Answer:
There would be 950 cm of thread left on the reel
Step-by-step explanation:
Here in this question, we are interested in knowing the amount of thread left on the reel.
To answer this question properly, we shall need to be consistent in using our units.
Thus, we need to convert the length of thread on the reel to cm.
Mathematically;
100cm = 1 m
let x cm = 15.25 m
x = 15.25 * 100 = 1525 m
Since 575 cm has been used for a project, the amount of thread in cm left on the reel will be;
1525 cm - 575 cm = 950 cm
Answer: 4, 2
Step-by-step explanation:
Answer:

Step-by-step explanation:
Since our equation is
and we want to solve for G, first we divide both sides by the product
, which gives:

So we are left with:

Now we multiply both sides by
, which gives:

Which gives us our final formula:

Answer:
y = 5cos(πx/4) +11
Step-by-step explanation:
The radius is 5 ft, so that will be the multiplier of the trig function.
The car starts at the top of the wheel, so the appropriate trig function is cosine, which is 1 (its maximum value) when its argument is zero.
The period is 8 seconds, so the argument of the cosine function will be 2π(x/8) = πx/4. This changes by 2π when x changes by 8.
The centerline of the wheel is the sum of the minimum and the radius, so is 6+5 = 11 ft. This is the offset of the scaled cosine function.
Putting that all together, you get
... y = 5cos(π/4x) + 11
_____
The answer selections don't seem to consistently identify the argument of the trig function properly. We assume that π/4(x) means (πx/4), where this product is the argument of the trig function.
