The area enclosed by the parametric curve and the y-axis is 0.7542 square units.

The parametric curve is defined by \(\(x = t^2 - 2t\)\) and \(\(y = \sqrt{t}\)\).

Now, let's calculate the area enclosed by the curve and the y-axis:

\(\[ \text{Area} = \int_{0}^{c} |y| \, dt \]\)

Here,  \(\(c\)\)  is the upper bound of the domain, which is the value of \(\(t\)\) where the curve intersects the y-axis.

At the y-axis, the x-coordinate is 0, so we set \(\(x = 0\)\) in the equation for the parametric curve:

\(\[ x = 0\\ t^2 - 2t = 0\]\)

Solving for t:

\(\[ t^2 - 2t = 0 \\ t(t - 2) = 0 \]\)

So, t=0, or t=2. Since we are considering the domain where  \(\(t \geq 0\)\), the upper bound of the domain c is \(\(t = 2\)\).

Now, we'll integrate the absolute value of y with respect to t from 0 to 2:

\(\[ \text{Area} = \int_{0}^{2} |\sqrt{t}| (2t-t)\, dt \]\)

Since \(\(y = \sqrt{t}\)\) is positive in the given domain, the absolute value is not necessary, and we can simplify the integral:

\(\[ \text{Area} = \int_{0}^{2} \sqrt{t} (2t-t)\, dt \]\)

Now, integrate:

\(\[ \text{Area} = [\frac{4}{5}t^{5/2} -\frac{4}{3}t^{3/2} \Big|_{0}^{2} \]\\\)

\(\[ \text{Area} = [\frac{4\times\4\sqrt{2}}{5} -\frac{4\times\2\sqrt{2}}{3}] -0\)

\(\[ \text{Area} = \frac{8\sqrt{2}}{15}\)

\(\[ \text{Area} =0.7542 \ sq\ units\)

So, the area enclosed by the parametric curve and the y-axis is 0.7542 square units.

Answer:

\(\frac{3x^2}{y}\)

The time the Matt has been running is 44 seconds and the catchup distance is 352 meters

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

Hanson's speed = 4mps

Matt's speed = 8mps

Represent the time the Hanson has been running with x

The speed is calculated using

Speed = Distance/Time

So, we have the following representations

Hanson's speed = Distance/Time

Matt's speed = Distance/Time

This gives

4 = Distance/(44 + x) -- for Hanson

8= Distance/x for Matt

So, we have

Distance = 4(44 + x)

Distance = 8x

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

8x = 4(44 + x)

Open the brackets

8x = 176 + 4x

Evaluate the like terms

4x = 176

So, we have

x = 44

Recall that

Distance = 8x

So, we have

Distance = 8 x 44

Evaluate

Distance = 352

Hence, the time is 44 seconds and the distance is 352 meters

Answer:

The time it takes the rock to reach the canyon floor is approximately 4 seconds.

Step-by-step explanation:

The equation representing the height h (in feet) of an object t seconds after it is dropped is:

\(h=-16t^{2}+h_{0}\)

Here, h₀ is the initial height of the object.

It is provided that a small rock dislodges from a ledge that is 255 ft above a canyon floor.

That is, h₀ = 255 ft.

So, when the rock to reaches the canyon floor the final height will be, h = 0.

Compute the time it takes the rock to reach the canyon floor as follows:

\(h=-16t^{2}+h_{0}\)

\(0=-16t^{2}+255\\\\16t^{2}=255\\\\t^{2}=\frac{255}{16}\\\\t^{2}=15.9375\\\\t=\sqrt{15.9375}\\\\t=3.99218\\\\t\approx 4\)

If 2sinθ = 6/5, then the value of cos (90 - θ) will be 3/5. Then the correct option is A.

We can use the fact that:

sinθ = cos(90 - θ)

to convert the sine to cosine (but the angles won't stay the same unless it's 45 degrees).

If 2sinθ = 6/5.

Step-by-step explanation:

lol im an rsm kid too. but i hope these are right,

first i'm gonna start with 263 c.

AREA = 4a^2 * 3a^2 divided by 2.  

12a^4 divided by 2 = 6a^4.

AREA = 6a^4

Perimeter you can find with the pythag. th.

(4a^2) ^2 + (3a^2 ) ^2 = c^2

16a^4 + 9a^4 = c^2

, the missing side is 5a^2

therefore the perimeter is 4a^2 + 3a^2 + 5a^2 = 12a^2

Answer:

x=18

Step-by-step explanation:

A triangle ALWAYS have overall angles of 180 degrees.

When we look at this triangle, it should come to familiarity that this is a 45 45 90 triangle. This is a special type of isosceles right triangle.

But without knowing this, we can still solve this problem.

Since the triangles' overall angle is 180 and we know 45 and 45 of the two other angles, let's subtract that together to find out the overall angle where we are trying to find x.

180-45-45=90

This means that the expression 4x+18 is equal to 90, since that's the leftover angle amount.

Let's solve that equation now.

4x+18=90         Let's get rid of the 18 by subtracting it on both sides.

    -18  -18

4x=72               Isolate the x by dividing both by 4.

x=18

In this problem, x is equal to 18.

Answer:

X=18

Step-by-step explanation:

we know that (4x+18) = 90 degrees because the 45 degrees plus 45 degrees is 90 and 90+90 equals a full 180 triangle.

From here you just solve out 4x+18=90

4x+18=90

-18 -18 Subtract 18 from both sides

4x=72. Divide both sides by 4

x=18

Given data:

The first equation is 2x+3y=-12.

The second equation is x+y=9.

The second equation can be written as,

y=9-x

Substitute the above value in second equation.

2x+3(9-x)=-12

2x+27-3x=-12

-x=-39

x=39

The value of y is,

39+y=9

y=-30.

Thus, the value of x is 39, and the value of y is -30.

The food intake is proportional to body surface area. So, a 40 kg dog should eat 4.85 liters of dog food per week. Therefore, the correct answer is option a. 5 litres.

Since food intake is proportional to body surface area, we calculate the amount of food required for a 40 kg dog as:

(food for 10 kg dog) x (surface area of 40 kg dog) / (surface area of 10 kg dog)

To calculate the surface area, we can use the formula for the surface area of a sphere, which is 4πr^2, where r is the radius of the sphere. We can assume that the dogs are roughly spherical, so we can use their weight to estimate their radius using the formula:

radius = (weight / density)^(1/3)

where the density of a dog is approximately 1 g/cm^3.

For the 10 kg dog:

radius = (10,000 g / 1 g/cm^3)^(1/3) = 21.54 cm

surface area = 4π(21.54 cm)^2 = 5823.47 cm^2

For the 40 kg dog:

radius = (40,000 g / 1 g/cm^3)^(1/3) = 33.60 cm

surface area = 4π(33.60 cm)^2 = 14122.57 cm^2

Now we can plug in the values and solve for the amount of food required for the 40 kg dog:

(food for 10 kg dog) x (surface area of 40 kg dog) / (surface area of 10 kg dog) = (2 liters) x (14122.57 cm^2) / (5823.47 cm^2)

= 4.85 liters

Therefore, a 40 kg dog should eat about 4.85 liters of dry dog food per week, which is closest to 5 liters.

The probability that the mean weight of the sample babies would be less than 3631 grams is 0.1591 or 15.91%.

The mean weight of the babies (μ) = 3685 grams.

The variance (σ²) = 330625.

Therefore, the standard deviation (σ) = √330625 = 575.

The sample size (n) = 113.

The sample mean = μ - 3685 grams.

The sample standard deviation (s) = σ/√n = 575/√113 = 54.09145.

We are asked to find the probability that the mean weight of the sample babies is less than 3631 grams, that is,

P(X < 3631)  = P(Z < {(3631 - 3685)/54.09145})

Using the formula: Z = (x - μ)/s,

or, P(Z < -0.9983) = 0.1591 or 15.91%.

From the table of area under the z-score.

P(X < 3631) can also be calculated using calculator function:

Normalcdf(-100000000,3631,3685,54.0195), which gives the value 0.1591 or 15.91%.

Answer:

3. 8 feet

Step-by-step explanation:

To find the horizontal distance (x) in feet, we can use the following steps:

Step 1: Determine the vertical height that the box has been lifted.

The difference between the two points is:

9 ft - 3 ft = 6 ft.

Therefore, the box has been lifted 6 feet.

Step 2: Use the slope of the ramp to find the horizontal distance (x).

The slope of the ramp is given as 3/4. This means that for every 3 feet the ramp rises vertically, it moves 4 feet horizontally. We can set up a proportion to solve for x:

3/4 = 6/x

We can cross-multiply to get:

3x = 24

Dividing both sides by 3 gives us:

x = 8

Therefore, the horizontal distance (x) is 8 feet.
