Answer: whats your question?
Step-by-step explanation:
Well any number that would round to 30 has to be over 25 so if that's all the information they give you, the number can we any where from 25 to 29.999... Also saying that it could be a different number
Answer:
226.78579
Step-by-step explanation
first, find k in 90(3^kx)
90(e^0) = 90 [when time is 0 years, the population is 90]
180=90(e^k3), 2=e^3k
ln2 = 3k, k=(ln2)/3
90(e^4(ln2)/3) = 90(e^ln(16)/3)
it is about 226.78579
Answer:
see below
Step-by-step explanation:
sin x cos x = cot x
We need to show a counter example
Let's use 30 degrees
sin 30 cos 30 = cot 30
1/2 * sqrt(3) /2 = sqrt(3)
sqrt(3)/4 = sqrt(3)
not true
