To find the derivative, you must use the chain rule.
If u=x^3+2x:
dy/dx=(dy/du)(du/dx)
dy/du=d/du(e^u)=e^u=e^(x^3 + 2x)
du/dx =d/dx (x^3+2x) = 3x^2 + 2
So dy/dx=
e^(x^3+2x) * (3x^2+ 2)
X/100=135/45
x=300
The reasoning:
x represents the unknown present, which is over 100. 45 represents the whole, where as 135 is the part. Therefore, if you solve this proportion, x will equal 300%.
F=(5,8) e=(4,3) d=(x,y)
(5+x)/2=4 (8+y)/2=3
5+x=8 8+y=6
x=3 y=-2
d=(3,-2)
Answer:
(4,0)
Step-by-step explanation:
The zeros of the quadratic functions are where it crosses the x axis
It crosses at x=-2 and x=4
( -2,0) and (4,0)
Answer: The sample should contain 4870 cans of paint.
Step-by-step explanation:
According to the given information , we have
The prior estimate of proportion= 
Margin of error : E=0.01
Critical value for 98% confidence interval =
Formula to find the sample size :

i.e. 

Hence, the sample should contain 4870 cans of paint.
