Answer:
3. increases by 228 cats
Step-by-step explanation:
The rate of the increase in cats is given by:
as this is the rate, we can write it as:
here t is the time in years. and S in the size of the colony
we're asked about the increase in size between the 10th and 4th year. So we need to know the sizes of the colony in those years.
We can find this out by integration. The above equation can be seen as a differential equation. Hence,
S(t) is the function of the size of the colony at time t. We need to find the differences of sizes between t = 10 and t = 4. Basically,
The C's will cancel out
Conjugate of the denominator is -2-7i
Answer:
37.5%
Step-by-step explanation:
The computation is shown below:
Here we assume that the 1st, 2nd and 3rd child be the triplet and it could be either a girl or boy
Now
B = Boy
G = Girl
The possible triplets are
(BBB) (BBG) (BGB) (BGG) (GBB) (GBG) (GGB) (GGG)
These are 8 triplets
Now find the sets that involves 2 boys and a girl
(BBG) (BGB) (GBB)
Now the probability is
P = 3 ÷ 8
= 37.5%
Answer:
2+2i
Step-by-step explanation:
(-5+2i)+(3+4)
-5+3+4+2i
-5+7+2i
2+2i
