The slope of the new road is zero.
How to find slope?The slope of a line is the change in y with respect to the change in x.
In other words, the slope of a line is rise over run.
Therefore, the new road the city planner wants to build is perpendicular to the the D street.
(5, 1)(5, 4)
slope of D street = 4 - 1 / 5 - 5
slope of D street = 3 / 0
slope of D street = infinity
An infinite slope is simply a vertical line. Therefore, it is only perpendicular to a horizontal line which will have a slope of 0. Hence, the new road should have a slope of 0.

how to graph:-8x-y=8
In order to graph this equation, we first need to find two ordered pairs that are solution to this equation.
To do this, we can choose a value for x and calculate the corresponding value of y.
Choosing x = 0 and x = -1, we have:
[tex]\begin{gathered} x=0\colon \\ -8\cdot0-y=8 \\ 0-y=8 \\ y=-8 \\ \\ x=-1\colon \\ -8\cdot(-1)-y=8 \\ 8-y=8 \\ y=0 \end{gathered}[/tex]Now, graphing the points (0, -8) and (-1, 0) and the line that passes through them, we have:

Find the probability of the following card hands from a 52-card deck. In poker,
aces are either high or low. A bridge hand is made up of 13 cards.
In poker, four of a kind (4 cards of the same value)
O 2.40 x 104
O 2.00 × 10-5
O 1.85 x 10-5
O4.34 x 10-4
Answer: 2.40 * 10^(-4)
This value is approximate.
=====================================================
Explanation:
A four of a kind is where we have 4 cards of the same value, as mentioned in the instructions. For example, we could have 4 queens and some other card, such as a 10 of clubs.
There are 13 cards to pick from for any given suit. Once that card is chosen, the other 3 slots are fixed to whatever that first card is. The fifth slot will have 52-4 = 48 choices.
In short we have 13 choices for the first four cards and 48 choices for the fifth card.
Overall we have 13*48 = 624 different four of kind poker hands.
Let's now calculate how many possible poker hands there can be.
A poker hand consists of 5 cards. I don't know why your teacher mentioned a bridge hand of 13 cards since that's for a different game.
We'll use n = 52 and r = 5 in the nCr combination formula below.
[tex]n C r = \frac{n!}{r!(n-r)!}\\\\52 C 5 = \frac{52!}{5!*(52-5)!}\\\\52 C 5 = \frac{52!}{5!*47!}\\\\52 C 5 = \frac{52*51*50*49*48*47!}{5!*47!}\\\\ 52 C 5 = \frac{52*51*50*49*48}{5!}\\\\ 52 C 5 = \frac{52*51*50*49*48}{5*4*3*2*1}\\\\ 52 C 5 = \frac{311875200}{120}\\\\ 52 C 5 = 2598960\\\\[/tex]
There are 2,598,960 possible five-card poker hands.
624 of those hands are four of a kind, so the probability we want is
624/(2,598,960) = 0.000240 = 2.40 * 10^(-4)
The approximate decimal value 0.000240 converts to 0.0240%

What is an area?Area is amount of space occupied by a two-dimensional figure. In other words, it is quantity that measures the number of unit squares that cover the surface of a closed figure. The standard unit of the area is square units which is generally represented as square inches, square feet, etc.
Word 'area' means a vacant surface. The area of shape is calculated with the help of its length and width. Length is the unidimensional and measured in units such as feet (ft), yards (yd), inches (in), etc. However, area of a shape is a two-dimensional quantity. Hence, it is measured in the square units like square inches or ([tex]in^{2}[/tex]), square feet or ([tex]ft^{2}[/tex]), square yard or ([tex]yd^{2}[/tex]), etc. Most of the objects or the shapes have edges and corners. The length and width of these edges are considered while calculating area of a specific shape.
Since,
Park a= 4926 [tex]km^{2}[/tex]
Park b= (4926-1845) = 3081 [tex]km^{2}[/tex]
Park c= (4006+4926) = 8932 [tex]km^{2}[/tex]

By using the secant line formula, the average rate of change of function f(x) on the interval [3, 11] is equal to 4.
How to determine the average rate of change of a function
In accordance with the statement, we must determine the average rate of change for a given closed interval of the function f(x). Graphically speaking, the average rate of change for this interval is represented by the slope of the secant line passing through the two limits of the interval [a, b], which is found by secant line formula:
m = [f(b) - f(a)] / (b - a)
If we know that a = 3, f(a) = 19, b = 11 and f(b) = 51, then the average rate of change is:
m = (51 - 19) / (11 - 3)
m = 32 / 8
m = 4

To find the equation for a passes through (2, -3).
How to determine an equation of the line parallel to another line
In this question we must derive the equation of the line for a given street and look for another equation of the line parallel to the previous one. Lines are first order polynomials of the form y = m · x + b, where m and b are the slope and the y-intercept, respectively.
Now, According to the question:
Now we present the procedure in detail. First, find the equation of the first line:
5 = 4 · m₁ + b₁ (1)
2 = 3 · m₁ + b₁ (2)
(m₁, b₁) = (3, - 7)
Second, determine the equation of the line parallel to the line found in the previous step: (Please notice that two lines are parallel to each other when they share the same slope but have different y-intercepts)
-3 = 3 · 2 + b₂
b₂ = -3 - 6
b₂ = - 9
Hence, The equation of the line parallel to the first line is y = 3 · x - 9.

D
The number of tablets sold increased each year
More people used a tablet sold by the store in 2017 than they did in 2018.
The maximum number of tablet sales the store made occurred 7 years after 2010
D
The correct statement regarding the function on the table is given by:
D. The maximum number of tablet sales the store made occurred 7 years after 2010
What is the meaning of the function?The meaning of the function is that it gives the number of tablets sold, in thousands, in y years after 2010, hence the variables are given by:
y: number of years after 2010.T(y): number of tablets sold on the respective year.For example, T(-1) = 0 = 17 means that 17,000 were sold in the year of 2009.
There was a single decrease, from 2017 to 2018, that is, year 7 to year 8, hence statement B is false.
For item C, we have no information whether this number is true, hence the statement is false, as the function gives the number of tablets sold at the store, not the number of people using the tablets.
The true statement is given by option D, since f(7) = 130 is the maximum value of the function.
