Tes, because acceleration is how fast it is speeding up, the average speed isn't being given because tornados don't last more than a few miles, and instantaneous speed gives current velocity in a certain direction at a certain time, therefore it would be anytime, including 3 minutes ago, meaning velocity, the current speed, is correct.

Find the derivative using the limit process of f (x) = - 10x
zubka84 [21]

Answer:

\frac{d}{dx} f(x) =-10

General Formulas and Concepts:

<u>Calculus</u>

  • Derivative Notation
  • Definition of a Derivative: \lim_{h \to 0} \frac{f(x+h)-f(x)}{h}

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -10x

<u>Step 2: Find Derivative</u>

  1. Substitute:                         \frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10(x + h)-(-10x)}{h}
  2. Distribute -10:                    \frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h-(-10x)}{h}
  3. Distribute -1:                      \frac{d}{dx} f(x)= \lim_{h \to 0} \frac{-10x -10h+10x}{h}
  4. Combine like terms:         \frac{d}{dx} f(x)=  \lim_{h \to 0} \frac{-10h}{h}
  5. Divide:                               \frac{d}{dx} f(x)=  \lim_{h \to 0} -10
  6. Evaluate:                           \frac{d}{dx} f(x)=-10

Write the following in slope intercept form:
BabaBlast [244]
To change it into slope intercept (y=mx+b) you just replace the inequality with an equality and isolate y

x<=2:
x=2=y-> y=2 or y=2+0x

2x-3y>=4:
2x-3y=4
2x-4=3y
(2/3)x-(4/3))=y
y=(2/3)x-(4/3)

x+y>0:
x+y=0
y=-x or y=-x+0
