Where is the function increasing?<br> A)1 B)3&lt; X C)-infinity &lt; x &lt; 1<br> D)-infinity
eduard

Answer:

A) 1

Step-by-step explanation:

Given:

A graph of a function.

When we analyze the given graph, it is of a <em>parabola</em>.

To find:

The interval of values of x where the function is increasing.

Solution:

First of all, let us learn about the meaning of increasing and decreasing functions.

1. A function y=f(x) is known as increasing  in an interval a when

Value of y keeps on increasing when we move from the value of x from a to b.

2. A function y=f(x) is known as decreasing  in an interval a when

Value of y keeps on decreasing when we move from the value of x from a to b.

On analyzing the given graph , we can see that the graph is decreasing on the interval: -\infty

and is increasing on the interval: 1

When we choose from the options,

The correct answer is option A) 1

Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel. How long would i
Whitepunk [10]

Answer:

32 hours.

Step-by-step explanation:

Let x represent the time taken by Russell and Aaron to build the shed.

We have been given that Russell and Aaron can build a shed in 8 hours when working together. Aaron works three times as fast as Russel.

Russell's work rate would be \frac{1}{x}.

Since Aaron works three times as fast as Russel, so Aaron's work rate would be \frac{3}{x}.

Part of work done by in one hour would be \frac{1}{8}.

We can represent our given information in an equation as:

\frac{1}{x}+\frac{3}{x}=\frac{1}{8}

Let us solve for x.

\frac{1}{x}*8x+\frac{3}{x}*8x=\frac{1}{8}*8x

8+3*8=x

8+24=x

32=x

Therefore, it will take Russell 32 hours to build the shed working alone.
