Answer:
linear functions change a constant rate. i.e. the slope of the graph is constant.
d/dx (mx+b) = m
quadratic functions change at a linear rate, slower than the function itself.
The slope of the tangent to the graph is proportional to the x coordinate.
d/dx (ax^2) = 2ax
Slope of tangent to ax^2 at point (x,ax^2) is 2ax.
Exponential functions change at the same rate as the function itself. The slope of the tangent to the graph is proportional to the y coordinate.
The slope of tangent at point (x,exp(x)) is exp(x).
Definition of exp(x) is just exp(0) = 1 and d/dx exp(x) = exp(x).
d/dx exp(ax) = a exp(ax) is not part of the definition, but follows from from the chain rule
Step-by-step explanation:
Lets first convert the tons to pounds.
1 ton = 2000 pounds
18 × 2000 = <span>36000
</span><span>18 tons = 36000 pounds
</span>
36000 + 42 = <span>36042
</span>36042 ÷ 3 = <span>12014
</span>
18 tons 42 pounds divided by 3 is <span>12014. </span>
Answer:
Area_circle = pi*13^2 = ~530.29
Area_sector = pi*13^2* 315/360 = ~464.56
Answer:
143 Minutes or 2 hours and 23 Minutes
Step-by-step explanation:
You have to find the rate at which she is typing and spell checking the pages
Ex//
26 minutes= 14 pages ----- simpllify to 13 Minutes= 7 pages
----you want to know how long it takes to do 77 pages---
77 can be found by multiplying 7 x11 so do the same with 23 (23x11)
** don't forget the unit!**
