Answer:
366.16
Step-by-step explanation:
area to paint = (10 x 6 x 2) + (10 x 2 x 2) + (6 x 2 x 2) = 184 m²
184 x 1.99 = 366.16
Answer
Find out the the value of the fourth term in a geometric sequence for which
![a_{1} = 10\ and\ r =0.5](https://tex.z-dn.net/?f=a_%7B1%7D%20%3D%2010%5C%20and%5C%20r%20%3D0.5)
To proof
The formula for the general term for each geometric sequence is
![a_{n} = a_{1} r^{n-1}](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%20a_%7B1%7D%20r%5E%7Bn-1%7D)
where
![a_{1} = first\ term,\ r = common\ ratio](https://tex.z-dn.net/?f=a_%7B1%7D%20%3D%20first%5C%20term%2C%5C%20r%20%3D%20common%5C%20ratio)
Put n= 4
![a_{4} = 10\times(0.5)^{4-1}](https://tex.z-dn.net/?f=a_%7B4%7D%20%3D%2010%5Ctimes%280.5%29%5E%7B4-1%7D)
![a_{4} = 10\times(0.5)^{3}](https://tex.z-dn.net/?f=a_%7B4%7D%20%3D%2010%5Ctimes%280.5%29%5E%7B3%7D)
![a_{4} = 10\times0.125](https://tex.z-dn.net/?f=a_%7B4%7D%20%3D%2010%5Ctimes0.125)
Solving
![a_{4} = 1.25](https://tex.z-dn.net/?f=a_%7B4%7D%20%3D%201.25)
The value of the fourth term in a geometric sequence is 1.25 .
Hence proved
Step-by-step explanation:
The third option: 5x(x^2+3)(4x-5)
because FOIL first, inner, outter, last
The two parentheses become (4x^3-5x^2+12x)
then 5x outside multiplys that whole parentheses. To get your correct expression
Answer:
Slope: -5/4 and y intercept: (0,-1)

The equation has the answer in it so ya :)
Hope dis helps :D
Answer:
Each point does NOT ALWAYS give the same amount of tickets.
11 point would most likely give 90 tickets.
Step-by-step explanation:
2 points give 18 tickets = 9 tickets per point
3 points give 27 tickets = 9 tickets per point
9 points give 72 tickets = 8 tickets per point
You can add the 2 point value with the 9 point values to find out many point it takes to get to 90 tickets.
18(2 tickets) + 72(9 tickets) = 90(11 tickets)
