Let the side length of the square be x, then A = x^2
but diagonal (z) = sqrt(2x^2)
z^2 = 2x^2
x^2 = 1/2 z^2
Thus, A = 1/2 z^2
dA/dz = 1/2 (2z) = z
The rate of change is z.
When z = 4, the rate is 4.
Answer: 12.1
Look at the hundredth place for rounding to tens and since it is less than 5 you drop the following numbers and keep the 1
:)<span />
Answer:
m = 10
Step-by-step explanation:
Find 'n' first..... then pythag theorem for 'm'....
n is to 5 as 15 is to n
n/5 = 15/n
n^2 = 75 n = sqrt (75)
Then m^2 = n^2 + 5^2
m^2 = 75 + 25 s-o-o-o-o: m = 10
*12 + 1.5x = 16 + 0.50x*
That's the answer, since I'm late.
This is correct because when setting up this sentence as an equation, you need to look at the numbers and how they're used. There are independents and dependents.
indep.:
12,16
dep.:
1.50,0.50
Furthermore, there are 1 of each on both sides of the equation, match them from the equation by name and you get the answer.

i think 16
