Answer: 38/100
Step-by-step explanation: Beacuse the 8 is in the hundrenths place you put it as the number out of a 100
Answer: Second Option
Step-by-step explanation:
The formula for calculating the average rate of change between two values of x (
and 
) is:
and 
are the values of the function when 
and 
In this case
Observe that when 
, 
and when 
, 
Finally the average rate of change from 3 to 6 storms is:
The equation of a circle is written as (x – h)^2 + (y – k)^2 = r^2
h and k are the center point and r is the radius.
In the given equation h = -6 and k = 7 and r would be the square root of 81, which is 9.
Center (-6,7)
Radius = 9
We must know that the are of the triangle is given by definition by
A = (1/2) * (b) * (h)
where
b = base
h = height
Substituting the values
A = (1/2) * (x) * (1 + 6x)
A = (1/2) * (x + 6x ^ 2)
Since the area is 13 then
(1/2) * (x + 6x ^ 2) = 13
Clearing x we have
6x ^ 2 + x = 26
6x ^ 2 + x-26 = 0
(x-2) * (x + 13/6) = 0
As we look for the base of a triangle then x> 0
x = 2
answer
the base is x = 2
6x ^ 2 + x = 26
