Answer:
Given the initial population of termites = 60
After 7 days the population of termites = 225
Step-by-step explanation:
We have given the initial termites and the population of termites after 7 days. Now we are required to find the exponential growth model that will help to predict the future population of termites.
We have, Y = Ca^x
When the value of x is zero then population (Y) is 60 termites.
Y = Ca^x
60 = Ca^x
Now, Y = 60a^x
At x = 7 days
Y = 225
225 = 60 a^7
a^7 = 225/60
a = 1.2078
Thus, final population will be, Y = 60(1.2078)^x
Answer:
D
Step-by-step explanation:
f(x) =x(x-9)
X(x-9)=0
X2-9x=0
X2-9x+0=0
(X2-9X)
x(x-9)=0
X-9=0
X=9
X+0=0
X=0
3,500 meters bc 3.5 times 1000 meters bc since 1 kilo = 1000 so 3.5 times 1000 = 3,500
Answer:
B, coefficient vertically stretches or compress not horizontally, plus it is negative so x axis dlip
A+B: the matrix with same dimension a A and B, the element in row i and column j is: Aij+Bij
Same for A-B, but with Aij-Bij
