Find the volume of each figure. Round to the nearest hundredth. PLEASE HELP SOON :(

Answer:

Step-by-step explanation:

Let's represent the number of marbles Naga has as "n". Since Panav has three times as many marbles as Naga, we can represent the number of marbles Panav has as "3n".

After Naga loses 5 marbles and Panav buys 10 marbles, the number of marbles Naga has is "n - 5" and the number of marbles Panav has is "3n + 10".

Together, they now have more than 105 marbles, so we can write the inequality: (n - 5) + (3n + 10) > 105

Solving this inequality for n:

n - 5 + 3n + 10 > 105

4n + 5 > 105

4n > 100

So, Naga must have had more than 25 marbles initially.

The vectors are equidistant to each other with -2+2i

A vector is a mathematical or geometrical quantity that has both magnitude and direction.  It can be represented as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of the vector is from its tail to its head.

The vectors are

P₁ = (8,3), P₂ = (6, 5), P₃ = (11,8) , P₄ = (9, 10)

u = [(9-8)] , (5-3)]

= (-2,2)   or u = -2 + 2i

Answer:

For Batanta island (B(x)):

The data for B(x) seems to increase linearly, as each value is three times the previous value (2, 6, 18, 54, 162, 486). We can check this by calculating the difference between consecutive values:

6 - 2 = 4

18 - 6 = 12

54 - 18 = 36

162 - 54 = 108

486 - 162 = 324

The differences between consecutive values increase by a factor of 3, which supports the idea that B(x) is a linear function.

For Misool island (M(x)):

The data for M(x) seems to increase exponentially, as each value is roughly twice the previous value (20, 120, 420, 920, 1620, 2520). We can check this by calculating the ratio between consecutive values:

120 / 20 = 6

420 / 120 = 3.5

920 / 420 = 2.19

1620 / 920 = 1.76

2520 / 1620 = 1.56

The ratios between consecutive values decrease as x increases, which supports the idea that M(x) is an exponential function.

For Salawati island (S(x)):

The data for S(x) seems to increase exponentially, as each value is roughly 1.5 times the previous value (38, 81, 124, 167, 210, 253). We can check this by calculating the ratio between consecutive values:

81 / 38 = 2.13

124 / 81 = 1.53

167 / 124 = 1.34

210 / 167 = 1.26

253 / 210 = 1.2

The ratios between consecutive values decrease as x increases, which supports the idea that S(x) is an exponential function.

For W(x):

Based on the given data points, it seems that W(x) is an exponential function. We can check this by calculating the ratio between consecutive values:

48 / 24 = 2

96 / 48 = 2

384 / 96 = 4

768 / 384 = 2

1536 / 768 = 2

The ratios between consecutive values remain constant at 2, which supports the idea that W(x) is an exponential function.

Therefore, of the functions B(x), M(x), and S(x), the same type of function as W(x) is M(x), since both are exponential functions.

X varies directly as y , that x = 9 when y = 3,the value of x when y = 12 by  the constant of Variation , value of x is 36.

X  varies directly as y, it means that there is a constant ratio between x and y. We can express this relationship using the formula:

x = ky

where k is the constant of variation.

To find the value of k, we can use the given information that x = 9 when y = 3. Substituting these values into the formula, we have:

9 = k * 3

Solving for k, we divide both sides of the equation by 3:

k = 9/3

k = 3

Now that we have the value of k, we can find x when y = 12 by substituting it into the formula:

x = 3 * 12

x = 36

Therefore, when y = 12, the corresponding value of x is 36.

if x varies directly as y and we are given that x = 9 when y = 3, we can find the value of x when y = 12 by determining the constant of variation (k) and using the formula x = ky. In this case, the constant of variation is 3, so when y = 12, x equals 36.

The value of cos ø, for the given coordinates (8, 6), is 4/5 in the lowest terms.

To find the value of cosine (cos) ø, we need the coordinates (8, 6) of a point on the unit circle.

The unit circle is a circle with a radius of 1, and the coordinates (8, 6) do not lie on the unit circle. However, we can use these coordinates to calculate the cosine value indirectly.

First, we need to find the hypotenuse (r) of the right triangle formed by the coordinates (8, 6). We can use the Pythagorean theorem:

r = √(8² + 6²) = √(64 + 36) = √100 = 10

Now, we can find the cosine value by dividing the adjacent side length (x-coordinate) by the hypotenuse:

There are  0.09779 grams in 7.4 x 10^19 Atoms of copper.

The number of grams in a given number of atoms of an element, we need to use the concept of molar mass and Avogadro's number.

The molar mass of an element represents the mass of one mole of that element. For copper (Cu), the molar mass is approximately 63.546 grams per mole.

Avogadro's number, denoted as N_A, is the number of atoms or molecules in one mole of a substance. It is approximately 6.022 x 10^23 atoms/molecules per mole.

To calculate the mass of a given number of atoms, we can use the following steps:

Step 1: Determine the number of moles of copper atoms.

Given: 7.4 x 10^19 atoms of copper

Number of moles = (Number of atoms) / (Avogadro's number)

Number of moles = (7.4 x 10^19) / (6.022 x 10^23)

Step 2: Calculate the mass using the molar mass of copper.

Mass = (Number of moles) x (Molar mass)

Mass = (7.4 x 10^19) / (6.022 x 10^23) x 63.546

Now, we can perform the calculations:

Mass ≈ 0.09779 grams

Equity is the difference between what you still owe on your home and what it is worth. This is false.

Equity refers to the ownership value or financial interest that an individual or entity holds in an asset, such as a home. It represents the difference between the market value of the asset and the outstanding balance of any loans or mortgages secured against it.

To be more specific to homeownership, home equity is the portion of the property's value that the homeowner truly owns outright, without any outstanding debts. It is calculated by subtracting the remaining mortgage balance or any other liens on the property from the current market value of the home.

For example, if your home is worth $300,000 and you still owe $200,000 on your mortgage, your equity would be $100,000 ($300,000 - $200,000). This equity can be considered a form of wealth

The length of side KL is approximately 4.8 cm.

To solve this problem, we can use the Law of Sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is equal for all sides of the triangle. In other words:

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

Where a, b, and c are the lengths of the sides of the triangle, and A, B, and C are the measures of the angles opposite those sides.

Using the Law of Sines, we can set up the following proportion:

l/sin(L) = m/sin(M)

Where l is the length of side KL, L is the measure of angle KLM (which is 72 degrees), m is the length of side LM, and M is the measure of angle KML (which we can find by subtracting L from 180 degrees).

M = 180 - L

= 180 - 72

= 108 degrees

Now we can substitute the given values into the proportion and solve for l:

l/sin(72) = 5.9/sin(108)

l = sin(72) * (5.9/sin(108))
