The other Washington DC landmark with coordinates (8,-10) is located in the fourth quadrant of the map.

To determine in which quadrant of the map a point with coordinates (8,-10) is located, we need to look at the signs of the x and y coordinates.

Since the x-coordinate (8) is positive and the y-coordinate (-10) is negative, this point is located in the fourth quadrant.

In general, the four quadrants of a Cartesian coordinate system are divided by the x and y-axes.

The first quadrant is located in the upper right-hand corner and contains points with positive x and y coordinates.

The second quadrant is located in the upper left-hand corner and contains points with negative x and positive y coordinates.

The third quadrant is located in the lower left-hand corner and contains points with negative x and y coordinates.

Finally, the fourth quadrant is located in the lower right-hand corner and contains points with positive x and negative y coordinates.

The slope of the new road based on the information given is 0.

A slope of a line is defined in mathematics as the change in y coordinate with respect to the change in the x coordinate. The net change in y-coordinate is denoted by  Δy, while the net change in x-coordinate is denoted by  Δx. Where "m" represents the slope of a line. As a result, tanθ  represents the slope of a line.

The slope of d street line is tan(90)

[if the angle made by a line with x axis is  then, the slope of that line will be tan() ]

Here, the angle made by the d street line with x axis is 90 degrees. If a road is to be built which is perpendicular to d street , it should make 0 degrees i.e, it should be parallel to x axis. So, the slope of new road will be tan(0) = 0

The average rate of change of the function f(x)=9/-3x+4, on the interval [3,5] is 1.

A function is a process or set of instructions that takes inputs, performs a specific task, and produces an output. Functions are key components of programming languages, allowing the coder to create complex commands with simple instructions. For example, a function can be used to add two numbers together or to generate a random number. Functions can also be combined to create more complex sequences of instructions.

The average rate of change of the function f(x)=9/-3x+4, on the interval [3,5] can be determined by taking the difference of the output values of the function at the endpoints of the interval, and then dividing it by the difference of the input values of the interval.

The output of the function at x=3 is f(3)=9/-3*3 +4 = -5,
and the output of the function at x=5 is f(5)=9/-3*5 +4 = -3.

Therefore, the difference of the output values is f(5)-f(3) = -3 - (-5) = 2

The difference of the input values is 5-3 = 2

Therefore, the average rate of change of the function on the interval [3,5] is f(5)-f(3) / (5-3) = 2/2 = 1.

Hence, the average rate of change of the function f(x)=9/-3x+4, on the interval [3,5] is 1.

The positive sums are:

B. 5 + (–2)

C. –3 + 4

E. –2 + 4

Step-by-step explanation:

We can simply observe the sums to conclude that the sum will be positive or negative.

A. –5 + (–2)

We can see that both numbers are negative, the sum of two nu=egative numbers is also negative.

-5+(-2) = -5-2 = -7

B. 5 + (–2)

The number with greater magnitude is positive so the sum will also be positive.

5 + (–2) = 5-2 = 3

C. –3 + 4

The number with greater magnitude is positive so the sum will also be positive.

-3+4 = 1

D. 0 + (–3)

The number with greater magnitude is negative so the sum will also be negative.

= 0-3 = -3

E. –2 + 4

The number with greater magnitude is positive so the sum will also be positive.

-2+4 = 2

Hence,

The positive sums are:

B. 5 + (–2)

C. –3 + 4

E. –2 + 4

The cost per pound of rib steak is $2.40 and the cost per pound of hamburger meat is $1.25.

To find the cost per pound of each type of meat, we can set up a system of equations based on the given information.

Let's denote the cost per pound of rib steak as 'x' and the cost per pound of hamburger meat as 'y'.

From the first statement, we know that:

2x + 6y = 12.30 ---(Equation 1)

From the second statement, we know that:

3x + 2y = 9.70 ---(Equation 2)

Now we can solve this system of equations to find the values of 'x' and 'y'.

Multiplying Equation 1 by 3 and Equation 2 by 2 to eliminate the 'x' term, we get:

6x + 18y = 36.90 ---(Equation 3)

6x + 4y = 19.40 ---(Equation 4)

Subtracting Equation 4 from Equation 3, we get:

14y = 17.50

Dividing both sides by 14, we find:

y = 1.25

Substituting the value of 'y' back into Equation 1, we can solve for 'x':

2x + 6(1.25) = 12.30

2x + 7.50 = 12.30

2x = 4.80

x = 2.40

Therefore, the cost per pound of rib steak is $2.40 and the cost per pound of hamburger meat is $1.25.

Based on the given scale, if Houston and Dallas are 1.6 centimeters apart on the map, the estimated distance between the two cities is approximately 242.1 miles.

To determine the distance between Houston, TX and Dallas, TX using the given scale, we can set up a proportion using the distances on the map and the actual distances.

Let's denote the distance between Houston and Dallas as "x" (in miles).

According to the scale provided, 2.3 centimeters on the map represents a distance of 348 miles. This can be expressed as:

2.3 cm / 348 miles = 1.6 cm / x miles

To find the value of "x," we can cross-multiply and solve the equation:

(2.3 cm) * (x miles) = (1.6 cm) * (348 miles)

2.3x = 556.8

Divide both sides by 2.3 to isolate "x":

x = 556.8 / 2.3

x ≈ 242.0869565

Therefore, based on the given scale, if Houston and Dallas are 1.6 centimeters apart on the map, the estimated distance between the two cities is approximately 242.1 miles.

Please note that this is an approximation based on the given scale and the assumption that the scale is linear and consistent throughout the map. Actual distances may vary and should be verified using more accurate measurements or reliable sources.

Fibonacci sequence is a sequence, in which each number is the sum of the two preceding ones. The numbers in the Fibonacci sequence is the Fibonacci numbers.

Suppose a newly-born pair of rabbits, one male and one female, are put in a field.

Let \(f_{1},f_{2},f_{3} ,........f_{12}\) represents the number of rabbit in the month 1, month2,....month12.

i.e., \(f_{1} =2, f_{2} =2\)

At the end of its second month a female can produce another pair of

rabbits. i.e., \(f_{3}=4\).

At the end of third month a parent female produce one pair and the daughter female produce one pair. i.e., \(f_{4} = 8.\)

Similarly it goes on for 12 months.

Using fibonacii sequence, the general term is,

\(f_{n} =f_{n-1}+f_{n-2}\)

for 5th month

\(f_{5} =f_{4} +f_{3} =8+4=12\)

\(f_{6} =f_{5} +f_{4} =12+8=20\)

Step-by-step explanation:

⅓Log₁₀(125/8) – 2Log₁₀(2/5) + Log₁₀(80/125)

The above expression can be simplified as follow:

⅓Log(125/8) – 2Log(2/5) + Log(80/125)

Recall:

a LogM = Log Mᵃ

Therefore,

⅓Log(125/8) – 2Log(2/5) + Log(80/125)

= Log(125/8)¹/³ – Log(2/5)² + Log(80/125)

= Log(5/2) – Log(4/25) + Log(16/25)

Recall:

Log M – Log N = Log M/N

Log(5/2) – Log(4/25) = Log (5/2 ÷ 4/25)

Log(5/2) – Log(4/25) = Log (5/2 × 25/4)

Log(5/2) – Log(4/25) = Log (125/8)

Therefore,

Log(5/2) – Log(4/25) + Log(16/25)

= Log (125/8) + Log(16/25)

Recall:

Log M + Log N = Log MN

Log (125/8) + Log(16/25)

= Log (125/8 × 16/25)

= Log 10

= Log₁₀10 = 1

Therefore,

⅓Log(125/8) – 2Log(2/5) + Log(80/125)
