Answer:
Step-by-step explanation:
We can write this rate as an ordinary differential equation.
Where a is proportional constant, P the population variable, and t the time.
Integrating each side of the equation.
To find C we need to use the initial condiction, it means evaluae P at t=0.
Now, we use the sentence the population has doubled in 5 years.
We can find "a" in this condition.
Finally, let's find how long will it take to triple.
I hope it helps you!
Answer:
95086
Step-by-step explanation:
We let the population one year ago be x, the relationship between x and the present population is;
(105/100)*x = 104832
This is because the present population exceeds the population one year ago by 5%.
therefore,
1.05*x = 104832
x = 99840
We now let the population two years ago be y, the relationship between y and the population one year ago is;
(105/100)*y = 99840
This is because the population one year ago exceeds the population two years ago by 5%.
Therefore,
1.05*y = 99840
y = 95085.7
Rounding to the nearest whole number;
95086
Answer:
Line :-
A line is defined as a line of points that extends infinitely in two directions. It has one dimension, length. Points that are on the same line are called collinear points.
Line segments :-
A straight line which links two points without extending beyond them. The points P and Q are called the 'endpoints' of the segment. ... The word 'segment' typically means 'a piece' of something, and here it means the piece of a full line, which would normally extend to infinity in both directions.
Ray :-
A part of a line with a start point but no end point (it goes to infinity) Try moving points "A" and "B": line.
Complementary Angles :-
Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Examples: ... 5° and 85° are complementary angles.
Supplementary Angles:-
Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: • 60° and 120° are supplementary angles.
Adjacent Angles :-
Two angles are Adjacent when they have a common side and a common vertex (corner point) and don't overlap. Angle ABC is adjacent to angle CBD. Because: they have a common side (line CB).
Linear Pair :-
A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
Transversal lines :-
In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points. Transversals play a role in establishing whether two other lines in the Euclidean plane are parallel.
Corresponding angles :-
Any pair of angles each of which is on the same side of one of two lines cut by a transversal and on the same side of the transversal.

Answer:
C) a positive correlation
Step-by-step explanation:
<em>More people ⇒ Longer time</em> is a positive correlation between those variables. However, <em>longer time</em> is not the desired outcome.
Rather, <em>shorter time</em> is the desired outcome. The correlation between <em>more people</em> and <em>shorter time</em> is negative. In order to compute that correlation numerically, one would have to define a function that would give a numerical value for "shorter time" that would model the goodness of outcome as time gets shorter.
Answer:
Yes they have the same solutions. Hope this helps! please mark brainliest :)
Step-by-step explanation:
3(x - 2)(x + 3) = 0
x-2=0
x=2
x+3=0
x=-3
(2x - 4)(3x + 9) = 0
2x-4=0
2x=4
x=2
3x+9=0
3x=-9
x=-3
