No triangles can be constructed with the given side lengths.

As, The triangle inequality is a mathematical theorem that states 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, for a triangle with sides a, b, and c, where c is the longest side, the following inequality holds true:

a + b > c

Here, sides of triangle are 4cm, 5 cm and 9 cm.

So, 4 + 5 = 9

Thus, No triangles can be constructed with the given side lengths.

[tex]\textsf{A.}\quad\dfrac{1}{3} \ln \left|\sec(3x+1)+\tan(3x+1)\right|+\text{C}[/tex]

Step-by-step explanation:

[tex]\displaystyle \int \text{f}(x)\:\text{d}x=\text{F}(x)+\text{C} \iff \text{f}(x)=\dfrac{\text{d}}{\text{d}x}(\text{F}(x))[/tex]

If differentiating takes you from one function to another, then integrating the second function will take you back to the first with a constant of integration.

Given integral:

[tex]\displaystyle \int \sec(3x+1)\; \text{d}x[/tex]

To evaluate the given integral, use the method of integration by substitution.

Let u = 3x + 1.

Find du/dx and rewrite it so that dx is on its own:

[tex]\dfrac{\text{d}u}{\text{d}x}=3 \implies \text{d}x=\dfrac{1}{3}\;\text{d}u[/tex]

Rewrite the original integral in terms of u and du and integrate:

[tex]\begin{aligned}\displaystyle \int \sec(3x+1)\; \text{d}x&=\int \dfrac{1}{3} \sec(u)\; \text{d}u\\\\&= \dfrac{1}{3}\int \sec(u)\; \text{d}u\\\\&= \dfrac{1}{3} \ln \left|\sec(u)+\tan(u)\right|+\text{C}\end{aligned}[/tex]

Finally, replace u with the original substitution.

y = x².

To obtain the inverse, first we exchange y and x, hence:

x = y².

Finally, we must isolate the variable y, hence:

[tex]y = \pm \sqrt{x}[/tex]

[tex]y = \sqrt{x}[/tex] -> we take only the positive and the domain is the non-negative numbers.

To solve for the remaining angles and side of the triangles, we can use the Law of Sines and the Law of Cosines.

Triangle 1: (where angle A is acute)

Given:

B = 50°

b = 5

a = 6

Using the Law of Sines:

[tex]sin A / a = sin B / b[/tex]

sin A / 6 = sin 50° / 5

sin A = (6 x sin 50°) / 5

A = arcsin[(6 x sin 50°) / 5]

A ≈ 44.14°

Using the Law of Sines again:

sin C / c = sin B / b

sin C / c = sin 50° / 5

sin C = (c x sin 50°) / 5

Using the Law of Cosines:

c² = a² + b² - 2ab x cos C

c² = 6² + 5² - 2(6)(5) x cos C

c² = 36 + 25 - 60 x cos C

c² = 61 - 60 x cos C

c ≈ √(61 - 60 x cos C)

Triangle 2 (where A is obtuse):

Given:

B = 50°

b = 5

a = 6

Using the Law of Sines:

sin A / a = sin B / b

sin A / 6 = sin 50° / 5

sin A = (6 x sin 50°) / 5

A = arcsin[(6 x sin 50°) / 5]

A ≈ 44.14° (rounded to the nearest hundredth)

Using the Law of Sines again:

sin C / c = sin B / b

sin C / c = sin 50° / 5

sin C = (c x sin 50°) / 5

Since A is obtuse, C = 180° - A - B

C ≈ 85.86° (rounded to the nearest hundredth)

Using the Law of Cosines:

c² = a² + b² - 2ab x cos C

c² = 6² + 5² - 2(6)(5) x cos C

c² = 36 + 25 - 60 x cos C

c² = 61 - 60 x cos C

The correct probability is indeed 0.25 or 25%.

When heterozygous pink (Pp) and white (pp) flowers are crossed, the Punnett square can be used to determine the probability of offspring having white flowers:

     |   P     p

---------------

 P  |  PP   Pp

---------------

 p  |  Pp   pp

From the Punnett square, we can see that there are four possible combinations of alleles for the offspring: PP, Pp, Pp, and pp.

Out of these four possibilities, only one combination (pp) corresponds to the white flower trait.

Therefore, the probability of an offspring having white flowers is 1 out of 4.

In terms of probability, this can be expressed as:

Probability of white flowers = Number of favorable outcomes / Total number of possible outcomes.

Check Explanation

Step-by-step explanation:

The question is incomplete. But I can explain in a way that the full question can be easily solvable.

Note that the missing part of the question is percentage or fraction of the total college tuition cost that the scholarship covers.

For the sake of clarity, let us assume that the scholarship covers 60% of the total college tuition costs.

This means that Tamara still has to raise 40% of the total college tuition cost herself over the space of 2 years (24 months)

The total college tuition cost = $8240

Amount that Tamara still needs to raise = 40% × 8240 = $3296

She has to raise this amount over 2 years (24 months) on a monthly basis.

So, the amount she has to save monthly over 24 months = (3296/24) = $137.333

So, whatever the fraction or percentage of the total college tuition cost that the scholarship covers, just divide the rest of the college tuition cost after the scholarship has done its part (1 - fraction or 100% - percentage) by 24 months.

The answer is the amount that Tamara needs to save monthly.

x⁴ - 8x² + 17 is the function that represents the fog(x).

To find fog(x), we first need to find g(f(x)), which means we need to substitute the expression for f(x) into the expression for g(x):

g(f(x)) = g(x² - 4)

Now, we can substitute the expression for g(x) into the above expression:

g(f(x)) = (x² - 4)² + 1

Expanding the squared term, we get:

g(f(x)) = x⁴ - 8x² + 17

The 95% confidence interval for the population mean is (47.00, 48.90).

A sample of size n=78 is drawn from a normal population with a standard deviation of σ=5.1. The sample mean is x=47.95.

Using this information, we can estimate the population mean using the formula:

μ = x ± z*(σ/√n)

where μ is the population mean, x is the sample mean, z is the z-score for the desired level of confidence (e.g., 1.96 for a 95% confidence interval), σ is the population standard deviation, and n is the sample size.

Assuming a 95% confidence level, the z-score is 1.96. Plugging in the given values, we get:

μ = 47.95 ± 1.96*(5.1/√78)

Solving for the upper and lower bounds of the confidence interval, we get:

μ = 47.95 ± 0.95

So the 95% confidence interval for the population mean is (47.00, 48.90). This means that if we were to repeat this sampling process many times, we would expect the true population mean to fall within this interval 95% of the time.

The probability that Jess will win only the third game out of three games is 0.144, or 14.4%

To calculate the probability that Jess will win only the third game out of three games, we will use the concept of independent events. In this scenario, we have the following events:

1. Jess loses the first game.
2. Jess loses the second game.
3. Jess wins the third game.

Since the events are independent, we can calculate the probability of this specific sequence occurring by multiplying the probabilities of each individual event:

1. Probability of losing the first game: 1 - 0.4 = 0.6
2. Probability of losing the second game: 1 - 0.4 = 0.6
3. Probability of winning the third game: 0.4

Now, we multiply these probabilities together:

0.6 * 0.6 * 0.4 = 0.144

So, the probability that Jess will win only the third game out of three games is approximately 0.144, or 14.4% when rounded to three decimal places.

2. The average = 1+2+5+3+2+2+5+3/8

3. Therefore, the answer is 2.875, making the mean between 2 and 3

Answer:

The statement that supports the data is the mean distance to his friends' houses is in between 2 and 3 blocks.

Step-by-step explanation:

What is mean, median and mode?

Mean: The average of the given data points.

Median: The central point of the whole data set.

Mode: The number that occurs for the maximum times in the data set.

Given:

Karl records the number of city blocks from his house to each of his friends houses.

Data set for the number of city blocks to eight friends houses:

{1, 2, 5, 3, 2, 2, 5, 3}

The first option: it is given that the maximum number of blocks the Karl lives from his friend is 4, but according to the data set, the maximum number of house blocks should be 5.

Hence, this option is incorrect.

The second option: It is given that the mode shows that Karl has 3 friends who live 3 blocks from him, but according to the given data set Karl has 3 friends who lives 2 blocks from him. Hence the mode is 2.

Hence, this option is incorrect.

The third option: It is given that the minimum distance from Karl's house to a friend's is 2 blocks, but according to the given data set the minimum distance from Karl's house to a friend's is 1 block.

Hence, this option is incorrect.

The fourth option:  It is given that the mean distance to his friend's houses is in between 2 and 3 blocks.

We will find the mean for the given data set.

⇒ Mean = (Sum of all the data points) / (Total number of data points)

⇒ Mean = (1 + 2 + 5 + 3 + 2 + 2 + 5 + 3)/8

⇒ Mean = 23/8

⇒ Mean = 2.875

∴ The mean distance from Karl to his friend's houses is 2.875 which is in between 2 and 3.

Hence, this option is correct.

Therefore, the fourth option which says the mean distance between Karl and his friend's houses is in between 2 and 3 is correct.

The distance from point A to point B is approximately 920 feet.

Let's call the distance from point A to point B as x.

From point A, the angle of elevation to the lighthouse's beacon-light is 8 degrees.

Using the tangent function to find the height of the lighthouse (h):

tan(8) = h/1083

h = 1083 tan(8) ≈ 157.6 feet

From point B, the angle of elevation to the lighthouse's beacon-light is 4 degrees.

Using the tangent function again to find the height of the lighthouse from point B (h'):

tan(4) = h'/(1083-x)

h' = (1083-x) tan(4) ≈ 78.6 - 0.07x

Since the height of the lighthouse should be the same from both points A and B, we can set h = h' and solve for x:

1083 tan(8) = (1083-x) tan(4)

x = 1083 - (157.6/tan(4)) ≈ 920 feet
