Analyzing a Graph In Exercise, analyze and sketch the graph of the function. Lable any relative extrema, points of inflection, a

Anit [1.1K]

Answer:

Analyzed and Sketched.

Step-by-step explanation:

We are given $y=\frac{\ln\left(5x)}{x^2}$

To sketch the graph we need to find 2 components.

1) First derivative of y with respect to x to determine the interval where function increases and decreases.

2) Second derivative of y with respect to x to determine the interval where function is concave up and concave down.

$y'=\frac{1-2\ln\left(5x)}{x^3}=0$

$x = \sqrt e/5$ is absolute maximum

$y''=\frac{6\ln\left(5x)-5}{x^4}=0$

$x=e^{5/6}/5$ is the point concavity changes from down to up.

Here, x = 0 is vertical asymptote and y = 0 is horizontal asymptote.

The graph is given in the attachment.

Calculate the area of the following figure. All measurements are in centimetres. Give answer to correct two decimal places.

kykrilka [37]

Answer:

Step-by-step explanation:

The shape above is a composite shape having two different shapes like rectangle and semi- circle

Area of rectangle=Length × Breadth

Area of semi circle=1/2πr^2

To find the area of the rectangle naw

Length of the rectangle=6.6

Width of the rectangle=4

A=6.6×4

A=26cm^2

Area of semi-circle=1/2

Diameter of the shape =4cm

Radius=2cm

A=1/2×3.14×2cm x2cm

A=6.28cm^2

Area of the shape=26+6.28cm^2

Area=32.28 to 2 dp
