Every single one of those expressions factor. When factored, this is what we have:
. After canceling out like factors, what we are left with is this:
. That means that b = 9, c = 1, and d = -2
Answer:
23.4 units
Step-by-step explanation:
Given the point of the vertices of triangle ABC as A(−5,1), B(2,1), and C(6,4).
The distance (d) between two points X (x₁ , y₁) and Y(x₂, y₂) is given as:
. We can use this to calculate the length of the sides of the triangle. Therefore:
The perimeter of the triangle ABC = AB + AC + BC = 7 + 11.4 + 5 = 23.4 units
Answer:
D is the answer!!
Step-by-step explanation:
so first you see all the numbers then you see that 0.45 is the least then you look to see and you see 2 problems that have 0,45 then you lokk at the second number there and D has 0.75 and you see that D have least to greatest!!
The answer is the first one, (2)
The population model is an exponential decay because it decreases
The exponential model of the population is P = 3000(0.64^1/7)^t
<h3>How to determine the function?</h3>
The population decreases by 0.36 every 7 years.
This means that the function is an exponential decay.
An exponential decay function is represented as:
P = a((1 - r)^1/n)^t
Where:
- a represents the initial value (3000)
- r represents the rate (0.36)
- n represents the number of years the population decreases (7)
- P and t are the variables
So, we have:
P = 3000((1 - 0.36)^1/7)^t
Evaluate the difference
P = 3000(0.64^1/7)^t
Hence, the exponential model of the population is P = 3000(0.64^1/7)^t
