Area of a Rectangle: A = lw

Exponential Property: $w^n \cdot w^m = w^{n + m}$

Calculus

Derivatives

Differentiating with respect to time

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Explanation:

Step 1: Define

Area is A = lw

2w = l

w = 300 m

$\frac{dw}{dt} = 24 \ m/year$

Step 2: Rewrite Equation

Substitute in l: A = (2w)w
Multiply: A = 2w²

Step 3: Differentiate

Differentiate the new area formula with respect to time.

Differentiate [Basic Power Rule]: $\frac{dA}{dt} = 2 \cdot 2w^{2-1}\frac{dw}{dt}$
Simplify: $\frac{dA}{dt} = 4w\frac{dw}{dt}$

Step 4: Find Rate

Use defined variables

Substitute: $\frac{dA}{dt} = 4(300 \ m)(24 \ m/year)$
Multiply: $\frac{dA}{dt} = (1200 \ m)(24 \ m/year)$
Multiply: $\frac{dA}{dt} = 28800 \ m^2/year$

Which process changes substances into new substances with new properties?

Y_Kistochka [10]

Answer:

The answer to your question is: Chemical change

Explanation:

Chemical Change is a change where substances change their properties because new substances are obtain. This is the right answer.

Compressibility is a property in which a substance is compressed but it continous being the being so this answer is wrong.

Malleability is a property in whcih substances are flattened into thin sheets but they don't change their properties. This answer is wrong.

Physical Change is a change in which a substance changes its physical state but the properties are the same than the original substance, this answer is wrong.
