romanna [79]

Answer:

y = -3/2x + 3

Step-by-step explanation:

We can get 2 points from the graph

(0,3)

(2,0)

from (0,3) we know that the b in the equation is 3

now to calculate m or slope we use $\frac{y1-y2}{x1-x2}$

$\frac{0 - 3}{2-0}$ = -3/2

so we plug our m and b into y = mx + b and get

y = -3/2x + 3

Each side of a square is increasing at a rate of 6cm/s. At what rate is the area of the square increasing when the area of the s

diamong [38]

Area of a square = length²
A = x²
16 = x²; x = 4
dA/dx = 2x cm²/s
dx/dt = 6 cm/s
Using chain rule:
dA/dt = dA/dx * dx/dt
dA/dt = 2x * 6
dA/dt = 12x
At x = 4,
dA/dt = 12(4) = 48 cm²/s
