Answer:

143 acres.

Step-by-step explanation:

To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.

To find a percent of a number, multiply the percent by the number.

0.2% is equal to 0.002.

73,000 x 0.002 = 143

So, 143 acres of the forest is old-growth trees.

Which statement describes the function y=ax^n when a=1 and n is odd?
julsineya [31]
ANSWER

B. The graph is symmetric about the origin

EXPLANATION.

The given function is

y = a {x}^{n}

When a=1,

y = {x}^{n}

Let,

f(x)= {x}^{n}

f(-x)= {( - x)}^{n}

Since n is odd,

f(-x)=-{( x)}^{n}

\Rightarrow f(-x)=-f(x)

This implies that, the function

y={x}^{n}

is symmetric with respect to origin.

The correct answer is B
