The only option that is true for the function g is; Option D: g(3) = 18
How to interpret the domain and range of a function?The function, g, has;
Domain; -1 ≤ x ≤ 4
Range: 0 ≤ g(x) ≤ 18
g(-1) = 2 and g(2) = 8
Then the following properties must hold to be true;
The value(s) of x must be between -1 and 4
The values of g(x) must be between 0 and 18.
We consider the options and state why they are true or otherwise.
Option A: g(5) = 12
When x = 5, g(5) = 12. This contradicts property 1 stated above and as such it is not true.
Option B: g(1) = -2
When x = 1, g(x) = -2. This contradicts property 2 stated above and as such, it is not true.
Option C: g(2) = 4
When x = 2, g(2) = 4. However by property 4 stated above, g(2)=9. Therefore, we can say that it is not true.
Option D: g(3) = 18
When x =3 means that its domain lies between -1 and 4 and its range lies between 0 and 18.
Therefore, Option D is true.

The answer of [tex]\sqrt[4]{125a^{4} }[/tex] is 3.34a. The solution has been obtained by using the concept of exponents.
What is an exponent?
The exponent of a number shows that how many times a particular number has been multiplied by itself. For instance, the number 2^4 means that we are multiplying the number 2 itself by four times. It is enlarged to 2*2*2*2. An exponent is also known as a number's power. One may use a whole number, fraction, negative number, or decimal.
We are given [tex]\sqrt[4]{125a^{4} }[/tex]
This can be also written as (125a^4)^1/4
Splitting the power, we get
⇒[tex]a^{4^{1/4} } 125^{1/4}[/tex]
⇒a 125^0.25
⇒a 3.34

how does the graph of f(x)=2^x+2 compare to the graph of g(x)=2^x +2
Answer: The graph of f(x) = 2^x and g(x) = 2^x +2 are the same.
Explanation: The functions f(x) = 2^x and g(x) = 2^x + 2 are identical. The only difference between them is the constant term in the second function. This constant term does not change the shape, direction or the relative position of the graph of the function, it only shifts the graph along the y-axis. Because both functions have the same base, the graphs will have the same shape, direction and relative position, regardless of the constant term.

This statement is False.
The formula provided in the statement is used to calculate the variance of the sample mean difference between two independent samples, but it is not necessarily true that the sample variances, and , are independent of one another.
The sample variances are calculated based on the data from their respective samples, and thus their relationship will depend on the specific data and the underlying population distributions.
For example, let's consider two samples of size n = 25, one from a normal population with mean 100 and variance 10, and another one from a normal population with mean 110 and variance 20. The sample variances for each sample are:

Roberto and Maeko open a pet store and start with 5 hamsters for sale. Hamster populations usually triple every cycle. One cycle is equal to 4 months. Write an equation in function notation to represent the change in the number of hamsters as a function of the cycle number, c. Explain how you determined your equation.
The number of hamsters as a function of the cycle number, c, can be represented by the equation:
f(c) = 5 * 3^c
This equation was determined by the fact that the population triples every cycle and the starting number of hamsters is 5. The function notation is f(c) which represents the number of hamsters as a function of the cycle number. The base of the equation is 3, which represents the rate at which the population triples. The exponent is c, which represents the cycle number. The coefficient is 5, which represents the starting number of hamsters.
Prove whether the quadrilateral is a parallelogram using the slope formula:

Parallelograms are quadrilaterals with two sets of parallel sides
Slope Formula: y2-y1/x2-x1
A quadrilateral with two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.

a-ba? +da+b+Dab? - b
The long division problem can be used to prove the formula for factoring the difference of two perfect cubes (a-b)(a²+ab+b²).
The difference of two perfect cubes: a³-b³ = (a-b)(a²+ab+b²)
let the two perfect cubes be a³ and b³. Factoring the difference between these two perfect cubes we have: a³ - b³
First, we need to factorize (a-b)³:
(a-b)³ = (a-b) (a-b)²
(a-b)³ = (a-b)(a²-2ab+b²)
(a-b)³ = a³-2a²b+ab²-a²b+2ab²-b³
(a-b)³ = a³-b³-2a²b-a²b+ab²+2ab²
(a-b)³ = a³-b³ - 3a²b+3ab²
(a-b)³ = (a³-b³) -3ab(a-b)
Then we will make a³-b³ the subject of the formula from the result equation;
a³-b³ = (a-b)³+ 3ab(a-b)
a³-b³ = a-b{(a-b)²+3ab}
a³-b³ = a-b{a²+b²-2ab+3ab}
a³-b³ = (a-b)(a²+b²+ab)
a³-b³ = (a-b)(a²+ab+b²)

If the vehicle has 10 gallons of fuel left, it has driven 600 miles.
What is the equation?The term "equation" refers to mathematical statements with at least two terms that contain variables or integers that are equal.
The amount of gas in the tank should be x gallons, and the distance travelled by car should be d miles.
Due to the car's 16-gallon fuel tank
So, 16 - x would be the remaining fuel in the tank.
It gets 85 miles per gallon of gas when travelling on a highway.
⇒ d = (16-x)85
if the tank still holds 10 gallons of fuel
In the equation above, if x = 10, we get

What is Area of Rectangle?The area of Rectangle is length times of width.
This is a simple calculus problem but it can be solved without calculus, as follows:
let L=length of the pen and W = width
2(L + W) = 20
L + W = 10
L = 10 - W
Let A = area of the pen
A = Length × Width = 10W - W²
Sketch this parabola which has a positive maximum which occurs at W = 10/2
This means the area is maximum when w = 2, in other words the maximum area occurs when the rectangle is a square.

Answer:
w = 11 , x = 25
Step-by-step explanation:
for Δ ABC ≅ Δ TUV, then corresponding sides must be congruent, that is
AB = TU and BC = UV ( using these to create 2 equations )
- 9x + 20w + 89 = 4w + x + 15 ( subtract 4w + x + 15 from both sides )
- 10x + 16w + 74 = 0 → (1)
and
x + w + 41 = - 18w + 11x ( subtract - 18w + 11x from both sides )
- 10x + 19w + 41 = 0 → (2)
multiplying (2) by - 1 and adding to (1) will eliminate x
10x - 19w - 41 = 0 → (3)
add (1) and (3) term by term to eliminate x
0 - 3w + 33 = 0 ( subtract 33 from both sides )
- 3w = - 33 ( divide both sides by - 3 )
w = 11
substitute w = 11 into either of the 2 equations and solve for x
substituting into (1)
- 10x + 16(11) + 74 = 0
- 10x + 176 + 74 = 0
- 10x + 250 = 0 ( subtract 250 from both sides )
- 10x = - 250 ( divide both sides by - 10 )
x = 25
thus the values x = 25 and w = 11 will make the triangles congruent
How much water must be added to 7 gallons of a 8% insecticide solution to reduce the concentration to 7%?
1 gallon of water must be added to 7 gallons of an 8% insecticide solution to reduce the concentration to 7%.
Let x = amount of water required
7 gallons + x gallons = (x + 7) gallons of mixture
For x gallons of water, we have 0 gallons of insecticide
For 7 gallons of 8% insecticide solution, we have 0.08(7)=0.56 gallons of insecticide
According to the question, we get the equation as follows
0.07(x + 7) = 0.56
7(x + 7) = 56
x + 7 = 8
x = 1 gallon
Therefore, the amount of water that needs to be added to 7 gallons of an 8% insecticide solution to reduce the concentration to 7% is 1 gallon.

400x(9x10 to the power of 15)
Answer: 3.6e+18
Step-by-step explanation: (400 x 9 = 3,600) 10 to the power of 15= 1,000,000,000,000,000 or quadrillion. 9x1,000,000,000,000,000=9e+15x400=3.6e+18
the ages of 32 recruits in the police academy are normally distributed with a mean of 27 and a standard deviation of 2.
label the normal curve
Mean is 27 and SD is 2 then the normal curve with highest range would be at domain 27.
What is mean?The mean is the average of a set of numbers. It is calculated by adding all the numbers in the set together, and then dividing by the number of values in the set. It is calculated by adding up all the numbers in the set, dividing by how many values there are in the set, and then multiplying by that number. The average of a group of numbers is called the mean.
Mean is 27 and SD is 2
a) P(23<x<27)= P((23-27)/2<z<(27-27)/2)=P(-2<z<0)=P(z<0)-P(z<-2) or P(z<0)-(1-P(z<2))
From normal distribution table we get 0.5-(1-0.9772)=0.4772
b) P(x>31)=P(z>(31-27)/2)=P(z>2) or 1-P(z<2)=1-0.9772=0.0228
c) P(x<29)= P(z<(29-27)/2)=P(z<1)=0.8413
