Answer:
f(x) = 20,000(1 - 0.06)^x
Step-by-step explanation:
The equation to get exponential decay is: A = P(1 +- r)^t
A = Account Balance
P = Principle Amount
r = interest rate (decimal)
t = Time (years)
So, if you plug in all the variables with the values represented in the word problem, you get: f(x) = 20,000(1 - 0.06)^x
Hope this helps!
Solution:
<h3>(D) nonexistent</h3>
lim <u>cos x + sin (2x) + 1 </u> is =0
x—> π x²+π²
<h3>Step by step explaination : </h3>
Plug in the value x = π :
<u>cos </u><u>π</u><u> + sin (2</u><u>π</u><u>) + 1</u> is
π²+π²
Last ,Simplify <u>cos π + sin (2π) + 1</u> is
π²+π²
<h3 /><h3>
= 0</h3>
so.. what is the coefficient "a"?
well
now, we know, another point on the graph, besides the vertex, we know a y-intercept, that is, 0, -30, that simply means when x = 0, y = -30
now, getting the x-intercepts, is just the zeros, or solution to the quadratic
notice, "y" is 0 on both cases, because, is an x-intercept, or a zero, and when the graph touches the x-axis, "y" is zero
Answer:
A
Step-by-step explanation:
(3n²+2n+4)(2n-1)
to solve this multiply through by using each term in one bracket to multiply all terms in the second bracket to open the bracket.
3n²(2n-1) + 2n(2n-1) +4(2n-1)
6n³-3n² +4n²-2n+8n-4
6n³+n²+6n-4
Hence the correct option is A
