What is exponential growth?

Exponential growth happens once the larger in size you're the quicker you grow that causes you to even larger in size. it's the expansion characterised by interest, or growth. it's known as exponential growth as a result of it will solely be delineate mathematically by inserting time within the exponent or power of the bottom. Population then is adequate to the population at the current times some discretional range to the facility of the expansion rate times the time. The discretional range is sometimes two then the expansion rates is given because the reciprocal of the doubling time.

Main body:

initial population = 25

Total generation = 20

growth rate = 0.2

General formula of exponential function = aˣ

here a = 25 and x = 0.2

⇒25⁰°²

= 1.9

hence total population = 25+2 = 27

So it is clear that in 19 to 20 generation , growth will be highest.

To find the area of the region bounded by the parabola y = 4x², the tangent line to this parabola at (2, 16), and the x-axis, we will integrate the area between the curve and the x-axis on the interval (0,2) and then subtract the area of the triangle formed by the tangent line, x-axis, and the vertical line x=2.

Here's the complete solution:Step 1: Find the equation of the tangent line at (2,16)The derivative of y = 4x² is:y' = 8xThus, the slope of the tangent line at (2,16) is:y'(2) = 8(2) = 16The point-slope form of the equation of a line is:y - y₁ = m(x - x₁)Using point (2,16) and slope 16, the equation of the tangent line is:y - 16 = 16(x - 2)y - 16 = 16x - 32y = 16x - 16Step 2: Find the x-coordinate of the intersection between the parabola and the tangent line.To find the x-coordinate, we equate the equations:y = 4x²y = 16x - 16Substituting the first equation into the second gives:4x² = 16x - 16Simplifying, we get:4x² - 16x + 16 = 04(x - 2)² = 0x = 2Since the x-coordinate of the point of intersection is 2, this is the right endpoint of our integration interval.Step 3: Integrate the region bounded by the parabola and the x-axis on the interval (0,2)We need to integrate the curve y = 4x² on the interval (0,2):∫(0 to 2) 4x² dx= [4x³/3] from 0 to 2= (4(2)³/3) - (4(0)³/3)= (32/3)Thus, the area between the curve and the x-axis on the interval (0,2) is 32/3.Step 4: Find the area of the triangle formed by the tangent line, x-axis, and the vertical line x=2To find the area of the triangle, we need to find the height and base.The base is the vertical line x=2, so its length is 2.The height is the distance between the x-axis and the tangent line at x=2, which is 16. Thus, the area of the triangle is:1/2 * base * height= 1/2 * 2 * 16= 16Step 5: Subtract the area of the triangle from the area of the region bounded by the parabola and the x-axis on the interval (0,2)Area of the region = (32/3) - 16= (32 - 48)/3= -16/3Therefore, the area of the region bounded by the parabola y = 4x², the tangent line to this parabola at (2, 16), and the x-axis is -16/3.

The parabola is defined by the equation \(y = 4x².\)

We need to find the area of the region bounded by this parabola, the tangent line to this parabola at (2, 16), and the x-axis.

This is illustrated in the figure below: Let's first find the equation of the tangent line at (2, 16).

The derivative of y = 4x² is:y' = 8x

\(y = 4x² is:y' = 8x\)

The slope of the tangent line at \((2, 16) is therefore: y'(2) = 8(2) = 16\)

The equation of the tangent line is therefore:y - 16 = 16(x - 2) => y = 16x - 16

\(y - 16 = 16(x - 2) => y = 16x - 16\)We can now find the intersection points of the parabola and the tangent line by solving the system of equations:\(4x² = 16x - 16 => 4x² - 16x + 16 = 0 => (2x - 4)² = 0\)

Therefore, x = 2 is the only intersection point.

This means that the region is bounded by the x-axis on the left, the parabola above, and the tangent line below.

To find the area of this region, we need to integrate the difference between the parabola and the tangent line from x = 0 to x = 2.

This gives us the area of the shaded region in the figure above.

Using the equations of the parabola and the tangent line, we have:\(y = 4x²y = 16x - 16\)

The difference between these two functions is:\(y - (16x - 16) = 4x² - 16x + 16\)

To find the area of the region, we need to integrate this function from x = 0 to x = 2.

That is, we need to compute the following definite integral: \(A = ∫[0,2] (4x² - 16x + 16) dxIntegrating term by term, we get: A = [4/3 x³ - 8x² + 16x]₀² = [4/3 (2)³ - 8(2)² + 16(2)] - [4/3 (0)³ - 8(0)² + 16(0)] = [32/3 - 32 + 32] - [0 - 0 + 0] = 32/3\)

Therefore, the area of the region bounded by the parabola \(y = 4x², the tangent line to this parabola at (2, 16), and the x-axis is 32/3 square units.\)

The given statements discuss properties of a vector space V, particularly focusing on the property of a vector w that satisfies u + w = w + u = u for all u in V.

Based on the provided information, it can be inferred that this property implies certain elementary properties of vector addition and scalar multiplication in V. Specifically, it suggests that adding the zero vector to any vector w results in w, and that subtracting a vector u from itself yields the zero vector.

Additionally, it suggests that the sum of a vector u and its additive inverse, denoted as -u, equals the zero vector. These conclusions can be derived using the axioms of vector spaces, which provide the foundational rules for vector operations.

Given vector field, F(x, y, z) = y cos (xy) i + x cos (xy) j – sin z k To calculate the curl of F, we need to take the curl of each component and subtract as follows,∇ × F = ( ∂Q/∂y - ∂P/∂z ) i + ( ∂P/∂z - ∂R/∂x ) j + ( ∂R/∂x - ∂Q/∂y ) k...where P = y cos(xy), Q = x cos(xy), R = -sin(z)

Now we calculate the partial derivatives as follows,

∂P/∂z = 0, ∂Q/∂y = cos(xy) - xy sin(xy), ∂R/∂x = 0...

and,

∂P/∂y = cos(xy) - xy sin(xy), ∂Q/∂z = 0, ∂R/∂y = 0

Therefore,

∇ × F = (cos(xy) - xy sin(xy)) i - sin(z)j

The curl of F is given by:

(cos(xy) - xy sin(xy)) i - sin(z)j.

To state whether F is conservative, we need to determine if it is a conservative field or not. This means that the curl of F should be zero for it to be conservative. The curl of F is not equal to zero. Hence, the vector field F is not conservative. Let C be the curve joining the origin (0,1,-1) to the point with coordinates (1, 2V2,2) defined by the following parametric curve:

r(t) = n* i + t}j + tcos atk, 15t52.

The curve C is defined as follows,r(t) = ni + tj + tk cos(at), 0 ≤ t ≤ 1Given vector field, F(x, y, z) = y cos(xy) i + x cos(xy)j – sin zk Using the curve parameterization, we get the line integral as follows,∫CF.dr = ∫10 F(r(t)).r'(t)dt...where r'(t) is the derivative of r(t) with respect to t

= ∫10 [(t cos(at))(cos(n t)) i + (n cos(nt))(cos(nt)) j + (-sin(tk cos(at)))(a sin(at)) k] . [i + j + a tk sin(at)] dt

= ∫10 [(t cos(at))(cos(n t)) + (n cos(nt))(cos(nt)) + (-a t sin(at) cos(tk))(a sin(at))] dt

= ∫10 [(t cos(at))(cos(n t)) + (n cos(nt))(cos(nt)) - a^2 (t/2) (sin(2at))] dt

= [sin(at) sin(nt) - (a/2) t^2 cos(2at)]0^1

= sin(a) sin(n) - (a/2) cos(2a)

The vector field F(x, y, z) = y cos(xy) i + x cos(xy)j – sin zk is given. Firstly, we need to calculate the curl of F. This involves taking the curl of each component of F and subtracting. After calculating the partial derivatives of each component, we get the curl of F as (cos(xy) - xy sin(xy)) i - sin(z)j. Next, we need to determine whether F is conservative. A conservative field has a curl equal to zero. As the curl of F is not equal to zero, it is not a conservative field. In the second part of the problem, we have to calculate the scalar line integral of the vector field F. dr along the curve C joining the origin to the point with coordinates (1, 2V2, 2). We use the curve parameterization to calculate the line integral. After simplifying the expression, we get the answer as sin(a) sin(n) - (a/2) cos(2a).

The curl of the given vector field F(x, y, z) = y cos(xy) i + x cos(xy)j – sin zk is (cos(xy) - xy sin(xy)) i - sin(z)j. F is not conservative as its curl is not zero. The scalar line integral of the vector field F along the curve C joining the origin to the point with coordinates (1, 2V2,2) is sin(a) sin(n) - (a/2) cos(2a).

The equation -4 x -1/4 = 1 illustrates the commutative property of multiplication.

The commutative property of multiplication states that changing the order of the factors does not change the product. In other words, for any two numbers a and b, the product of a x b is equal to the product of b x a.

In the given equation, we have -4 x -1/4 = 1. By applying the commutative property of multiplication, we can rearrange the factors:

-4 x -1/4 = -1/4 x -4

Since the commutative property of multiplication holds true, we can rewrite the equation as:

-1/4 x -4 = 1

The result of multiplying -1/4 by -4 is indeed 1. This confirms that the equation satisfies the commutative property of multiplication.

In conclusion, the equation -4 x -1/4 = 1 demonstrates the commutative property of multiplication, which states that the order of the factors can be changed without affecting the product.
