Answer:
The answer is
<h2>1225</h2>
Step-by-step explanation:
4x² + 5 - 6x³ + 3x⁴ - x
x = - 4
Substitute the value of x into the expression
That's
4(-4)² + 5 - 6(-4)³ + 3( 4 )⁴ - - 4
Simplify
4(16) + 5 - 6( -64) + 3( 256) + 4
64 + 5 + 384 + 768 + 4
We have the final answer as
<h3>1225</h3>

f(x)=x²-1
g(x)=2x-3
f(x)*g(x)=(x²-1)*(2x-3)-----------> <span>this function exists for all real numbers</span>
the answer is the interval (-∞,∞)
using a graph tool see the attached figure
A.) P(t) = 130t - 0.4t^4 + 1200
The population is maximum when P'(t) = 0
P'(t) = 130 - 1.6t^3 = 0
1.6t^3 = 130
t^3 = 81.25
t = ∛81.25 = 4.3 months.
Maximum population P(t)max = 130(4.3) - 0.4(4.3)^4 + 1200 = 1,622
b.) The rabbit population will disappear when P(t) = 0
P(t) = 130t - 0.4t^4 + 1200 = 0
t ≈ 8.7 months
7.5 x 10⁹
For standard form, move the decimal 9 places. Since the 9 is positive, move it to the right. (If it was negative 9, you would move it to the left)
