A word is put between to and the verb while splitting an  infinitive. In terms of grammar, splitting an infinitive is acceptable.

In other cases, it might even be more logical to do so. An infinitive is a verb's to form, such as "to go" or "to be."

When it is said that infinitives should never be split, it means an adverb should never come before the verb in the sentence "to confidently proceed."

As we know  split infinitive is one in which the word "to" and the verb in the base (infinitive) form of the verb are separated by one or more words.

Adverbs are the words that split infinitives the most frequently.

If the radius of the base of a cone is decreasing at rate of 2 cm/minute and the height is kept constant at 9 cm, the rate of change of the volume at radius 13 cm is 489.4 cm³/minute

To calculate the rate of change, we need to take the derivative of the variables with respect to time.

The volume of a cone is given by:

V = 1/3 . πr²h

Where:

r = radius of the base

h = height

Since the height of the cone is held constant, then the derivative with respect to time is:

dV/dt = 1/3 h. 2πr dr/dt

Parameters given:

dr/dt = 2 cm/minute

h = 9 cm

r = 13 cm

Hence,

dV/dt = 1/3 x 9 x 2π x 13 x 2

dV/dt = 489.4 cm³/minute

Hence, at radius 13 cm, the rate of change of the volume is 489.4 cm³/minute

It looks like there was typos in your question, most probably your question was:

Bonnie bought more jolly because the weight of her 2 bags is more than that of Linsey.

The pound or pound-mass is a unit of mass used in British imperial and United States customary systems of measurement.

If each Linsey's bag of jolly weighs 18 ounces then 3 bags would weigh 18 x 3 = 54 ounces

If each Bonnie's bag of jolly weighs 2 pounds then the 2 bags would weigh 2 x 2 = 4 pounds.

converting 4 pounds to ounces at the rate of 16 ounces per pound we have 16 x 4 = 64 ounces

So Bonnie bought more jolly than Linsey as the weight of the bags of Bonnie is heavier than that of Linsey.

In conclusion Bonnie bought more than Linsey as the weight of bags of Bonnie outweighs Linsey's

The expected area of a random square which has a side length that is uniform random variable is 1/3.

A family of symmetric probability distributions includes the continuous uniform distribution and rectangular distribution. The distribution describes an experiment with a random result that falls within predetermined bounds.

 The parameters, a and b, which represent the minimum and maximum values, define the bounds. The interval may be closed (for example, [a, b]) or open (for example, (a, b)). common abbreviation for the distribution is U (a, b), where U stands for uniform distribution. 

The length of the interval is defined by the difference between the bounds; intervals with the same length on the distribution's support are equally likely.

Let, side of the square = X

we know that the area of a square = side × side

                                                          =  X  ×  X

                                                          =  X^{2}

now, by using Continuous uniform distribution,

E[ X^{2} ] =  [tex]\int\limits^1_0 X^{2} \, dx[/tex]    

                =  [tex][\frac{1^{3} }{3} - \frac{0^{3} }{3} ][/tex]

                =  [tex]\frac{1}{3}[/tex]

What is pythagora's theorem?

In ΔABC

AC² = AB² - BC² (∴Pythagoras theorem)

AC = √25² - 7²

AC = √625 - 49

AC = √576

AC = 24 feet

As after sliping length of ladder remains same ⇒ DE = 25 feet and feet 4 feet.

Let say x be the length of how much the ladder slips.

New height = DC = AC - AD = 20 feet

EC = (x + 7 ) feet

In ΔDEC,

DE² = DC² + EC²  (∴Pythagoras theorem)

25² = 20² + (x + 7)²

Closure property states that when a set of numbers is closed beneath any arithmetic operation such as subtraction, addition, division, and multiplication and is performed on any two numbers of the set with the reply being another number from the set itself. When including polynomials, the factors and their exponents don't alter. As it were their coefficients will possibly alter.

The equation that Amy can use to find how many games of Balloon Bouncer, g, she played is; g = (35 - 2a)/3

We are told that Amy used her first 2 tokens at Glimmer Arcade to play a game of Roll-and-Score.

Balloon Bouncer costs 3 tokens per game, and Amy started with a bucket of 35 game tokens.

Thus, the expression for the number of balloon bouncer games played at the arcade is :

2a + 3g = 35

Let :

Glimmer arcade, a = $2 per game

Balloon bouncer, g = $3 per game

Total game tokens = 35

Her spending could be represented using the expression :

2a + 3g = 35  

g = number of balloon bouncer games played

It is discovered that the (1) graph represents a function whose inverse is also a function using the concept of an inverse function.

The set of ordered pairs is the graph of a function f in mathematics, where these pairs are Cartesian coordinates of points in two-dimensional space and so form a subset of this plane in the typical situation when x and f(x) are real integers.

To develop a graph is to make a diagram that depicts the relationship between two or more objects.

Make a sequence of bars on graph paper as an example of a graph.

Since there is only one value of x in the first graph for any value of y, the inverse is also a function, making this the right answer.

The inverse is not a function in the second graph since, for instance, y = 0 when x = -1 and when x = 1.

For instance, in the third graph, the inverse is not a function because y = -3 when x = 0 and x = 2.

For instance, in the fourth graph, y = 1 for two different values of x, proving that the inverse is not a function.

Therefore, it is discovered that the (1) graph represents a function whose inverse is also a function using the concept of an inverse function.

Answer: c = -14 over 3 (c = -14/3)

Step-by-step explanation:

1. Distribute: 5c + 4 = 2(c - 5) --> 5c + 4 = 2c - 10

2. Subtract 4 From Both Sides: 5c + 4 = 2c - 10 --> 5c + 4 - 4 = 2c - 10 - 4

3. Simplify: 5c = 2c - 14

4. Subtract 2c From both sides: 5c = 2c - 14 --> 5c - 2c = 2c - 14 - 2c

5. Simplify: 3c = 14

6. Divide Both Sides By The Same Factor: 3c divided by 3 = -14 divided by 3

7. Simplify: c = -14 over 3

Two ways in which the combination can be represented = 720 , 46656

A combination in mathematics is a choice made from a group of separate elements where the order of the selection is irrelevant.

According to the given information

Whether you can repeat numbers or not will determine which of two possibilities

First Way

If you cannot repeat the digits  

Then

You might perform 6 ! or 6x5x4x3x2x1 = 720

This is so that the initial digit, which can have up to six numbers, can never be repeated. As a result, one digit cannot be repeated, therefore

6 - 1 = 5. The third digit is the same, but since you've already used two of the six digits, you can only have 4.

The alternative

If you're able to repeat :

either [tex]6^{6}[/tex] or 6x6x6x6x6

= 46,656

This is due to the fact that each digit has six possible values.
