1/10 is equal to 100/1000, as that way, both the numerator and the denominator are multiplied by 100.
This works because the number multiplying the top and bottom are equal, therefore resulting in no net change.
The answer is
140/16 =
8.75
The population starts at 2000, so a=2000.
We also know that the population in 3 hours is 1000, so we can setup the equation:
2000 b^3 = 1000
This gets us:
b^3 = 1/2
And taking the cube root of both sides gives us:
b ≈ 0.7937005259841
Rounding that to 4 places, we have:
f(t) = 2000 (0.7937)^t
Answer:
you also have to translate 3 units to the right
Step-by-step explanation:
when you finished your reflections the coordinate of the point is (1, -1) while it should be (4, -4), that means you not only need to move it by 3 down but also to the right.
Show that n is odd →∃m∈ℤ,n2=8m+1
Let k be an integer so that n=2k+1. Then n2=(2k+1)2=4k2+4k+1=2(2k2+2k)+1.
But this isn't equal to 8m+1, so can I change that into 4(2m)+1?
