Answer:

To find out how much yogurt is needed to fill the cone, we need to use the formula for the volume of a cone:

V = (1/3) * π * r^2 * h

Where:

- `V` is the volume of the cone

- `π` is a mathematical constant equal to about 3.14159

- `r` is the radius of the cone

- `h` is the height of the cone

Plugging in the known values, we get:

V = (1/3) * π * 3^2 * 5

V = (1/3) * π * 9 * 5

V = 15π

Therefore, the volume of the cone is 15π cubic centimeters. So you would need 15π cubic centimeters of yogurt to fill the cone. Alternatively, you could use an approximation of π = 3.14 or 22/7 to estimate the amount of yogurt needed, which would give you approximately 47.1 cubic centimeters of yogurt.

Answer:

28°

Step-by-step explanation:

Theorem: the exterior angle of a triangle is equal tobthe sum of opposite interior angles of the triangle

therefore,

55 = unknown angle + 27

let the unknown angle be x

55 = x + 27

isolating x

x = 55 - 27

x = 28

thus, the missing angle is 28°

The test statistic in this case is 3.

To test the hypothesis H0: μ = 100, where the sample size is n = 100, σ = 10, and the sample mean is 103, we can calculate the test statistic using the z-test.

The formula for the z-test statistic is:

z = (x - μ) / (σ / √n)

x is the sample mean,

μ is the population mean under the null hypothesis (H0),

σ is the population standard deviation, and

n is the sample size.

Plugging in the values from the given information, we have:

x = 103 (sample mean)

μ = 100 (population mean under H0)

σ = 10 (population standard deviation)

n = 100 (sample size)

Substituting these values into the formula, we can calculate the z-test statistic:

z = (103 - 100) / (10 / √100)

z = 3 / (10 / 10)

z = 3

Thus, the appropriate answer is 3.

Answer:

B = 4

Step-by-step explanation:

Given that B is directly proportional to A then the equation relating them is

B = kA ← k is the constant of proportionality

To find k use the condition B = 3 when A = 18 , then

3 = 18k ( divide both sides by 18 )

k = \(\frac{3}{18}\) = \(\frac{1}{6}\)

B = \(\frac{1}{6}\) A ← equation of proportion

When A = 24, then

B = \(\frac{1}{6}\) × 24 = 4

The length of the curve is \(e^ \pi\) - 1 units.

To find the length of the curve \(x = e^t cos(t), y = e^tsin(t)\), where 0 ≤ t ≤ π.

In this case, the curve is defined by the equations \(x = e^t cos(t)\) and \(y = e^t sin(t)\), where t is the variable that represents the parameter along the curve.

To find the length of this curve, we can use a formula known as the arc length formula.

L = ∫[a,b] √〖[dx/dt]〗² + 〖[dy/dt]² dt

where L represents the length of the curve, a and b are the starting and ending values of the parameter, dx/dt and dy/dt are the derivatives of x and y with respect to t.

To find the derivatives dx/dt and dy/dt. Using the product rule and chain rule of differentiation, we get:

\(dx/dt = e^tcos(t) - e^t sin(t) dy/dt = e^t sin(t) + e^t cos(t)\)

Substituting these expressions into the arc length formula and simplifying, we get: L = ∫[0,π] \(e^tdt\)

Integrating this expression with respect to t, we get: L = \(e^\pi\)- 1

So the length of the curve is \(e^ \pi\) - 1 units.

Answer:

Step-by-step explanation:

We can use the proportionality relationship between force and acceleration, which is given as:

force = constant × acceleration

Let's call the constant of proportionality k. Then we can write:

40 N = k × 4 m/s^2

Solving for k, we get:

k = 40 N / 4 m/s^2 = 10 Ns^2/m

Now we can use this value of k to find the force required for an acceleration of 9 m/s^2:

force = k × acceleration = 10 Ns^2/m × 9 m/s^2 = 90 N

Therefore, the force required for an acceleration of 9 m/s^2 is 90 N.

Therefore, if there were 40 dogs and the ratio stayed the same, there would be 120 cats at the pet daycare.

If the ratio of dogs to cats stays the same, then the ratio of dogs to cats in the two situations will be equal.

The initial ratio of dogs to cats is:

dogs : cats = 20 : 60

= 1 : 3

To maintain the same ratio, the new number of cats (C) can be found by setting up the proportion:

dogs : cats = 40 : C

Using the initial ratio of dogs to cats, we can substitute and simplify:

1 : 3 = 40 : C

Cross-multiplying gives:

C = (3 x 40) / 1

The total surface area of the prism = 182.4 mm².

The total space occupied by an object's surfaces is referred to as its surface area.

The formulas we will learn in this post make it simple to determine the various surface areas that various 3D shapes in geometry have.

The surface area is divided into two categories:

Curved or laterally oriented surface area.

Total area of surface.

Now in the given question,

Surface area of the triangle = 1/2 × 6 ×8 = 24mm²

Surface area of the rectangle = 5.6 × 6 = 33.6mm²

Surface area of the second rectangle = 5.6 × 8 = 44.8mm²

Surface area of the second triangle = 1/2 × 6 × 8 = 24mm²

Surface area of the base rectangle= 5.6 × 10 = 56mm²

Step-by-step explanation: parallel lines have the same slope

In the field of complex numbers (C), a straight line in the plane (CR²) is considered F-definable if it can be represented by an equation of the form ax + by + c = 0, where a, b, and c are elements of the subfield F. Similarly, a circle in the plane (OC R2) is F-definable if it can be represented by an equation of the form x² + y² + a = 0.

In the mathematical framework of complex numbers, which extends the real numbers, we consider a subfield F of the complex numbers (C). Within this context, we define the notion of F-definable objects in the plane. Specifically, a straight line in CR² is F-definable if there exists an equation of the form ax + by + c = 0, where the coefficients a, b, and c belong to the subfield F.

Similarly, we extend this definition to circles in the plane. A circle centered at the origin (O) with radius R in R² is F-definable if there exists an equation of the form x² + y² + a = 0, where a is an element of the subfield F.

The concept of F-definability allows us to study the geometric properties of lines and circles using algebraic equations within a specific subfield. By restricting the coefficients of the equations to elements of the subfield F, we can explore different subfields and analyze the properties and relationships of lines and circles defined by those equations. This notion has applications in various areas of mathematics, including algebraic geometry and complex analysis, where the study of geometric objects through algebraic equations plays a fundamental role.

The number of subjects who participated in the study is 20.

To determine the number of subjects who participated in the study, we need to understand the relationship between the degrees of freedom (df) and the sample size in a t-test.

In a matched-subjects experiment, participants are typically matched based on certain characteristics or variables to create pairs or groups. Each pair or group is then exposed to different conditions or treatments, and the differences within each pair or group are analyzed.

This type of design is often used to minimize individual differences and increase the precision of the study.

In a matched-subjects t-test, the degrees of freedom are calculated based on the difference scores between the pairs or groups. The formula to calculate the degrees of freedom is:

df = n - 1

Where 'n' represents the number of pairs or groups.

In a matched-subjects design, each pair contributes one degree of freedom.

Given that the t statistic has a df of 19, we can set up the equation:

19 = n - 1

Solving for 'n', we add 1 to both sides:

19 + 1 = n - 1 + 1

20 = n

The equation of the tangent line to the curve x = 7sin(t), y = t² + t at the point (0, 0) is y = (1/7)x. The slope of the tangent line at (0, 0) is 1/7.

To find the equation of the tangent line, we need to find the derivative of y with respect to x and evaluate it at the point (0,0), which corresponds to t=0. First, we need to eliminate the parameter t by solving the x equation for t in terms of x

x = 7 sin t => t = arcsin(x/7)

Substituting this expression for t into the y equation gives

y = [arcsin(x/7)]² + arcsin(x/7)

To find the derivative of y with respect to x, we use the chain rule and the derivative of arcsin(x/7) which is 1/√(49-x²):

dy/dx = [2arcsin(x/7) + 1] * (1/√(49-x²)) * (1/7)

At the point (0,0), we have x=0, and thus

dy/dx = [2arcsin(0/7) + 1] * (1/√(49-0²)) * (1/7) = 1/7

So the slope of the tangent line at (0,0) is 1/7.

Finally, we use the point-slope form of a line to write the equation of the tangent line

y - 0 = (1/7)(x - 0)

Simplifying

y = (1/7)x

Therefore, the equation of the tangent line to the curve x = 7 sin t, y = t² + t at the point (0,0) is y = (1/7)x.
