Answer:
All of those which summed are more that the third side, so the second is the only possible answer.
Step-by-step explanation:
4+8 = 12 which is greather than 10
Sn=n/2[2a+(n-1)d]
s7 means n=7
a7=7/2[2(13)+(7-1)(3)]=7/2(44)=154

I hope this is right! And go on your test! :)
Answer:
Step-by-step explanation:
You want to set up a system. We are given some points fo we can set up inputs and outputs. F(0) = 5, given by point (0,5). and F(3)=135, given by point (3,135). The exponential function general equation is F(x)= a(b)^x. plug in out functions into the general equation to get a(b)^0=5 and a(b)^3=135. Then you simplify and solve for a. In the equation a*b^0=5, anything to the power of 0 is 1. so a*1=5. Therefore a=5. we plug in the a to the second equation to find b. 5*b^3=135. b^3=27. b=3 from simplifying. Therefore, the equation should be 5(3)^x. THATS IT!
