The graph of y = 3ex ex − 5 has a horizontal asymptote of y = 3 and a vertical asymptote of x = -3/5.

The equation y = 3ex ex − 5 can be rewritten as y = 3x2ex − 5. In order to find the horizontal and vertical asymptotes of this function, we must first find its degree of the numerator and denominator. The numerator is a second degree polynomial while the denominator is a first degree polynomial.

The horizontal asymptote will be the line y = b/a, where b and a are the coefficients of the highest degree terms in the numerator and denominator, respectively. In this case, b = 3 and a = 1, so the horizontal asymptote is y = 3.

The vertical asymptote of a function is the line x = a/b, where a and b are the coefficients of the highest degree terms in the numerator and denominator, respectively. In this case, a = 3 and b = -5, so the vertical asymptote is x = -3/5.

The area of the circle is 346.5 cm² while the area of the square is 272.25 cm². The figure that encloses more area is the circle.

If a wire of length 66cm is bent into the shape of a circle and square, then this length will be its circumference and perimeter, respectively.

C = 66cm = 2πr

r = 10.5 cm

P = 4s = 66cm

s = 16.5 cm

The area of the circle is given by the formula

A = πr²

A = π(10.5 cm)²

A = 346.5 cm²

So, the area of the circle is 346.5 cm².

The area of the square is given by the formula

A = s²

A = (16.5 cm)²

A = 272.25 cm²

So, the area of the square is 272.25 cm².

Therefore, the figure that encloses the greater area is the circle.

The particle is speeding up over the time interval (10/6, ∞).

The particle is speeding up when its acceleration is positive, which occurs when its second derivative is greater than 0. The second derivative of x (t) is 6t - 10, so the particle is speeding up when t > 10/6. Therefore, the particle is speeding up over the time interval (10/6, ∞).

To calculate this, we take the second derivative of x (t):

x''(t) = 6t - 10

We then set this equal to 0 and solve for t

6t - 10 = 0

t = 10/6

A population's per capita growth rate changes—typically declines—with rising population density due to density-dependent limiting constraints. One illustration is how individuals in a group compete for scarce food.

Independent of population density, several factors impact the per capita growth rate. Natural catastrophes like forest fires are examples.

Right question is in image.

So, when R is rotated along the line y = 4, the volume of the solid formed is roughly 12.57 cubic units. So, when R is rotated about the line y = 5, the volume of the solid formed is roughly 81.34 cubic units.

Every three-dimensional item requires some amount of space. The volume of this space is measured. Volume is defined as the space occupied by an item inside the confines of three-dimensional space. It is also known as the object's capacity.

Here,

The volume of the solid generated when R is rotated about the line y = 4 is given by the formula:

V = π * ∫[a,b] (x² - 4)² dx

where a and b are the x-coordinates of the points where the parabola y = x² intersects the line y = 4. To find these points, we set y = x² and y = 4 and solve for x:

x²= 4

x = ±2

So the points of intersection are (2, 4) and (-2, 4). The region R is the part of the parabola between these points, so a = -2 and b = 2.

Substituting these values into the formula for V, we have:

V = π * ∫[-2,2] (x² - 4)² dx

Evaluating the definite integral, we obtain:

V = π * [x⁵/5 - 4x³/3 + 16x] evaluated from -2 to 2

= π * (16/5 - 16/3 + 16 - (-16/5 + 16/3 - 16))

= π * (32/5)

= 12.57 ≈ 12.57 (rounded to 4 decimal places)

For the volume of the solid generated when R is rotated about the line y = 5, we can use the same formula:

V = π * ∫[a,b] (x² - 5)² dx

where a and b are the x-coordinates of the points where the parabola y = x² intersects the line y = 5. These can be found in the same way as before:

x² = 5

x = ±√5

So the points of intersection are (√5, 5) and (-√5, 5). The region R is the part of the parabola between these points, so a = -√5 and b = √5.

Substituting these values into the formula for V, we have:

V = π * ∫[-√5,√5] (x² - 5)² dx

Evaluating the definite integral, we obtain:

V = π * [x⁵/5 - 5x³/3 + 25x] evaluated from -√5 to √5

= π * (25/5 - 25/3 + 25√5/2 - (-25/5 + 25/3 - 25√5/2))

= π * (50/3 + 25√5)

= 50.97 + 25√5 ≈ 50.97 + 25 * 2.236 = 81.34 (rounded to 2 decimal places)

So the volume of the solid generated when R is rotated about the line y = 4 is approximately 12.57 cubic units. So the volume of the solid generated when R is rotated about the line y = 5 is approximately 81.34 cubic units.

30x2 is 60 so on the first box u put 2. Then u multiply again 30x2 which is 60 so u put the 60 on the box below the 76. U subtract

Next, you would subtract it which would turn out to be 16. Since 16 can't go in 30 equally, u would drop down the 2 in the 762 now you can do 30 into 162 which is 5 times bc 30x5 is 150 and doesn't go over so u put the 5 in the box next to the 2.

30x5 is 150, u put that in the box below 162. Then u subtract 162-150 which is 12. So you have a remainder of 12.

The scale factor is 1/5 inch per foot.

The scale factor of the drawing can be found by dividing the length of the rug in real life by the length of the rug in the drawing.

4 feet / (5 inches/12 inches/foot) = 4 * 12 / 5 = 9.6 inches

So the scale factor is 9.6 inches / 4 feet = 1/5 inch per foot.

The method used to find the scale factor is applicable to any drawing or model where the size of an object is known in both the real-life version and the drawing or model. As long as the ratio of the size of the object in the real-life version to the size of the object in the drawing or model is constant, the scale factor can be found using the same method.

The absolute maximum value of f is 1.

The function f(x) is defined as the natural logarithm of x (lnx) divided by x. This function is undefined when x is equal to 0, but for positive x values, the maximum value of f(x) is 1. To prove this, we need to take the derivative of f(x) and set it equal to 0. We can calculate the derivative of f(x) by using the quotient rule.

The quotient rule states that for two functions u(x) and v(x), the derivative of their quotient can be calculated by taking the derivative of u(x) times v(x) minus the derivative of v(x) times u(x), all divided by v(x)2. After taking the derivative of f(x) = lnx/x, we get f'(x) = (1/x) – (lnx/x2).

Now we set f'(x) = 0 and solve for x. This gives us x = 1, so when x = 1, we get the maximum value of f(x) = ln1/1 = 1. Therefore, the absolute maximum value of f is 1.
