The skid marks be to the nearest foot is 913 ft.

The length of the skid marks can be calculated using the formula d = μV2/2gdf, where μ is the coefficient of static friction, V is the velocity, g is the acceleration due to gravity, and df is the drag factor. In this case, the coefficient of static friction can be assumed to be 0.9, the velocity is 35 mi/h, the acceleration due to gravity is 32.2 ft/s2, and the drag factor is 0.97. Plugging these values into the formula, we get [tex]d = 0.9(35 mi/h x 5280 ft/mi/h)2/2(32.2 ft/s2)(0.97) = 912.5 ft[/tex]. To the nearest foot, this is 913 ft.

Answer:

B

Step-by-step explanation:

Use the distance formula.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

In which:

Two points on the function are given as follows:

(10, 110) and (20, 220).

The slope is given by the change in the output divided by the change in the input, hence:

m = (220 - 110)/10

m = 11.

Hence:

y = 11x + b.

When x = 10, y = 110, hence the intercept b is given as follows:

110 = 11(10) + b

b = 0.

Hence the function giving the cost for x people is of;

y = 11x.

The cost for 60 people would be of:

y = 11(60)

y = $660.

Answer: -1/12

Step-by-step explanation:

Answer:

-1/12

Step-by-step explanation:

9/4 - 7/3

To start, we need to make the denominators the same number.  In order to do that, we need to identify the factor they have in common.

4, 8, 12

3, 6, 9, 12

Twelve is the common factor, so we will use this.  Remember, whatever you do to the bottom, you must do to the top, and vice versa.

4 * 3 = 12

/12

3 * 9 (numerator) = 27

27/12

     Now, we must figure out 7/3.

3 * 4 = 12

Answer: 37.5

Step-by-step explanation:

62.5 * (3/5) = 37.5

The values of the terms, a₁, a₂, and a₁₀ of the sequence are;

(a) a₁ = 1, a₂ = 1/2, a₁₀ = 1/10

(b)  [tex]\lim\limits_{n\to {\infty}}[/tex] aₙ = 0

A sequence is an ordered collection of objects such as numbers in which repetition of the object is possible, and the objects (or numbers) are referred to as the terms of the sequence.  

The sequence, [tex]\{a_n\}^\infty_{n = 1}[/tex] with values, aₙ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{n + 1}} }[/tex]

(a) a₁ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{1 + 1}} } = \int\limits^{\infty}_1 {\frac{dx}{x^2} } = -[\frac{1}{x} ]^{\infty}_1[/tex]

[tex]-[\frac{1}{x} ]^{\infty}_1 = -\frac{1}{\infty} - (-\frac{1}{1} ) = 0 + 1 = 1[/tex]

Therefore; a₁ = 1

a₂ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{2 + 1}} } = \int\limits^{\infty}_1 {\frac{dx}{x^3} } = -[\frac{1}{2\cdot x^2} ]^{\infty}_1[/tex]

[tex]-[\frac{1}{2\cdot x} ]^{\infty}_1 = -\frac{1}{\infty} - (-\frac{1}{2 \times 1} ) = 0 + \frac{1}{2} = \frac{1}{2}[/tex]

Therefore; a₂ = 1/2

a₁₀ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{10 + 1}} } = \int\limits^{\infty}_1 {\frac{dx}{x^{11}} } = [-\frac{1}{10\cdot x^{10}} ]^{\infty}_1[/tex]

[tex][-\frac{1}{10\cdot x^{10}} ]^{\infty}_1 = -\frac{1}{\infty} - (-\frac{1}{10\times 1} ) = 0 + \frac{1}{10} = \frac{1}{10}[/tex]

Therefore; a₁₀ = 1/10

b) The limit, [tex]\lim \limits_{n\to \infty} a_n[/tex] can be evaluated as follows;

aₙ = [tex]\int\limits^{\infty}_1 {\frac{dx}{x^{n+1} } } \, dx[/tex]

[tex]\int\limits^{\infty}_1 {\frac{dx}{x^{n+1} } } \, dx = [-\frac{1}{n\cdot x^n} ]^{\infty}_1 = -\frac{1}{n\times \infty } - (-\frac{1}{n\times 1^n} )= \frac{1}{n}[/tex]

aₙ = 1/n

Therefore;

[tex]\lim \limits_{n\to \infty} a_n = \frac{1}{\infty}[/tex] = 0

The predicted cost of postage for 2013 is 45 cents.

We need to use the exponential regression model to predict the cost of postage for the year 2013, given that it was 63 years since 1950.

Let's assume that the cost of postage can be modeled using the exponential function:

C(t) = a * e^(kt)

where:

We can use the two data points we have to solve for a and k:

Using the above data points, we can solve for k as follows:

0.03 = a * e^(0 * k)

0.46 = a * e^(63k)

Dividing the second equation by the first equation, we get:

15.333 = e^(63k)

Taking the natural logarithm of both sides, we get:

k = ln(15.333)/63

Evaluate

k = 0.043

Now that we have k, we can use it to predict the cost of postage in 2013:

C(63) = a * e^(63k)

C(63) = 0.03 * e^(63 * 0.043)

C(63) = 0.45

Hence, according to the exponential regression model, the cost is 45 cents.

Step-by-step explanation:

If there is a hole in the graph at x = -6, that means that there was initially an expression in both the numerator and the denominator that was the same, which is the hole very loosely defined. If the hole is at x = -6, then the factor for that solution is (x + 6). One of those has to be in both the numerator and denominator in order for them to cancel out. This is called a removeable discontinuity. Because the x-intercept is at x = 3, the factor for that zero is (x -3). That has to go in the numerator also. Our equation then for the rational function graphed is

[tex]y=\frac{(x+6)(x-3)}{(x+6)}[/tex] which FOILs to

There are several ways to find the zeros of the function x^4–18x^2+12x+80. You can graph the equation and see where it crosses the x axis.The graph crosses at x=-4,-2. This means that -4, and -2 are roots, and (x+4) and (x+2) are factors. I like synthetic division the best when it comes to factoring. I teach synthetic division when we get to problems like this, so I will assume that you are familiar with it.First take the coefficients of the equation x^4–18x^2+12x+80 I have to usex^4 +0 x^3 –18x^2+12x+80 : 1 0 -18 12 80. I will use -4 first.If you are not supposed to graph it, then you can use synthetic division. It can take longer because you have to “guess “ at the factors using an educated guess from the factors of =/- p/q . Where p is the last coefficient and q is the first coefficient.In this case we need to find the factors of 80/1 . These are 1,2,4,5,8,10,16,20,40,80. So possible roots are +/- (1,2,4,5,8,10,16,20,40,80). Students usually start with the smaller numbers and work up, So I would try 1 first then 2 etc.Now another way to find the factors is to use 10 as x and to see what the answer is, then try to factor the results. f(x)=x^4–18x^2+12x+80 f(10)=10,000–1800+120+80=8400I can factor 8400 into 100 *6 *14, or (10+0) *(10+0)*(10–4)*(10+4). 0 is not a factor from above, but +/- 4 is. So I could try those two numbers. Looking at the possible roots using 10 as my x, I would need to look at 9,11, 8,12, 0,20 -4,26, etc

La respuesta de su problemamatemático es X= 6.63

Answer: To find the volume of the combined shape, we need to find the volume of the cone and the volume of the hemisphere and add them together.

For the cone:

Volume = 1/3 * pi * r^2 * h

Where r is the radius and h is the height. In this case, r = 8 cm and h = 12 cm. So,

Volume = 1/3 * pi * 8^2 * 12 = (1/3) * pi * 64 * 12 = 256 * pi cm^3

For the hemisphere:

Volume = (2/3) * pi * r^3

Where r is the radius. In this case, r = 8 cm. So,

Volume = (2/3) * pi * 8^3 = (2/3) * pi * 512 cm^3

Adding the volumes of the cone and the hemisphere, we have:

Volume = 256 * pi + (2/3) * pi * 512 cm^3 = 256 * pi + 341.3333 * pi cm^3

To the nearest integer, the volume of the combined shape is:

Volume = round(256 * pi + 341.3333 * pi) = round(597.3333 * pi) = 1876 cm^3

In "The Jungle" by Upton Sinclair, Jurgis is a character who starts out with a positive and optimistic outlook on life. He is full of hope and ambition when he arrives in America with his family, eager to make a better life for himself. However, after he is injured on the job and becomes unable to work, his attitude changes dramatically. He becomes disillusioned and bitter, losing his hope and faith in the American Dream.

In my opinion, Jurgis's response to his injury reflects the harsh realities of life for immigrants and the working class in America during that time. The injury not only physically incapacitates him, but it also robs him of his ability to provide for his family and live out his dreams. The experience shows the extent to which the system is stacked against those in Jurgis's position and serves as a powerful commentary on the injustices and inequalities of the time.
