get the equivalent weight in grams. In this case, 40 hectograms is equal to 4000 grams. This conversion is based on the metric system, where prefixes like hecto- and kilo- represent multiples of 100 and 1000, respectively, making it easy to convert between different units of weight.

Answer:
The volume of the cylinder would be 392.5 cubic centimeters (B)
Step-by-step explanation:
To find the volume of the cylinder, we will need to use the formula:
V = πr^2h
Since the value of the radius is always equal to r = d/2 we can just divide the diameter by 2. We can then plug in our values from the equation into the formula, so our new formula is now:
V = (3.14)(5)^2(5)
Following the order of opperations EMDAS, we start with exponents:
V = (3.14)(25)(5)
Then we move on to multiplication, going from the left side to the right:
V = (78.5)(5)
V = (392.5)
We now know that the volume of the cylinder is equal to 392.5 cubic centimeters.
Answer:
The formula for the volume of a cylinder is V = πr²h where r is the radius of the base of the cylinder and h is its height. Since the diameter of the cylinder is 10 cm, its radius is 5 cm. Substituting these values into the formula gives:
V = π(5)²(5) = 78.54 cm³
Rounding to the nearest hundredth gives 78.54 cm³ ≈ 78.5 cm³.
Therefore, the volume of the cylinder is approximately 78.5 cm³.
