Applying implicit differentiation, it is found that:

[tex]\frac{d^2y}{dx^2}(4,3) = \frac{7}{27}[/tex]

The curve given is:

[tex]x^2 + y^2 = 25[/tex]

Applying implicit differentiation, we have that the first derivative is:

[tex]2x\frac{dx}{dx} + 2y\frac{dy}{dx} = 0[/tex]

[tex]2y\frac{dy}{dx} = -2x[/tex]

[tex]\frac{dy}{dx} = -\frac{x}{y}[/tex]

Again applying implicit differentiation, the second derivative is:

[tex]\frac{d^2y}{dx^2} = -\frac{y\frac{dx}{dx} - x\frac{dy}{dx}}{y^2}[/tex]

Since [tex]\frac{dy}{dx} = -\frac{x}{y}[/tex]

[tex]\frac{d^2y}{dx^2} = -\frac{y - \frac{x^2}{y}}{y^2}[/tex]

[tex]\frac{d^2y}{dx^2} = \frac{x^2 - y^2}{y^3}[/tex]

At point (4,3), [tex]x = 4, y = 3[/tex], then:

[tex]\frac{d^2y}{dx^2}(4,3) = \frac{4^2 - 3^2}{3^3} = \frac{7}{27}[/tex]

Final answer:

Given that A is a subset of B and the intersection of A and B is the empty set, it is conclusive that A is the empty set, and we cannot infer anything about the elements of set B.

Explanation:

When considering sets, subset relation and intersection are fundamental concepts. If A ⊆ B(A is a subset of B) and A ∩ B = θ (the intersection of A and B is the empty set), we can conclude that every element in A is also in B, but since the intersection is empty, A has no elements. Therefore, A is the empty set, which means that A contains no elements. It is not possible to determine the contents of set B or to compare the cardinalities of A and B, since we only know that A is empty.

Observing our subset and intersection principles, while A is a subset of B, the fact that they have an empty intersection invariably means that A cannot contain any member, thereby being the empty set. The other options given in the question are incorrect based on our set theory principles. Set B can be any set; it might not be empty, and it is not possible to make any conclusions about the number of elements in B relative to A from the information given.

Final answer:

To simplify the expression sec(y) sin(π/2 - y) using basic identities, we can use the identity sec(y) = 1/cos(y) and expand the expression using the identity sin(a - b) = sin(a)cos(b) - cos(a)sin(b). The simplified expression is -tan(y).

Explanation:

To simplify the expression sec(y) sin(π/2 - y) using basic identities, we can start by using the identity sec(y) = 1/cos(y). So the expression becomes (1/cos(y)) sin(π/2 - y). Next, let's use the identity sin(a - b) = sin(a)cos(b) - cos(a)sin(b) to expand the expression. We have (1/cos(y)) (cos(y)cos(π/2) - sin(y)sin(π/2)). Since cos(π/2) = 0 and sin(π/2) = 1, the expression simplifies to (1/cos(y)) (0 - sin(y)(1)), which further simplifies to -sin(y)/cos(y). Therefore, the simplified expression is -tan(y).

The number 4.24 in its decimal form is already a simplified numerical value, it does not require conversion to a simplified radical form, unless it's interpreted as the square root of 4.24.

The student is wanting to know the simplified radical form of 4.24. The student's proposed answer of 106/25 indicates that they are interpreting the number as a fraction. As the number 4.24 is already a decimal, which is a form of a simplified numerical expression, it does not need conversion to a simplified radical form or fraction. A number in radical form typically denotes the square root of a number, for which 4.24 does not have a simple whole number equivalent.

In summary, 4.24 in its decimal expression is already a simplified numerical value. Unless it is interpreted as the square root of 4.24, which represents an entirely different value and is not commonly presented in radical form when it's a decimal.

The number 4.24 can be simplified to 106/25.

No, actually, you're right!  The decimal number 4.24 can be expressed as the simplified fraction 106/25.

Here is how:

1. First, express the number 4.24 as a fraction, understanding that the number after the decimal point stands for hundredths. Thus, we can write it as 424/100.

2. Next, we need to simplify the fraction. To do that, we find the greatest common divisor (GCD) of 424 and 100. The gcd of 424 and 100 is 4.

3. Now we divide both the numerator and the denominator by the gcd. So, 424 divided by 4 is 106, and 100 divided by 4 is 25.

4. Now we write the simplified fraction as 106/25.

However, it seems there's a misunderstanding in the question. The term 'radical form' usually refers to the square root of a number which we can only do in contrast to perfect square numbers (those whose square root is a whole number). However, the decimal number 4.24 doesn't have a perfect square root, so it can't be expressed in 'radical form'. But, as per your query, 106/25 is the simplified fractional form of 4.24.

Answer: the correct answer is D.

Step-by-step explanation:

The possible sets of two sides for the lengths of the other two sides of the triangle are: 5 cm and 8 cm, 6 cm and 7 cm, and 8 cm and 8 cm.

To determine which set of two sides is possible for the lengths of the other two sides of the triangle, we can use the Triangle Inequality Theorem. According to the theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

In this case, if one side of the triangle is 13 cm, then the sum of the other two sides must be greater than 13 cm in order for the triangle to be valid.

Let's check each set of two sides:

Based on the Triangle Inequality Theorem, the sets of two sides that are possible are: 5 cm and 8 cm, 6 cm and 7 cm, and 8 cm and 8 cm.

Final answer:

The third piece of wood must be longer than 9 ft but shorter than 35 ft to make a triangular garden bed with the other two pieces, adhering to the Triangle Inequality Theorem.

Explanation:

To determine the possible length of the third piece of wood to create a triangular garden bed with the other two pieces measuring 22 ft and 13 ft, we need to recall the Triangle Inequality Theorem. This theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. Conversely, the difference between these two sides must be less than the length of the remaining side.

Step 1: Identify the lengths of the two given pieces: 22 ft and 13 ft.

Step 2: To find the minimum length of the third piece, subtract the shorter piece from the longer piece, then add a small value to avoid equality (as the sum must be greater).

Minimum length > 22 ft - 13 ft => 9 ft + a small value

Step 3: To find the maximum length of the third piece, sum the lengths of the two pieces and subtract a small value (as the length must be less than the sum of the other two pieces).

Maximum length < 22 ft + 13 ft => 35 ft - a small value

So, the third piece of wood must be longer than 9 ft but shorter than 35 ft to form a triangle with the other two pieces.

the one above is incorrect the real answer is 10 meters per second and you don't really need an equation for this (it's pretty obvious ) :)

Final answer:

To write 90 as a product of prime factors, divide it by the smallest prime numbers in sequence: 90 = 2 × 3 × 3 × 5, which can also be expressed using exponents as 90 = 2 × 3² × 5.

Explanation:

Writing 90 as a product of prime factors involves breaking down the number into its prime number components. To do this, we start by finding the smallest prime number that divides into 90, which is 2. We then divide 90 by 2 to get 45. Since 45 is not a prime number, we continue the process and find the smallest prime number that divides into 45, which is 3. Dividing 45 by 3 gives us 15. Again, 15 is not prime, so we divide it by its smallest prime divisor, 3, which results in 5. Now, 5 is a prime number, so we have now expressed 90 as a product of prime factors:

90 = 2 × 3 × 3 × 5

Step-by-Step Process:

Divide 90 by the smallest prime number 2, resulting in 45.

Divide 45 by the smallest prime number 3, resulting in 15.

Divide 15 by 3 again, resulting in 5.

Write down the result as a multiplication of these prime factors: 2 × 3 × 3 × 5.

This factorization can also be written with exponents to show repeated factors: 90 = 2 × 3² × 5.

Final answer:

The probability of rolling a number less than or equal to 8 with two dice, given at least one die shows a 6, is 5/36, considering all the valid dice combinations that meet the criteria.

Explanation:

The probability of rolling a number less than or equal to 8 with two dice, given at least one must be a 6, is calculated by considering the possible combinations of dice that adhere to these conditions. First, we determine how many outcomes include at least one 6:

If the first die is a 6, the other die can be 1, 2, or a 3 (since 6+4 is already 10, which is greater than 8).

If the second die is a 6, the first die can again be 1, 2, or 3.

Both dice can be 6, which adds one more outcome.

These are mutually exclusive events, therefore we add their probabilities. There are 5 outs of 36 possible rolls (3+3) when the numbers can sum up to less than or equal to 8 with at least one die showing a 6 (1+6, 2+6, 3+6, 6+1, 6+2, 6+3).

The probability of rolling a number less than or equal to 8, given that at least one die shows a 6, is 5/36.

The probability of rolling a number less than or equal to 8 with two dice, given that at least one die shows a 6, is [tex]\( \frac{10}{11} \).[/tex]

To find the probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6, we can use conditional probability.

Let's consider the outcomes where at least one die shows a 6:

- (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)

- (1, 6), (2, 6), (3, 6), (4, 6), (5, 6)

Out of these 11 outcomes, the ones where the sum of the two dice is less than or equal to 8 are:

- (6, 1), (6, 2), (6, 3), (6, 4), (6, 5)

- (1, 6), (2, 6), (3, 6), (4, 6), (5, 6)

So, there are 10 favorable outcomes out of 11 possible outcomes when at least one die shows a 6.

Therefore, the probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6, is [tex]\( \frac{10}{11} \).[/tex]

The airplane must head approximately 16.7° east of due north to compensate for the westward wind blowing at 30 m/s while attempting to fly due north at 100 m/s.

To determine the heading (angle and direction) that the airplane should take to compensate for the wind and fly due north, we need to consider the velocity of the plane relative to the air and the velocity of the wind. The plane wants to fly due north at 100 m/s, but the wind is blowing from the west at 30 m/s. This problem involves vector addition and can be solved graphically or using trigonometry.

Graphically, we would draw a vector to represent the plane's intended velocity due north (100 m/s) and then a vector to represent the wind's velocity (30 m/s) to the east of the northward vector. The result is a right-angled triangle where the plane's velocity is the hypotenuse, and the wind's velocity is one of the sides. Using trigonometry, we can calculate the required heading of the plane.

To find the angle (θ) between the plane's heading and the due north direction, we can use the tangent function:

Calculator error is often in degrees or radians, so ensure which mode you are using. Assuming we need the angle in degrees, we find that:

Thus, the airplane must head 16.7° east of due north to compensate for the wind and fly due north.
