Answer:
Last choice. d.
Step-by-step explanation:
We are given the first term and the sixth term.
The first term is
.
The sixth them is
.
Let's solve for the common ratio, r.
![-9r^5=-9216](https://tex.z-dn.net/?f=-9r%5E5%3D-9216)
Divide both sides by -9:
![r^5=1024](https://tex.z-dn.net/?f=r%5E5%3D1024)
Take the fifth root of both sides:
![r=1024^{\frac{1}{5}}](https://tex.z-dn.net/?f=r%3D1024%5E%7B%5Cfrac%7B1%7D%7B5%7D%7D)
![r=4](https://tex.z-dn.net/?f=r%3D4)
So the common ratio is 4.
![a_1=-9](https://tex.z-dn.net/?f=a_1%3D-9)
![a_2=-9(4)=-36](https://tex.z-dn.net/?f=a_2%3D-9%284%29%3D-36)
![a_3=-9(4)^2=-144](https://tex.z-dn.net/?f=a_3%3D-9%284%29%5E2%3D-144)
![a_4=-9(4)^3=-576](https://tex.z-dn.net/?f=a_4%3D-9%284%29%5E3%3D-576)
![a_5=-9(4)^4=-2304](https://tex.z-dn.net/?f=a_5%3D-9%284%29%5E4%3D-2304)
![a_6=-9(4)^5=-9216](https://tex.z-dn.net/?f=a_6%3D-9%284%29%5E5%3D-9216)
Answer/explanation :
Step-by-step
subtract 15-8 you have 7 then take
10- ur answer is 7
10-7= 3
Answer:
Step-by-step explanation:
Slope m = (-8-2)/(1+1)=-10/2 = -5
Perpendicular slope-1/m = -1/-5 = 1/5
Equation of a line with perpendicular slope is
y-y1=(-1/m)(x-x1)
y - 2 = (1/5)(x+1)
y =2 +(1/5)(x+1)
4.44+77079.9704=77084.4104
The answer to this problem is 2/5
