Well 1/40 is 0.025 so that should be the write fraction to use
9900 because you divide 99000 by 10
Note: a² - b² = (a-b)(a+b)
9x² - 16y² = (3x)² - (4y)² = (3x - 4y)(3x + 4y)
Answer:
Increasing if f' >0 and decreasing if f'<0
Step-by-step explanation:
Difference quotient got by getting
will be greater than 0 if function is increasing otherwise negative
Here h is a small positive value.
In other words, we find that whenever first derivative of a function f(x) is positive the function is increasing.
Here given that for x1, x2 where x1<x2, we have
if f(x1) <f(x2) then the function is decreasing.
Or if x1<x2 and if f(x1) >f(x2) for all x1, and x2 in I the open interval we say f(x) is decreasing in I.
Answer:
The area of the triangle with the given measurements is 200 in²
Step-by-step explanation:
For this problem, we will need to know the formula for finding the area of a triangle.
<em>A = 1/2(bh)</em>
Now, let's plug in these numbers so we can find the area.
A = 1/2(bh)
A = 1/2(16*25)
A = 1/2(400)
A = 200 in.²
