Using the bearing and trigonometry in the problem, the distance of the waterfall from the lake is 7.94km

To determine the distance between the waterfall and the lake, we can use trigonometry and the given information about the bearing and the distance in a south direction.

To find the distance between the waterfall and the lake, we can use the concept of right triangles and trigonometric functions.

Since the bearing is given as 236°, we can subtract this angle from 180° to find the angle formed by the south direction and the line connecting the lake and the waterfall:

180° - 236° = -56°

Now, we can consider the south direction as the reference direction (0°) and the line connecting the lake and the waterfall as the hypotenuse of a right triangle.

Using the cosine function, we can calculate the length of the side adjacent to the angle (-56°), which represents the distance between the waterfall and the lake:

cos θ = adjacent / hypothenuse

Adjacent = Hypotenuse * cosθ

Let's substitute the values into the formula:

Adjacent  = 14.2 km * cos(-56°)

To calculate the cosine of -56°, we can use the fact that the cosine function is an even function:

cos(-56°) = cos(56°)

Adjacent side = 14.2 cos(56)

Adjacent side = 7.94km

Answer:

The waterfall is approximately 8.91 km away from the lake

Step-by-step explanation:

To find the distance between the waterfall and the lake, we can use trigonometry and the given information about the bearing and the southward direction.

Since the waterfall is 14.2 km south of the lake, the line connecting the waterfall and the lake forms a right triangle with the south direction being the adjacent side, the distance between them being the hypotenuse, and the angle formed between them being the bearing of 236°.

To find the distance between the waterfall and the lake, we can use the cosine function, which relates the adjacent side, hypotenuse, and angle:

cos(236°) = adjacent side / hypotenuse

Let's denote the distance between the waterfall and the lake as "d." The adjacent side represents the southward direction.

cos(236°) = d / 14.2 km

Solving for "d":

d = cos(236°) * 14.2 km

Using a calculator:

d ≈ -8.91 km

Since distance cannot be negative, we take the absolute value:

|d| ≈ 8.91 km

Therefore, the waterfall is approximately 8.91 km away from the lake.

The location of point A''' after the three transformations would be (-4, 1).

To determine the location of point A''', we need to apply the three transformations (reflection over the y-axis, reflection over the x-axis, and rotation of 180°) to point A.

When a point is reflected over the y-axis, the x-coordinate is negated while the y-coordinate remains the same.

So, the reflection of point A (-4, 1) over the y-axis would be (4, 1).

When a point is reflected over the x-axis, the y-coordinate is negated while the x-coordinate remains the same. So, the reflection of point (4, 1) over the x-axis would be (4, -1).

When a point is rotated 180°, the x-coordinate and y-coordinate are both negated. So, the rotation of point (4, -1) by 180° would be (-4, 1).

The graph that best represents these characteristics is the one that shows an increasing curve with a flattened slope and is shifted upward. Option C

The function C(x) = (1/4)√x + 2 represents the side length of the smaller granola bar, where x is the area of the larger granola bar in square inches. To determine which graph shows C(x), we need to analyze the characteristics of the function.

First, let's consider the behavior of the function C(x) = (1/4)√x + 2:

Square Root Function: The term √x indicates that the function involves the square root of x. This means that as x increases, C(x) will also increase, but at a decreasing rate.

Scaling Factor: The coefficient (1/4) scales the square root of x. It affects the steepness of the function and causes C(x) to increase more slowly compared to a simple square root function.

Vertical Shift: The constant term (+2) shifts the entire function vertically upward by 2 units. This means that the graph will be raised by 2 units compared to a standard square root function.

Based on these characteristics, we can conclude that the graph of C(x) will be an increasing curve with a flattened slope compared to a simple square root function, and it will be shifted upward by 2 units.

Among the answer choices, the graph that best represents these characteristics is the one that shows an increasing curve with a flattened slope and is shifted upward. Without the actual graphs provided, it is difficult to specify the exact choice, but it should exhibit these features described above.

It is essential to refer to the available graphs or visually analyze the functions to determine the correct graph that shows C(x). Option C is correct.

Let's start by finding the values of a, b, and c using logarithmic properties:

Taking the logarithm of both sides of [tex]\large\sf\:3^a = 9^b\\[/tex], we get:

[tex]\large\sf\:\log_3(3^a) = \log_3(9^b)\\[/tex]

Applying the power rule of logarithms, we can bring down the exponents:

[tex]\large\sf\:a\log_3(3) = b\log_3(9)\\[/tex]

Since [tex]\large\sf\:\log_3(3) = 1[/tex] and [tex]\large\log_3(9) = 2\\[/tex], we simplify to:

[tex]\large\sf\:a = 2b\\[/tex] ---- (1)

Similarly, taking the logarithm of both sides of [tex]\sf\:9^b = 27^c\\[/tex], we get:

[tex]\large\sf\:b\log_3(9) = c\log_3(27)\\[/tex]

Using the values of [tex]\sf\:\log_3(9)\\[/tex] and [tex]\sf\:\log_3(27)\\[/tex] as before, we have:

[tex]\large\sf\:b(2) = c(3)\\[/tex]

Simplifying, we get:

Now, let's substitute the value of b from equation (1) into equation (2):

[tex]\large\sf\:2(2b) = 3c\\[/tex]

[tex]\large\sf\:4b = 3c\\[/tex]

Rearranging, we find:

[tex]\large\sf\:c = \frac{4b}{3}\\[/tex] ---- (3)

We now have expressions for a, b, and c in terms of b. Let's substitute these into the expression [tex]\large\sf\:\frac{a}{b} + \frac{b}{c} + \frac{c}{a}\\[/tex]:

[tex]\large\sf\:\frac{a}{b} + \frac{b}{c} + \frac{c}{a} = \frac{2b}{b} + \frac{b}{\frac{4b}{3}} + \frac{\frac{4b}{3}}{2b}\\[/tex]

Simplifying further, we get:

[tex]\large\sf\:\frac{2}{1} + \frac{3}{4} + \frac{2}{3}\\[/tex]

Finding the common denominator and combining the fractions, we have:

[tex]\large\sf\:\frac{24}{12} + \frac{9}{12} + \frac{8}{12}\\[/tex]

Adding the fractions together, we obtain:

[tex]\large\sf\:\frac{24 + 9 + 8}{12} = \frac{41}{12}\\[/tex]

Therefore, [tex]\large\sf\:\frac{a}{b} + \frac{b}{c} + \frac{c}{a} = \frac{41}{12}\\[/tex].

The formula for sin(a - b) is sin(a)cos(b) - cos(a)sin(b).

To find the formula for sin(a - b), we can use the identity for cosine of a sum of angles, which states that:

cos(a + b) = cos(a)cos(b) - sin(a)sin(b)

We can rearrange this equation to solve for sin(a - b):

cos(a + b) = cos(a)cos(b) - sin(a)sin(b)

cos(a + b) = cos(a)cos(b) + (-1)(sin(a)sin(b)) [multiplying sin(b) by -1]

cos(a + b) = cos(a)cos(b) + sin(a)(-sin(b)) [rearranging terms]

cos(a + b) = cos(a)cos(b) - sin(a)sin(b) [sin(b) can be replaced by -sin(b)]

Comparing this equation with the given identity, we can see that:

sin(a - b) = sin(a)cos(b) - cos(a)sin(b)

Therefore, the formula for sin(a - b) is sin(a)cos(b) - cos(a)sin(b).

Area of a triangle = 1/2 × Base × Height

= 1/2 ×(√10²-6²)×6

Answer:

To find the answer, we can use the formula:

number of won games / total number of games played = percentage won

Let x be the total number of games played. We know that the percentage won is 65%, or 0.65 as a decimal. So we can set up the equation:

number of won games / x = 0.65

To solve for x, we can cross-multiply:

number of won games = 0.65x

We want to find a whole number value for x that makes sense. One way to do this is to try each answer choice and see if it gives a whole number value for the number of won games. Let's start with choice A:

If the team played 22 games, then the number of won games is:

number of won games = 0.65 * 22 = 14.3

This is not a whole number value, so we can rule out choice A.

We can repeat this process for each answer choice. When we try choice C, we get:

number of won games = 0.65 * 18 = 11.7

This is also not a whole number value, so we can rule out choice C.

When we try choice D, we get:

number of won games = 0.65 * 14 = 9.1

This is also not a whole number value, so we can rule out choice D.

Therefore, the only remaining answer choice is B, which gives us:

number of won games = 0.65 * 20 = 13

This is a whole number value, so the team could have played 20 games in total last season.

Approximately 273 cubes with a side length of 1/2 inch will be needed to fill the prism.

To determine the number of cubes with a side length of 1/2 inch needed to fill the prism, we need to calculate the volume of the prism and divide it by the volume of a single cube.

The given dimensions of the pencil box are:

Length: 6 1/2 inches

Width: 3 1/2 inches

Height: 1 1/2 inches

To find the volume of the prism, we multiply the length, width, and height:

Volume of the prism = Length [tex]\times[/tex] Width [tex]\times[/tex] Height

[tex]= (6 1/2) \times (3 1/2) \times (1 1/2)[/tex]

First, we convert the mixed numbers to improper fractions:

[tex]6 1/2 = (2 \times 6 + 1) / 2 = 13/2[/tex]

[tex]3 1/2 = (2 \times 3 + 1) / 2 = 7/2[/tex]

[tex]1 1/2 = (2 \times 1 + 1) / 2 = 3/2[/tex]

Now we substitute the values into the formula:

Volume of the prism [tex]= (13/2) \times (7/2) \times (3/2)[/tex]

[tex]= (13 \times 7 \times 3) / (2 \times 2 \times 2)[/tex]

= 273 / 8

≈ 34.125 cubic inches.

Next, we calculate the volume of a single cube with a side length of 1/2 inch:

Volume of a cube = Side length [tex]\times[/tex] Side length [tex]\times[/tex] Side length

[tex]= (1/2) \times (1/2) \times (1/2)[/tex]

= 1/8

To find the number of cubes needed to fill the prism, we divide the volume of the prism by the volume of a single cube:

Number of cubes = Volume of the prism / Volume of a single cube

= (273 / 8) / (1/8)

= 273
