You have the expression:
![\frac{6a^3+(4b-c)^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6a%5E3%2B%284b-c%29%5E2%7D%7B2%7D)
And the given values are:
a=5
b=3
c=2
You substitute the given values in the equation:
![\frac{6(5^3)+(4(3)-2)^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6%285%5E3%29%2B%284%283%29-2%29%5E2%7D%7B2%7D)
Then you make the opperations:
![\frac{6(125)+(12-2)^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B6%28125%29%2B%2812-2%29%5E2%7D%7B2%7D)
![\frac{750+10^2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B750%2B10%5E2%7D%7B2%7D)
![\frac{750+100}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B750%2B100%7D%7B2%7D)
![\frac{850}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B850%7D%7B2%7D)
Finally, you get:
The answer is: C
The lower extreme is 9
The upper extreme is 22
The median is 15
The first quartile is 11
The third quartile is 19
[9] 10 [10 12] 13 [14 | 16] 17 [18 20] 21 [22]
Question:
A homeowner is building a flower bed in the backyard. He plans to put a layer of fertilizer over the entire flower bed.
Which expression represents the area in square feet that the homeowner will cover with fertilizer?
Answer:
![Area = 20w^3 + 7w^2 - 11w + 2](https://tex.z-dn.net/?f=Area%20%3D%2020w%5E3%20%2B%207w%5E2%20-%2011w%20%2B%202)
Step-by-step explanation:
Given
Required
Determine an expression for the area
Area is calculated as:
![Area = Length *Width](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2AWidth)
![Area = (4w^2 + 3w - 1) * (5w - 2)](https://tex.z-dn.net/?f=Area%20%3D%20%284w%5E2%20%2B%203w%20-%201%29%20%2A%20%285w%20-%202%29)
Expand
![Area = 20w^3 + 15w^2- 5w - 8w^2 - 6w + 2](https://tex.z-dn.net/?f=Area%20%3D%2020w%5E3%20%2B%2015w%5E2-%205w%20-%208w%5E2%20-%206w%20%2B%202)
Collect like terms
![Area = 20w^3 + 15w^2- 8w^2 - 5w - 6w + 2](https://tex.z-dn.net/?f=Area%20%3D%2020w%5E3%20%2B%2015w%5E2-%208w%5E2%20-%205w%20-%206w%20%2B%202)
![Area = 20w^3 + 7w^2 - 11w + 2](https://tex.z-dn.net/?f=Area%20%3D%2020w%5E3%20%2B%207w%5E2%20-%2011w%20%2B%202)
Answer:
Answer is option B

Y = 2x + 1
y = x²+1
reemplazando
2x+1 = x²+1
ordenando
0=x²-2x
donde
0 = x (x-2)
resolviendo
0=x v x-2=0
0 =x x= 2
si x=0 entonces y = 1 par (0,1)
si x=2 entonces y= 5 par (2,5)
