The nth term of the Sequence: 40, 33, 26, .... is 47 - 7n.
What is Arithmetic Progression?An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same.
Here, we know nth term of the Arithmetic Sequence is
Aₙ = A + (n - 1)D
where, A is first term and D is common difference
A = 40 and D = 33 - 40 = -7
Now, Aₙ = 40 + (n - 1) (-7)
Aₙ = 40 - 7n + 7
Aₙ = 47 - 7n
Thus, the nth term of the Sequence: 40, 33, 26, .... is 47 - 7n.

In order to find the height of any shape given the volume and base area.
Simply divide the volume by the base area.
Here given:
Volume: 9 cm³Base area: 20 cm²Height:
volume ÷ base area = 9 ÷ 20 = 0.45 cmI NEED HELP URGENTLY
Answer:
30 square millimeters
Step-by-step explanation:
3 x 3 = 9
3 x 1 = 3
there are two sides with the area 9 therefore...
9 x 2 = 18
There are four sides with the area 3 therefore...
3 x 4 = 12
Therefore the suface area is

5. A square on the coordinate plane has vertices
at A(-3,0), B(1, 2), C(2,-1), and D(-2,-4). After a
dilation using a scale factor of 3, what are the
new coordinates of D'?
Reason:
Multiply each coordinate of D(-2,-4) by the scale factor 3 to get (-6, -12)
In other words, triple each coordinate of point D.
This trick only works if the center of dilatioin is the origin.

In two or more complete sentences, describe the transformation(s) that take place on the parent function, f(x) = log(x), to achieve the graph of g(x) = log(-2x-4) + 5
Please solve this for me!!!!
Step-by-step explanation:
Howdy there :)
To describe the transformation of the parent logarithmic function, you just need to follow these rules
1. A + on the outside of the parentheses will mean a vertical shift upwards. As such, the transformation is moved 5 units up. If it was -, it would move 5 units down.
2. The inside of the parentheses will result in a horizontal shift right 4 units. The rule to remember is that these kinds of functions follow x(a - b) rules, meaning that when the 4 is subtracted, we are really talking about a positive four, unlike in standard arithmetic. Vice versa, a + 4 will mean a -4 four, since a - -4 is the same as a + 4. As such, we will move in the positive direction (right) on the y axis.
3. Since x is now -2x, we are reflecting about the y axis, meaning the function will switch from left to right or right to left.
4. The 2 in front of it represents a vertical dilation by a factor of 2. This is because our constant, 2, is greater than 1. If the number were in between 0 and 1, it would represent a vertical compression by the constant number.
Solve for x, then find the missing side of the lengths.

calculate the number of subsets and the number of proper subsets for the set.
{1/6, 1/7,1/8,1/9 }
A. 16;15
B.15;16
c.14;15
D.15;14
A set of n elements has 2ⁿ subsets. One of these subsets is the set itself, so this set would have 2ⁿ - 1 proper subsets.
The given set has 4 elements, so it has 2⁴ = 16 subsets and 2⁴ - 1 = 15 proper subsets.
Just to illustrate the claim, we have
• subsets of size 0 (1 of these):
{ } (empty set)
• subsets of size 1 (4 of these):
{1/6}, {1/7}, {1/8}, {1/9}
• subsets of size 2 (6 of these):
{1/6, 1/7}, {1/6, 1/8}, {1/6, 1/9}, {1/7, 1/8}, {1/7, 1/9}, {1/8, 1/9}
• subsets of size 3 (4 of these):
{1/6, 1/7, 1/8}, {1/6, 1/7, 1/9}, {1/6, 1/8, 1/9}, {1/7, 1/8, 1/9}
• subsets of size 4 (1 of these):
{1/6, 1/7, 1/8, 1/9}
and the last one is the only subset that is not a proper subset, because that subset = the set.
The number of subsets are 16 and number of proper subsets for the set are 15. So, correct option is A.
The set {1/6, 1/7, 1/8, 1/9} has 4 elements.
To calculate the number of subsets, including both the proper and improper subsets, you can use the formula 2ⁿ, where n is the number of elements in the set.
So, for this set, there are 2⁴ = 16 subsets.
To calculate the number of proper subsets, you subtract 1 from the total number of subsets (to exclude the empty set).
So, the number of proper subsets is 16 - 1 = 15.
Hence, option A is correct, the number of subsets are 16 and number of proper subsets for the set are 15.

slope for y=2x+3 and y intercept
Answer:
slope = 2, y-intercept = 3
Step-by-step explanation:
» Concepts
All straight lines can follow the slope-intercept form, y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. The slope is the constant rate of change, and the y-intercept is where the line intersects at the y-axis.
» Application
We are asked to find the slope and y-intercept of the equation, y = 2x +3, given the form y = mx + b. As you can see, in the place of m (the slope), there is the number 2, making the slope 2. Then, in the place of b (the y-intercept), there is the number 3, making the y-intercept 3.

Answer:
y = 2x
Step-by-step explanation:
Parallel line share the same slope, therefore we can put any parallel line of y = 2 (x + 1) in equation as: y = 2x + k
As the parallel has to intercept with point (2/3, 1/3), simply put the coordinate into the equation to get value of k
2/3 = 2(1/3) + k
k = 0
Therefore the equation of this parallel line is y = 2x
