Answer:
The answer is shown below
Step-by-step explanation:
Let y(t) be the fraction of the population that has heard the rumor at time t and assume that the rate at which the rumor spreads is proportional to the product of the fraction y of the population that has heard the rumor and the fraction 1−y that has not yet heard the rumor.
a)
where k is the constant of proportionality, dy/dt = rate at which the rumor spreads
b)
At t = 2, y = 40% = 0.4
c) At y = 75% = 0.75

d. 0.230769
Answer:
0.23076923
Step-by-step explanation:
I think the question was mistyped. The question seems to be what is 3/13 expressed as a decimal? To do that simply divide de numerator by the denominator and get the answer, which is 0.23076923. In this way, you transformed a fraction into a decimal.

How do you identify the center and radius of a circle?
How do you define the radian measure of an angle?
How are arc length and area of a sector related to proportionality?
Answer:
How do you derive the equation of a circle?
you can reverse the circle formula
How do you identify the center and radius of a circle?
You can identify the center because it is the middle of the circle and the radius can be draw from the center to the round part.
How do you define the radian measure of an angle?
it is the ratio of the length of the arc the angle forms÷the radius of the circle
How are arc length and area of a sector related to proportionality?
sector x radian
area = (r^2 x)/2
arc length = r x
they are not propotional
because Area / arc length = r/2 , (it's not a constant)

Answer:
120 with 4 left
Step-by-step explanation:
482 divided by 4 is 120.5. so you throw 120 apples in each basket and you have 2 left.
Olivia divided the 482 apples she picked from the orchard's largest apple tree evenly into 4 baskets. Each basket contains 120 apples and there are 2 apples left over.
Total apples picked = 482
To determine the number of apples in each basket, we need to divide the total number of apples picked by Olivia, which is 482, by the number of baskets, which is 4.
Using division, 482 divided by 4 equals 120 remainder 2. Therefore, each basket contains 120 apples and there are 2 apples left over.
