A survey of 1250 trees in a small wood showed that 32 percent were oak trees 26 percent were birch trees and the remainder were

timofeeve [1]

Answer: There were 525 pine trees.

Step-by-step explanation:

Given: Total trees = 1250

Percentage of oak trees = 32%

Percentage of birch trees = 26%

Since remaining trees are pine trees.

Percentage of pine trees = 100% - 32% - 26%

=42%

The number of pine trees = 42% of 1250

= 0.42 ×1250

= 525

Hence, there were 525 pine trees.

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.

If y varies directly as x, and y = 12 when x = 72, then what is the value of x when y = 3 ?

qwelly [4]

Answer:

x = 18

Step-by-step explanation:

difference between y = 12, x=72 is 6

so if y = 3 then multiply 3×6 = 18
