Answer:
113.1 m^2
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
first term a= 2
last term tn= 32
common ratio r= -2
number of terms
= tn=ar^n-1
32 = 2*(-2)^n-1
divide both sides by 2
32/2 = 2*(-2)^n-1/2
16 = (-2)^n-1
Then...use 16 in the power of 2
(-2)^4 = (-2)^n-1
The bases (-2), cancels out
so we have: 4 = n-1
collect like terms
4-1 = n
3 = n
n= 3
Use the slope form:
m= (y2-y1)/(x2-x1)
Plug in two sets of points from table 4. (0,9) (2,4)
m= (4-9)/(2-0)
m= -5/2 or -2.5
Do the same for the second table. I can't see it very well, so I am assuming that number under 1 is 5. (0,3) and (1,5)
m= (y2-y1)/(x2-x1)
m= (5-3)/(1-0)
m= 2/1 or 2
I hope this helps!
