The area of a circle is:
A=pr^2
You are told r=32 so
A=p32^2
A=1024p u^2
It’s the second one for number #5 . hope this helps
the assumption being that the first machine is the one on the left-hand-side and the second is the one on the right-hand-side.
the input goes to the 1st machine and the output of that goes to the 2nd machine.
a)
if she uses and input of 6 on the 2nd one, the result will be 6² - 6 = 30, if we feed that to the 1st one the result will be √( 30 - 5) = √25 = 5, so, simply having the machines swap places will work to get a final output of 5.
b)
clearly we can never get an output of -5 from a square root, however we can from the quadratic one, the 2nd machine/equation.
let's check something, we need a -5 on the 2nd, so
so if we use a "1" as the output on the first machine, we should be able to find out what input we need, let's do that.
so if we use an input of 6 on the first machine, we should be able to get a -5 as final output from the 2nd machine.
If you would like to know how many times does 50 go into 85, you can calculate this using the following steps:
85 / 50 = 17 / 10 = 1.7
The correct result would be 1.7.
C
Trinomial means three parts
A and C or trinomial's but the degree on a is at three and the degree of C is a one
