Step-by-step explanation:
Let the initial population of a community be P0 and the population after time t is P(t).
If the population of a community is known to increase at a rate proportional to the number of people present at time t, this is expressed as:
at t = 5 years, P(t) = 2P0
substitute:
If the population is 9,000 after 3 years
at t = 3, P(t) = 9000
a) Substitute into the formula to get P0
Hence the initial population is approximately 5938.
b) In order to know how fast the population growing at t = 10, we will substitute t = 10 into the formula as shown:
Hence the population of the community after 10 years is approximately 23,746
We have been given an image of a trapezoid. We are asked to find the measure of angle M and N.
We know that bases of trapezoid are parallel and the two angles between two parallel lines are supplementary, so we can set an equation as:
Upon substituting value of y in measure of angle M, we will get:
Therefore, measure of angle M is 110 degrees.
Similarly, we will find the value of angle N as:
Therefore, measure of angle N is 70 degrees.
