2/3 A = 16
The multiplicative inverse is also known as the reciprocal. To solve for the value of A, multiplicative inverse is required.
<span>The multiplicative inverse of 2/3 is 3/2. When you divide a number by a fraction, you first get the reciprocal of the fraction. Then, you multiply the number by the reciprocal of the fraction. </span>
2/3 A = 16
A = 16 / 2/3
A = 16 * 3/2
A = 48 / 2
A = 24
To check:
2/3 A = 16
2/3 (24) = 16
48 / 3 = 16
16 = 16
For this, we need to know the length of the base at the time of interest. It will be
... A = (1/2)bh
... b = (2A)/h = 2(81 cm²)/(10.5 cm) = 108/7 cm
Differentiate the formula for area and plug in the given numbers.
... A = (1/2)bh
... A' = (1/2)(b'h +bh')
... 3.5 cm²/min = (1/2)(b'·(10.5 cm) + (108/7 cm)·(2.5 cm/min))
... 7 cm²/min = 10.5b' cm + 38 4/7 cm²/min . . . . simplify a bit
... -31 3/7 cm²/min = 10.5b' cm . . . . . . . . . . . . . . . subtract 38 4/7 cm²/min
... (-220/7 cm²/min)/(10.5 cm) = b' ≈ -3.0068 cm/min
The base is changing at about -3 cm/min.
