Step-by-step explanation:

Prius' acceleration

  60 mi/hr = 88 ft s

accel = change  in v / change in time =  88 f/s  / 10.3 s = 8.54 ft / s^2

F = ma     =    2903 * 8.54 = 24802  lb ft/s^2

Now increase the mass to 4903 by adding a 2000 lb trailer  (which, by the way is way past the towing capacity of an anemic Prius !)

    F = ma

   24802 = 4903 a    shows a = 5.06 ft/s^2

  45 mi/hr = 66 ft/s

      a = change in v / change in time

      5.06 = 66 / 5.06 = 13 sec

Step-by-step explanation:

8x + 6 = 50

subtract 6 from each side:

8x +6 (-6) = 50 (-6)

8x=44

divide by 8:

8x/8=44/8

x=5.5

round to single shirts:

x=5 shirts

Answer:

Step-by-step explanation: you have to divide 50 by 8 then get your answer of 6.25, but you also have to consider two things; the extra $6.00 flat fee, and you cant buy 6.25 shirts, so what we do is multiply 8 times 6 to get 48, but we have to consider the extra $6.00, so you take away 8 which gives you 5 shirts, plus the shipping fee so in all he can buy 5 shirts.

1) Let's sketch this out so that we can better understand it

2) Reminding ourselves of the metric relations of a right triangle we can write out the following:

Note that the radius intersects that chord with a 90º angle so it bisects that chord.

She invested $2,400 in the 2.5% account and $3,600 in the 4% simple interest account

Here, we want to know the amount of money invested in each account

Let the amount invested in the 4% simple interest account be $x ----> (a)

While the amount invested in the 2.5% account be $y -------->(b)

So mathematically;

Both the interests are added to get total interest

x + y = 6,000 ••••••(i)

Let’s now evaluate the interest

for the 4% account , interest = 4/100 * x = 4x/100

For the 2.5% account, interest = 2.5/100 * y= 2.5y/100

The addition of both  interests gives the total simple interest;

4x/100 + 2.5y/100 = 204

Multiply through by 100

4x + 2.5y = 20,400 •••••••(ii)

From i, x = 6,000 - y

Putting this into equation ii

4(6,000-y) + 2.5y = 20,400

24,000 - 4y + 2.5y = 20,400

24,000-20,400 = 4y - 2.5y

1.5y = 3,600

y = 3,600/1.5

y = $2,400

Recalling it again,

x = 6000 - y

x = 6,000 - 2,400

x = $3,600

Therefore, Nina invested $2,400 in the 2.5% account and $3,600 in the 4% simple interest account

The exponents are solved below\

What are exponents?

Exponentiation is a mathematical process denoted by the symbol bn that involves two integers, the base b and the exponent or power n, and is spoken as "b (raised) to the (power of) n." Exponentiation corresponds to repeated multiplication of the base when n is a positive integer: bn is the product of multiplying n bases. Typically, the exponent is displayed as a superscript to the right of the base. In such scenario, bn is referred to as "b raised to the nth power," "b (raised) to the power of n," "the nth power of b," "b to the nth power," or, more succinctly, "b to nth." In other words, when a base raised to one exponent is multiplied by the same base raised to another exponent, the exponents accumulate.

The exponents are solved as follows

(10⁻²)⁹ = 10⁻¹⁸ = 1/10¹⁸

10⁻³ - 10⁻⁸ = 1/10³ - 1/10⁸ = (10⁵ - 10⁸)/10⁸ = 9.9999x10⁻⁴

Answer:

The biker's pace is 25 miles per hour and the walker's speed is 50/3 miles per hour.

Answer:The speed of the walker is 16.67 miles per hour.

The speed of the cyclist is 25 miles per hour.

How to calculate the value?

Let the speed of a walker = x

Biker's speed = 1.5x

Their relative speed will be:

= 1.5x - x = 0.5x

Distance between them = 12.5 miles

Time taken = 1.5 hours.

It should be noted that distance will be:

= Speed × Time

12.5 = 1.5 × 0.5x

Divide through to get x

12.5 = 0.75x

x = 16.67 miles per hour.

Speed of cyclist = 16.67 × 1.5 = 25 miles per hour.

The expression for volume is (28-2x)(22-2x)x and when x=6, the volume is 840 inch^3.

A 3D object's volume is the amount of actual space it occupies. It is a 2D shape's 3D equivalent of area. It is quantified in cubic units like cm3. It means that the amount of space a closed form can occupy in three dimensions depends on its volume. Volume is a gauge of a thing's potential. For instance, a cup is said to have a 100 ml capacity if the brim can hold 100 ml of water. Another way to measure volume is the amount of space a three-dimensional item takes up.

According to question,

Answer:

y = 6m - 13

Step-by-step explanation:

Parallel lines have the same slope.  The slope in the equation y = 6x -2 is 6.

To write an equation in the slope intercept form, we need a slope and a y-intercept.  We have the slope, we need to find the y-intercept.

To find the y intercept, we need a slope, and x on the line and a y on the line.  The point (3,5) gives us the x and the y.

slope = 6

x = 3

y = 5

y = mx + b  plug in what we know and solve for b

5 = 6(3) + b

5 = 18 + b  Subtract 18 from both sides of the equation

-13 = b

y = mx  + b

y = 6m - 13

As per the terms from the two sequences given in tables as attachment hereby along with the question statement, the following statements from the provided options are true.

(i) [(a₁) > (g₂)]

(iv) Initially (aₙ) is greater than (gₙ), and as "n" gets larger, (gₙ) is greater than (aₙ).

As per the question statement and the reference tables attached thereby along with the question, we are provided with terms from the two sequences in table format, and five statements based on the sequences.

We are required to determine which statements among the five, are true.

To solve this question, we will use the trial-and-error method, where we will consider individual statement and assess it's honesty.

First statement is [(a₁) > (g₂)], which is true. As we can see from the table, that, [(a₁) = 10] and [(g₂) = 4], i.e., (10 > 4), or, [(a₁) > (g₂)].

Second statement is that, "The constant difference for (aₙ) is 10" which is False. We can clearly see from the table that, (a₁ = 10), (a₂ = 15), (a₃ = 20), (a₄ = 25) and so on, and [(25 - 20) = (20 - 15) = (15 - 10) = 5], i.e.,

[(a₄ - a₃) = (a₃ - a₂) = (a₂ - a₁) = 5]. Hence, the common difference for (aₙ) is 5, and not 10.

Third statement is that, "(aₙ) can be modelled by a linear function, and (gₙ) can be modelled by an exponential function" which is true for the first part, but false for the second, making the complete statement false as whole.
From the left hand side table, we can see that, (a₂ = 15) and (a₁ = 10),

Or, [a₂ = (10 + 5)]

Or, [a₂ = (a₁ + 5)]

Similarly, (a₃ = 20),

Or, [a₃ = (15 + 5)]

Or, [a₃ = (a₂ + 5)]

That is, we can generalise (aₙ) as

[aₙ = {(aₙ₋₁) + 5}] where, (n = 2, 3, 4, 5...) and (a₁ = 10).

Hence, (aₙ) can be modelled by a linear function.

But from the right hand side table, we can see that, (g₂ = 4) and (g₁ = 2),

Or, [g₂ = (2 * 2)]

Or, [g₂ = 2g₁]

Similarly, (g₃ = 8),

Or, [g3 = (2 * 4)]

Or, [g₃ = 2g₂], it goes on for (gₙ).

Therefore, we can generalise (gₙ) as

[gₙ = 2*(gₙ₋₁)] where, (n = 2, 3, 4, 5...) and (g₁ = 2).

Here, (gₙ) can also modelled as a linear function and not as a exponential function (which goes in the form of "xⁿ").

Coming to the fourth statement, "Initially (aₙ) is greater than (gₙ), and as "n" gets larger, (gₙ) is greater than (aₙ)" is true, as from both the tables,

For (n = 5), [aₙ = a₅ = (a₄ + 5) = (25 + 5) = 30],

And [gₙ = g₅ = (2 * g₄) = (2 * 16) = 32], which is greater than 30,

Or, [(g₅) > (a₅)].

Similarly, for (n = 6), (a₆ = 35) while (g₆ = 64), i.e., [(g₆) > (a₆)], and it continues for greater values of "n".

Coming to the last statement, that [a₁₀ > g₆], is false. As we can observe from the both the tables and their sequence,

For (n = 5), (aₙ = 50), for (n = 6), (aₙ = 35), for (n = 7), (aₙ = 40), for (n = 8), (aₙ = 45), for (n = 9), (aₙ = 50) and for (n = 10), (aₙ = 55),

While on the other hand, for (n = 5), (gₙ = 32) and for (n = 6), (gₙ = 64).

Since (64 > 55), therefore, [(g₆) > (a₁₀)].
