Environmentalists estimate an annual population decrease of giraffes in the wild of 3.5% due to development. This can be modeled by the function p(x) = 140,000(0.965)x, where x is the number of years of tracking the populations. Conservationists have developed a sanctuary that has shown the ability to increase the population by 0.85% per year. The increase can be modeled by the function S(p) = p(1.0085)x.
Which function represents S(p(x)), rounded to the nearest ten thousandth?
S(p(x)) = 135,100(0.9732)x
S(p(x)) = 135,100(1.9735)x
S(p(x)) = 140,000(0.9732)x
S(p(x)) = 140,000(1.9735)x
The equation of the function S(p(x)), rounded to the nearest ten thousandth is S(p(x)) = 140,000(0.9732)ˣ option (C) is corrrect.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

B. Function g is the result of f being translated left 2 units and up 4 units.
C. The graph of function f opens upward.
D. The graph of function f opens downward.
E. The graph of function f is compressed by a factor of 2.
Answer: B. Function g is the result of f being translated left 2 units and up 4 units. and C. The graph of function f opens upward.
Step-by-step explanation:
It is translated 2 units to the left and 4 units up because in the function of a(x-h)^2k, h represents the function going left of right and k representing the function going up and down. a represents it stretching if it is greater than 1 and compressing if less than 1 and if it is negative it reflects over the x axis however here nothing changed for the a so it did not stretch nor compress nor reflect over the x axis
Can someone explain powers of imaginary numbers? (like i^2, i^3, i^4, and so on)
The powers of the imaginary number gives:
i² = -1i³ = -ii⁴ = 1i = i⁵i² = i⁶i³ = i⁷i⁴ = i⁸etc...
How the powers of imaginary numbers work?We know that the imaginary number is defined as:
i = √(-1)
If we square it, then we get:
i² = √(-1)² = -1
As the exponent 2 removes the square root.
With the exponent 3 we get:
i³ = √(-1)³ = √(-1)²*√(-1) = -1*i = -i
i³ = -i
Finally, the exponent 4 gives:
i⁴ = i²*i² = (-1)*(-1) = 1
And now the cycle repeats, we will have that:
i = i⁵
i² = i⁶
i³ = i⁷
i⁴ = i⁸
etc...

It is to be noted that the distance between P and ρ is: [tex]\approx[/tex] 15.52
This solution is arrived at using the Line Segment theorem. See further explanation below.
What is the line segment theorem?The length of the line segment connecting two points in a plane is defined as the distance between two points. The method for calculating the distance between two locations is often written as
[tex]d = \sqrt{((x_{2} – x_{1})² + (y_{2} – y_{1})²).} [/tex]
Hence, since we have ρ is to contain two points, we will solve as follows:
Distance between ρ and P where ρ is (0, -3) and (7,4)
we have to multiply the coordinates.
To multiply coordinates, you have to multiply the corresponding values.
That is
[tex]x_{1} \times x_{1} [/tex]
and
[tex]y_{1} \times y_{1}[/tex]
In this case:
x1 = 0
[tex]x_{1} = 0[/tex]
also
[tex]x_{1} = 7[/tex]
[tex]y_{1} = - 3[/tex]
also
[tex]y_{1} = 4[/tex]
Hence, for
[tex]x_{1} = 0 \times 7 = 0[/tex]
for
[tex]y_{1} = - 3 \times 4 = 12[/tex]
Hence, solving for the distance between P and ρ, we'd use coordinates of P as = (4, 3); and coordinates of ρ as = (0, -12)
Recall that distance is given as
[tex]d = \sqrt{((x_{2} – x_{1})² + (y_{2} – y_{1})²).} [/tex]
Hence,
d = √((0-4)² + (-12-3))²)
[tex]d = \sqrt{{(( {0 - 4}^{2} }) + { (- 12 - 3)}^{2} } [/tex]
Expand the brackets
[tex]d = \sqrt{ { - 4}^{2} + ( { - 15}^{2} } )[/tex]

1. You have 5 horses and you feed 4.5 pounds of grain to each in one day. What is the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag?
2. You have 32 heads of horses, and each gets 1.5 pounds of grain per feeding. You feed grain twice a day, once in the morning and once in the evening. If you feed grain that costs $13 per 50lb bag, then is the cost per head per month?
3. You have 12 heads of horses, and each gets 2.5 pounds of grain per feeding. You feed grain twice a day, once in the morning and once in the evening. If you feed grain that costs $13 per 50lb bag, then is the cost per head per month?
Solving the questions from the given equations
1)the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag is $16.2
2) The cost per head per month is $23.4
3) The cost per head per month is $39
What is Equation?
There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables.
1) The grains use feed for one horse = 4.5pound
The cost of 1 bag of grain = $27 per 50lb
The cost of 1lb grain = $0.54
Now the monthly cost of the grain will be:
Cost/head/day x # of days in month = Cost/head/month
$0.54 x 30 = $16.2
Hence, the monthly cost per head to feed them if the grain you feed is $27.00 per 50lb bag is $16.2
2) The amount of grain use to feed for one head = 1.5pound
If the grain is feed twice a day = 1.5 x 2
= 3.0
The cost of the grain = $13 per 50lb
The cost of 1lb grain = 13 / 50
= $0.26
The cost of grain feed in one day = 0.26 x 3
= $0.78
The cost of per head per month =
0.78 x 30 = $23.4
Hence, The cost per head per month is $23.4
3)The amount of grain use to feed for one head = 2.5pound
If the grain is feed twice a day = 2.5 x 2
= 5pounds
The cost of the grain = $13 per 50lb
The cost of 1lb grain = 13 / 50
= $0.26
The cost of grain feed in one day = 0.26 x 5
= $1.3
The cost of per head per month =
1.3 x 30 = $39
Hence, The cost per head per month is $39

The speed of the particle at time t=4 is 5 units.
We are given the x(t) vs time curve.
To find:
Speed of particle at t = 4
We know that the slope of x-t curve represents the speed of the particle.
To calculate the speed of the particle at t = 4, We will calculate the slope of the curve at t = 4
Slope = y₂ -y₁ / x₂ - x₁
Slope = 40 - 10 / 6 - 0
Slope = 30 /6
Slope = 5
From here we can say that the slope of the curve between x = 0 and x = 6 is equal to 5.

At α = 0.05, is there sufficient evidence that state senators are on average younger than 60.35 (the average age Senators in Washington)?
Answer:
There is not sufficient evidence to support the conclusion that senators are average younger than 60.35
Step-by-step explanation:
Given a simple random sample, the size is 40 senators.
Since the relevant statistic is the sample mean, 60.35 years.
Calculate t as:

What is a parallel line?No matter how far we extend a parallel line, it will always remain straight. Take a look at the parallel lines in the following illustration. Lines "p" and "q" are parallel to each other as are lines "a" and "b."
We know that parallel lines have same slope, so the slope of y = 2x - 5 is 2 according the y intercept form, y = mx + b
Now using the point-slope form we will find the line parallel to Point B (6, 8)
y − y₁ = m(x − x₁)
Put m as 2, y₁ as 8 and x₁ as 6, and we wil get
y − 8 = 2(x −6)
y = 2x − 4 or
2 = (y + 4)/x (slope)
We will us point-slope form for point A(n, 4) too
y − 4 = 2(x −n)
y = 2x − 2n + 8 or
2 = (y - 8 + 2n)/x
As slope 2 is same in both points it means their equations are same too
(y + 4)/x = (y - 8 + 2n)/x
Lest solve for n
(y + 4)/x = (y - 8 + 2n)/x
y + 4 = y - 8 + 2n
4 = - 8 + 2n
4 + 8 = 2n
2n = 12
n = 12/2
n = 6
Thus, the value of n for a line that passes through point A(n, 4) and point B(6, 8) and is parallel to y = 2x - 5 is 6.

D has a value of 13 using vertical angles.
What is a vertical angle?
When two lines intersect, the angles that face each other are called vertical angles.Instead of referring to them as being up-down, "vertical" in this context denotes that they share a vertex (corner point).Assuming that C and D constitute vertical angles
The formula is C = (-3x) + 58 and D = x - 2.
We must ascertain what D's measurement is.
Vertical angles are really a pair of opposing angles created when two lines cross.
A and B in the figure represent vertical angles. C and D are also.
Angles vertically are always congruent. Accordingly, in this illustration, A, B, and C, D
Therefore, value of C = D (-3x)+ 58 = x – 2
By assembling,
(-3x )- x = (-2) - 58
By doing more math, 4x = 60 (-4x = - 60)
4 x = 60/4 x = 15 when both sides are divided.
So, ∠D = (x - 2) and
= 15 - 2
So, ∠D = (x - 2) and
