Answer: I'm pretty sure its a or the first one ^w^
Step-by-step explanation:
No it’s 2(x-6) this the right answer
Answer:
- dependent: number of cookies
- independent: number of hours
Step-by-step explanation:
If we write the description of the relationship between number of cookies (c) and time in hours (t) as ...
c = 40t
then c is the dependent variable and t is the independent variable.
_____
That's not the only way the relationship could be written. Which variable is which depends on how you define them and what you want to know. If you want to know the number of hours to bake "c" cookies, then "c" is the independent variable.
__
This sort of problem statement seems to assume that cookies are being produced continuously, not in batches. In order for any functional relation to properly express the scenario, the domain of the independent variable may need to be restricted to integer hours (or multiples of 40 cookies).
<span>B is the correct answer. Firstly, you have to work out the amount of interest earned per year by multiplying the sum invested ($16,000) by the interest rate (6.5%, or 0.065). Then multiply the result by eight to find out how much money Orlando would get when the CD reaches maturity if he doesn't withdraw any money. To calculate interest when money is withdrawn, multiply the annual interest by five, to work out how much interest Orlando earns in the first five years. Then work out the interest on the reduced investment ($16,000 - $3,500) in the same way and multiply by three to calculate the remaining three years' interest. Add the total interest for three years to the total interest to five years, which will tell you how much interest Orlando recieves when he makes the withdrawal. Finally, you can now take this away from the interest he would have made if he had not made a withdrawal, and this will tell you the difference. </span>

Given unit circle, so radius=1.
We calculate lengths of vertical segments, with the help of Pythagoras Theorem, based on a right triangle radiating from circle centre O, and hypotenuse from O to a point on the circumference.
AO=1 (given unit circle)
BB'=sqrt(1^2-0.25^2)=0.968246
CC'=sqrt(1^2-0.5^2)=0.866025
DD'=sqrt(1^2-0.75^2)=0.661438
EE'=0
Now we proceed to calculate the segments approximating the arc. Again, we use a right triangle in which the hypotenuse is the segment joining two points on the circumference. The height is the difference between the two vertical segments, and the base is 0.25 for all four segments.
AB=sqrt((AO-BB)^2+0.25^2)=0.252009BC=sqrt((BB-CC)^2+0.25^2)=0.270091CD=sqrt((CC-DD)^2+0.25^2)=0.323042DE=sqrt((DD-0)^2+0.25^2)=0.7071068
giving a total estimation of the arc length
approximation of arc=AB+BC+CD+DE=1.55225
