To compare the two running times, we need to express them in the same units. We can convert Sylvester's time to seconds by multiplying by 60:

Sylvester: 4 minutes x 60 seconds/minute = 240 seconds

Lenworth: 4 minutes 12 seconds = 4 x 60 + 12 = 252 seconds

Now we can find the ratio of Lenworth's time to Sylvester's time:

Lenworth/Sylvester = 252/240 = 21/20

So the ratio of Lenworth's time to Sylvester's time is 21:20.

Answer:

The answer is d) 2/c.

Explanation :

If one of the zeroes of cubic polynomial x^3+ax^2+bx+c is 2, then the product of the other two zeroes can be found by dividing the polynomial by (x-2), which gives:

x^3+ax^2+bx+c = (x-2)(x^2+(a+2)x+(c-2a))

We can solve the quadratic equation x^2+(a+2)x+(c-2a) to find the other two zeroes. By Vieta's formulas, the product of the roots of a quadratic equation ax^2+bx+c=0 is c/a. Therefore, the product of the other two zeroes is:

pq = (c-2a)/1 * 1/(a+2) = (c-2a)/(a+2)

Substituting the value of c/2a from the cubic polynomial gives:

pq = (c-2a)/(a+2) = (2c-4a)/(2a+4) = -2(c/2a) + 2

Therefore, the answer is d) 2/c.

Step-by-step explanation:

there are 2 formulas to calculate the length of a chord, depending on what pieces of information we have.

here now we have the length of the chord, which we need to find the radius, which we need to find the angle at the center.

chord length = 2×sqrt(r² - d²)

chord length = 2×r×sin(c/2)

r is the radius, d is the distance of the chord from the center of the circle, c is the angle of the chord at the center of the circle.

20 =2×sqrt(r² - 12²) = 2×sqrt(r² - 144)

10 = sqrt(r² - 144)

100 = r² - 144

244 = r²

r = 15.62049935... cm

20 = 2×r×sin(c/2) = 2×15.62049935...×sin(c/2)

10 = 15.62049935...×sin(c/2)

sin(c/2) = 10/15.62049935... = 0.6401844...

c/2 = 39.80557109...°

c = 79.61114218...° ≈ 79.6°

(a) the angle subtended by the chord at the center of the circle is about 79.6°.

(b)

the arc length of a segment is 2pi×r × c/360

in our case

2×3.142×15.62049935...×79.61114218.../360 =

the whole perimeter of the segment is then arc length + chord length =

the perimeter of the minor segment cut off by the chord is about 41.7 cm.

The probability of winning the minimum prize is approximately 0.00014

To calculate the probability of winning this minimum prize, we need to first find out the total number of possible combinations of numbers that can be drawn.

There are 56 white balls, and 5 balls are drawn from them, so the total number of possible combinations of white balls is

56 choose 5 = 56! / (5! (56-5)!) = 3,819,816

There are 46 gold balls, and only 1 is drawn from them. Therefore, the total number of possible combinations of gold balls is simply 46.

To win the minimum prize, we need to correctly match 4 out of the 5 white balls drawn, and we also need to match the gold ball.

The number of ways to choose 4 white balls out of 5 is

5 choose 4 = 5! / (4! (5-4)!) = 5

So, the total number of ways to win the minimum prize is the product of the number of ways to choose 4 white balls and the number of ways to choose 1 gold ball

Total number of ways to win the minimum prize = 5 × 46 = 230

Therefore, the probability of winning the minimum prize is

Probability = number of ways to win the minimum prize / total number of possible combinations

Probability = 230 / (3,819,816 × 46) = 0.00014

Answer:

a)  $16,122

b) $4,246

c) $112,357

Step-by-step explanation:

What is depreciation

We should calculate the depreciation using the declining balance method
This uses the technique of computing the depreciation on the previous year's depreciated value

As an example
If the original cost is $100 and depreciation rate is 10%( 0.10 in decimal)

Depreciation Year 1 = 100 x 0.10 = $10

Depreciated value at end of year 1 = 100 - 10 = $90

For the second year, the depreciation amount is computed on $90
= 90 x 0.10 = $ 9

Depreciated amount at end of year 2 = 90 - 9 = $81

The depreciated value of an asset valued at $A at time of purchase at a depreciation rate of r (in decimal) for n years is given by the formula
A' = A(1 - r)ⁿ

We are given
A = $34,145
r = 8/100 = 0.08 therefore 1 - r = 1 - 0.08 = 0.92

a) Depreciated value after 9 years:
A' = 34145(0.92)⁹
    = 16121.95

Rounded to the nearest dollar that would be $16,122 ANSWER

b) Depreciated Value after 25 years

A' = 34145(0.92)²⁵

    = $4,246  rounded to the nearest dollar

c) Car's value after 50 years

At the end of 25 years, the Mustang has become a classic with a value of $4, 246

Then it starts to appreciate at the rate of 14% (0.14 in decimal)

The appreciated value each year after 25 years is given by
A'' = A'( 1 + r)ⁿ

where r is the rate of appreciation and n is the number of years

We are given r = 14% = 0.14

1 + r = 1.14

n = 25

A' = 4,246 the value after 25 years from purchase

Car value after 50 years = car value after 25 years appreciated for the next 25 years

= 4246(1.14)²⁵

= $112,357 rounded to the nearest $

So you can really make a killing after 25 years. As an interesting side note, the value of the car will reach the original value 16 years after 25 years or a total of 41 years after purchase

1. Identify the curve and the point: The curve is y = sec(x), and the point is (π/6, 2√3/3).

2. Calculate the derivative of the curve: The derivative of y = sec(x) is y' = sec(x)tan(x).

3. Evaluate the derivative at the given point: At x = π/6, we have y' = sec(π/6)tan(π/6). Since sec(π/6) = 2 and tan(π/6) = √3/3, we get y' = 2(√3/3) = 2√3/3.(4). Use the point-slope form of the line equation: y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope (derivative).

5. Plug in the values: y - (2√3/3) = (2√3/3)(x - π/6). This is the equation of the tangent line to the curve y = sec(x) at the point (π/6, 2√3/3).

With a significance level of 0.05 for a one-tailed test, the critical value is 1.761. Since -1.86 is less than -1.761, we reject the null hypothesis.

To test for significant increases in average domestic business charges over a one-year period, you can use a paired-sample t-test.

This is good because the two sets of observations (current year and previous year) are paired on the same flight.

The null hypothesis (H0) states that the average domestic fares for business travel are not significantly different from the previous year.

The alternative hypothesis (Ha) indicates that average domestic fares for business travel will increase significantly this year compared to the previous year.

This can be written as:

H0:

µd = 0

teeth:

µd > 0

where μd is the population mean of the differences in domestic fares between the current year and the previous year.

To do the test, to begin with, calculate the contrast between the residential passages for the current year and the past year.

At that point calculate the mean and standard deviation of these contrasts.

 d = (558-219) + (417-312) + ... + (348-369) / 15

= -15.2

s = sqrt([(558-219+15.2)^2 + ... + (348-369+15.2)^2] / (15-1))

= 134.8

The t-statistic for the test is

t = (d - 0) / (s / sqrt(n))

= (-15.2 - 0) / (134.8 / square(15))

= -1.86

Using a one-sided test with 14 (n-1) degrees of freedom and a t table with a significance level of 0.05, the critical value is 1.761. -1.86 is less than -1.761, so we reject the null hypothesis.

Answer:Width=5, Length=10

Step-by-step explanation:

You can solve this by using a variable, x, and assigning it to the value that is the width.

Since the perimeter of a rectangle is the width times two plus the length times two, you can use an equation that looks like this:

(image shown)

This will give you the value of X, the width, and you can multiply this value by 2 to get the length.

Answer:

10 cm

Step-by-step explanation:

The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter, l is the length and w is the width1. We know that the perimeter of this rectangle is 30 cm. So we can write:

2(2w + w) = 30

Simplifying this equation gives:

6w = 30

Therefore:

w = 5

So the width of the rectangle is 5 cm and its length is twice as long as its width which means it’s 10 cm.

Answer: BC = 8.94

Step-by-step explanation:

      Since this is a right triangle, we can use the Pythagorean theorem. a and b are the triangle legs and c is the hypotenuse.

a² + b² = c²

19² + b² = 21²

361 + b² = 441

b² = 80

b = [tex]\sqrt{80}[/tex]

b ≈ 8.94

BC = 8.94

Answer:

Step-by-step explanation:

The perimeter of a triangle is the sum of the lengths of its sides. Therefore, to find the perimeter of the triangle with sides a = 24, b = 45, and c = ?, we need to add up the lengths of the known sides:

Perimeter = a + b + c

Plugging in the values, we get:

Perimeter = 24 + 45 + c

Simplifying, we get:

Perimeter = 69 + c

We still need to find the length of the third side, c. However, we can use the fact that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In other words:

a + b > c

24 + 45 > c

69 > c

Therefore, we know that c must be less than 69.

On the other hand, we can also use the fact that the difference between the lengths of any two sides of a triangle must be less than the length of the third side. In other words:

|a - b| < c

|24 - 45| < c

21 < c

Therefore, we know that c must be greater than 21.

Putting these two inequalities together, we have:

21 < c < 69

So the perimeter is:

Perimeter = 69 + c

And we know that:

21 < c < 69

Therefore, we can say that the perimeter is somewhere between:

69 + 21 = 90

and

69 + 69 = 138

Rounding to the nearest tenth, we get:

Perimeter ≈ 90.0 - 138.0

Therefore, the perimeter is somewhere between 90.0 and 138.0, depending on the actual length of the third side, c.
