answer:
1 -4 = 3 (-2+1)
Answer:
P(t) = 12e^1.3863k
Step-by-step explanation:
The general exponential equation is represented as;
P(t) = P0e^kt
P(t) is the population of the mice after t years
k is the constant
P0 is the initial population of the mice
t is the time in months
If after one month there are 48 population, then;
P(1) = P0e^k(1)
48 = P0e^k ...... 1
Also if after 2 months there are "192" mice, then;
192 = P0e^2k.... 2
Divide equation 2 by 1;
192/48 = P0e^2k/P0e^k
4 = e^2k-k
4 = e^k
Apply ln to both sides
ln4 = lne^k
k = ln4
k = 1.3863
Substitute e^k into equation 1 to get P0
From 1, 48 = P0e^k
48 = 4P0
P0 = 48/4
P0 = 12
Get the required equation by substituting k = 1.3863 and P0 = 12 into equation 1, we have;
P(t) = 12e^1.3863k
This gives the equation representing the scenario
Answer:
680x + 170
Step-by-step explanation:
calculate the product
4
x170 +170=
680x+ 170
Answer:
Product, twice and area
Step-by-step explanation:
The product is the result of the multiplication of the factors.
Product = answer to a multiplication problem
Twice means multiply by 2
Area is found by multiplying the dimensions of a plane figure.
Answer: 1200 inches long.
Step-by-step explanation:
the enlargement went from 1 inches wide to 80 inches wide.So which means it was being multiply by 80.
so you have to multiply 15 by 80 to find length of the enlargement or how long the enlargement of the design will be.
15 * 80=1200
