She has 84 pictures and 12 others were bad for a total of 84+12 = 96 pictures were taken.
Divide the total pictures taken by 24 per roll:
96 / 24 = 4
She used 4 rolls of film.
Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
a = pi * r ^ 2
d = 2 * r
r = d / 2
r = 96/2
r = 48
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
r = 88/2
r = 44
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
The graph touches the x-axis at x = 4 and is turning away. This means that the graph has even multiplicity at x = 4.
So, the roots of the polynomial are x = 4 and x = 4 and the factors of the polynomial are x - 4 and x - 4. The polynomial can be expressed as the product of its factors. So the given polynomial can be expressed as (x - 4)(x - 4).
