The perimeter of Koch's snowflake fractal will be infinite.

Koch's snowflake fractal is created by adding triangular bumps to the sides of an equilateral triangle at progressively smaller scales. At each stage, the number of sides of the resulting figure increases by a factor of 4, and the perimeter of the figure increases as well.

To see how the perimeter changes as bumps are added to all sides of the figure, we can use the fact that each bump adds a segment of length 1/3 to the original side. So if we start with a triangle of side length 1 and add a bump to each side, the new perimeter is:

P = 3(1 + 1/3) = 4

Now we have a figure with 12 sides. If we add a bump to each of these sides, the new perimeter is:

P = 12(1 + 1/3 + 1/9) = 16/3

In the next stage, we have 48 sides, and each side has a length of 1/3^2, so the new perimeter is:

P = 48(1 + 1/3 + 1/9 + 1/27) = 64/3

At each stage, we can see that the perimeter is multiplied by a factor of 4/3. So if we carry on this process forever, the perimeter of Koch's snowflake fractal will be infinite.

Astha's account was greater than the amount of money in Henry's account is:

5700 + 100x > 75x

Let's start by finding the total amount of money deposited by Astha and Henry after x weeks.

Astha deposited $100 into her account each week for x weeks, so the total amount she deposited is 100x.

Similarly, Henry deposited $75 into his account each week for x weeks, so the total amount he deposited is 75x.

To find the inequality that represents the situation when the amount of money in Astha's account was greater than the amount of money in Henry's account, we need to compare the total amount of money each of them deposited.

Astha started with $5,700 and deposited $100 each week for x weeks, so the total amount of money in her account after x weeks is:

5700 + 100x

Henry started with zero dollars and deposited $75 each week for x weeks, so the total amount of money in his account after x weeks is

To determine how many times a day we would need to fill the container shown below, we need to calculate its capacity in cubic centimeters. Let's assume that the container is a rectangular prism with dimensions of 30 centimeters (length) x 20 centimeters (width) x 25 centimeters (height). The formula for calculating the volume of a rectangular prism is:

Volume = length x width x height

Plugging in the values we have, we get:

Volume = 30 cm x 20 cm x 25 cm

Volume = 15,000 cubic centimeters

Therefore, the container has a capacity of 15,000 cubic centimeters. To determine how many times we would need to fill it each day, we need to divide the amount of pellets and hay we feed the okapi daily (5,024 cubic centimeters) by the capacity of the container (15,000 cubic centimeters):

5,024 / 15,000 = 0.3356

This means that we would need to fill the container approximately 0.3356 times a day, which is not a practical answer. We need to round this up to the nearest whole number.

The options given to us are 80 times, 40 times, 16 times, and 4 times. Out of these options, the closest whole number to 0.3356 is 1, which means we would need to fill the container once a day.

Therefore, the answer is that we would need to fill the container shown below 1 time a day to feed the okapi their daily amount of pellets and hay.

Answer: 26/100   OR     0.26  (I would put the answer as a fraction)

Step-by-step explanation:

We need both fractions to have the same denominator before we add them. The denominator of 6/100 is 100. The denominator of 2/10 is 10. We need to turn 10 into 100. To do that, we can do 10*10. This gives us 100. However what we do to the bottom must be done to the top therefore we have 20/100 + 6/100

Now the two fractions can be added together. 20/100 + 6/100 = 26/100.

Normally we would simplify this down to 13/50 but if you want it unsimplified 26/100 would be your answer.

a) The resulting true speed of the boat is approximately 5.39 m/s.

b) The compass direction of the boat is 21.8° south of east.

c) The distance downstream the boat will land on the shore if the river is 800 meters wide is 320 meters.

a) To find the true speed of the boat, we can use the Pythagorean theorem. Since the boat's speed is 5 m/s due east and the current's speed is 2 m/s due south, we can treat these as perpendicular vectors. The true speed can be found using the formula:

True Speed = √((5 m/s)² + (2 m/s)²) = √(25 + 4) = √29 ≈ 5.39 m/s

b) To find the compass direction of the boat, we can use the inverse tangent function. The angle θ can be calculated using:

θ = arctan(opposite/adjacent) = arctan(2 m/s / 5 m/s) ≈ 21.8°

Since the boat is headed east and the current is pushing it south, the true direction is 21.8° south of east.

c) To find the distance downstream where the boat will land, we first need to calculate the time it takes to cross the river. The boat's speed across the river (due east) is 5 m/s and the width of the river is 800 meters. The time taken to cross the river is:

Time = Distance / Speed = 800 m / 5 m/s = 160 seconds

Now, we can use the time to find the distance downstream by multiplying the current's speed (2 m/s) by the time:

Distance downstream = 2 m/s × 160 s = 320 meters

So, the boat will land 320 meters downstream from its starting point on the opposite shore.

Using the formula V = k*T/P to get the volume, the required volume in the given situation is 1.77L.

The measurement of three-dimensional space is volume. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units.

Volume and the notion of length are connected.

The area that any three-dimensional solid occupies is known as its volume.

These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.

So, the volume can be obtained using the equation:

V = k*T/P

The value of the constant k is:

K = PV/T = 16N/cm²*2.2L/340K = 0.104N*L*K⁻¹*cm⁻²

We can now determine the volume when:

T = 408 K

P = 24 N/cm²

V = k*T/P = 0.104N*L*K⁻¹*cm⁻²*408K/21Ncm = 1.77L

x(t) = 57t
y(t) = -7t
z(t) = -3

To find the parametric equations for a line in the direction of the vector 57 - 7 and through the point (0, 0, - 3), we can use the vector form of the equation of a line:

r = r0 + tv

where r is a point on the line, r0 is the given point (0, 0, -3), t is a parameter, and v is the direction vector (57, -7, 0).

Substituting the given values, we have:

r = (0, 0, -3) + t(57, -7, 0)
