Use the definition f ′(x) = h0f(x + h) - f(x)h to find the derivative. f(x)=x+2

NNADVOKAT [17]

Answer:

f'(x) = 1

General Formulas and Concepts:

Calculus

Limit Properties: $\lim_{n \to a} c = c$
Definition of a Derivative: $f'(x)= \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}$

Step-by-step explanation:

Step 1: Define

f(x) = x + 2

Step 2: Find derivative

Substitute: $f'(x)= \lim_{h \to 0} \frac{((x + h) + 2)-(x+2)}{h}$
Distribute: $f'(x)= \lim_{h \to 0} \frac{x + h + 2-x-2}{h}$
Combine like terms: $f'(x)= \lim_{h \to 0} \frac{h}{h}$
Divide: $f'(x)= \lim_{h \to 0} 1$
Evaluate: $f'(x)= 1$

Its not. because 16 / .75 (which is 3/4) = 21.33--

3 * 16 = 48 / 4 = 12

I hope this helps :)

orest fire covers 2008 acres at time t equals 0. The fire is growing at a rate of 8 StartRoot t EndRoot acres per hour, where t

AveGali [126]

Answer: There are 2635 acres covered 24 hours later.

Step-by-step explanation:

Since we have given that

At time t = 0, number of acres forest fire covers = 2008 acres

We first consider the equation:

$A=\int\limits^t_0 {8\sqrt{t}} \, dt\\\\A=8\dfrac{t^{\frac{3}{2}}}{\frac{3}{2}}+C\\\\A=\dfrac{16}{3}t^{\frac{3}{2}}+C$

At t=0, A= 2008

So, it becomes,

$2008=C$

So, now it becomes,

$A=\dfrac{16}{3}t^{\frac{3}{2}}+2008\\\\At\ t=24,\\\\A=\dfrac{16}{3}(24)^{\frac{3}{2}}+2008\\\\A=2635.06$

Hence, there are 2635 acres covered 24 hours later.
