i
Explanation:
An <em>explicit function</em> returns a value based only on the arguments given.
y = f(x)
__
A <em>recursive function</em> returns a value based on the arguments given and on other values of the function.
y = f(x, f(g(x))
$120
60 + 10 = 70
70 - 20 = 50
50 ÷ 2 = 25
70 + 50 = 120
A= P(1+r)^t, where P= initial value, r= interest rate in %, and t = number of years.
However, if there isa decrease in value, the formula becomes:
A= P(1-r)^t and in our case :
A = 30,000(1- 0.24)^t OR A = 30,000(0.76)^t
Answer:
The variation rate is 4.07 × 10⁻⁵ cm²/ºC
Step-by-step explanation:
The relationship of the change in length as a function of the temperature, which are given in this problem can be written by the expression for the area of a rectangle
a = L × W
Differentiating both sides,
= 
= W 
+ L 
The values they give us are
= 1.1 × 10⁻⁵ cm/ºC
= 8.9 × 10⁻⁶ cm/ºC
W = 1.6 cm
L= 2.6 cm
Substituting the values and calculating
= (1.6 × 1.1 × 10⁻⁵) + (2.6 × 8.9 × 10⁻⁶)
= (1.76 × 10⁻⁵) + (2.31 × 10⁻⁵)
= 4.07 × 10⁻⁵ cm²/ºC
The variation rate is 4.07 × 10⁻⁵ cm²/ºC
