The expression which defines the nth term of the given sequence, in terms of n as required in the task content is; T (n) = 1 + 7(n - 1).

It follows from the task content that the expression which represents the nth term of the given sequence be determined.

According to the task content, the first term, a of the sequence is; 1.

Also, since; 8 - 1 = 15 - 8 = 22 - 15 = 29 - 22 = Common difference, d = 7.

Consequently, the required expression is an arithmetic sequence which can be modelled by;

T (n) = a + d (n - 1)

Since the constant common difference of consecutive terms in the sequence is; 7,

Ultimately, The required expression for the nth term of the expression is;

nth = 1 + 7(n -1)

On this note, the nth term of the arithmetic sequence is given by the expression; T (n) = 1 + 7 (n -1).

Answer:

  c  The first two hours cost $4, between two hours and six hours cost $2 per hour, and all hours after that cost $1.

Step-by-step explanation:

You want an interpretation of the graph that is a constant 4 up to x=2, has a slope of 2 for 2 ≤ x < 6, and a slope of 1 for x ≥ 6. The vertical axis is labeled dollars, and the horizontal axis is labeled hours.

The constant value of y = 4 for x < 2 means the cost of parking is $4 for the first two hours.

The slope of 2 from x=2 to x=6 means the cost of parking is $2 per hour between 2 and 6 hours.

The slope of 2 for x ≥ 6 means the cost of parking is $1 per hour for more than 6 hours.

The description of c applies.

__

Additional comment

The slope, or "unit rate", is the ratio of "rise" to "run". It can be simpler to choose a "run" of 1 and look at the corresponding "rise".

From x=2 to x=3, the cost rises from $4 to $6, a rise of 2 for the run of 1. That is why we say the slope is 2, or the "unit rate" in dollars per hour is $2 per hour.

The mathematical model that gives the stopping distance d in terms of speed v is

d = 1/(40 x 5280²) v²

The stopping distance when v is 59 miles per hour is 87.03 feet.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

The stopping distance d is directly proportional to the square of the speed v.

This can be written as,

d ∝ v²

Now,

Converting 40 miles into feet.

1 mile = 5280 feet

40 miles = 40 x  5280 feet

40 miles = 211200 feet

Now,

40 feet ∝ 211200 feet per

Now,

The stopping distance is 40 feet when the speed is 40 miles per hour

d = 40 and v = (40 x 5280) feet per hour

d = k v²

k = d/v²

k = 40/(40 x 5280)²

k = 1/(40 x 5280²)

The mathematical model that gives the stopping distance d in terms of speed v is

d = 1/(40 x 5280²) v²

The stopping distance when v is 59 miles per hour

v = (59 x 5280) feet per hour

d = 1/(40 x 5280²) x (59 x 5280)²

d = (59 x 59) / 40

child admission (c)= $5.70

adult admission (a)= $9.80

5.70c + 9.80a = 912.20      (i)

a + c = 114                            (ii)

Set up the equation:

Answer:

When the plane is 2mi away from the radar station, its distance's increase rate is approximately 433mi/h.

Step-by-step explanation:

Sketch a right triangle with one leg going vertically a length of 3 miles above the station, and the other leg x going horizontally from the top of the first leg. Distance r from plane to station is related by r2 = x2 + 32. Differentiate: 2r dr/dt = 2x dx/dt, which rearranges to the desired dr/dt = x/r dx/dt. When r = 4, x2 = 42 - 9 and x = √7. So dr/dt = (√7 / 4) * 520 mph = 344 mph.

The value of [tex]\angle[/tex]ABC=6° was found with the help of the law of cosines.

What is the law of cosines of a triangle?

The lengths of a triangle's sides are correlated with the cosine of one of its angles according to the law of cosines. We can now determine values for distances and angles that are impossible to measure without the aid of trigonometry. When calculating the third side of a triangle given two sides and their enclosed angle, as well as when calculating the angles of a triangle if we know all three sides, the law of cosines is used.

Given values are AB = c = 36 units, BC = a = 42 units, and [tex]\angle[/tex]BCA = 31°.

Now let AB = b, we find b using the law of cosines and quadratic equation:

[tex]c^2 = a^2 + b^2 - 2a b \cos C \\36^2 = 42^2 + b^2 - 2 \cdot \ 42 \cdot \ b \cdot \ \cos 31\degree \\ b > 0 \\ b = 7.22[/tex]

Now, we calculate [tex]\angle[/tex]ABC using the law of cosines:

[tex]\angle ABC=arc cos(\frac{a^{2}+c^{2}-b^{2} }{2ac}) \\\angle ABC=arc cos(\frac{42^{2}+36^{2}-7.22^{2} }{2.42.36}) \\\angle ABC=5.55[/tex]

Answer:

Maria can buy at most 2 bottles of cranberry juice and 7 lemon-lime soda bottles.

Step-by-step explanation:

For this problem, we can set up an algebraic expression to represent the price, and this will help us solve the problem.

So firstly, let's assign the number of cranberry juice bottles to the variable  "C". We could technically represent this as the variable name "cranberry juice bottles", but "C" is a bit more easier to write when writing an algebraic expression while still making it easy to distinguish. Let's also assign the number of lemon-lime soda to the variable "L".

Now let's find a way to express the price of each. The price of buying a certain amount of items, can generally be expressed as: [tex](\text{items bought})*(\text{item price})[/tex], since you have to pay the item price for each item bought, also known as, multiplication.

Since we know that the price of a cranberry juice bottle is $3.80 then that means the total amount used towards cranberry juice can be expressed as: [tex]3.80C[/tex]. We're just multiplying the number of cranberry juice bottles times the price. Likewise, we can represent the total amount used towards lemon-lime soda as: [tex]1.40L[/tex]. The same logic is being applied here.

Now if we add both of these, we get the total amount that will be spent which is: [tex]3.80C + 1.40L = T[/tex], and in this case I just set it equal to "T" which just represents the total spent.

Now there's two more things to do. Generally we can't really solve two-variable equations and we want to express one variable in terms of the other, so that we can rewrite the equation as a one-variable equation.

There is one piece of information given that allows us to do this. "The recipe calls for 3.5 times as many bottles of lemon-lime soda as cranberry". So we can represent the numbers of lemon-lime soda bottles as 3.5 times the amount of cranberry juice bottles. We can express it as: [tex]L=3.5C[/tex]

So now let's plug this into the equation, instead of "L". This gives us: [tex]3.80C + 1.40(3.5C) = T[/tex]

let's multiply the 1.40 by the 3

[tex]3.80C + 4.9C= T[/tex]

now let's add up the values.

[tex]8.7C=T[/tex]

Now lastly, this represents the total amount that is going to be spent. Since Maria only has $17.40, we want this total to be less than or equal to 17.40 (assuming there is no sales tax, but this was never given). this gives us our final expression we will be using: [tex]8.7C\le 17.40[/tex]

From here solving the problem is actually pretty easy. Think of the inequality as a linear equation, we can still apply the same (for the most part) algebraic manipulations we apply to linear equations. We just divide both sides by 8.7 to isolate the C

[tex]\frac{8.7C}{8.7}\le\frac{17.40}{8.7}\\\\C\le 2[/tex]

So Maria can buy a maximum of 2 bottles of cranberry juice. From this we can actually determine the number of lemon-lime soda bottles.

So we know that:

[tex]C=2[/tex]

From this we can determine what L is, since remember the equation we set up earlier?

[tex]L = 3.5C[/tex]

Let's just plug C into the equation, and we get:

[tex]L=3.5(2)[/tex]

Multiply

[tex]L=7[/tex]

So Maria can buy at most 2 bottles of cranberry juice and 7 lemon-lime soda bottles.

What is the Basic Proportionality Theorem?

The basic Proportionality Theorem (can be abbreviated as BPT) states that, if a line is parallel to a side of a triangle that intersects the other sides into two distinct points, then the line divides those sides in proportion.

In the given figure side TU is parallel to side LK

If JK = 64 and JU = -4 + 4x

then UK = JK - JU

              = 64 - (-4 + 4x)

               =68 - 4x

Similarly,if JL = 72 and JT = 27

then TL = JL - JT

             = 72 - 27

             = 45

Now by using the property of the basic proportionality theorem, we can write

              [tex]\frac{JT}{TL} =\frac{JU}{UK}\\\\ \frac{27}{45} =\frac{-4+4x}{68 - 4x}\\\\\frac{3}{5} = \frac{-4+4x}{68 - 4x}\\\\3(68-4x) = 5(-4+4x)\\\\204 - 12x=-20+2x\\\\204+20=14x\\\\x=\frac{224}{14}\\\\x=16[/tex]

Now we can calculate the length of JU = -4 + 4x

                                                                 = -4 + 4(16)

                                                                 = -4 + 64 = 60

Hence, the length of the JU would be 60 units.
