Answer:

Use the given formulas and replace s with its value of 5 inches.

So the volume:

V = s³ = 5³ = 125 in³

Total surface area:

A = 6s² = 6*5² = 150 in²

Step-by-step explanation:

$volume = {a}^{3} = {5}^{3} = 5 \times 5 \times 5 = 125 {inch}^{3} \\ surface \: area = 6 {a}^{2} \\ = 6 \times {5}^{2} = 6 \times 5 \times 5 \\ = 150 {inch}^{2} \\ thank \: you$

Using a linear approximation, estimate f(2.1), given that f(2) = 5 and f'(x) = √3x-1.

algol [13]

Answer:

$f\left( {2.1} \right) \approx 5.22360$ .

Step-by-step explanation:

The linear approximation is given by the equation

${f\left( x \right) \approx L\left( x \right) }={ f\left( a \right) + f^\prime\left( a \right)\left( {x - a} \right).}$

Linear approximation is a good way to approximate values of $f(x)$ as long as you stay close to the point $x= a$ , but the farther you get from $x=a$ , the worse your approximation.
