5 is a coefficient.  A coefficient is a number multiplied by a variable.


(2y+13) is a factor.  It can be multiplied by 8 to get an extended answer.


-1 is a constant.  A constant is a number that does not change.


Hope this helps!

Answer:

coefficient, factor and constant

Step-by-step explanation:

The given expression is:

5x-8(3y+13)-1

From the given expression , we get

In the first term, 5 is a coefficient of x (A coefficient is a number multiplied by a variable.).

In the second term, 3y+13 is the factor (It can be multiplied by 8 to get an extended answer)

In the third term, [tex-1[/tex] is a constant (A constant is a number that does not change)

Answer:

The pressure is changing at \frac{dP}{dt}=3.68

Step-by-step explanation:

Suppose we have two quantities, which are connected to each other and both changing with time. A related rate problem is a problem in which we know the rate of change of one of the quantities and want to find the rate of change of the other quantity.

We know that the volume is decreasing at the rate of \frac{dV}{dt}=-4 \:{\frac{cm^3}{min}} and we want to find at what rate is the pressure changing.

The equation that model this situation is

PV^{1.4}=k

Differentiate both sides with respect to time t.

\frac{d}{dt}(PV^{1.4})= \frac{d}{dt}k\\

The Product rule tells us how to differentiate expressions that are the product of two other, more basic, expressions:

\frac{d}{{dx}}\left( {f\left( x \right)g\left( x \right)} \right) = f\left( x \right)\frac{d}{{dx}}g\left( x \right) + \frac{d}{{dx}}f\left( x \right)g\left( x \right)

Apply this rule to our expression we get

V^{1.4}\cdot \frac{dP}{dt}+1.4\cdot P \cdot V^{0.4} \cdot \frac{dV}{dt}=0

Solve for \frac{dP}{dt}

V^{1.4}\cdot \frac{dP}{dt}=-1.4\cdot P \cdot V^{0.4} \cdot \frac{dV}{dt}\\\\\frac{dP}{dt}=\frac{-1.4\cdot P \cdot V^{0.4} \cdot \frac{dV}{dt}}{V^{1.4}} \\\\\frac{dP}{dt}=\frac{-1.4\cdot P \cdot \frac{dV}{dt}}{V}}

when P = 23 kg/cm2, V = 35 cm3, and \frac{dV}{dt}=-4 \:{\frac{cm^3}{min}} this becomes

\frac{dP}{dt}=\frac{-1.4\cdot P \cdot \frac{dV}{dt}}{V}}\\\\\frac{dP}{dt}=\frac{-1.4\cdot 23 \cdot -4}{35}}\\\\\frac{dP}{dt}=3.68

The pressure is changing at \frac{dP}{dt}=3.68.

zubka84 [21]

Answer:

x =  - 4 \\ x =  - 7

Step-by-step explanation:

x {}^{2}  + 28 =  - 11x \\ x {}^{2}  + 11x + 28 = 0 \\ x {}^{2}  + 7x + 4x + 28 = 0 \\ x(x + 7) + 4(x + 7) = 0 \\ (x + 4)(x + 7) = 0 \\  \\ x =  - 4 \:  \:  \:  \:  \:  \:   \\ \: x =  - 7
