A species of animal is discovered on an island. Suppose that the population size P(t) of the species can be modeled by the following function, where time t is measured in years.
P(t) =800/1+ 3e^-0.29t.
Find the initial population size of the species and the population size after 10 years. Round your answers to the nearest whole number as necessary.
Answers
Answer:
The initial population is 200
The population after 10 years is 687
Step-by-step explanation:
Given
[tex]P(t) =\frac{800}{1+ 3e^{-0.29t.}}[/tex]
Solving (a): The initial population
Here:
[tex]t = 0[/tex]
Substitute 0 for t in P(t)
[tex]P(0) =\frac{800}{1+ 3e^{-0.29*0}}[/tex]
[tex]P(0) =\frac{800}{1+ 3e^{0}}[/tex]
[tex]P(0) =\frac{800}{1+ 3*1}[/tex]
[tex]P(0) =\frac{800}{1+ 3}[/tex]
[tex]P(0) =\frac{800}{4}[/tex]
[tex]P(0) =200[/tex]
The initial population is 200
Solving (b): Population after 10 years.
Here
[tex]t = 10[/tex]
Substitute 10 for t in P(t)
[tex]P(10) =\frac{800}{1+ 3e^{-0.29*10}}[/tex]
[tex]P(10) =\frac{800}{1+ 3e^{-2.9}}[/tex]
[tex]P(10) =\frac{800}{1+ 3*0.055}[/tex]
[tex]P(10) =\frac{800}{1+ 0.165}[/tex]
[tex]P(10) =\frac{800}{1.165}[/tex]
[tex]P(10) =687[/tex] -- approximated.
The population after 10 years is 687

A bag of garden soil weighs 44 pounds and holds 5 cubic feet. Find the weight of 15 bags in kilograms and the volume of 15 bags in cubic yards.
Answers
Answer:
weight=660 pounds
volume=75 cubic feet
Step-by-step explanation:
44 × 15 = 660
5 × 15 = 75
The weight of 15 bags of garden soil is approximately 297.9 kilograms.The volume of 15 bags of garden soil is approximately 2.78 cubic yards.
To find the weight of 15 bags of garden soil in kilograms, we can use the conversion factor that 1 pound is equal to 0.45359237 kilograms.
Weight of 15 bags in kilograms = 44 pounds/bag * 15 bags * 0.45359237 kg/pound
Weight of 15 bags in kilograms ≈ 297.9 kilograms
Therefore, the weight of 15 bags of garden soil is approximately 297.9 kilograms.
To find the volume of 15 bags of garden soil in cubic yards, we need to first convert the volume of each bag from cubic feet to cubic yards. There are 3 feet in a yard, so 1 cubic yard is equal to 3 feet by 3 feet by 3 feet, which is 27 cubic feet.
Volume of 15 bags in cubic yards = (5 cubic feet/bag * 15 bags) / 27 cubic feet/yard
Volume of 15 bags in cubic yards ≈ 2.78 cubic yards
Therefore, the volume of 15 bags of garden soil is approximately 2.78 cubic yards.

s(x)=2x-2
t(x)=3x
Write the expressions for (s-t)(x) and (s+t)(x) and evaluate (s⋅t)(-1)
Can't seem to figure it out
Answers
Answer:
Step-by-step explanation:
Given functions are,
s(x) = 2x - 2
t(x) = 3x
(s - t)(x) = (2x - 2) - 3x
= -x - 2
= -(x + 2)
(s + t)(x) = (2x - 2) + 3x
= 5x - 2
(s . t)(x) = (2x - 2)(3x)
= 6x² - 6x
(s . t)(-1) = 6(-1)² - 6(-1)
= 6 + 6

Answer:
31°
Step-by-step explanation:
<Y + <X = 180° [being co-interior angles ]
s + 91° + 2s - 4° = 180°
3s + 87° = 180°
3s = 180° - 87°
3s = 93°
s = 93° /3
s = 31°

Answer:
[tex]\displaystyle 31[/tex]
Step-by-step explanation:
Angles Y and X form a linear pair, therefore you use the Linear Pair Theorem to solve for x:
[tex]\displaystyle 180° = [2s - 4]° + [s + 91]° → 180° = [87 + 3s]° → 93 = 3s; 31 = s[/tex]

What is the equation of a parallel line to y=-5x+2 that passes through the point (-1, 4)?
Answers
Answer:
y=-5x-1
Step-by-step explanation:
If parallel lines, then the slope is the same.
y=-5x+b
To solve for b, plug in (-1,4)
(4)=-5(-1)+b
4=5+b
-1=b **Subtract 5 from both sides**

Answers
Answer:
[tex](rs)(4) = 8[/tex]
Step-by-step explanation:
Given
[tex]r(x) = 2\sqrt{x[/tex]
[tex]s(x) = \sqrt x[/tex]
Required
Determine [tex](rs)(4)[/tex]
In functions:
[tex](fg)(x) = f(x) * g(x)[/tex]
This implies that:
[tex](rs)(x) = r(x) * s(x)[/tex]
Substitute values for r(x) and s(x)
[tex](rs)(x) = 2\sqrt{x} * \sqrt{x}[/tex]
[tex](rs)(x) = 2(\sqrt{x})^2[/tex]
[tex](rs)(x) = 2x[/tex]
Substitute 4 for x
[tex](rs)(4) = 2 * 4[/tex]
[tex](rs)(4) = 8[/tex]
