Y = xe^x
dy/dx(e^x x)=>use the product rule, d/dx(u v) = v*(du)/(dx)+u*(dv)/(dx), where u = e^x and v = x:
= e^x (d/dx(x))+x (d/dx(e^x))
y' = e^x x+ e^x
y'(0) = 1 => slope of the tangent
slope of the normal = -1
y - 0 = -1(x - 0)
y = -x => normal at origin
30% just means 30/100 which can be simplified to 3/10. In order to find the number of hits you just need to multiple .3 by the total attempts, being 240, which comes out as 76.
Answer:
Average rate of change 
Step-by-step explanation:
Given function is
and we need to find average rate of change of the function from
.
Average rate of change 
So,

Average rate of change

Hence, average rate of change of the function
over the intervel
is
.
Answer:
The original number of oranges purchased is 260
Step-by-step explanation:
Let the original number of oranges purchased be x
We are given that The number of oranges a grocery store bought this year was 15% more than the number of oranges bought last year.
So, Oranges bought this year = 
We are given that This year the store bought 299 oranges.
So, 

x=260
Hence the original number of oranges purchased is 260
range is output or y
(x,y)
the range is the 2nd number
when it repeats, don't list again
range=3,5.9,8.3
