Definition of a Derivative: \displaystyle f'(x) =  \lim_{h \to 0} \frac{f(x + h) - f(x)}{h}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle  \lim_{h \to 0} \frac{f(3 + h) - f(3)}{h}<em />

<em />\displaystyle f(x) = x^3<em />

<em />

<u>Step 2: Solve</u>

  1. Substitute in function value:                                                                            \displaystyle  \lim_{h \to 0} \frac{(3 + h)^3 - 3^3}{h}
  2. Evaluate exponents:                                                                                         \displaystyle  \lim_{h \to 0} \frac{(3 + h)^3 - 27}{h}
  3. Expand:                                                                                                             \displaystyle  \lim_{h \to 0} \frac{h^3 + 9h^2 + 27h + 27 - 27}{h}
  4. [Subtraction] Combine like terms:                                                                   \displaystyle  \lim_{h \to 0} \frac{h^3 + 9h^2 + 27h}{h}
  5. Factor:                                                                                                                \displaystyle  \lim_{h \to 0} \frac{h(h^2 + 9h + 27)}{h}
  6. Simplify:                                                                                                             \displaystyle  \lim_{h \to 0} h^2 + 9h + 27
  7. Evaluate limit:                                                                                                    \displaystyle 0^2 + 9(0) + 27
  8. Evaluate exponents:                                                                                         \displaystyle 9(0) + 27
  9. Multiply:                                                                                                             \displaystyle 27

Find the value of x please
Natasha_Volkova [10]

Answer:

x=70

Step-by-step explanation:

The value of x is 70 because this triangle is isosceles, meaning that there are two congruent sides and two congruent angles (which are the base angles). x is one of the base angles, 70º is the other base angle's measurement, so x=70.
