Step-by-step explanation:
The correct answer is B) y=80000(1.03)ˣ.
Population growth is represented using an exponential equation. These equations are of the form
y = a(1+r)ˣ, where y is the total population, a is the initial population, r is the growth rate, and x is the amount of time.
We first find the growth rate. This is the percent of change, which is found by
amount of change/original amount
The amount of change from 2010 to 2011 is 82400-80000=2400. 2400/80000 = 0.03, so r = 0.03.
The growth rate from 2011 to 2012 is (84872-82400)/82400 = 0.03. Checking the others, they are very close to this as well, so we will use this as r.
Our value of a in the equation is the initial population, 80000. This gives us:
y = 80000(1+0.03)ˣ = 80000(1.03)ˣ
Answer:
A
Step-by-step explanation:
Answer:
3, 6, 9
Step-by-step explanation:
To find the first 3 terms , substitute n = 1, 2, 3 into the n th term rule.
a₁ = 3(1) = 3
a₂ = 3(2) = 6
a₃ = 3(3) = 9
The square's side length is 24/7 or 3.428 units if the square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle.
<h3>What is a right-angle triangle?</h3>
It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
First we have to find the line that goes through the points (0, 6) and (8, 0)
(y - 0) = (0-6)/(8-0)(x-8)
y = (-6/8)[x - 8]
Plug y = x
x = (-6/8)[x - 8]
After solving:
x = 24/7 or 3.428
y = 24/7 or 3.428
Thus, the square's side length is 24/7 or 3.428 units if the square is inscribed in a right triangle with leg lengths 6 and 8 such that they have a common right angle.
