Answer:

[tex]-5/2[/tex]

Step-by-step explanation:

The slope of the line through the given points is [tex]\frac{5-3}{9-4}=\frac{2}{5}[/tex].

Perpendicular lines have slopes that are negative reciprocals of each other, so the answer is [tex]-5/2[/tex].

Answer:

perpendicular slope = - [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

calculate the slope m of the line using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (9, 5 ) and (x₂, y₂ ) = (4, 3 )

m = [tex]\frac{3-5}{4-9}[/tex] = [tex]\frac{-2}{-5}[/tex] = [tex]\frac{2}{5}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{5} }[/tex] = - [tex]\frac{5}{2}[/tex]

At the first day: the visitor hiked the South Kaibab Trail and the River Trail on one day

so, the length for the first day = 10.1 + 2.7 = 10.1 + 2.7 = 12.8 km

At the second day: the visitor hiked the Bright Angel Trail

so, the length of the second day = 12.6 km

We will answer the questions:

How much farther did she hike the first day than the second day?

it will be = 12.8 - 12.6 = 0.2 kilometers

How much longer was her total route than if she had hiked the North Kaibab Trail?

The total route = 12.8 + 12.6 = 25.4

if she had hiked the North Kaibab Trail, the difference will be = 25.4 - 22.9 =

= 2.5 kilometers

Point C (7 , 52.5) represents a solution of the equation of line y =7.5x

A point is a solution of the equation if and only if it satisfy the line equation.

To check point C is solution o it should satisfy the equation of line y = 7.5x

In point C , x = 7 and y = 52.5

putting x in equation of line and solving for y ,

y = 7.5(7)

y = 52.5

which is true so ,

The coordinates (7 , 52.5) make the equation true

so , (7,52.5) is a solution of y = 7.5x

Solution:

Matthew and Benjamin start from the same spot and drives in opposite directions.

Given:

The formula for speed is given by;

During the journey, they used the same time but moved at different speeds, hence, they will have different distances.

Let the time both used be represented by t

Let Matthew's distance be represented by m

Let Benjamin's distance be represented by b

Thus,

Matthew's distance is calculated below;

Benjamin's distance is calculated below;

The distance covered by the two of them in opposite directions is their distance apart from the starting point.

Hence,

Therefore, after 12.6hours, Matthew and Benjamin were 1272.6 miles apart.

Alloy #13 contains 7% gold, if means that if we need 2.7kg of this alloy, we will have to use a certain amount of gold. Multiply the percent of gold times the mass of alloy to find how much gold we need:

It means that we need 0.189kg of gold.

The alloy we have contains 21% of gold. That means that for every 100kg of alloy there are 21kg of gold, use this ratio to find the mass of alloy we need:

It means that we need 0.9kg of that alloy.

To find how much magic steel we need, we just have to substract this mass from the mass of Alloy #13:

It means that we need 1.8kg of magic steel.

The answer is: The dwarves need 1.8 kg of magic steel and 0.9 kg of their alloy in order to get 2.7 kg of Dragon Alloy #13.

Answer:

(2) 16°C

Step-by-step explanation:

[tex]T(m)=38(0.82)^m+21[/tex]

Find the temperature at the outset ([tex]m=0[/tex]):

[tex]T(0)=38(0.82)^0+21[/tex]

[tex]T(0)=38(1)+21[/tex]

[tex]T(0)=38+21[/tex]

[tex]T(0)=59[/tex]

Since the liquid is cooling, all temperatures equal to or less than 59°C are valid possibilities. However, over time (represented as [tex]m\rightarrow\infty[/tex]), [tex](0.82)^m[/tex] is reduced towards zero and, as such, [tex]38(0.82)^m[/tex] will be reduced towards zero. All that will remain is [tex]T(m)=21[/tex], which makes it the horizontal asymptote. This is shown in the attached graph.

Therefore, since 16°C falls below the asymptote, it does not represent a temperature that the liquid reaches as it cools down.

Using the unit circle:

The values of x and y are -5 and 2 respectively

What is Substitution Method to Solve Linear Equation in Two Variables?
The substitution technique is one of the algebraic methods for solving a system of linear equations in two variables. In this procedure, we get the value of any variable by isolating it on one side of the equation and taking every other term on the other side.

Solution:

The problem is in the step one,

Given: -5x - y = 23

3x - y = -17

You've done the question using substraction method while it waas asked to solve by substitution method.

from equation 1 we can write -y = 23 + 5x

substituting -y in equation 2

3x + 23 + 5x = -17

8x = -40

this implies x = -5 and thus, y = 2

The difference between the heights of two kites is 27 feet.

What is height difference?

Given that length and height refer to a shape's length and height, respectively, respectively, there is a very clear distinction between the two. In a plane, length is the measure that is horizontal, whereas height is the measure that is vertical. Length, breadth, and height are crucial geometrical dimensions used to describe shapes.

A person's inherited genetic makeup accounts for about 80% of the normal variation in height, with the remaining 20% of the height difference coming from environmental factors like diet and upbringing.

Let, Dara's kite is flying 67 feet high. Jill's is flying 40 feet high.

So, the difference between the height of two kites is,

67 feet - 40 feet = 27 feet.

Hence, the difference between heights of kites is, 27 feet.

The line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5? is y = 2x - 13.

Calculation:-

The equation of a line is y = mx + c, m is the gradient and c is the intercept

The line passes through points 4 and -5, x is 4 and y is -5

-5 = 4m + c

When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1

x + 2y = 5

2y = -x + 5

y = (-1/2 * x) + 5

therefore m = -1/2

m1 * m2 = -1

m * -1/2 = -1

-m = -2 , therefore m = 2

-5 = 4 * 2 + c

c = -5 - 8, which is -13

Therefore the equation for the line is y = 2x - 13.

To determine if a point is on a line you can simply substitute the x and y coordinates into the equation. Another way to solve the problem would be to graph the line and see if it falls on the line. Plugging in will give which is a true statement, so it is on the line. Only one line can pass through a single point.

The perimeter and the area of the ground are 101.5 m and 620.125 m², respectively.

We have a ground. The shape of the ground is a rectangle. The length and breadth of the rectangular ground are 30.25 m and 20.5 m, respectively. We need to find the perimeter and the area of the rectangular ground.

Let the perimeter and the area of the ground be denoted by the variables "P" and "A", respectively. The formulas for the perimeter and area of a rectangle are used below.

P = 2×(L + B)

P = 2×(30.25 + 20.5)

P = 2×50.75

P = 101.5

Hence, the perimeter of the rectangular ground is 101.5 meters.

A = L×B

A = 30.25×20.5

A = 620.125

Hence, the area of the rectangular ground is 620.125 square meters.
