60:£3.Give the answer in lowest terms

AysviL [449]

Answer:

20:£1

Step-by-step explanation:

To simplify a ratio is like like simplifying a fraction

Take 4/8 as an example. Find a number you can divide both numbers with. In this case, it's 4. 4 divided by 4= 1, and 8 divided by 4= 2. So, the simplified version of 4/8 is 1/2. Similarly, with the ration 60:£3, you find the number you can divided both numbers with. In this case, it is 3. 3 divided by 3= 1, and 60 divided by 3= 20.

Final Answer: 20:£1

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

dlinn [17]

Answer:

Analyzed and Sketched.

Step-by-step explanation:

We are given $y = \ln(2x) - 2x^2$ .

We need to find the following to sketch the graph.

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.

$y' = \frac{1}{x} - 4 x=0$

The roots are x = -1/2 and x = 1/2 but negative one cannot be possible due to logarithmic function.

x = 1/2 is absolute maximum.

$y''=-4 - \frac{1}{x^2}$

So, concavity is always down.

Here, x = 0 is vertical asymptote.

I attached the picture of sketched graph.

A robot is expected to filter pollution out of at least 350 liters of air and water. It filters air at the rate of 50 liters per

s2008m [1.1K]

Answer:

$20W+50A\geq 350$

Step-by-step explanation:

we are given that A robot is expected to filter pollution out of at least 350 liters of air and water.

Also It filters air at the rate of 50 liters per minute, and it filters water at the rate of 20 liters per minute.

The inequality for number of minutes the robot should filter air (A) and water (W) to meet this expectations can be writte as follows:

$20W+50A\geq 350$

Hence the required inequality has been formulated.
