Each side of a square is increasing at a rate of 2 cm/s. at what rate is the area of the square increasing when the area of the

faltersainse [42]

Let x(t) = the length of a side of the square (cm) at time t (s).
The rate of change of x is given as
$\frac{dx}{dt} =2 \, \frac{cm}{s}$

The area (cm²) at time t is
A = x²

The rate of change of the area with respect to time is
$\frac{dA}{dt} = \frac{dA}{dx} \frac{dx}{dt} =2 \frac{dA}{dx} =2(2x)=4x \, \frac{cm^{2}}{s}$

When A = 9 cm², then x = √9 = 3cm. Hence obtain
$\frac{dA}{dt} = 4(3) = 12 \, \frac{cm^{2}}{s}$

Answer: 12 cm²/s

How many pounds of coffee Worth

Firdavs [7]

Answer:

the number of pounds that should be mixed is 30 pounds

Step-by-step explanation:

The computation of the number of pounds that must be mixed is shown below:

Let us assume the number of pounds be x

Now the equation is

(x) (1) + (15) (1.60) = (x + 15) (1.20)

x + 24 = 1.20x + 18

24 - 18 = 1.20x - x

6 = 0.20x

x = 30 pounds

Hence, the number of pounds that should be mixed is 30 pounds
