8 gorrilas
Explanation:
The ratio of monkeys to gorrila = 5:2
This means there are 5 monkeys for every 2 gorrilas
when there are 20 monkeys,
let the number of gorrilas = x
5 monkeys = 2 gorrilas
20 monkeys = x
cross multiply:
5(x) = 20(2)
5x = 40
divide both sides by 5:
5x/5 = 40/5
x = 8
Hence, if there were 20 monkeys, we would have 8 gorrilas.

Hello there!
To find the increasing intervals for this graph just based on the equation, we should find the turning points first.
Take the derivative of f(x)...
f(x)=-x²+3x+8
f'(x)=-2x+3
Set f'(x) equal to 0...
0=-2x+3
-3=-2x
3/2=x
This means that the x-value of our turning point is 3/2. Now we need to analyze the equation to figure out the end behavior of this graph as x approaches infinity and negative infinity.
Since the leading coefficient is -1, as x approaches ∞, f(x) approaches -∞ Because the exponent of the leading term is even, the end behavior of f(x) as x approaches -∞ is also -∞.
This means that the interval by which this parabola is increasing is...
(-∞,3/2)
PLEASE DON'T include 3/2 on the increasing interval because it's a turning point. The slope of the tangent line to the turning point is 0 so the graph isn't increasing OR decreasing at this point.
I really hope this helps!
Best wishes :)
