This sequence is:
a(n)=-11(-4)^(n-1)
The sum of the sequence is:
s(n)=-11(1--4^n)/(1--4)
s(n)=-11(1--4^n)/5
so for the first seven terms
s(7)=-11(1--4^7)/5
s(7)=-11(1+16384)/5
s(7)=-11(16385)/5
s(7)=-36047 B.
Answer:
f(x) = x(x +4)(x -3)
Step-by-step explanation:
Zeros at -4, 0, and 3 tell you the factorization is ...
f(x) = a(x +4)(x)(x -3)
Then f(2) = a(6)(2)(-1) = -12a.
The graph shows f(2) = -12, so a=1. That makes the function rule:
f(x) = x(x +4)(x -3)
__
If you want it multiplied out, it will be
f(x) = x^3 +x^2 -12x

X= 7 I already solve it before check other questions.
Answer:
x=17
Step-by-step explanation:
So the outside angle is basically is an addition of the two angles given to you. 60°+2x°=94°.
