Answer:
66.5 in or 5.5 ft (rounded)
Step-by-step explanation:
Step-by-step explanation:
c²=a²+b²
a²=c²-b²
a²= 15²-9²=225-81=144
a=√144=12
sinΩ=a/c=12/15=4/5
cosΩ=b/c=9/15=3/5
tanΩ=a/b=12/9=4/3
The vertex is a maximum for f(x) and a minimum for g(x). This is because the squared term is never negative.
Because the larger the squared term is, the smaller f(x) is, f(x) is at MOST 5. Similarly, because the larger the squared term is, the larger g(x) is, g(x) is at MOST -3.
Log₃ (-2*(-6)-3)=2
log₃(12-3)=2
log₃9=2
The expanded form of the equation is x^4-24x^3+222x^2-240+960
<h3>Expansion of expression</h3>
Given the expression below;
(x-3)(x-5)(x-7)(x-9)+15
Expand
(x-3)(x-5)(x-7)(x-9) + 15
(x^2-5x-3x+15)(x^2-9x-7x+63) +15
(x^2-8x+15)(x^2-16x+63) + 15
Expand further to have;
x^4-16x^3+63x^2-8x^3+144x^2-504+15x^2-240x+945+15
x^4-24x^3+222x^2-240+960
Hence the expanded form of the equation is x^4-24x^3+222x^2-240+960
