Describe the graph of the function g by transformations of the base function f.
(Graph and Answers pictured!)
Answer:
Option (3)
Step-by-step explanation:
Base function in the graph is 'f' and the transformed form of the function 'f' is function 'g'.
Since, the base function 'f' is reflected across the x-axis,
h(x) = -f(x)
Followed by the translation by 3 units downwards,
g(x) = h(x) - 3
= -f(x) - 3
Therefore, function in the form of g(x) = -f(x) - 3 will be the answer.
Option (3) is the correct option.
Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26. What is
the solution set of this problem?
0 (-0, -21)
O (-0, -21]
o [-21, +00)
O (21, +00)
Answer:
5 × (x + 27) ≥ 6 × (x + 26).
Step-by-step explanation:
The solution set of " Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26" is (-∞, -21]
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
For this case, let the number in consideration be 'x', then according to the condition specified, we get:
The sum of a number and 27 = x+27Five times the sum of a number and 27 = [tex]5(x+27)[/tex]The sum of that number and 26 = x + 26Six times the sum of that number and 26 = [tex]6(x+26)[/tex]Also, we get:
Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26 as:
[tex]5(x+27) \geq 6(x+26)[/tex]
Expanding and taking x on one side:
[tex]5x+135 \geq 6x+156\\135-156 \geq x \\\\x \leq -21[/tex]
Thus, the considered statement is true for all the numbers which is smaller or equal to -21. Symbolically, the solution set is: (-∞, -21]
The square bracket shows that the -21 is included in the interval. And the interval (-∞, -21] is set of all real numbers smaller or equal to -21.
Thus, the solution set of " Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26" is (-∞, -21]

Identify the level of measurement of the data, and explain what is wrong with the given calculation. In a survey, the favorite sports of respondents are identified as 1 for basketball, 2 for baseball, 3 for football, and 4 for anything else. The average (mean) is calculated for 517 respondents and the result is 1.5.
Answer:
(a) Nominal data
(b) Calculating the mean is wrong
Step-by-step explanation:
Given
[tex]1 \to[/tex] Basketball
[tex]2 \to[/tex] Baseball
[tex]3 \to[/tex] Football
[tex]4 \to[/tex] Others
Solving (a): The level of measurement
In the given parameters, digit 1 to 4 are used to label each of the given sport.
When such labels are used, the type of data is nominal.
Solving (b): The error
In (a), we identified that the level of measurement is nominal. This implies that, the data are not counted, but instead they are categorized.
And as such, the mean of the data cannot be calculated.

What is the product of the rational expressions shown below? Make sure your
answer is in reduced form. X+1/x-4 • 5x/x+1?
Answer:
5x / (x - 4)
Step-by-step explanation:
(x + 1)/(x - 4) • 5x/(x + 1)
Method 1:
Cancel out x + 1
Leaving 5x/(x - 4)
Method 2:
(x + 1)/(x - 4) • 5x/(x + 1)
Multiply numerator and denominator separately
= 5x(x + 1) / (x - 4)(x + 1)
Cancel out (x + 1) in the numerator and (x + 1) in the denominator
= 5x / (x - 4)
Therefore,
(x + 1)/(x - 4) • 5x/(x + 1) = 5x / (x - 4)

A = 1/2 ( 3) * ( 2/3)
A = 3/2* 2/3
A =1
Answer:
1 ft^2
Step-by-step explanation:
The formula for the area of a triangle is as follows, a=b*h*1/2
Now, let's plug in the values to match your question. A=3*2/3*1/2
Lastly, solve. 3*2/3=6/3=2. Then divide 2 by 1/2=1.
Add the unit to make it 1 ft^2

A bag contains 6 black, 4 blue, and 8 white marbles. What is the probability that a marble drawn from the bag will be white?
a.1/18
b.2/5
c.4/9
d.4/5
Answer:
C.4/9
Step-by-step explanation:
You add the black marbles, blue marbles, and the white marbles together, which equal 18. Out of the 18 marbles, 8 of them are white so it would be 8/18.
but you have to simplify it. 8 and 18 have 2 as the greatest common factor. 8 divided by 2 is 4 and 18 divided by 2 is 9. Finally its 4/9 since you cant simplify it even more.

Let D be the ordered set of all possible words (not just English words, all strings of letters of arbitrary length) using the Latin alphabet using only lower case letters. The order is the lexicographic order as in a dictionary (e.g. aaa < dog < door). Let A be the subset of D containing the words whose first letter is 'a' (e.g. a A, abcd ∈ A). Show that A has a supremum and find what it is.
Answer:
To show that A has a supremum is given as,
Step-by-step explanation:
Because A is that the set of all letters from the dictionary starting with the letter 'a'. And as after set A, there'll be a group containing all the opposite words .. so there exists some x during a such every other letter during a comes before it. So it's none aside from a word starting with the letter b therefore the supremum of the set A is letter b.

A plane Airport on Tuesday morning for a 755-mile,6- hour trip. For the first part of the tripthe average speed was 105 mphFor the remainder of the trip the average speed was 130 mph . How long did the plane fly at each speed ?
Answer:
105 miles / hour for 1 hour
130 miles / hour for 5 hours
Step-by-step explanation:
Part A
speed = 105 mphdistance = xtime = yPart B
speed = 130 mphdistance = 755 miles - xtime = 6 hr - yplane Part A: x = 105 *y
Plane Part B: 755 - x = 130*(6 - y)
Put 105*y into the equation for plane B
755 - 105*y = 130*(6- y) Remove brackets on the the right.
755 - 105y = 780 - 130y Add 130y to both sides
755 - 105y + 130y = 780 Combine left
755 + 25y = 780 Subtract 755 from both sides
25y = 780 - 755
25y = 25 Divide by 25
y = 25/25
y = 1
The plane travelled 1 hour at 105 mile / hour
The plane travelled 5 hour at 130 mile / hour
Check
1 hour for a distance of 1 hr * 105 mph = 105 mile
5 hour for a distance of 5 hr*130 mph = 650 miles
Total distance = 755 miles
Remark
This is a very neat problem. I don't think I've ever seen this variation. It is a little long, but it is well worth your time.

The quadratic regression equation that models these data is y = - 0.34x ^ 2 + 4.43x + 3.46 Using the quadratic regression equation what was the predicted profit in year 8? A. $ 17.14 million B. $ 17 million C. $ 16.8 million D. $16 million
Answer:
A. $ 17.14 million.
Step-by-step explanation:
Profit:
The profit, in millions of dollars, on year x, is given by:
[tex]y(x) = -0.34x^2 + 4.43x + 3.46[/tex]
Year 8
This is y(8). So
[tex]y(8) = -0.34(8^2) + 4.43(8) + 3.46 = 17.14[/tex]
$17.14 million, option A.

9514 1404 393
Answer:
30 mL
Step-by-step explanation:
The meaning of 60% solution is ...
alcohol/(total volume) = 0.60
You are told the amount of alcohol is 18 mL, so you have ...
(18 mL)/(total volume) = 0.60
Multiplying by total volume gives ...
18 mL = 0.60 × (total volume)
Then dividing by 0.60, you have ...
(18 mL)/0.60 = total volume = 30 mL
_____
Additional comment
You need to apply what you know about the real world to consider whether your answer makes any sense. If alcohol is a little more than half of the volume, and the amount of alcohol is 18 mL, then the total volume cannot be less than 18 mL. In fact, you expect it to be not quite double 18 mL.
An answer of 10.8 mL makes no sense in this context. You cannot have less total solution than you have of something that makes up a part of the total solution.
Each time Caroline goes shopping she decides whether or not to buy fruit.
The probability that she does buy fruit is 0.7.
Independently, she then decides whether or not to buy a CD, with a probability of 0.6 that she does buy a CD.
Work out the probability that she buys fruit or buys a CD or both.
The probability that she buys fruit or buys a CD is 1.3.
The probability that she buys fruit and buys a CD is 0.42.
What are the probabilities?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that she buys fruit or buys a CD = 0.7 + 0.6 = 1.3
The probability that she buys fruit and buys a CD = 0.7 X 0.6 = 0.42

3. What shape is a prism?
Answer:rectangular
Step-by-step explanation:
Answer:
TRIANGULAR
Step-by-step explanation:
A prism is a triangular-shaped piece of glass. The white light that reaches the prism contains all of the colors of the visible spectrum even though you can’t see them. As the white light passes through the edge or boundary of the prism, the light waves refract. Each of the different wavelengths contained in the white light refracts differently and results in a different color. The white light is broken up by the prism into all the colors of rainbow. The longest wavelength bends (refracts) the least and is red. The shortest wavelength bends the most and is violet.

find the equation of line parallel to y=-2x+1 and passing through the point (2,4)
Answer:
[tex]y=-2x+8[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x is 0)Parallel lines always have the same slopes1) Determine the slope (m)
[tex]y=-2x+1[/tex]
The given line has a slope of -2. Because parallel lines always have equal slopes, we know that the line parallel to this would also have a slope of -2. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-2x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=-2x+b[/tex]
Plug in the given point (2,4) to solve for b
[tex]4=-2(2)+b\\4=-4+b[/tex]
Add 4 to both sides to isolate b
[tex]4+4=-4+b+4\\8=b[/tex]
Therefore, the y-intercept of the line is 8. Plug this back into [tex]y=-2x+b[/tex]:
[tex]y=-2x+8[/tex]
