Find the 46th term.

Answer: D (82, 84, 90, 80, 74)

Finding Range:

To find range, you must subtract the smallest number to the highest number in that number pattern.

For example, the highest in D is 90, and the smallest is 74. 90-74 is 16, which matches the range for a possible price (16 = 16).

Range is basically the most easiest to find out of median, mean, and mode. You just have to find the greatest-smallest = range.

Finding Mean:

To find mean, you must add all the numbers up then divide the sum by the QUANTITIY of all the numbers.  

For example, if we add 82, 84, 90, 80, and 74, we would get 410. Since there are 5 numbers that make up 410, we divide 410 by 5, and therefore getting 82. This matches the mean of the price of a textbook (82 = 82).

Mean is basically easy to find as you just add all the numbers and divide it by how much numbers make that sum.

Conclusion:

In conclusion, the mean and range all match a possible price of the textbook, having a range of $16 and a mean of $82. Thus, D is the right answer.

The correct option is D (82, 84, 90, 74)

Range is subtract the smallest number to the highest number in that number pattern.

Mean is addition of all the numbers up then divide the sum by the quantities of all the numbers.  

The highest in D is 90, and the smallest is 74. 90-74 is 16, which matches the range for a possible price (16 = 16).

Addition of 82, 84, 90, 80, and 74, we would get 410. Since there are 5 numbers that make up 410, we divide 410 by 5, and therefore getting 82. This matches the mean of the price of a textbook (82 = 82).

Therefore, the possible prices for the textbook is the possible prices for the textbook is  (82, 84, 90, 74).

"A solid sphere is cut into 12 equal wedges. The volume of each wedge is V= 4/3πr³. Solve the formula for r."

A solid sphere is cut into 12 equal wedges. The volume of each wedge is V= 4/3πr³. The value of r is (9V/π)^1/3.

It is given that;

The  Volume of a sphere = V = 4/3πr³

Dividing into 12

4/3 x 1/12 πr³ = 1/9πr³

V = 1/9πr³

Cross multiply

9V = πr³

Divide both sides by π

9V/ π = πr³/ π

9V/ π = r³

Take the cube root of both sides

r = (9V/π)^1/3

Thus, The value of r is (9V/π)^1/3.

Answer:

Second option

Step-by-step explanation:

Given the following question:

We are given four choices and we need to determine which choice is a rational number. In order for any integer to be a rational number you have to be able to write it as a fraction.

In this case, options one and four are immediately excluded since they are repeating decimals. They cannot be written as a fraction which leaves us with the second option or the third option.

We will see that f'(x) > 0, which means that f(x) is an increasing function.

For any function f(x), if f'(x) > 0, then f(x) is increasing for any value of x.

Here we have the cubic function:

f(x) = x³ + 4x

If we differentiate this, we get:

f'(x) = df(x)/dx = 3x² + 4.

And notice that x² is always positive, then f'(x) > 0, which means that f(x) is an increasing function.

Answer:

The answer is D = 9/57

Step-by-step explanation:

Get the variable D by itself as stated to solve for D.

I got the other numbers to the other side.

70D + 6 - 9D = 35 + 4D - 20.

(70D - 9D - 4D) = (35 - 20 - 6)

57D = 9

D = 9/57

The liters of smoothies sold is 9 7/8 liters.

An equation is a statement formed when two algebraic expressions are equated by an equal sign.

The volunteer prepares 12 1/2 = 25/2 liters of smoothies

The remaining amount of smoothies is 2 5/8 = 21/8 liters of smoothies

Let the amount of smoothies sold is x liters

Then the equation formed to determine the value of x is

x = (25/2) - (21/8)

x = 79/8

x = 9 7/8 liters

Therefore, the liters of smoothies sold is 9 7/8 liters.

The parametric equation that represents the same path as the original equation is x = 3 + cos(2θ) and y = 2sin(2θ).

The given parametric equation can be expressed as follows;

x = 3 + cosθ

y = 2sinθ

From the given options, a plot of the various equation can be used to determine the paths of the equation.

For; x = 3 + cos(2θ) and y = 2sin(2θ), its parametric plots is same as original equation since the equation [3 + cos(2θ) and y = 2sin(2θ)] changed at equal rate of the angles.
