determine what doesn't lie in the domain of g(x)=square root 2x-7
For the function g (x) = √ 2 x - 7, the elements that are not included in the domain are ( - ∞, 3.5).
We are given a function:
g (x) = √ 2 x - 7
Now, we need to find what all does not lie in the domain of this function.
For this, we first need to find the domain of the function.
We know that, a square root cannot be negative.
So, we get that:
2 x - 7 ≥ 0
Add 7 to both the sides:
2 x - 7 + 7 ≥ 0 + 7
2 x ≥ 7
Divide both sides by 2:
2 x / 2 ≥ 7 / 2
x ≥ 3.5
Domain = x ≥ 3.5 = [3.5, ∞)
Elements not included in the domain = R - [3.5, ∞) = ( - ∞, 3.5)
Therefore, we get that, for the function g (x) = √ 2 x - 7, the elements that are not included in the domain are ( - ∞, 3.5).

g (9) + h(-14) =
Answer:
15
Step-by-step explanation:
input each of the values (g=9 and h= -14) and solve then add them together
g(9) = 14 - 2/3 (9)
14 - 18/3 (or 6) = 8
h(-14) = -(-14) - 7

The new function resulting from the vertical translation of the function f(x) = x - 2. (Correct choice: C)
How to use a vertical translation in a linear equation
In this problem we find a linear equation, of which we are asked to traslated vertically, a task that can be done by rigid transformation known as vertical translation, which is defined by the following formula:
g(x) = f(x) + k (1)
Where k is the change done on the function along the y axis. Please notice that there is a vertical translation in the + y direction if and only if k > 0, otherwise there is no change (k = 0) or a vertical translation in the - y direction if and only if k < 0.
If we know that f(x) = x - 2 and k = 4, then the resulting expression is:
g(x) = (x - 2) + 4
g(x) = x + (4 - 2)
g(x) = x + 2

Shannon was born on 04/02/2004. How many eight-digit codes could she make using the digits in her birthday?
Answer: 420 different codes.
Step-by-step explanation:
We have eight digits, {0, 0, 0, 0, 2, 2, 4, 4}
For the first digit of the code, we will have 8 options.
For the second we will have 7 options (because we already took one)
for the third one we will have 6 options, and so on.
for the fourth, we will have 5 options
for the fifth, there are 4 options.
for the sixth, there are 3 options.
for the seventh, there are 2 options.
And for the last, there is only one option.
The total number of combinations will be equal to the product between the numbers of options for each digit, then we will have:
C = 8*7*6*5*4*3*2*1
But there is something more, the zeros can permute and will give the same code (So we are counting the same code several times), we have 4 zeros, then the number of permutations of the zeros is:
4*3*2*1 = 24
the 4's also are repeated, two times in this case, the number of permutations is:
2*1 = 2
And the 2's also are repeated, also two times, the number of permutations is:
2*1 = 2
Because we do not want to count these repetitions, we need to divide the total number of combinations by these 3 numbers of permutations
This means that we need to divide the number of different combinations will be:
c = (8*7*6*5*4*3*2*1)/(24*2*2) = 420
So we can conclude that there are 420 different codes.
The number of eight digit codes she can make using the digits in her birthday is; 420 eight digit codes
The 8 digits code of her birth date are;
0, 4, 0, 2, 2, 0, 0, 4
Now, since there are 8 digits, then number of ways of arranging the 8 digits is 8!
Since there are some repetitions, then we have to consider the permutations for them too.
There are four 0's which is 4!
There are two 2's which is 2!
There are two 4's which is 2!
Thus, number of 8 digit codes she can make using the digits on her birthday is;
8!/(4! × 2! × 2!) = 420 eight digit codes

A fruit company sells oranges for 32 cents a pound plus $7.50 per order for shipping. If an order is over 100 pounds, shipping cost is reduced by $1.50. This program is supposed to ask the user for the number of pounds of oranges and then print the cost of the order, but it is all mixed up! Can you put the lines in the right order?
Note that two lines are indented slightly.
Don't worry if you can't solve this one, as we'll cover all of how to do this in the coming weeks. But playing around with this program --- rearranging lines, keeping whole lines together --- and trying to figure out how to make it work will give you good experience in experimenting with Python.
costFruit = pounds * 0.32 #1
else: #2
if pounds <= 100 : #3
pounds = int(input("Enter pounds: ")) #4
print(totalCost) #5
shipping = 6.00 #6
shipping = 7.50 #7
totalCost = costFruit + shipping #8

Answer:
9. x = 12
10. x = 31
Step-by-step explanation:
9. Corresponding angles are equal, so technically you can move that (7x - 20) to be diagonal with the (4x + 16). Along with the corresponding angle, diagonal angles are equal to each other. Therefore you can set (7x - 20) equal to (4x + 16) to find x.
7x - 20 = 4x + 16
Solve
3x - 20 = 16
3x = 36
x = 12
Therefore x is equal to 12
Check:
4(12) + 16
= 64
7(12) - 20
= 64
10. All angles in a triangle have to add up to 180 degrees. Therefore, you can write your equation like this:
x + 2x + 25 + 2x = 180
Combine like terms
5x + 25 = 180
Solve
5x = 155
x = 31
Therefore, x = 31.
Check:
31 + 2(31) + 25 + 2(31) = 180
31 + 62 + 25 + 62 = 180
180 = 180

According to the line of best fit, the time that the temperature will reach 100°c the boiling point of water is a 5.
What is the line of best fit?A straight line that minimizes the gap between it and some data is called a line of best fit. In a scatter plot containing various data points, a relationship is expressed using the line of best fit. It is a result of regression analysis and a tool for forecasting indicators and price changes.
It should be noted that with the increase in time, the temperature increases as well.
Therefore, the time that the temperature will reach 100°c the boiling point of water is a 5.

The coordinates of the vertices of △JKL are J(1, 4) , K(6, 4) , and L(1, 1) .
The coordinates of the vertices of △J′K′L′ are J′(0, −4) , K′(−5, −4) , and L′(0, −1) .
What is the sequence of transformations that maps △JKL to △J′K′L′ ?
reflection across the x-axis
rotation of 180° about the origin
rotation of 90° counterclockwise about the origin
translation 1 unit left
A sequence of transformations that maps △JKL to △J′K′L′ is a _________ followed by a ___________?
Answer:
The sequence of transformations are;
A translation by 1 unit left, followed by a reflection across the x-axis
Step-by-step explanation:
Here, we want to know the transformation sequence
Let us select one point
J(1,4)
to J’(0,-4)
To translate 1 unit right means that we are subtracting the value of 1 from the x-coordinate
That leaves us with (0,4)
To get the change in the y-coordinate value to negative, it means that we have reflected over the x-axis
x-axis reflection turns (x,y) to (x,-y)
So, the sequence of transformations that maps the two is;
A translation by 1 unit left followed by a reflection across the x-axis
Answer:
translation 1 unit left, then 180 degrees
Step-by-step explanation:
J (1,4)
K (6,4)
L (1,1)
Moving it 1 unit left, x unit - 1
J (0,4)
K (5,4)
L (0,1)
Now, rotate it 180 degrees, (x,y) = (-x,-y)
J' (0,-4)
K' (-5,-4)
L' (0,-1).
Hence, the triangle JKL is transformed into triangle J'K'L' when a triangle JKL translates 1 unit to the left and then rotate 180 degrees about the origin.
