You need to look at the x values when you calculate that.

There is a line which goes from -2 to 0. Another line at 0 to 4 and the last line is 7 to infinity.

You can combine the first two and get B) (-2, 4] and [7, infinity)

The domain of the graph is $\boxed{\left({ - 2,4}\right]{\text{ and }}\left[ {7,\infty }\right)}$ . Option (b) is correct.

Further explanation:

Domain is a set of all the possible values of the function. The values at which the function is defined is known as domain.

Range is a set of values that the function takes.

The output values of the function are known as range and the input values on which function is defined is known as the domain of the function.

Explanation:

The x coordinates are the domain of the function and the y coordinates are the range of the function.

The included value of the function is denoted by the solid circle and in the interval it is represented by close interval “ $\left[{}\right]$ ”.

The values that are not included in the function are denoted by the hollow circle and in the interval is is denoted by “ $\left({}\right)$ ”.

From the graph it has been observed the -2 is not included in the domain, 4 is included in the domain as well 7 is also included in the domain.

The domain of the graph is $\boxed{\left({ - 2,4}\right]{\text{ and }}\left[{7,\infty }\right)}$ .

Option (a) is not correct as the domain of the graph is $\boxed{\left({ - 2,4}\right]{\text{ and }}\left[{7,\infty }\right)}$ .

Option (b) is correct.

Option (c) is not correct.

Option (d) is not correct.

Water flows into a tank according to the rate F of t equals the quotient of 6 plus t and the quantity 1 plus t, and at the same

diamong [38]

Answer:

Step-by-step explanation:

The complete question is

Water flows into a tank according to the rate F(t)= (t+6)/(1+t), and at the same time empties out at the rate E(t)= (ln(t+2))/(t+1), with both F(t) and E(t) measured in gallons per minute. How much water, to the nearest galllon, is in the tank at time t=10 minutes.

Let C(t) be the amount of water in the tank at time t. We now that the rate of change of the tank is given by

$\frac{dC}{dt}=[\tex]rate at which water flows in- rate at which water flows out. Then [tex]\frac{dC}{dt}=\frac{t+6}{t+1}-\frac{\ln(t+2)}{(t+1)}[\tex]so, the desired expression is obtained by integrating with respect to t. This leads us to [tex]C(t) = \int \frac{t+1}{t+1}+ \frac{5}{t+1} - \frac{\ln(t+2)}{(t+1)} dt=t+ 5 \ln (|t+1|)-\int \frac{\ln(t+2)}{(t+1)} dt +C$

Unfortunately, the integral $\int \frac{\ln(t+2)}{(t+1)} dt$ cannot be expressed using fundamental functions. So, the problem cannot have an specific function (if you are willing to know the complete answer, the integral of this function uses the polylogarithm function with n=2).

Since you want the exact amount of water at time, you need to give C a value, that is, you need to know an initial condition for the problem. This means, you need to know the amount of water in the tank at time 0

How many 0.6 liter glasses can help you fill up with a 4.5 liter pitcher? need work also

Kisachek [45]

You can fill up 7.5 liter glasses with a 4.5 liter pitcher. This is because 4.5 ÷ .6 = 7.5. Just use long division! :)
