y = x^2 -4x
x = -1
y = (-1)^2 - 4×-1=1+4 = 5
x= 0
y = (0)^2 - 4×0 = 0
x = 1
y = 1^2 -4×1 = 1-4 = -3
x = 2
y = 2^2 -4×2 = 4-8 = -4
x=3
y = 3^2 - 4×3 = 9-12 = -3
x = 4
y = 4^2 - 4×4 = 16 - 16 = 0
now 2nd equation
y = 2x^2 + x
x = -2
y = 2 (-2)^2 + (-2)= 8-2 = 6
x = -1
y = 2 (-1)^2+(-1)= 2-1 = 1
x = 0
y = 2(0)^2 +0 = 0
x = 1
y = 2 (1)^2 + 1 = 3
x = 2
y = 2(2)^2+2= 8 + 2 = 10
Answer:
Step-by-step explanation
The length of the left sloping line
= √ (5^2 + 7^2) = √74.
The right sloping line
= √(5^2 + 5^2) = √50.
So the perimeter:
= √74 + √50 + 2 + 2 * 4 + 14
= 39.67 to nearest hundreth.
Area = 1/2 * 5 * 7 + 2*5 + 1/2 * 5 * 5 + 4*14
= 96.
0.7+0.75=1.45 (this total is for both steaks)
8.68÷1.45=0.60 (the total he paid for both steaks divide by the total weight of the steaks.)
so, the answer is 60cents per lb. on the steaks.

Step-by-step explanation:
The recursive function tells you the first term is 1. That is the meaning of ...
![a_1=1](https://tex.z-dn.net/?f=a_1%3D1)
It also tells you that to find the next term, you multiply this term by 1/2:
![a_2=\dfrac{1}{2}a_1=\dfrac{1}{2}\cdot 1=\dfrac{1}{2}](https://tex.z-dn.net/?f=a_2%3D%5Cdfrac%7B1%7D%7B2%7Da_1%3D%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%201%3D%5Cdfrac%7B1%7D%7B2%7D)
And, to find the next term, you multiply this term by 1/2:
![a_3=\dfrac{1}{2}a_2=\dfrac{1}{2}\cdot\dfrac{1}{2}=\dfrac{1}{4}](https://tex.z-dn.net/?f=a_3%3D%5Cdfrac%7B1%7D%7B2%7Da_2%3D%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%5Cdfrac%7B1%7D%7B2%7D%3D%5Cdfrac%7B1%7D%7B4%7D)
Then the first three terms are ...
1, 1/2, 1/4
Answer:
Step-by-step explanation:
Answer:(A)= (-x^11)/(y^7)
(B)= (1/12xy^5)
Step-by-step explanation:
(A) (3x^3y^-2)(-2x^-3y^2)^-5/(6x^7y^-5)
[(3x^3y^-2)(-2x^15y^-10)]/(6x^7y^-5)
(6x^18y^5)/(-6x^7y^12)
(-6x^11)/(6y^7)
(-x^11)/(y^7)
(B) [(12x^-3y^5)/(x^-4)]^-1
(1/12xy^5)
