4 Hours because he has already done two hours worth of work and he only needs six hours to complete it. The rest of the information is just a distraction
For this case we must simplify the following expression:

We know that:
By definition of power properties we have to:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
Rewriting the given expression we have:

Answer:
Option A
Answer:
r=12 as answer but as you will have reflective numbers (r12+2)(10x10)=3 in this sort of equation you will see that as they grew at a 88.3% rate 5/6 and 0.16 is a per month rate the coefficient value we can round down and call r12 = 6 for step 2 in the equation. As we can also find +0.88 which rounds to 1 and 0.33 the rate of change per month rounds to -1 and -100/12=8.3 if you are looking for the percentage. To find 6 we only need to 10/10 = 1. It is important you keep an equation simple for the growth as the change in measurement will always need a new percentage and we have a base number that can show such percentage as if it changed to 100% again at 12 inches we could reuse the equation =3-2=1 etc. or r12/100 =0.88 r=rise percentage and also be divided into 2 if we call r12 and r2 in same first equation to make r6.
Step-by-step explanation:
Answer:
y= -x-2
Step-by-step explanation:
y=ax+b
x= -2; y=0 => 0=-2a+b; b=2a
x= -1; y= -1 => -1=-a+b => b=a-1
2a=a-1=> a= -1; b= -2
=> y= -x-2
Answer: 6.48
Step-by-step explanation: hope it helps
