Side lengths with <span>4 in, 8 in, 3 in.</span> will not form a triangle 'cause we know, that sum of shorter sides must be greater than the longer side but here it's not.
In short, Your Answer would be Option D
Hope this helps!
R = 108/-81 = -144/108 =192/-144 = -4/3
This is a geometric sequence with a common ratio (r) = -4/3
The nth term of a geometric sequence is given by tn = ar^(n-1) where a is the 1st term.
Therefore, the formular for the sequence is f(x) = -81(-4/3)^(x-1)
Answer: C [f(x) = -81(-4/3)^(x-1)]<span><span /></span>
Kate will walk 95 more than 1000 miles in a year the math would be 365x3=1095
First of all let x-1=0
x=1
Therefore,
P(x)=2x^4+4x^3-7x^2-kx+9
P(1)=2(1)^4+4(1)^3-7(1)^2-k(1)+9
2(1)+4(1)-7(1)-k+9=0
2+4-7-k+9=0
15-7-k=0
8-k=0
-k=-8
Therefore,k=8
