You answered it correctly :)
Step-by-step explanation:
Remember
(a-b)(a+b)=a²-b²
we can rewrite what we were given into
definitely rational
I would make the equation 800x=120, x representing the decimal form of the unknown percentage
800x=120
x=0.15 (divide both sides by 800)
Then move the decimal point twice to the right to get 15%
Hope this helps
Answer:
108.7 ft
Step-by-step explanation:
Put 30 where x is and do the arithmetic.
y = -3.29·30 -10 = -98.7 -10 = -108.7
The trend line predicts the depth to be 108.7 ft after 30 minutes.

<em>Comment on this problem</em>
Real-world considerations in scuba diving may cause the diver to level off or head toward the surface before 30 minutes elapse. The trend line does not model these effects.
The answer would be 5314 plus 42342 plus 2521. And multiply by 6. The answer you'll be 301,062
