Step-by-step explanation:

So the Taylor series for the function informed will be:

7x, 7x², 21/6 x³, 7/6 x⁴

The function is:

f(x) = 7eˣx

WE need to use the definition of a Taylor series to find the first four non zero terms of the series for f(x) centered at the given value of a.

f(x) = ∑ (fⁿ(a) (x - a)ⁿ)/n!

The first four terms will be:

f(x) = f(0) + f(1) + f(2) + f(3)

f(x) = (f(a) (0- a)ⁿ)/n! + (f'(a) (1 - a)ⁿ)/1! + (f''(a) (2 - a)²)/2! + (f'''(a) (3 - a)³)/3!

Therefore, the four first terms are 7x, 7x², 21/6 x³, 7/6 x⁴

The probability of picking each kind of card is 1/4 or 0.25.

There are four kinds of cards in a standard deck of 52 cards: hearts, diamonds, clubs, and spades. Each kind has 13 cards (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King).

To find the probability of picking a card of each kind, we can use the following formula:

Probability = Number of favorable outcomes / Total number of outcomes

Probability of picking a heart:

There are 13 hearts in the deck, so the number of favorable outcomes is 13. The total number of outcomes is 52, since there are 52 cards in the deck. Therefore, the probability of picking a heart is:

Probability of picking a heart = 13/52

Probability of picking a heart = 1/4

Probability of picking a diamond:

There are 13 diamonds in the deck, so the number of favorable outcomes is 13. The total number of outcomes is still 52, since we haven't replaced the card that we picked earlier. Therefore, the probability of picking a diamond is:

Probability of picking a diamond = 13/52

Probability of picking a diamond = 1/4

Probability of picking a club:

There are 13 clubs in the deck, so the number of favorable outcomes is 13. The total number of outcomes is still 52. Therefore, the probability of picking a club is:

Probability of picking a club = 13/52

Probability of picking a club = 1/4

Probability of picking a spade:

There are 13 spades in the deck, so the number of favorable outcomes is 13. The total number of outcomes is still 52. Therefore, the probability of picking a spade is:

Probability of picking a spade = 13/52

Probability of picking a spade = 1/4

Step-by-step explanation:

The axes labels give you a clue as to the variables: time, volume.

__

The graph is a plot of volume versus time. That is, each point is the volume at a particular time.

The solution to the problem using laws of exponents is: \(\frac{3^{\frac{5}{12} } }{4^{\frac{1}{6} } }\)

Some of the laws of exponents are as follows:

- When multiplying by like bases, keep the same bases and add exponents.

- When you raise the base to the power of 1 to another power, keep the base and multiply by the exponent.

- If dividing by equal bases, keep the same base and subtract the denominator exponent from the numerator exponent.  

We are given the expression as:

\((\frac{3^{\frac{1}{2}} }{4^{\frac{1}{5}} }) ^{\frac{5}{6}}\)

Applying the laws of exponents gives us:

Answer:

x- intercept = - 3

Step-by-step explanation:

to find the x- intercept , where the line crosses the x- axis, let y = 0 in the equation and solve for x

2x - 0 + 6 = 0

2x + 6 = 0 ( subtract 6 from both sides )

2x = - 6 ( divide both sides by 2 )

x = - 3 ← x- intercept

The partial sum of the given sequence, 1 + 10 + 19 + ... + 199, can be found by identifying the pattern and using the formula for the sum of an arithmetic series.  Hence, the partial sum of the sequence 1 + 10 + 19 + ... + 199 equals 4497.

To find the partial sum of the given sequence, we can observe the pattern in the terms. Each term is obtained by adding 9 to the previous term. This indicates that the common difference between consecutive terms is 9.

The formula for the sum of an arithmetic series is Sₙ = (n/2)(a + l), where Sₙ is the sum of the first n terms, a is the first term, and l is the last term.

In this case, the first term a is 1, and we need to find the value of l. Since each term is obtained by adding 9 to the previous term, we can determine l by solving the equation 1 + (n-1) * 9 = 199.

By solving this equation, we find that n = 23, and the last term l = 199.

Substituting the values into the formula for the partial sum, we have:

S₂₃ = (23/2)(1 + 199),

= 23 * 200,

= 4600.

However, this sum includes the terms beyond 199. Since we are interested in the partial sum up to 199, we need to subtract the excess terms.

The excess terms can be calculated by finding the sum of the terms beyond 199, which is (23/2)(9) = 103.5.

Therefore, the partial sum of the given sequence is 4600 - 103.5 = 4496.5, or approximately 4497 when rounded.

Hence, the partial sum of the sequence 1 + 10 + 19 + ... + 199 equals 4497.

Step-by-step explanation:

The Area of a trapezoid is:

1/2 (a + b) h

Where ;

a = Length of base 1

b = length of base 2

h = height of trapezium

From the diagram attached :

a = Length of BC =(-1 to 3) =4units

b = length of AD =(-3 to 5) = 8 units

h = (-2 to 2) = 4 units

Plugging the values :

Area = 1/2 ((4 + 8)2)

Answer:

The 8 square meters represent the product of the height by the width of the wall and therefore, its area.

Step-by-step explanation:

Ginnie is going to paint a wall and measures the height and the width, the walls are usually in the form of a rectangle or square. To find the area of both we need to multiply the height by the width (in the case of the square both are the same) and this will give us the total amount of paint that we need to paint the wall.

In this example, Ginnie finds that she needs enough paint to cover 8 square meters, therefore, these 8 square meters represent the product of the height by the width (that we don't know but it doesn't matter) of the wall and therefore, its area.

The change of the distance travelled by the ball when the angle of launch

changes can be found by linear approximation.

Reasons:

The distance of the player from the basket = 18.6 ft.

Height from which the jump shot is launched = 10 ft.

Angle of the jump shot = 36°

The initial velocity = 25 ft./s

According to Newton's Law of motion, the distance an object travels when

released at an angle θ, with an initial velocity, v, is given by the following

horizontal range formula equation;

\(s = \dfrac{1}{32} \cdot v^2 \cdot sin(2 \cdot \theta)\)

\(\dfrac{ds}{d\theta} =\dfrac{d}{d\theta } \left( \dfrac{1}{32} \cdot v^2 \cdot sin(2 \cdot \theta) \right)= \dfrac{v^2 \cdot cos(2 \cdot \theta)}{16}\)

By linear approximation, we have;

\(\Delta s = \dfrac{ds}{d\theta} \times \Delta \theta\)

Which gives;

\(\Delta s =\dfrac{25^2 \cdot cos(2 \times 36^{\circ})}{16}\times \Delta \theta \approx 12.07 \times \Delta \theta\)

360° = 2·π radians

\(12.07 ^{\circ} = \dfrac{2 \cdot \pi}{360} \times 12.07 \approx 0.211 \ radians\)

Δs ≈ 0.211·Δθ

Therefore;

The change in the distance, Δs, when the angle changes by Δθ is 0.211·Δθ.

The association between lung function (FEV) and age can be observed through the analysis of the provided output from R.

The output from R likely includes statistical measures such as correlation coefficients or regression analysis results to determine the relationship between FEV and age. These calculations can help quantify the association between the two variables. For example, a correlation coefficient can indicate the strength and direction of the relationship, where a positive value suggests a positive association between FEV and age.

Based on the provided output from R, it can be concluded that there is an association between lung function (FEV) and age. However, without the actual output or specific statistical measures, it is challenging to provide further details or draw more precise conclusions. It is important to consider that the association between FEV and age may not necessarily imply causation, as other factors such as lifestyle, health conditions, and genetics can also impact lung function. Further analysis and additional data would be necessary to fully understand the nature and significance of this association.

Overall, it is reasonable to conjecture that lung function (FEV) changes with age, but a comprehensive analysis of the provided output and additional research would be required to establish the precise relationship between the two variables.

Therefore, the probability that the bus will arrive tomorrow between 8:00 AM and 8:02 AM is 20%.

To find the probability that the bus will arrive tomorrow between 8:00 AM and 8:02 AM, we need to consider the time range during which the bus could arrive.

The bus always arrives between 8:00 AM and 8:10 AM, which means there are 10 minutes in total for the bus to arrive.

The desired time range is between 8:00 AM and 8:02 AM, which is a 2-minute interval.

To find the probability, we divide the desired time range (2 minutes) by the total time range (10 minutes):

Probability = Desired time range / Total time range

= 2 minutes / 10 minutes

Step-by-step explanation:

The number of cars were going between 40 and 48 miles per hour is 25. Therefore, option C is the correct answer.

A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile. A vertical line goes through the box at the median.

From the given box plot, we have

Minimum value = 37

Maximum value = 69

First quartile = 40

Third quartile = 55

Mean = 47

The distance between Q1 and the median is 25%.

The number of cars between 40 and 48 miles per hour is therefore 25% of the total.

There are 846720 different values possible for the sum of xyx and yxy.

Let's denote the three digits of xyx as a, b, and c, such that xyx = 100a + 10b + c, and the three digits of yxy as d, e, and f, such that yxy = 100d + 10e + f. Note that x and y are distinct non-zero digits, so a, b, c, d, e, and f are all distinct non-zero digits.

The sum of xyx and yxy is (100a + 10b + c) + (100d + 10e + f), which simplifies to 100(a+d) + 20(b+e) + (c+f).

We want to find how many different values are possible for the sum. Since a, b, c, d, e, and f are all distinct non-zero digits, we can consider each of them separately.

For a given value of a, there are 9 choices for d (since d cannot be equal to a), and once we have chosen d, there are 8 choices for e (since e cannot be equal to either a or d). Similarly, there are 7 choices for f (since f cannot be equal to a, d, or e).

So, for a fixed value of a, the number of possible values of the sum is the number of possible values of (100(a+d) + 20(b+e) + (c+f)), which is simply the number of possible values of (20(b+e) + (c+f)), since 100(a+d) is fixed.

There are 8 choices for b (since b cannot be equal to a), and once we have chosen b, there are 7 choices for c (since c cannot be equal to either a or b). Similarly, there are 6 choices for e (since e cannot be equal to either a, d, or b), and 5 choices for f (since f cannot be equal to either a, d, e, or c).

Therefore, the total number of possible values of the sum is:

9 × 8 × 7 × 8 × 7 × 6 × 5 = 846720

Therefore, there are 846720 different values possible for the sum of xyx and yxy.
