Answer:
ummmm..... let's see..
Step-by-step explanation:
using "Almighty formula"
{Y = –x +/– √b^2 – 4ac / 2a}
so we name all the values behind the coefficients which are; –1^2, 8 and 11
so let's assign a,b,c to these values:
a =–1, b =8, c = 11
all you just do now is to add these values to the formula
you should be having Y =1 +/– √8^2 – 4×–1×11
———————————
2×–1
Y =1 +108
———— or Y = 1–108
–2 –––––
–2
now add and divide to get Y.
(your answer will be two)
Answer:
![a(n)=8.3^{n-1}](https://tex.z-dn.net/?f=a%28n%29%3D8.3%5E%7Bn-1%7D)
Choice D is correct
Step-by-step explanation:
The sequence representing the number of raccoons;
8, 24, 72
is simply but a geometric sequence with first term 8 and common ratio 3.
The formula for the n-th term of a geometric sequence with first term x and common ration r is;
![a(n)=xr^{n-1}](https://tex.z-dn.net/?f=a%28n%29%3Dxr%5E%7Bn-1%7D)
In the given case, x = 8 and r = 3
We substitute these values in the above formula;
![a(n)=8.3^{n-1}](https://tex.z-dn.net/?f=a%28n%29%3D8.3%5E%7Bn-1%7D)

Total package of the agency = 2cities×1 month × 6 airlines=12 packages.
Answer:
Step-by-step explanation:
14) since this is a square each side is going to be the same length; all sides will be 9 ft long
x + 2 = 9 9 - 2 = 7 X = 7
to get the area of the square you must find the length of one side.... we know it is 9.... then we multiply the length by itself.... in this case 9 x 9
9 x 9 = 81 ft
15) formula to find the area of a right triangle is: A = ab/2
In this case a = 8cm and b = (x + 1) cm
In order to meet the requirement of ≤ 44 ab must = ≤ 88
since we multiply ab then x has to be 10 or less since 10+1=11
and 11 x8 = 88 and 88 divided by 2 = 44
