The sequence is will always have even numbers, is hence proved.

Given, the quadratic sequence is: 44:52:64:80

Sequences with a term are known as quadratic sequences. They can be distinguished by the fact that the first differences between terms are not equal but the second differences between terms are. Utilizing the term sum in an arithmetic progression formula, the sum of even numbers formula is achieved. The equation is Sum of Even Numbers Formula = n(n+1), where n is the total number of terms in the series.

The formula is: Tₙ = 2n² ₊ 2n  ₊ 40

take 2 common

Tₙ = 2(n² ₊ n  ₊ 20)

in other words n² ₊ n  ₊ 20  = y

therefore , Tₙ = 2y

which by definition makes Tₙ an even number at all times.

Step-by-step explanation:

Given,

No. of cameras that Gretta has : 103

No. of Cameras she misplaced : 75

1 full box contains 1 camera each

No. of full boxes that she can ship:

= No. of Cameras she has - no. of cameras she misplaced.

= 103-75

= 28

Therefore, the no. of full boxes that Gretta can ship is 28.

Answer:

1.2 miles.

Step-by-step explanation:

because her weight is similar to that of a teenaged girl, she wouldn't be able to pedal very hard, or for long periods of time- she doesn't have the stamina for a cross-country ride. Therefore, using various statistics on house location in relation to park location, we can assume that the distance is about 1.2 miles.

The amount of force on the grain of rice is 23.52 × 10⁻⁵ newtons.

The right format for scientific notation is a × 10ᵇ, where an is an integer or decimal number with an absolute value more than or equal to one and less than ten, or 1 < |a| < 10. For the scientific notation to be mathematically equivalent to the original value, b must be a power of 10.

The Force of a particle is given as:

F = ma, where m is the mass and a is the acceleration.

Now, the mass of a grain of rice is 2.4 × 10⁻⁵ kg.

The acceleration due to gravity is 9.8 m/s².

Therefore, the force on the grain of rice is :

F = ma

F = 2.4 × 10⁻⁵ kg × 9.8 m/s²

F = 23.52 × 10⁻⁵ newtons

[tex]\displaystyle{h = \dfrac{3V}{\pi r^2}}[/tex]

Step-by-step explanation:

Given the equation of:

[tex]\displaystyle{V=\dfrac{1}{3}\pi r^2 h}[/tex]

The equation is also reference to volume of a cone. To solve an equation for h-term, we’ll multiply both sides by 3 first to clear all denominator:

[tex]\displaystyle{V \cdot 3 = \dfrac{1}{3}\pi r^2 h \cdot 3}\\\\\displaystyle{3V = \pi r^2 h}[/tex]

Then divide both sides by [tex]\displaystyle{\pi r^2}[/tex]:

Neptune is 7. 76 × 10^2 times farther than Mercury from the sun. Option B

A ratio can be defined as the comparison of two or more number indicating their sizes in relation to each other.

It also explains how any times a number contains another.

From the information given, we have;

To determine the distance Neptune is from the sum than Mercury, we divide the distance for Neptune by that of Mercury

= 4.5 x 10^10/  5.8 x 10^7

= 776. 86

Turn into scientific notation

18+7(n-3)

=======================================================

Explanation:

We can rewrite the right hand side of choice C like so

18+7(n-3)

18+7(n-1-2)

18+7(n-1)+7(-2)

18+7(n-1)-14

4+7(n-1)

Which is now in the form a+d(n-1)

This confirms choice C to be arithmetic. The other choices cannot be written in the format of a+d(n-1). Choices A and B are quadratic sequences while choice D is exponential.

The first few terms of choice C are: 4, 11, 18, 25, 32, ...

To get new terms, add 7 to the previous one.

-------------

Notice how if n = 5 for instance, then,

[tex]a_n = 4+7(n-1)\\\\a_5 = 4+7(5-1)\\\\a_5 = 32\\\\[/tex]

and

[tex]b_n = 18+7(n-3)\\\\b_5 = 18+7(5-3)\\\\b_5 = 32\\\\[/tex]

This confirms that [tex]a_n = b_n[/tex] when n = 5. I'll let you check other positive integer values for n.

Answer:

[tex]\textsf{c)} \quad s_n=18+7(n-3)[/tex]

Step-by-step explanation:

An arithmetic sequence has a constant difference between each term.

General formula of an arithmetic sequence

[tex]\boxed{s_n=a+(n-1)d}[/tex]

where:

When expanded, the formulas for answer options a and b will both contain an n² term, so we can immediately discount them since an arithmetic sequence is linear.

Similarly, we can also discount option d since this formula includes an exponential term and is therefore not linear.

Therefore, the only valid answer is option c.

To confirm, rewrite the formula for c in the general form for an arithmetic sequence:

[tex]\begin{aligned}\implies s_n&=18+7(n-3)\\s_n&=18+7n-21\\s_n&=7n-3\\s_n&=7n-7+4\\s_n&=7(n-1)+4\\s_n&=4+(n-1)7\end{aligned}[/tex]

Therefore, formula that defines an arithmetic sequence is:

Using probability we can say that the event that Gavin rolls an even number on a number cube is as likely as not.

Probability is the study of chance. The likely chance that an event can occur in a random experiment written as a fraction is called probability.

Probability of a event is calculated as the ratio of the favorable outcomes of an event to all the possible outcomes of the event.

Given as experiment: A number cube is rolled by Gavin.

Event : An even number comes up on the face of the cube.

Favorable outcomes : {2,4,6} = 3 outcomes

Total outcomes or sample space: {1,2,3,4,5,6} = 6 outcomes

Probability that an even number comes up:3/6=1/2

Probability that an even number does not come up=1-1/2=1/2

From the above probabilities we see that :

P(even)=P(not even)=1/2

Hence the Gavin rolls an even number is as likely as not likely.

The statement as an inequality expression is 739214 < x < 740000

Inequality expressions are mathematical statements that are represented by variables, coefficients and operators where the opposite sides are not equal

The statement is given as

"The number on Riben's ticket has a value between the values 739214 and 740000”

Let the value on the ticket be x

So, the statement can be represented as

"x has a value between the values 739214 and 740000”

"Between" means the values are exclusive

So, the statement can be represented as

739214 < x < 740000
