The amount of carrot that Fluffy the bunny had to eat at night, given the proportion eaten in the morning, is 1 / 10 of a carrot.

After Fluffy the bunny ate 1 / 2 of the carrot in the morning, the amount of the carrot that would be left is 1 / 2 of the carrot or 0. 5 of the carrot.

This means that if 2 / 5 of the carrot is left to eat at the end of the day, the amount of carrot that Fluffy the bunny had to eat at night was:

= 1 / 2 -  2 / 5

= 0. 5 - 0 . 4

= 0 . 1 of the carrot

In fractions, 0. 1 is:

= 0 . 1 / 1

= 1 / 10 of the carrot

The unit rate for the skydiver falls is 200 feet per second.

The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other words, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined.

Given the graph shows the distance a skydiver falls over time,

and graph titled distance a skydiver falls has time (seconds) on the x-axis, and distance (feet) on the y-axis.

The line passes from (0, 0) and (1.5, 300)

the point (1.5, 300) says that a skydiver covers 300 feet in 1.5 seconds

to find the unit rate we need to calculate the speed,

speed = distance/time

distance covered = 300 feet

time taken = 1.5 seconds

speed = 300/1.5

speed = 200 feet per second

Hence the unit rate is 200 feet per second.

The Laplace transform of the given integral equation is:

[tex]F(s) = L{f(t)} = ∫(0 to ∞) e^(-st)f(t) dt\\f(t) = L^-1{F(s)} = ∫(0 to ∞) e^(st)F(s) ds[/tex]

Given the equation

[tex]f(t) = 4t + 16sin(t) + ∫(0 to t) e^(t-u)f(u) du[/tex],

we can take the Laplace transform of both sides:

[tex]F(s) = L{f(t)} = L{4t + 16sin(t)} + L{∫(0 to t) e^(t-u)f(u) du}[/tex]

Using the properties of the Laplace transform, we have:

[tex]L{4t} = 4/s^2\\L{16sin(t)} = 16/s^2 + 16s\\L{∫(0 to t) e^(t-u)f(u) du} = F(s)L{e^(t-u)} \\= F(s)e^(-u)(1/s-1)^u|(0,t) \\= F(s)(e^(-t)/s - 1)[/tex]

By substituting these results into the equation, we get:

[tex]F(s) = (4/s^2 + 16/s^2 + 16s) + (F(s)(e^(-t)/s - 1))[/tex]

Solving for F(s) we get:

[tex]F(s) = (4/s^2 + 16/s^2 + 16s)/(1 - e^(-t)/s)[/tex]

To find f(t) we need to take the inverse Laplace transform of F(s)

[tex]f(t) = L^-1{F(s)} = L^-1{(4/s^2 + 16/s^2 + 16s)/(1 - e^(-t)/s)}[/tex]

By using the Law of Syllogism, a conditional should be used to write this statement "If a baby has a fever, then the baby is sick. If a baby is sick, then the baby must be brought to the hospital" as follows: B. If the baby has a fever, then the baby must be brought to the hospital.

In Mathematics, the Law of Syllogism is sometimes referred to as reasoning by transitivity and it states that if two (2) statements are true, then a third true statement can be logically derived.

Mathematically, the Law of Syllogism follows a specific pattern and can be represented by the following conditional statements:

Conditional statement 1: If P, then Q (P ↔ Q).

Conditional statement 2: If Q, then R (Q ↔ R.

The required center of the circle's equation is (h, k) = (-4, 1), and the radius, r = 7.

The equation of a circle with center (h,k) and radius r is :

r² = (x−h)² + (y−k)²

To convert the equation to standard form, we complete the square for both x and y. To do this, we add and subtract the square of half the coefficient of the x term and the y term, respectively:

x² + 8x + (8/2)² - 2y + 2(8/2)(1/2)y - 2y + (2/2)² = 32

Simplifying, we get:

x² + 8x + 16 - 2y + y + 1 = 32

Now we can combine like terms:

x² + 8x + 16 + y - 2y + 1 = 32

x² + 8x + y + 17 = 32 + 17

x² + 8x + y = 49

Now we have the equation in standard form:

(x + 4)² + (y - 1)² = 49

The center of the equation is (h, k) = (-4, 1), and the radius, r = 7.

Answer: Option 4

Step-by-step explanation:

in option 4, the image is reflected, so it is a reflection.

The amount of wood needed to rebuild the frame in meters is 24.58 meters.

The whole number of boards supplied is 13

Given the dimension of the long jump pit as shown in the image attached.

In order to determine the amount of wood needed to rebuild the frame in meters, you need to calculate the perimeter of the long jump pit.

The perimeter of a rectangle is given by:

P = 2(L + W)

where L is the length and W is the width

From the image: L = 9.54 meters and W = 2.75 meters

P = 2(9.54+2.75)

P = 2(12.29)

P = 24.58 meters

Thus, the amount of wood needed to rebuild the frame in meters is 24.58 meters

How many boards did the volunteers supply round your calculations to the nearest hundredth:

No. of boards = 24.58 / 1.8287 = 13.44

Each side of the park has a length of 11 units.

In mathematics, a side is a geometrical shape's aspect. Lines (line segments) and points make up the shapes we see (vertices). The vertices of these line segments connect to form a shape. These line segments are referred to as sides.

To calculate the length of each side, we can use the distance formula:  d = √((x2 - x1)2 + (y2 - y1)2). For example, to calculate the length of the side between (26.5, 12), and (38.5, 7), the equation would be d = √((38.5 - 26.5)2 + (12 - 7)2) = √(120 + 52) = √172 = 11.208.

On solving the provided question, we can say that - the interest ant the end of the time will be 45

Multiplying the principal by the interest rate, time, and other factors yields simple interest. Simple return equals principle times interest times hours is the marketed formula. It is easiest to compute interest using this formula. A percentage of the principle balance is how interest is most commonly computed. For instance, he will only pay his portion of the 100% interest if he borrows $100 from a buddy and promises to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you lend money, you must charge interest. Most of the time, interest is expressed as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.

The packaging 2 uses more material than packaging 1

From the question, we have the following parameters that can be used in our computation:

Package = 12 cans

Material 1 = 3 rows of 4

Material 2 = 6 rows of 2

The packaging uses more material has the greater perimeter

The perimeter is then calculated as

Perimeter = 2 * (Rows + Column)

substitute the known values in the above equation, so, we have the following representation

Material 1 Perimeter = 2 * (3 + 4)

Material 1 Perimeter = 14

Material 2 Perimeter = 2 * (6 + 2)

Material 2 Perimeter = 16

This means that the material 2 uses more material because 16 is greater than 14
