The chef should use approximately 80 milliliters of the first brand (5% vinegar) and (240 - 80) = 160 milliliters of the second brand (11% vinegar) to make 240 milliliters of dressing that is 9% vinegar.

Let's assume the chef uses x milliliters of the first brand (5% vinegar) and (240 - x) milliliters of the second brand (11% vinegar).

To find the amounts of each brand needed, we can set up an equation based on the vinegar content:

(0.05x + 0.11(240 - x)) / 240 = 0.09

Simplifying the equation:

0.05x + 0.11(240 - x) = 0.09 * 240

0.05x + 26.4 - 0.11x = 21.6

-0.06x = -4.8

x = -4.8 / -0.06

x ≈ 80

Step-by-step explanation:

You are pushing a 40.0 kg crate across the floor. what force is needed to start the box moving from rest if the coefficient of static friction is 0.288?

The force needed to start the box moving from rest if the coefficient of static friction is 0.288 is 112.9 N.

Force is defined as an influence that causes an object to undergo a change in motion. Static friction: Static friction is a type of friction that must be overcome to start an object moving. The force needed to start the box moving from rest can be determined using the formula below:

Force of friction = Coefficient of friction × Normal force where: Coefficient of friction = 0.288

Normal force = Weight = mass × gravity (g) = 40.0 kg × 9.8 m/s² = 392 N

Force of friction = 0.288 × 392 N = 112.896 N (approx)

The force of friction is 112.896 N (approx) and since the crate is at rest, the force needed to start the box moving from rest is equal to the force of friction.

Force needed to start the box moving from rest = 112.896 N (approx) ≈ 112.9 N (rounded to one decimal place)

It will take 5 seconds for the waste to hit the ground.

We know that the bird releases the waste from a height of 400ft, so the height equation is:

\(h(t) = -16t^2 + 400\)

The waste will hit the ground when its height is equal to zero, so we just need to solve the quadratic equation:

\(h(t) = 0 = -16t^2 + 400\\\\16t^2 = 400\\\\t^2 = 400/16 = 25\\\\\)

Now we can apply the square root in both sides:

Answer: For the first one all you have to do is 11x11 and you will get 121. For number 2 do (-2)^3x(-6) and you will get 48. I hope this helps. I do suggest using a calculator tho

Step-by-step explanation:

Answer:

10. 121

12. 48

Step-by-step explanation:

10.

So, when it comes to squares, you always multiply the number by itself (unless it is in parenthesis, but that's another question for another time).

In this case, you have a -11 behind the square.

Pro Tip: Any time there is a single number being squared, it will ALWAYS be positive-no matter if it is negative or positive (e.g., 5x5=25 and -5 x -5=25)

So, you would multiply the -11 by itself, or -11 x -11, which equals 121.

Pro Tip: Whenever you are multiplying any double digit number with 11, you separate the two numbers in the double digit, add them together and put that sum in between the two numbers (e.g., 12 x 11 = 1(1+2)2 = 132, or 16 x 11 = 1 (1+6) 6 = 176.

12.

With this, you have to be a little more precise.

Let's look at the first parenthesis.

When you are doing cubes, you multiply the same number 3 times against itself:

In this case, -2 x -2 x -2 = -8.

(If you are wondering why it's negative, think about this: when a negative number is squared, it becomes positive--like -5 x -5 = 25-- but if you multiply a positive number by a negative one, you get a NEGATIVE number again-- -5 x -5 = 25 x -5 = -125)

Now, looking at the second parenthesis, there isn't anything attached to it, so you just multiply with it.

So, -8 x -6 = 48.

The surface area A(S) is 64√2 - 128/3

What is a parametric equation?

A parametric equation is a mathematical representation of a curve or surface in terms of one or more parameters. Instead of defining the curve or surface directly in terms of x and y (or x, y, and z for three-dimensional surfaces), parametric equations express the coordinates as functions of one or more parameters.

What is surface area?

Surface area is a measure of the total area that covers the outer part of a three-dimensional object or surface. It represents the sum of all the areas of the individual faces or surfaces that make up the object.

To find the area of the surface given by the parametric equations, we first need to calculate the cross product of the partial derivatives of the vector function r(u, v). Then we will integrate the magnitude of the cross product over the parameter domain D.

Let's calculate the partial derivatives of r(u, v) with respect to u and v:

∂r/∂u = <2u, v, 0>

∂r/∂v = <0, u, v>

Now, let's calculate the cross product of these partial derivatives:

ru × rv = <2u, v, 0> × <0, u, v>

= <v(v), 0, -2u(u)>

The magnitude of ru × rv is |ru × rv| = √(v² + 4u²).

To find the surface area, we need to integrate |ru × rv| over the parameter domain D, which is given as 0 ≤ u ≤ 2 and 0 ≤ v ≤ 4.

A(S) = ∫∫D |ru × rv| dA

= ∫[0,4]∫[0,2] √(v² + 4u²) dudv

Integrating this expression will give us the surface area A(S).

A(S) = ∫[0,4]∫[0,2] √(v² + 4u²) dudv

We can start by integrating with respect to u:

∫[0,2] √(v² + 4u²) du

To integrate this expression, we can make a substitution by letting w = v² + 4u². Then dw/du = 8u, which implies du = (1/8u)dw.

When u = 0, w = v² + 4(0)² = v², and when u = 2, w = v² + 4(2)² = v² + 16.

The integral becomes:

∫[v², v²+16] √w (1/8u) dw

Since u = (w - v²) / (4u), we can rewrite the integral as:

(1/8) ∫[v², v²+16] √w / u dw

Now we can integrate with respect to w:

(1/8) ∫[v², v²+16] √w / ((w - v²) / (4u)) dw

(1/8) ∫[v², v²+16] (4u/ (w - v²)) √w dw

Let's simplify further:

(1/2) ∫[v², v²+16] (u/ (w - v²)) √w dw

We can now evaluate this integral with respect to w. The limits of integration are v² and v² + 16.

(1/2) ∫[v², v²+16] (u/ (w - v²)) √w dw

(1/2) u ∫[v², v²+16] (1/ √w) dw

Integrating (1/ √w) with respect to w gives 2√w.

(1/2) u [2√w] evaluated from v² to v²+16

(1/2) u [2√(v²+16) - 2√v²]

Now, let's evaluate the outer integral with respect to v:

∫[0,4] (1/2) u [2√(v²+16) - 2√v²] dv

To evaluate this integral, we substitute u = 2u:

∫[0,4] (1/2) 2u [2√(v²+16) - 2√v²] dv

∫[0,4] u [2√(v²+16) - 2√v²] dv

Now we can integrate with respect to v:

u ∫[0,4] [2√(v²+16) - 2√v²] dv

To evaluate this integral, we can apply the power rule for integration and simplify:

u [v√(v²+16) - (4/3)v\(^{3/2}\)] evaluated from 0 to 4

Now we substitute the limits of integration:

u [(4√(4²+16) - (4/3)4\(^{3/2}\)]

Simplifying further:

u [(4√(16+16) - (4/3)4\(^{3/2}\)]

u [(4√32 - (4/3)4\(^{3/2}\)]

We can simplify the expression inside the square root:

4√32 = 4√(16 * 2) = 4√16 * √2 = 4 * 4√2 = 16√2

The expression becomes:

u [(16√2 - (4/3)4\(^{3/2}\)]

Simplifying the second term:

(4/3)4\(^{3/2}\) = (4/3) * 4 * √4 = (4/3) * 4 * 2 = 32/3

The expression becomes:

u [(16√2 - 32/3)]

Now, let's substitute the limits of integration:

u [(16√2 - 32/3)] evaluated from 0 to 4

Plugging in the upper limit:

4 [(16√2 - 32/3)] = 4 * (16√2 - 32/3) = 64√2 - 128/3

Finally, let's subtract the value at the lower limit:

0 [(16√2 - 32/3)] = 0

Therefore, the surface area A(S) is:

A(S) = 64√2 - 128/3

Note: The units of area will depend on the units of the original parametric equations (x, y, z).

Step-by-step explanation:

Yeah

Answer:

It is K.

Step-by-step explanation:

A large t-statistic indicates a greater difference between the sample means and provides stronger evidence for a significant difference between the populations.

The t-statistic is a measure of the difference between two sample means relative to the variability within the samples. When the population means are different, the difference between the sample means will tend to be larger, which will result in a larger numerator in the t-statistic formula. The larger the difference between the sample means, the greater the evidence for a difference between the populations. In contrast, if the population means are similar, the difference between the sample means will be smaller, resulting in a smaller numerator and a weaker test of significance.

The denominator of the t-statistic formula is the standard error of the mean, which measures the variability of sample means around the population mean. If the sample size is large enough, the standard error of the mean will be small, resulting in a smaller denominator and a larger t-statistic. Therefore, when the population means are different, a larger t-statistic would be expected due to a combination of a larger numerator and a smaller denominator.

In summary, If the population means are different, a large t-statistic would be expected.

Answer:

The area of sector is 4.71mi^2

Step-by-step explanation:

The area of the sector that Marla needs to remove is (3/2)π square feet.

Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object. Area is measured in terms of standard areas. Therefore, they are relative to each other.

We normally use a square of unit length as its size. That unit can be 1 cm, 1 meter, etc.

Now when we want to find surface area of some object, then the value we get tells us that you can fit this many unit sided squares on that object's surface.

We are given that;

Central angle = 60°

The radius of the circle = 3 feet.

Now,

To find the area of the sector that Marla needs to remove, we can use the formula:

A = (θ/360)πr^2

where A is the area of the sector, θ is the central angle of the sector, r is the radius of the circle, and π is pi (approximately 3.14).

Plugging in the values we know, we get:

A = (60/360)π(3)^2 A

= (1/6)π(9) A

= (3/2)π

Therefore, the area of the fabric will be (3/2)π square feet.
