Licemer1 [7]

Answer: the answer would be 20



Step-by-step explanation: The answer 20 is from 1400 divided by 70 making 20, if you take 1400 and turn it into 14 then 70 into 7 then divide 14 by 7 you get 2 now just add a zero to your answer.

Consider the piecewise function shown on the graph, which is composed of three different function types. ----- IMAGE ATTACHED BE
lesantik [10]

Answer:

Domain = (-\infty,-2) --- quadratic function

Domain = (-2,6) --- linear function

Domain = (6,\infty) --- square root function

Step-by-step explanation:

Given

The attached graph

Required

The domain of each function

Starting from the left; the first function is the quadratic function.

The curve of the quadratic function stops at -2 So, the domain is:

Domain = (-\infty,-2)

The straight line that starts at -2 and ends at 6 is a linear function.

So, the domain is:

Domain = (-2,6)

Lastly, the square root function begins at 6. So, the domain is:

Domain = (6,\infty)

An oil tank is being filled at a constant rate the depth of the oil is a function of the number of minutes has been filling, as
satela [25.4K]

We are given time in minutes.

According to given table, we are given times 0 minute, 10 minutes and 15 minutes.

And depths are given 3, 5 and 6.

Times represents x coordinates and depths represents y-coordinates.

First we need to find the depth of the tank in per unit time( in a minute).

In order to find the depth of the tank in per unit time, we need to find th slope between two coordinates.

Let us take first two coordinate made using table (0,3) (10,5)

We know, slope formula

m=\frac{y_2-y_1}{x_2-x_1}

Plugging values in slope formula, we get

m= \frac{5-3}{10-0}=\frac{2}{10}=\frac{1}{5}

We got slope m= 1/5=0.2.

We can say that depth of the tank is increasing by rate 0.2 per minute.

From the given table, we can see that for x=0, y value is 3.

Therefore, y-intercept is 3.

Let us write an equation of the line for given table in slope-intercept form y=mx+b.

Plugging values of m and b in slope-intercept form, we get

y= 0.2x+3.

We need to find the depth after 1/2 hours.

1 hour = 60 minutes,

Therefore, 1/2 hours = 60/2 = 30 minutes.

Plugging value of x=30 in above slope-intercept form of the equation, we get

y= 0.2(30)+3.

y= 3+6 = 9.

y=9

Therefore, the depth of the oil 1/2 hour after filling begins is 9 units.
