The natural resources of an island limit the growth of the population. The population of the island is given by the logistic equation where t is the number of years after 1980. What is the limiting value of the population?
Answer:
The correct option is (a) 3759.
Step-by-step explanation:
The complete question is:
The natural resources of an island limit the growth of the population. The population of the island is given by the logistic equation [tex]P(t)=\frac{3759}{1+3.94e^{-0.38t}}[/tex]where t is the number of years after 1980. What is the limiting value of the population?
(a) 3759
(b) 23
(c) 761
(d) 1017
Solution:
The limiting value is the value of the function P (t) for t → ∞.
As t → ∞, the expression [tex](3.94e^{-0.38t})[/tex] → 0.
Thus, making the denominator of P (t) 1.
So, the limiting value of the population is, 3759.
Thus, the correct option is (a) 3759.
One circle has a circumference of 123 cm. Another circle has a circumference of 32 cm. What is the ratio of the radius of the
smaller circle to the radius of the larger circle?
3:8
8:3
1:3
3:1
Answer:
1:3
Step-by-step explanation:
First find the measure of radius for both circles:
Circle 1:
2 x pi x r = 123
r = 123 divided by 6.28 = 19.58
Circle 2:
2 x pi x r = 32
r = 32 divided by 6.28 = 5.09
So, Ratio:
5.09 : 19.58
Approximately 1:3 ( 6:18)
Answer: 1:3
Step-by-step explanation:
Cir. of the bigger circle = 123 cm
r = C / 2π
r = 123 / 2π = 19.58
Cir of smaller circle = 32 cm
r = 32 / 2π = 5.09
Ratio = 5.09 : 19.58
= 1:3

The length of the hypotenuse is 13.9, the base is 8, and the other side is 16. The top angle is 60 degrees and the bottom right angle is 30 degrees. A right triangle is shown. The length of the hypotenuse is 13.9, the base is 16, and the other side is 8. The top angle is 60 degrees and the bottom right angle is 30 degrees. A right triangle is shown. The length of the hypotenuse is 16, the base is 13.9, and the other side is 8. The top angle is 60 degrees and the bottom right angle is 30 degrees.
Answer:
A right triangle is shown. The length of the hypotenuse is 16, the base is 13.9, and the other side is 8. The top angle is 60 degrees and the bottom right angle is 30 degrees.
Step-by-step explanation:
The measures of the angles of in a triangle should correspond to the length size of the side opposite each angle in a triangle.
In simple terms, this means that the larger the measure of an angle, the longer the length of the side opposite that angle. Therefore, the smallest measure of an the 3 angles in the triangle should correspond with the shortest length.
Therefore, the triangle with the correct side length would be "A right triangle is shown. The length of the hypotenuse is 16, the base is 13.9, and the other side is 8. The top angle is 60 degrees and the bottom right angle is 30 degrees." Check the attachment below to see how each side length corresponds with each angle opposite them.

Answer:
x = 117°
Step-by-step explanation:
The angle inside the triangle and 101° are adjacent and supplementary, thus
angle inside triangle = 180° - 101° = 79°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
x is an exterior angle of the triangle , thus
x = 38° + 79° = 117°
Answer:
x = 117
Step-by-step explanation:
Exterior angle is equal to the sum of opposite interior angles
101 = 38 + y(unknown interior angle)
y = 101-38
y = 63
Now,
x = 180-y (Angles on a straight line)
x = 180-63
x = 117
What are the measures of angles M and N?
m
m
m
m < M = 119° and m
Answer:
m<M = 113 deg
m<N = 61 deg
Step-by-step explanation:
In an inscribed quadrilateral, opposite angles are supplementary.
m<M + m<K = 180
m<N + m<L = 180
m<M + 67 = 180
m<M = 113
m<N + 119 = 180
m<N = 61
Some one help me pls asp
Answer:
C
Step-by-step explanation:
[tex]\csc \theta= 1\dfrac{1}{4} \\\\\\\dfrac{1}{\sin\theta}=\dfrac{5}{4}[/tex]
Take the reciprocal of both sides:
[tex]\sin \theta =\dfrac{4}{5}[/tex]
You can now imagine a right triangle where the length of the side opposite this angle has a length of 4 and the hypotenuse has a length of 5. The third side by the Pythagorean theorem must therefore have a length of 3. The cosine of an angle is the length of the adjacent side divided by the length of the hypotenuse, or in this case:
[tex]\pm \dfrac{3}{5}[/tex]
Therefore, the correct answer is choice C. Hope this helps!
Evaluate the expression 3.14(a2 + ab) when a = 4 and b = 2. (Input decimals only, such as 12.71, as the answer.) will pick brainleiest!
Answer:
75.36
Step-by-step explanation:
3.14 (a2 + ab)
Substitute a = 4 and b = 2 into the equation:
3.14 (4^2 + 4*2)
= 3.14 (16 + 8)
= 3.14 (24)
= 75.36
Answer:
75.36
Step-by-step explanation:
=> (3.14)(a²+ab)
Putting a = 4, b = 2
=> [tex](3.14)[(4)^2+(4)(2)][/tex]
=> [tex](3.14)(16+8)[/tex]

Answer:
B. 4 StartRoot 2 EndRoot iStep-by-step explanation:
Given the surd function √-2 and √-18, we are to fund the sum of both values.
Taking the sum:
= √-2 + √-18
= (√2 * √-1)+ (√18 *√-1)
from complex numbers, √-1) = i
The expression becomes
= √2 i+ √18 i
= √2 i+ √9*2 i
= √2 i+ 3√2 i
= 4 √2 i
= √-2 + √-18 = 4 √2 i

Answer:
The lines are parallel
Step-by-step explanation:
x - y = 2
Solving for y
-y = -x+2
y = x -2
And the other equation is
y = x+1
These are both in slope intercept form
We notice that the slopes are both 1, but the y intercepts are different
That means the lines are parallel, but have different y intercepts
En un consultorio medico infanfil se consultas mensualmente a 160 pacientes si la razon de cada 8 paciente 5 son niñas A ¿cuantos niños se connsulta al mes ?
Answer: 60 of the patients are boys.
Step-by-step explanation: According to what is described, 5 in 8 patients are girls, then: 8 - 5 = 3, i.e., 3 in 8 are boys.
Mathematically the proportionality is [tex]\frac{3}{8}[/tex]
If 160 patients have appointments per month and [tex]\frac{3}{8}[/tex] are boys:
160.[tex]\frac{3}{8}[/tex] = 60
Per month, 60 boys have appointments at the medical office.

Kanu and Ikedi shared 270 in such a way that 2/5 of Ikedi's share is equal to 1/2 of kanu's. Find their shares.
Answer:
Step-by-step explanation:
We'll solve this with a system of equations. The first equation says that K's shares plus I's shares total 270; therefore,
K + I = 270
The second equation talks about the ratios of their shares.
2/5 I = 1/2 K We'll solve for K by multiplying both sides by 2:
4/5 I = K Now we'll sub that in for K to the first equation:
[tex]\frac{4}{5}I+I=270[/tex] and
[tex]\frac{4}{5}I+\frac{5}{5}I=270[/tex] and
[tex]\frac{9}{5}I=270[/tex] Now we'll solve for I, the number of shares that Ikedi has. Multiply both sides by 5 to get
[tex]9I=1350[/tex] then divide both sides by 9 to get
[tex]I=150[/tex]
Ikedi has 150 shares. Sub that back into the first equation to solve for K:
K + 150 = 270 so
K = 120

x-1 divided by X^3-3x^2-x+3
Answer:
1 / (x + 1)(x - 3).
Step-by-step explanation:
x^3-3x^2-x+3
= x^2(x - 3) - 1(x - 3
= (x^2 - 1)(x - 3)
= (x - 1)(x + 1)(x - 3)
So x - 1 divided by x^3 - 3x^2 - x + 3
= (x - 1) / (x - 1)(x + 1)(x - 3)
= 1 / (x + 1)(x - 3).

What expression represents the value of v?
Answer:
D
Step-by-Step Explanation:
Please refer to the attachment.
As shown, when deconstructing the (largest) right triangle, we get two similar triangles.
Remember that corresponding sides of similar are proportional. Therefore, we can write the following proportion:
[tex]\displaystyle \frac{v}{w+z}=\frac{z}{v}[/tex]
Cross-multiply to produce:
[tex]z(w+z)=v^2[/tex]
And taking the square root of both sides gives:
[tex]v=\sqrt{z(w+z)}[/tex]
Therefore, our answer is D.
Answer:
It is D (v=Square root of ((w)(w+z))

if x√3=30 then what is x
Answer:
x = 10 sqrt(3)
Step-by-step explanation:
x√3=30
Divide each side by the sqrt(3)
x sqrt(3) / sqrt(3) = 30/ sqrt(3)
x = 30 / sqrt(3)
x = 30 / sqrt(3) * sqrt(3)/ sqrt(3)
x = 30 sqrt(3)/3
x = 10 sqrt(3)

What is the slope of the line on the graph below 1/5 1/3 3 or 5
Answer:
1/3
Step-by-step explanation:
We are given to find the slope of the line shown on the graph.
We note that
the line on the graph passes through the points (3, -4) and (6, -3).
The slope of a straight line passing through the points (a, b) and (c, d) is given by
m=\dfrac{d-b}{c-a}.m=
c−a
d−b
.
Therefore, the slope of the given line is
\begin{lgathered}m=\dfrac{-3-(-4)}{6-3}\\\\\\\Rightarrow m=\dfrac{-3+4}{3}\\\\\\\Rightarrow m=\dfrac{1}{3}.\end{lgathered}
m=
6−3
−3−(−4)
⇒m=

−3+4
⇒m=

.
Thus, the required slope of the line is \dfrac{1}{3}.
