If a boat of initial value $25,500 depreciates linearly to a value of $23,000 in 4 years, then the rate of change of the boat's value is $625 per year.

Therefore, the answer is 625.

It is said that the boat depreciated linearly. So let us assume the depreciated value, y can be obtained by the linear equation y = mx + c, where x is the number of years passed and m the annual rate of change of the boat's value.

Value of Troy's boat initially in 2006 is $25,500 when he bought it. After 4 years, in 2010 the boat has a value of $23,000.

At x = 0, y = 25,500 and at x = 4, y = 23,000, that is

25,500 = m×0 + c

Implies c = 25,500

23,000 = m×4 + 25,500

m = - 2,500/ 4

m = - 625

Therefore y = 25,500 - 625x

Thus the annual rate of change of the boat's value is $625.

Answer:

The area of larger table is 24 square feet.

Step-by-step explanation:

Given are the length and width of small table

\(l_s = 2\ ft\\w_s = 3\ ft\)

The area of a rectangular table is calculated by multiplying the length and width. It is also given that the length and width of the larger table is double the length and width of small table

So the length and width of larger table will be:

\(l_l = 2*2 = 4\ feet\\w_l = 3*2 = 6\ feet\)

The area of larger table will be:

\(A_l = l_l*w_l\\= 4 * 6\\=24\ ft^2\)

Hence,

The area of larger table is 24 square feet.

Answer:

119 inches

Step-by-step explanation:

cos 42° = \(\frac{b}{160}\)

b = 160 × cos 42° ≈ 119 in.

The shape consist of a rectangle and a semi circle

The area of a rectangle is the product of its length and width while that of a semicircle pir^2

The radius of the semicircle is = 12/2

= 6 ft

The length and width of the rectangle are 16 ft and 12 ft respectively.

Hence the area of the shape

= 12 * 16 + 3.14 *6^2

= 192 + 113.04

= 305.04 sq ft

Answer:

a: 42 =  2*3*7

b: 31 = 31*1

c: 36 = 2*2*3*3

d: 45 = 3*3*5

Cada descomposición es unica.

Step-by-step explanation:

Sabemos que todo número entero puede ser reescrito como un producto de números primos.

Esta descomposición es única, dado que una vez tenemos un número escrito como producto de primos, esos números primos no pueden descomponerse en otra cosa, por lo que se concluye que una descomposición en primos es única.

a: 42

Para obtener la descomposición, podemos comenzar dividiendo por primos, comenzando por los más bajos.

En este caso, podemos comenzar por 2:

42/2 = 21

asi, podemos reescribir:

42 = 2*21

Ahora ya tenemos un factor que es primo, el 2, y un factor que no lo es, el 21.

Asi que debemos reescribir el 21 como producto de primos.

Y sabemos que 3*7 = 21, donde ambos 3 y 7 son primos, entonces:

42 = 2*21 = 2*3*7

42 = 2*3*7

así hemos reescrito 42 como un producto entre números primos.

b. 31

31 es un número primo, por lo que su descomposición es:

31 = 31*1

c. 36

Comenzamos dividiendo por 2.

36/2 = 18

36 = 2*18

Volvemos a dividir por 2 el 18.

18/2 = 9

18 = 2*9

reemplazando eso en nuestra descomposición obtenemos:

36 = 2*18 = 2*2*9

9 es impar así que no podemos dividir por 2, pasamos al próximo número primo, el 3.

9/3 = 3

9 = 3*3

Reemplazando eso, obtenemos:

36 = 2*2*3*3

d. 45

no podemos dividir por 2, puesto que es un número impar, así que pasamos al próximo primo, el 3.

45/3 = 15

45 = 3*15

Ahora descompongamos el 15.

15/3 = 5

15 = 3*5  (notar que 3 y 5 son primos)

Reemplazando eso, obtenemos:

45 = 3*15 = 3*3*5

45 = 3*3*5

the equation of the line tangent to f(x) = -2sin(x) at x = 34π is y = -2x + 68π + 2sin(34π).

To find the equation of the line tangent to the function f(x) = -2sin(x) at x = 34π, we need to find the slope of the tangent line at that point, and then use the point-slope form of the equation of a line.

The slope of the tangent line is equal to the derivative of the function at x = 34π. We can find the derivative of f(x) using the chain rule:

f'(x) = -2cos(x)

Therefore, f'(34π) = -2cos(34π) = -2.

This means that the slope of the tangent line is -2 at x = 34π.

To find the equation of the tangent line, we also need a point on the line. Since the tangent line passes through the point (34π, f(34π)), we can use this point as the point-slope form of the equation of the line:

y - f(34π) = m(x - 34π)

Substituting the values we have found, we get:

y - (-2sin(34π)) = -2(x - 34π)

Simplifying, we get:

y = -2x + 68π + 2sin(34π)

The diver's velocity during the first 2 sec of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

Given data: Initial velocity, u = 0 ft/sec

Acceleration, a = g = 32.2 ft/sec²

The maximum rate of fall, vmax = 80 mph

Time, t = 2 seconds

Air resistance constant, Ar = 0.2

We are supposed to determine the sky diver's velocity during the first 2 seconds of fall using the modified Euler method.

The governing equation for the velocity of the skydiver is given by the following:

ma = -m * g + k * v²

where, m = mass of the skydive

r, g = acceleration due to gravity, k = air resistance constant, and v = velocity of the skydiver.

The equation can be written as,

v' = -g + (k / m) * v²

Here, v' = dv/dt = acceleration

Hence, the modified Euler's formula for the velocity can be written as

v1 = v0 + h * v'0.5 * (v'0 + v'1)

where, v0 = 0 ft/sec, h = 2 sec, and v'0 = -g + (k / m) * v0² = -g = -32.2 ft/sec²

As the initial velocity of the skydiver is zero, we can write

v1 = 0 + 2 * (-32.2 + (0.2 / 68.956) * 0²)0.5 * (-32.2 + (-32.2 + (0.2 / 68.956) * 0.5² * (-32.2 + (-32.2 + (0.2 / 68.956) * 0²)))

v1 = 62.732 mph

Therefore, the skydiver's velocity during the first 2 seconds of fall using the modified Euler method with Ar= 0.2 is 62.732 mph.

The weight range within which the middle 95% of all miniature Tootsie Rolls will fall is approximately between 3.04 grams and 3.56 grams.

Since the weight of miniature Tootsie Rolls is normally distributed with a mean of 3.30 grams and a standard deviation of 0.13 grams, we can use the standard normal distribution to find the weight range within which the middle 95% of all miniature Tootsie Rolls will fall.

We need to find the z-scores that correspond to the middle 95% of the normal distribution. The area between the two z-scores will be 0.95. Using a standard normal distribution table or calculator, we can find that the z-scores that correspond to the middle 95% of the distribution are -1.96 and 1.96.

We can use the formula z = (x - μ) / σ to find the corresponding weight values for these z-scores. Substituting -1.96 for z and solving for x, we get:

-1.96 = (x - 3.30) / 0.13

x = 3.04

Similarly, substituting 1.96 for z and solving for x, we get:

1.96 = (x - 3.30) / 0.13

x = 3.56

Therefore, the weight range within which the middle 95% of all miniature Tootsie Rolls will fall is approximately between 3.04 grams and 3.56 grams.

0, 1, 1, 1, 3, 4, 5, 7

Next, find the median (Q2), which is the middle value of the data:

Median (Q2) = (3 + 4) / 2 = 3.5

Since there are 8 data points, we can calculate the position of Q1 and Q3 as follows:

Q1 position = (1/4) * (8 + 1) = 2.25

Q3 position = (3/4) * (8 + 1) = 6.75

Q1 is between the 2nd and 3rd data points: Q1 ≈ (1 + 1) / 2 = 1

Q3 is between the 6th and 7th data points: Q3 ≈ (4 + 5) / 2 = 4.5

(1). The unit rate of per hour is 8 hours.

(2). He bikes 72 miles in 9 hours.

What do you mean by unit rate?

An item's unit rate is its price for one of it. This is expressed as a ratio with a one as the denominator. For instance, if you covered 70 yards in 10 seconds, you covered 7 yards on average every second. Seven yards in one second and 70 yards in ten seconds are both ratios, but only one of them is a unit rate.

According to data in the given question,

We have :

Distance travelled in 3.5 hours = 28 miles

Now, firstly we need to find unit rate per hour,

Distance travelled in 1 hours = 28/3.5 miles

                                               = 8 miles

So, the unit rate of per hour is 8 hours.

Then, we will find the how far can he bike in 9 hours,

Distance travelled in 9 hours = 9*8 miles

                                                = 72 miles

Therefore, he bikes 72 miles in 9 hours.
