Please write (x4 – 2) ÷ (x + 1) as <span>(x^4 – 2) ÷ (x + 1).
We can find the remainder using synth. div. as follows:
_________________
-1 / 1 0 0 0 -2
-1 1 -1 1
------------------------------
1 -1 1 -1 -1
The remainder is -1.</span>
The figure is not attached. So we will assume a rectangle that has sides of lengths 2 cm and width 3 cm and It is enlarged<span> with scale factor 3.
</span><span>The width of the original rectangle must be one-third of the enlarged rectangle.
</span>The lengths of the sides of the enlarged rectangle will be:
<span>3 × 2 cm = 6 cm (Length)
<span>3 × 3 cm = 9 cm (Width)</span></span>
For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: decrease rate
t: time in years.
Substituting values we have:
7 = A * (0.5) ^ ((1/20) * t)
For t = 45 years we have:
7 = A * (0.5) ^ ((1/20) * 45)
Clearing A:
A = 7 / ((0.5) ^ ((1/20) * 45))
A = 33.3
Answer:
the density of the substance when it was deposited 45 years ago was:
A = 33.3 milligrams per square centimeter
103 stays because it is the whole number and the next number after the decimal is below 5.
103 is your answer.
