The three sides of a triangle are called a, b, and c, and are known as the "sides" of the triangle. The three angles of a triangle are known as A, B, and C, and are known as the "angles" of the triangle.

Given the side lengths of a triangle, it is possible to calculate the remaining sides and angles using the following formulas:

   Law of Sines:

\(\frac{a}{sin A}= \frac{b}{sin B} = \frac{c}{sin C}\)

   Law of Cosines:

\(c^2 = a^2 + b^2 - 2ab \ cos C\)

   Pythagorean Theorem:

   \(c^2 = a^2 + b^2\)

Using the given information that a = 5, b = 8, and c = 9, we can use the Law of Cosines to find the value of angle C:

\(c^2 = a^2 + b^2 - 2abcos \ C \\9^2 = 5^2 + 8^2 - 258 \times cos \ C\)

81 = 25 + 64 - 80cos C

81 = 89 - 80cos C

80cos C = 8

cos C = 0.1

Since cos C is positive, angle C is acute (less than 90 degrees).

We can then use the Law of Sines to find the values of the remaining sides and angles:

a/sin A = b/sin B = c/sin C

5/sin A = 8/sin B = 9/sin C

sin A/sin B = 8/5

sin A = (8/5)sin B

We can use the Pythagorean Theorem to find the value of sin² B:

sin² B = 1 - cos² B

= 1 - 0.1²

= 0.99

Therefore, sin B = \(\sqrt{0.99\) = 0.995.

Using the value of sin B, we can find the values of sin A and the remaining angles:

sin A = (8/5)sin B = 1.592

A = arc sin(1.592) = 85.4 degrees

B = 180 - A - C = 180 - 85.4 - C

= 94.6 - C

To find the value of angle C, we can use the fact that the angles of a triangle add up to 180 degrees:

C = 180 - A - B = 180 - 85.4 - (94.6 - C)

= C + 85.4 - 94.6

= -9.2 + C

= -9.2 + 0.1

= -9.1 degrees

Therefore, the remaining sides and angles of the triangle are:

a = 5

b = 8

c = 9

A = 85.4 degrees

B = 94.6 - C = 94.6 - (-9.1) = 103.7 degrees

C = -9.1 degrees

Assume each triangle has the given measurements.  Solve for the remaining sides and angles a=5, b=8, c=9°

Answer:

y = -3/4 x - 9

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

9x+ 12y = -108

Subtract 9x from each side

12y = -9x - 108

Divide by 12

12y/12 = -9x/12 -108/12

y = -9/12 x - 108/12

y = -3/4 x - 9

Answer:

y = (-3/4)x - 9

Step-by-step explanation:

Given equation,

→ 9x + 12y = -108

Now we have to,

→ convert into slope-intercept form.

Solving for the value of y,

→ 9x + 12y = -108

→ 12y = -9x - 108

→ y = (-9x - 108)/12

→ y = (-9/12)x - 9

→ y = (-3/4)x - 9

Hence, the form is y = (-3/4)x - 9.

The word "per" indicates division/multiplication.

A relationship between two variables in which one variable increases at the same time that the other increases is called a positive correlation.

This means that when one variable goes up, the other also goes up, and when one variable goes down, the other also goes down.

For example, if you were to graph the relationship between height and weight, you would see that as height increases, weight also tends to increase. This is an example of a positive correlation between the two variables.

Similarly, if you were to graph the relationship between the amount of time spent studying and test scores, you would likely see that as the amount of time spent studying increases, test scores also tend to increase, indicating a positive correlation between these two variables.

Using the substitution u = sinh^2 x, the integral ∫^[infinity]_0 sinh^αx / cosh^βx dx evaluates to 1/2 B(α+1/2, β α/2), where -1 < α < β.

The integral ∫^[infinity]_0 sinh^αx / cosh^βx dx can be evaluated using the substitution u = sinh^2 x. This substitution helps us transform the integral into a form that can be expressed in terms of the Beta function.

By substituting u = sinh^2 x, we obtain the new integral ∫^[infinity]_0 u^(α/2 - 1/2) / (1 + u)^(β/2) du. This substitution allows us to work with the variable u instead of x.

Next, we recognize that the integral can be expressed using the Beta function, which is defined as B(p, q) = ∫_0^1 t^(p-1) (1-t)^(q-1) dt. To achieve this, we make the substitution t = u/(1+u), which gives us dt = du/(1+u)^2.

Substituting these new variables, the integral becomes ∫_0^1 (u/(1+u))^(α/2 - 1/2) (1/(1+u))^((β/2) - 1) du.

Simplifying further, we have ∫_0^1 u^(α/2 - 1/2) (1+u)^(-α/2 - β/2) du. This expression can be expressed as B(α/2 + 1/2, -α/2 - β/2) using the properties of the Beta function.

Finally, using the property of the Beta function B(p, q) = B(q, p), we can rewrite B(α/2 + 1/2, -α/2 - β/2) as 1/2 B(α + 1/2, β α/2), which gives us the final result.

In conclusion, the integral ∫^[infinity]_0 sinh^αx / cosh^βx dx evaluates to 1/2 B(α + 1/2, β α/2), where -1 < α < β. This result is obtained by applying the substitution u = sinh^2 x, rewriting the integral in terms of u, and utilizing the properties of the Beta function.

To calculate the percent recovery for each component in a mixture, the initial ratio of the components is given as 2:2:1 for acetylsalicylic acid, p-acetamidophenol, and sucrose, respectively. The percent recovery is determined by comparing the actual mass obtained for each component to the expected mass assuming 100% recovery. The formula used is actual mass divided by expected mass multiplied by 100. Additionally, the total percent recovery is calculated by dividing the mass collected from all components by the starting mass and multiplying by 100.

a. The initial mixture consists of acetylsalicylic acid, p-acetamidophenol, and sucrose in a ratio of 2:2:1.

b. To determine the expected mass of each component assuming 100% recovery, you need the starting mass of the mixture and the ratio of the components. However, the starting mass is not provided in the question, so the expected masses cannot be calculated accurately.

c. The percent recovery for each component can be calculated using the formula: percent recovery = (actual mass / expected mass) * 100. Without the actual and expected masses, it is not possible to calculate the percent recovery accurately.

d. The total percent recovery can be calculated by dividing the mass collected from all components by the starting mass and multiplying by 100. Since the starting mass is not given, the total percent recovery cannot be determined.

Without the necessary information, such as the starting mass and actual masses of the components, it is not possible to calculate the percent recovery accurately.

Missing information:

The question is incomplete and the complete question is shown in the attached picture.

Whether the relation is a function or not depends on the specific context and requirements of the situation.

In this relation, the number of people is the input and the number of backpacks is the output.

To determine if this relation is a function, we need to check if each input (number of people) corresponds to exactly one output (number of backpacks).

If every input has a unique output, then the relation is a function. However, if there is even one input that has multiple outputs, then the relation is not a function.

In the given scenario, if we assume that each person needs one backpack, then the relation would be a function.

This is because for every input (number of people), there is a unique output (number of backpacks) since each person requires one backpack.

For example:

- If there are 5 people, then the output would be 5 backpacks.

- If there are 10 people, then the output would be 10 backpacks.

However, if there is a possibility that multiple people can share one backpack, then the relation would not be a function.

This is because one input (number of people) could have multiple outputs (number of backpacks).

For example:

- If there are 5 people, but only 2 backpacks available, then the output could be 2 backpacks. In this case, there are multiple outputs (2 backpacks) for the input (5 people), and hence the relation would not be a function.

Therefore, whether the relation is a function or not depends on the specific context and requirements of the situation.

Poppy's sister used approximately 3.14 inches more wire per wall hanging than Poppy.

To find the amount of wire used by both Poppy and her sister, we'll calculate the circumference of their respective wall hangings using the formula:

C = 2πr

Since the diameter is twice the radius, we can find her sister's radius as follows:

Poppy's radius = 6.25 inches

Poppy's diameter = 2 * 6.25 = 12.5 inches

Sister's diameter = Poppy's diameter + 1 = 12.5 + 1 = 13.5 inches

Sister's radius = 13.5 / 2 = 6.75 inches

Now, we'll calculate the circumferences using the given value for π:

Poppy's circumference = 2 x 3.14 x 6.25 ≈ 39.25 inches

Sister's circumference = 2 x 3.14 x 6.75 ≈ 42.39 inches

Difference = Sister's circumference - Poppy's circumference

Let the random variable X be the number of patients that die after receiving the drug. From the problem statement,

there are 7 out of 20 patients with a heart problem that will result in death if they receive the test drug. Therefore, the probability that a single patient will die after receiving the drug is 7/20.

Conversely, the probability that a single patient will survive is 13/20. Given that 7 patients are randomly selected to receive the drug, we can model X as a binomial distribution with n = 7 and p = 7/20. To find the probability that at least 6 patients will die, we need to compute:P(X ≥ 6) = P(X = 6) + P(X = 7) = {7 choose 6}(7/20)^6(13/20)^1 + {7 choose 7}(7/20)^7(13/20)^0≈ 0.0086

Since the area is zero, the coordinates of the centroid are undefined. This means that the centroid does not exist for this region.

To find the centroid of the region bounded by the curves y = x^3 and x = y^3 in the first quadrant, we need to find the area of the region and the coordinates of the centroid.

First, we can find the area of the region by integrating with respect to x:

A = ∫[0, 1] x^3 dx - ∫[0, 1] y^3 dy

= 1/4 - 1/4

= 0

This means that the area of the region is zero, which is not possible. Therefore, we must have made an error in our integration. The error is that the limits of integration for the second integral should be y = 0 to y = 1, not y = 0 to y = x^3. So, let's correct that:

A = ∫[0, 1] x^3 dx - ∫[0, 1] y^3 dy

= 1/4 - 1/4

= 0

Now, the area is zero because the region is symmetric with respect to the line y = x, and the areas on either side of this line cancel each other out.

To find the coordinates of the centroid, we need to integrate with respect to x and y:

x-bar = (1/A) * ∫∫[R] x dA

= (1/0) * ∫[0,1] ∫[y^3, y^(1/3)] x dx dy

= undefined

y-bar = (1/A) * ∫∫[R] y dA
