The table shows the temperature of ocean water in degrees Celsius at different depths in meters: Depth (meters) 0 500 1,000 1,50
NARA [144]

You can use the fact that the corresponding values from both the columns are taken into ordered pair (x,y) form to plot them on the 2d graphs (for 2 data values' set)

The scatter plot best representing the data in the table is given by

Option D:   Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

<h3>How are ordered pairs formed for plotting 2d data?</h3>

There are two axis in the graph. Horizontal axis and vertical axis. The independent variable is plotted on horizontal axis and dependent variable's values are plotted on vertical axis.

Since the temperature is measured on each value of depth, thus, depth is independent and temperature is depending on the depth.

The data points are ordered as

(independent variables' value, dependent variables' value at that value of independent variable)

Thus, for the given table, we will have:

(0, 23.5), (500, 12), ... points.(it is denoting like what was the value of second variable when first variable was this. Like when depth was 0, temperature was 23.5 degrees Celsius, and so on).

Thus,

The scatter plot best representing the data in the table is given by

Option D:   Plots ordered pairs 0, 23. 5 and 500, 12 and 1000, 6 and 1500, 4. 2 and 2000, 4 and 2500, 3. 8 and 3000, 3 and 3500, 2. 8 and 4000, 2.

The width of a rectangle is increasing at a rate of 2 cm/sec, while the length increases at 3 cm/sec. At what rate is the area i
lorasvet [3.4K]

Answer:

The area of the rectangle is increasing at a rate of  22\ cm^2/s.

Step-by-step explanation:

Given : The width of a rectangle is increasing at a rate of 2 cm/ sec. While the length increases at 3 cm/sec.

To find : At what rate is the area increasing when w = 4 cm and I = 5 cm?

Solution :

The area of the rectangle with length 'l' and width 'w' is given by  A=l w

Derivative w.r.t  't',

\frac{dA}{dt}=w\frac{dl}{dt}+l\frac{dw}{dt}

Now, we have given

\frac{dl}{dt}=3\ cm/s

l=5\ cm

\frac{dw}{dt}=2\ cm/s

w=4\ cm

Substitute all the values,

\frac{dA}{dt}=(4)(3)+(5)(2)

\frac{dA}{dt}=12+10

\frac{dA}{dt}=22\ cm^2/s

Therefore, the area of the rectangle is increasing at a rate of  22\ cm^2/s.

Find the annual infiltration rate for the nearest 10th of a percent of a gallon of milk that increases the value from $1.51 to $
Leno4ka [110]

Answer:

7.429 cents

Step-by-step explanation:

Given that:

Price change = $1.51 to $2.03

Period of time = 7 years

Therefore, the annual inflation rate :

Difference in price / number of years

($2.03 - $1.51) / 7

$0.52 / 7

= 0.0742857 per year

= 0.0742857 * 100 (about 7.429 cents per year)

Hitman42 [59]

Answer:

Gross pay for the week = $603.85

Step-by-step explanation:

Monday pay = (5.4 x 8) + (2.7 x 1) = $45.9

Tuesday pay = 5.4 x 8 = $43.2

Wednesday pay = (5.4 x 8) + (2.7 x 3) = $51.3

Thursday pay = (5.4 x 8) + (2.7 x 1) = $45.9

Friday pay = (5.4 x 8) + (2.7 x 2) = $48.6

Saturday pay = 5.4 x 8 = $43.2

Commission on first $3000 = 0.04 x 3000 = $120

Commission on sales above $3000 = 0.05 x 4115 = $205.75

Gross pay for the week = 45.9+43.2+51.3+45.9+48.6+43.2+120+205.75 = $603.85
