The area of the sector is A = π cm² and amplitude is a = 0.75 cm

Given data ,

The area of a sector is given by the formula:

A = (1/2) x r² x θ

where r is the radius of the sector and θ is the central angle in radians.

On simplifying , we get

A = π cm²

r = 1.5 cm

Substituting these values into the formula, we get:

π = (1/2) x (1.5)² x θ

π = (3/4) x θ

Solving for θ, we get:

θ = (4/3) x π

The amplitude of the sector is half of the radius, so:

amplitude = (1/2) x 1.5 cm = 0.75 cm

Hence , the amplitude of the sector is 0.75 cm

The cardioid is recognized as a particular instance of an epicycloid and is formed by (x2 + y2 + an x)2 = a2(x2 + y2).

A two-dimensional plane figure called a cardioid features a heart-shaped curvature. The Greek word "cardioid," which meaning "heart," is the source of the word "cardioid." Thus, it is referred to as a heart-shaped curve.

The polar pattern of a cardioid microphone gives it its name. It is classified as a directional microphone since only noises from the front and sides may be picked up by it, and the direction has an impact on the sound image that is recorded.

the third term of the geometric sequence with first term = 1/4 and common ratio r = -2 is 1

We have a geometric sequence in which the first term is \(\frac{1}{4}\) and the common ratio is -2.

We have to find the third term of this geometric sequence.

The formula to find the \(n^{th}\) term of a geometric sequence with first term \(a_{1}\) and common ratio r is -

\(a_{n} =a_{1} r^{n-1}\)

In our question, \(a_{1}\) = \(\frac{1}{4}\)  and r = -2 and n =3.

Substituting the values, we get -

\(a_{3} =\frac{1}{4}(-2)^{3-1} = \frac{1}{4} (-2)^{2} =\frac{1}{4}\times4=1\)

Hence, the third term of the geometric sequence with first term = 1/4 and common ratio r = -2 is 1.

The amount of interest for the year was 3,770 cents, and the regular price of the electric drill that Pamela bought before the discount was 21,927 cents

Interest = P x R x T.

Where:

P = Principal amount (the beginning balance).

R = Interest rate

T = Number of time periods

In this case, we are given that;

Principal amount (P) = $580

Interest rate (R) = 6,5 %

Time = 1 year

Hence, The amount of the interest = 6,5% of $580

                                                     = 0.065 × $580

                                                     = $37.7

1 dollar = 100 cents

Hence, $37.7 = 37.7 × 100 cents equal to 3,770 cents

P = (1 – d) x

Where,

P = Price after discount

D = discount rate

X = regular price

In this case, we are given that:

P = $32.89

D = 85% = 0,85

Hence, the regular price:

P = (1 – D) x

32.89 = (1 – 0.85) X

32.89 = 0.15X

X = 32.89/0.15

X= 219.27

1 dollar = 100 cents

Hence, $219.27 = 219.27 × 100 cents equal to 21,927 cents

The current dosage rate for cationic polymer for a treatment plant running at 4,883 gpm and feeding 85 pounds per day is approximately 1.74 mg/L.

Dosage rate is the amount of chemical added to the water in a given unit of time. In this case, the dosage rate for cationic polymer can be calculated as follows:

Dosage rate = (85 lb/day) / (4,883 gpm x 60 min/hour x 8.34 lb/gal)
Dosage rate = 0.0002585 lb/gal
Dosage rate = 1.74 mg/L (since 1 lb/gal is equivalent to 119.83 mg/L)

If your p-value is 0.11 and the significance level is 0.05, you would conclude that there is insufficient evidence to reject the null hypothesis. In other words, you cannot establish a statistically significant relationship between the variables you are studying.

To explain this further, the p-value (0.11) represents the probability of observing the data, assuming that the null hypothesis is true. A smaller p-value indicates stronger evidence against the null hypothesis. The significance level (0.05) serves as a threshold to determine whether the p-value is small enough to reject the null hypothesis.

If the p-value is less than or equal to the significance level, you would reject the null hypothesis and conclude that there is a statistically significant relationship between the variables. However, in this case, the p-value (0.11) is greater than the significance level (0.05), which means that the probability of observing the data is not low enough to reject the null hypothesis.

Therefore, you cannot establish a statistically significant relationship between the variables, and the observed results could be due to chance or random variation.

Describe equation.

Two expressions joined by an equal sign form a mathematical statement known as an equation.

An equation is, for instance, 3x - 5 = 16. We can solve this equation and determine that the value of the variable x is 7.

According to the Given question:

x³ + 6x² + 11x +6

This pattern of coefficients 1, 6, 11, 6 is actually one that you are likely to encounter frequently.

For demonstration reasons, let's see what occurs if we begin by using the typical technique for resolving a general cubic:

We can use a linear substitution, t = x + b/3a, to simplify any cubic of the form ax3 + bx2 + cx + d, resulting in a cubic in the form a + b + et + f without a quadratic term.

This is the most straightforward type of Tschirnhaus transformation.

In our example, a = 1 and b = 6, so we want t = x + 2.

Note that:

=  + 6+ 12x +8

So we find:

+ 6+ 11x +6 =   − (x + 2)

=  - t

= t ( - 1)

= t(t − 1)(t + 1)

= (x+2)(x+1)(x+3)

n the given problem, we have an implicit equation ln(x+y+z) = x+2y+3z that defines z as a function of x and y. We are given the values dy = (-1, 5, -3).

To find the derivative dy/dx, we can use the total derivative formula and apply it to the implicit equation. The total derivative is given by dy/dx = - (∂F/∂x)/(∂F/∂y), where F = ln(x+y+z) - x - 2y - 3z.

Differentiating F partially with respect to x and y, we have (∂F/∂x) = 1/(x+y+z) - 1 and (∂F/∂y) = 1/(x+y+z) - 2.

Plugging in the given values of dy = (-1, 5, -3), we can calculate dy/dx = - (∂F/∂x)/(∂F/∂y) = -(-1)/(5-2) = 1/3.

Therefore, the derivative dy/dx is equal to 1/3 based on the given information. It's important to note that this calculation assumes that the partial derivatives (∂F/∂x) and (∂F/∂y) are not zero at the given point (z.y.a).

The distance from the point (4, 1,-2) to the line x = 1 + t, y = 3 - 2t, z = 4-3t is 10 / sqrt(14), and the distance from the point (0, 1, 3) to the line x = 2t, y = 6-2t, z = 3 + t is 7 / 3.

To find the distance from a point to a given line in space, we can use the formula d = |(P - Q) × v| / |v|, where P is the given point, Q is a point on the line, and v is the direction vector of the line.

For problem 69, we have the line x = 1 + t, y = 3 - 2t, z = 4-3t and the point P = (4, 1,-2). We can choose any point on the line to be Q, so let's choose Q = (1, 3, 4) (when t=0). Then, the direction vector of the line is v = <1, -2, -3>.

Substituting these values into the distance formula, we get d = |(P - Q) × v| / |v| = |(3, -2, -6) × (1, -2, -3)| / sqrt(14) = 10 / sqrt(14).

For problem 70, we have the line x = 2t, y = 6-2t, z = 3 + t and the point P = (0, 1, 3). Let's choose Q = (2, 4, 4) (when t=1) as a point on the line, and then the direction vector of the line is v = <2, -2, 1>.

Substituting these values into the distance formula, we get d = |(P - Q) × v| / |v| = |(-2, -3, -1) × (2, -2, 1)| / 3 = 7 / 3.

Therefore, the distance from the point (4, 1,-2) to the line x = 1 + t, y = 3 - 2t, z = 4-3t is 10 / sqrt(14), and the distance from the point (0, 1, 3) to the line x = 2t, y = 6-2t, z = 3 + t is 7 / 3.

When the radius of the snowball is 4 and shrinks at a rate of 2 inches per hour then the rate of change of the surface area s is equal to 64π in²/hr

As the radius r is shrinking at the rate of two inches per hour, it can be represented as;

dr/dt = -2 in / hr

Here, the negative sign represents the shrinking of the snowball with time t.

The surface area of a sphere can be represented by the formula;

S = 4πr²

Now we differentiate S with respect to t by keeping radius (r) as a variable as follows;

dS/dt = d/dt (4πr²)

dS/dt = 4π (d/dt) (r²)

dS/dt = 4π × 2r (dr/dt)

Putting the value of r = 4 and calculated value of dr/dt = -2 in the equation as follows;

dS/dt = 4π × 2(4)(-2)
