x>?
The domain of the (goh)(x) will be [6, ∞).
What are domain and range?The domain means all the possible values of x and the range means all the possible values of y.
The functions are given below.
g(x) = √(x - 4) and h(x) = 2x - 8
Then the function f of g (x) will be
(goh)(x) = g(h(x))
(goh)(x) = √((2x - 8) - 4)

The results of a study indicate that the mean weight of adult skunks in an area is between 4.3 kg and 4.9 kg. What is the study’s margin of error?
Since we are given the range of the area, the margin of error can be calculated by firstly calculating the difference of the range and dividing by 2. This is expressed in this formula:
Margin of error = ± (Upper range – Lower range) / 2
Margin of error = ± (4.9 kg – 4.3 kg) /2
Margin of error = ± 0.3 kg

Indicate the equation of the line that is the perpendicular bisector of the segment with endpoints (4, 1) and (2, -5).
Answer:
The correct answer is x+3y=-3
Step-by-step explanation:
My fist step to solving this question would be to find the mid-point of the given line. The mid point of (4,1) and (2,-5) is (3,-2). The mid point is where the perpendicular bisector connects or bisects the given segment. My second step would be to graph the two given points and to connect them, forming a line. This way, I would know the slope of the line and then I would be able to find the slope of the perpendicular bisector, since the slope for perpendicular lines is the opposite reciprocal of the given line. In doing this, I discovered that the slope of the segment with the given endpoints is 3 which means that the slope of the perpendicular bisector will be x. So, so far we've got a point of intersection and a slope which is all we need to formulate the equation of the line that we are looking for.
In the end, our answer will be x+3y=-3.

John must have at least 289 test points to pass his math class. He already has test scores of 72, 78, and 70. Which inequality will tell him at least how many more points he needs to pass the class
A. 72 + 78 + 70 + x < 289
B. 72 + 78 + 70 + x ≤ 289
C. 72 + 78 + 70 + x ≥ 289
D. 72 + 78 + 70 + x > 289
Answer:
C. [tex]72+78+70+x\geq 289[/tex]
Step-by-step explanation:
Let x represent the number of points John needs to pass the class.
We have been that John must have at least 289 test points to pass his math class. He already has test scores of 72, 78, and 70.
After scoring x points on John's total score would be [tex]72+78+70+x[/tex].
Since John needs at least 289 test points to pass his math class, so the total number of points should be greater than or equal to 289.
We can represent this information in an inequality as:
[tex]72+78+70+x\geq 289[/tex]
Therefore, the inequality [tex]72+78+70+x\geq 289[/tex] represents the number of more points John needs to pass the class.

The temperature of a chemical reaction ranges between −10 degrees Celsius and 50 degrees Celsius. The temperature is at its lowest point when t = 0, and the reaction completes 1 cycle during a 6-hour period. What is a cosine function that models this reaction?
f(t) = −30 cos (pi/3) t + 20
f(t) = −60 cos (pi/3) t + 30
f(t) = 30 cos (6t) + 20
f(t) = 60 cos (6t) + 30
Answer:
Option 1 - [tex]f(t)=-30 sin(\frac{\pi}{3}t)+20[/tex]
Step-by-step explanation:
Given : The temperature of a chemical reaction ranges between −10 degrees Celsius and 50 degrees Celsius. The temperature is at its lowest point when t = 0, and the reaction completes 1 cycle during a 6-hour period.
To find : What is a cosine function that models this reaction?
Solution :
General form of cosine function is [tex]f(x)=A cos(Bx)+C[/tex]
Where A is the amplitude
[tex]B=\frac{2\pi}{\text{Period}}[/tex]
C is the midline
Now, We have given
The temperature of a chemical reaction ranges between −10 degrees Celsius and 50 degrees Celsius.
A is the average of temperature,
i.e, [tex]A=\frac{-10-50}{2}=-30[/tex]
Period of 1 cycle is 6 hour
So, [tex]B=\frac{2\pi}{6}=\frac{\pi}{3}[/tex]
The temperature is at its lowest point when t = 0 and we know lowest point is -10
So, [tex]f(t)=A\cos t+C[/tex]
[tex]-10=-30\cos 0+C[/tex]
[tex]C=20[/tex]
Substituting the values we get,
The cosine function is [tex]f(t)=-30 sin(\frac{\pi}{3}t)+20[/tex]
Therefore, Option 1 is correct.
The function $f$ satisfies \[f(x) + f(2x + y) + 5 x y = f(3x - y) + 2x^2 + 1\]for all real numbers $x$, $y$. determine the value of $f(10)$.
A hospital gives a survey to all surgical patients asking them to rate the quality of their hospital experience. One month after surgery, the hospital contacts the patients again to ask if there were any complications from the surgery. Last year, the results of the surveys showed that of the patients who had a poor hospital experience, 23% had post-surgical complications. What conclusion can be drawn from this study?
Solutions:
As given in the question , patients who had a poor hospital experience, 23% had post-surgical complications.
Option (C) appears the right choice from my point of view which is c) Most patients who have a poor hospital experience also have post-surgical complications.
The reason being , that the patients who suffer from these complications have experienced badly in the last hospital where they were diagnosed or cured.
Answer:
a) Some patients who have a poor hospital experience also have post-surgical complications.
Step-by-step explanation:
Given is :
Last year, the results of the surveys showed that of the patients who had a poor hospital experience, 23% had post-surgical complications.
The conclusion that can be drawn from this study is - Some patients who have a poor hospital experience also have post-surgical complications.
If we turn the percentage in figures, we can see that almost 2.3 person or 2 patients out of 10 patients have a poor hospital experience and also have post-surgical complications.
So, this is a low value that is why the correct answer is Some patients who have a poor hospital experience also have post-surgical complications.

If you take a certain number and add a zero to the right of it and subtract the result from 143, you'll get the tripled imagined number. What is the imagined number?
Final answer:
To find the imagined number, we need to follow the given steps: add a zero to the original number, subtract it from 143, and set the result equal to the tripled imagined number.
Explanation:
To find the imagined number in this question, we need to follow the given steps. Let's assume the original number is x. Adding a zero to the right of it gives us 10x. Subtracting this result from 143 gives us 143 - 10x. According to the question, this result is equal to the tripled imagined number, so we have 143 - 10x = 3x. To solve for x, we can rearrange the equation as 143 = 13x, and then divide both sides by 13. Therefore, the imagined number, x, is 11.

The graphs of f(x) = 10x and its translation, g(x), are shown.
What is the equation of g(x)?
g(x) = 10x – 3
g(x) = 10x + 3
g(x) = 10x – 3
g(x) = 10x + 3
Answer:
The equation for the function g(x) is:
[tex]g(x)=(10)^{x-3}[/tex]
Step-by-step explanation:
We are given graphs of two functions f(x) and g(x).
The function f(x) is an exponential function and is given by:
[tex]f(x)=(10)^x[/tex]
Now, we are asked to find the equation for the transformed function g(x).
We could see that the graph of the function g(x) passes through (3,1),(4,10) , (5,100) and so on.
This means that the equation or the expression for the function g(x) is given by:
[tex]g(x)=(10)^{x-3}[/tex]
( Since, when x=3 we have:
[tex]g(x)=(10)^{3-3}=10^0=1[/tex]
when x=4 we have:
[tex]g(x)=(10)^{4-3}\\\\g(x)=(10)^{1}\\\\g(x)=10[/tex]
and so on)
Answer:
(x)=(10)^(x-3)

One more than 16 times the population density of New Mexico equals the population density of Texas to the nearest whole number , what is New Mexico's populations density ?
To solve for New Mexico's population density, we represent the given condition in a mathematical equation: '1 + 16x = y', where 'x' is the population density of New Mexico and 'y' is the Texas population density. We solve for 'x' by rearranging the equation to: 'x = (y - 1) / 16'. The specific population density of New Mexico can be calculated when the density of Texas is known.
Explanation:The seemingly complicated question is basically one about algebra. It can be expressed as: '1 + 16x = y', where 'x' is the population density of New Mexico and 'y' is the population density of Texas. To find 'x' (New Mexico's population density) given the value for 'y', we need to rearrange the equation by subtracting 1 from both sides to get '16x = y - 1', and then divide both sides by 16 to solve for 'x': 'x = (y - 1) / 16'.
Without specific population density values for Texas ('y'), we cannot compute an actual numeric value for New Mexico's population density. However, we can use this equation to perform the necessary calculations once we know the population density (per square mile, for instance) of Texas.
