Answer:
= 5
Step-by-step explanation:
The recursive rule for a geometric sequence is
= a
where a is the first term and r the common ration
Here
r = - 10 ÷ 5 = 20 ÷ - 10 = - 2 and a = 5, thus
= 5
The answer is C. C is not a proportion.
Hope this helps!
The answer:
by definition, an exponential function with base c is defined by <span>h (x) = ac^x</span><span>
where a ≠0, c > 0 , b ≠1, and x is any real number.</span>
The base, c, is a constant and the exponent, x<span>, is a variable.
</span>so if we have f(x)=3(3\8)^2x, this equivalent to f(x)=3(3\8)^y(x),
where y (x)=2x, <span>
therefore, the base is 3/8, and the variable is the function </span>y (x)=2x,
