The half-life of the substance is 1.94 years.

The exponential decay formula aids in determining the exponential drop, which is a rapid reduction over time. To calculate population decay, half-life, radioactivity decay, and other phenomena, one uses the exponential decay formula. F(x) = a \((1-r)^{x}\) is the general form.

Here

a = the initial amount of substance

1-r is the decay rate

x = time span

The correct form of the equation is given as:

\(a=a_{0}\)×\((0.7)^{t}\)

where t is an exponent of 0.7 since this is an exponential decay of 1st order reaction

Now to solve for the half life, this is the time t in which the amount left is half of the original amount, therefore that is when:

a = 0.5 a0

Substituting this into the equation:

0.5 \(a_{0}=a_{0}\)×\((0.7)^{t}\)

0.5 = \((0.7)^{t}\)

Taking the log of both sides:

t log 0.7 = log 0.5

t = log 0.5 / log 0.7

t = 1.94 years

The half life of the substance is 1.94 years.

The expression for arctan(4/3) in terms of π is a tan(4/3) / π.

To express arc tan(4/3) in terms of π, we can use the relationship between the trigonometric functions and the unit circle.

The tangent function (tan) is defined as the ratio of the length of the side opposite an angle to the length of the adjacent side in a right triangle. The inverse tangent function, arctan, gives the angle whose tangent is a given value.

In this case, arctan(4/3) represents the angle whose tangent is 4/3. To express this angle in terms of π, we can consider the unit circle.

For arctan(4/3), we can construct a right triangle in the unit circle with the opposite side equal to 4 and the adjacent side equal to 3.

Using the Pythagorean theorem, we can calculate the length of the hypotenuse:

hypotenuse² = opposite² + adjacent²

hypotenuse² = 4² + 3²

hypotenuse²= 16 + 9

hypotenuse²= 25

hypotenuse = 5

Now, let's denote the angle whose tangent is 4/3 as θ. In the right triangle we constructed, the sine of the angle θ is given by opposite/hypotenuse, which is 4/5, and the cosine of the angle θ is given by adjacent/hypotenuse, which is 3/5.

Since the sine is positive and the cosine is positive in the first quadrant of the unit circle, we can conclude that arctan(4/3) corresponds to an angle in the first quadrant.

Therefore, arctan(4/3) can be expressed as:

arctan(4/3) = θ

Since θ corresponds to an angle in the first quadrant, we can write:

arctan(4/3) = θ = tan(4/3)

Note that a tan(4/3) is an angle measure in radians. To express it in terms of π, we need to divide atan(4/3) by π:

arctan(4/3) = θ = tan(4/3) / π

So, the expression for arctan(4/3) in terms of π is a tan(4/3) / π.

The quadrant in which 0 lies, given that tan θ > 0 and sin θ < 0, is Quadrant IV. The quadrant in which 0 lies when tan θ > 0 and sin θ < 0 is Quadrant IV.

Using a point on the coordinate plane, we can represent a positive tangent as follows: the slope of a line drawn from the origin (0,0) to a point on the coordinate plane is positive. Using a point on the coordinate plane, we can represent a negative sine as follows: the y-coordinate of a point on the coordinate plane is negative.To determine the quadrant in which 0 lies, we must look at the sign of the coordinates for 0. The point (0,0) has both an x and a y coordinate of zero. The origin is located at the center of the coordinate plane. Therefore, the point (0,0) is in every quadrant.In the first quadrant, both the x and y coordinates are positive.In the second quadrant, the x coordinate is negative and the y coordinate is positive.In the third quadrant, both the x and y coordinates are negative.In the fourth quadrant, the x coordinate is positive and the y coordinate is negative. Because the origin has a negative y-coordinate, it lies in Quadrant IV. Hence, the answer is Quadrant IV.

1. Factor out the greatest common factor (GCF) from the coefficients.

2. Split the middle coefficient into two factors that add to the middle coefficient and multiply to the last coefficient.

1. First, identify the GCF of the coefficients, which is 1. Since there is no GCF, this step can be skipped.

2. Next, split the middle coefficient (17) into two factors that add to the middle coefficient and multiply to the last coefficient.

Since 17 = 8 + 9, we can use 8 and 9 as our two factors.

3. Group the terms by the common factors.

We can group the first and last term together (6x2 + 5) and the middle term separately (17x).

4. Factor out the common factor, which is x, from the first and last group. This gives us x(6x + 5).

5. Lastly, factor the remaining quadratic expression (6x + 5).

Since 8 and 9 are the two numbers that add to the middle coefficient and multiply to the last coefficient, we can use them as our two factors. This gives us (6x + 8)(x + 9).

Therefore, the factored form of 6x2 + 17x + 5 is x(6x + 8)(x + 9).

where;

(a, b) is the center of the circle

r is the radius of the circle

Given the following diameter = 12 units

radius = 12/2 = 6 units

If the centre lies on the y-axis, the center will be at (0, 3)

Substituting into the formula, we will have (x-0)² + (y-3)² = 6² equivalent to x²+ (y-3)² = 36

The work done by the force F on a particle moving counterclockwise around the closed path C is π(\(e^4\) − 1).

To use Green's theorem to calculate the work done by the force F on a particle moving counterclockwise around a closed path C, we need to first calculate the curl of F:

curl F = (∂Ey/∂x − ∂(ex−9y)/∂y) k = (2ex − 9)k

where i, j, and k are the unit vectors in the x, y, and z directions, respectively.

Next, we need to parameterize the closed path C. In this case, the path is given by r = 2cos(θ), where θ varies from 0 to 2π. We can parameterize this path as:

x = 2cos(θ)

y = 2sin(θ)

We can then use Green's theorem to calculate the work done by F:

∮C F · dr = ∬R (curl F) · dA

where R is the region enclosed by C and dA is the area element.

Substituting in the values we have calculated, we get:

∮C F · dr = ∬R (2ex − 9)k · dA

The region R is a circle with radius 2, so we can use polar coordinates to evaluate the integral:

∬R (2ex − 9)k · dA = ∫θ=0 2π ∫r=0 2 (2e^(r cosθ) − 9)r dr dθ

Evaluating this integral, we get:

Professor A's salary is 31% of Professor B's salary(D).

Professor A's salary can be determined by combining the given information. We know that Professor A's salary is 69% less than Professor B's salary, which means it is 31% of Professor B's salary (100% - 69% = 31%).

Additionally, we are told that Professor A's salary is 169% of Professor E's salary plus another 69% (169% + 69% = 238%) and that Professor A's salary is -69% of Professor B's salary.

Combining these two equations, we can deduce that 238% of Professor E's salary equals -69% of Professor B's salary. Simplifying this, we find that Professor A's salary is 31% of Professor B's salary (238% - 69% = 169%, and 169% = 31% + 100%).

The smallest possible inside length of the cubical steel tank that can hold 275 liters of water is approximately 0.640 meters.

The side length of the cube is found by converting the volume of water from liters to cubic meters, as the unit of measurement for the side length is meters.

Given that the volume of water is 275 liters, we convert it to cubic meters by dividing it by 1000 (1 cubic meter = 1000 liters):

275 liters / 1000 = 0.275 cubic meters

Since a cube has equal side lengths, we find the side length by taking the cube root of the volume. In this case, we find the cube root of 0.275 cubic meters:

The solution to the integral is:\(∫ 1/(sinh(x)) dx = (1/2) ln|sinh(x) + sinh(x)^2| + C.\)

To find the integral of \(1/(sinh(x))\), we can use the substitution \(u = sinh(x)\), which implies\(du/dx = cosh(x)\) and\(dx = du/cosh(x)\). Substituting these into the integral, we get:

\(∫ 1/(sinh(x)) dx = ∫ 1/u * du/cosh(x)\)

\(= ∫ cosh(x)/u * du\)

Now, we can use the identity\(cosh^2(x) - sinh^2(x) = 1\)to replace\(cosh(x)^2\)with \((sinh(x)^2 + 1)\)in the integrand:

\(∫ (sinh(x)^2 + 1)/u * du\)

\(= ∫ sinh(x)^2/u * du + ∫ 1/u * du\)

The first integral can be rewritten using the identity \(sinh^2(x) = (cosh(2x) - 1)/2:\)

\(∫ (cosh(2x) - 1)/(2u) * du\)

\(= (1/2)∫ cosh(2x)/u * du - (1/2)∫ du/u\)

\(= (1/2) ln|u + sinh(x)| - (1/2) ln|u| + C\)

\(= (1/2) ln|sinh(x) + sinh(x)^2| + C\)

Therefore, the solution to the integral is:

\(∫ 1/(sinh(x)) dx = (1/2) ln|sinh(x) + sinh(x)^2| + C\)
