Answer:
The slope is -3
Step-by-step explanation:
Count from A to B downwards which is 3 but since we're counting down it's a negative 3. Then from that spot count how many spaces you are from B which is 1. So its -3/1 which is -3. Basically rise/run
In construction, floor space must be planned for stair cases. If the vertical distance between the first and second floors it's 3.6 m and a contractor is using the standard step pattern of 28 cm wide for 18 cm high and how many steps are needed to get the first to the second floor and how much linear distance will be needed for the staircase? How long would a railing be that was parallel to the steps in the previous question? Use a calculator and round your answer to the nearest hundredth.
The length of the railing that was parallel to the steps is; 6.65 meters
How to use Pythagoras Theorem?Let us first of all convert the distance in meters to centimeters. From unit conversion, we know that 1 meter equals 100 centimeters. Thus;
3.6m * 100cm / 1m = 360cm
Now we calculate the number of steps as;
360 cm / 18 cm = 20 steps
Since each step measures 28 cm, it means that total measure of steps is;
20 * 28 = 560 cm
To calculate the length of the ladder, we must apply Pythagoras theorem: c² = a² + b²
From the question, we can say that;
a = 360; b = 560
Thus;
c² = 360² + 560²
c² = 443200
c = √443200
c = 665.73
Expressing 665.73 cm in meters would give us 6.65 meters.

What ratio is equivalent to 8/6
Answer:
3rd option: 32/24
Step-by-step explanation:
8/6 = 4/3
1st option: Now let's change the denominator to 24:
4/3 ==> ?/24
4/3 =
4*8 / 3*8 = 32/24, not 3/24.
2nd option: Now let's change the numerator to 24:
4/3 ==> 24/?
4/3 =
4*6 / 3*6 = 24/18, not 24/32
24/32 = 3/4, not 4/3 ==> don't get confused by this
3rd option: 32/24 is correct [Look at the explanation for 1st option]
4/3 ==> ?/24
4/3 =
4*8 / 3*8 = 32/24, not 3/24.
Hence, the 3rd option is correct.

The solution is, the percent of error, rounded to the nearest percent is 25%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
given that,
While viewing a herd of cattle on a ranch, Herbert estimated that there were 750 cattle in the herd.
The actual number of cattle in the herd was 600.
now, we have to find the percent of error, rounded to the nearest percent.
so, we get,
Herbert estimated that there were 750 cattle in the herd.
The actual number of cattle in the herd was 600.
so, error = 750 - 600
= 150
so, we get,
the percent of error = 150 * 100 / 600
= 25%
Hence, The solution is, the percent of error, rounded to the nearest percent is 25%.

For the following exercises, determine whether the vector field is conservative and, if it is, find the potential function. 106. F(x, y) = (6x + 5y)i + (5x + 4yj
f(x, y) = 3x + 2y + C
To know if a vector field is conservative, we have to check if it is the gradient of a scalar function.
The gradient of the function f(x, y) is given by
∇f(x, y) = (∂f/∂x, ∂f/∂y)
If a vector field F(x, y) is the gradient of a scalar function f(x, y), then the following conditions must be satisfied:
F(x, y) = ∇f(x, y)
Whether a given vector field satisfies this condition can be checked by taking the partial derivative with respect to x and y.
∂F/∂x = ∂(6x + 5y)/∂x = 6
∂F/∂y = ∂(5x + 4y)/∂y = 4
The partial derivative of a given vector field is the constant, the gradient of the scalar function. So vector fields are conservative and we can find a potential function f(x, y) such that F(x, y) = ∇f(x, y).
To find the potential function, we can integrate the partial derivative of F(x, y) with respect to x and y.
f(x, y) = ∫∂F/∂xdx + ∫∂F/∂ydy
= ∫6dx + ∫4dy
= 3x + 2y + C
where C is the constant of integration. So the potential function for a given vector field is
f(x, y) = 3x + 2y + C

The length of side AB is about 5.87 units.
How to find the side of a right triangle?The triangle ABC is a right angle triangle. A right angle triangle is a triangle that has one of its angles as 90 degrees.
Therefore, let's find the length AB in the right triangle.
Using trigonometric ratios,
cos 33 = adjacent / hypotenuse
Therefore,
Adjacent side = AB
hypotenuse side = 7 units
cos 33° = AB / 7
cross multiply
AB = 7 cos 33
AB = 7 × 0.83867056794

The function g is related to one of the parent functions
g(x) = x^2 – 3
The parent function is:
f(x)= x^2
Use function notation to write g in terms of f.
We can write g in terms of f as: g(x) = f(x) - 3 = x² - 3
What is function?
In mathematics, a function is a relationship between two sets of elements, called the domain and the range, such that each element in the domain is associated with a unique element in the range. In simpler terms, a function is a set of rules that takes an input value and produces a corresponding output value.
To write g in terms of f, we can use function composition, which involves plugging the function f(x) into g(x) wherever we see x.
So, we have:
g(x) = f(x) - 3
where f(x) = x².
Substituting f(x) into g(x), we get:
g(x) = (x²) - 3
Therefore, we can write g in terms of f as:
g(x) = f(x) - 3 = x² - 3.

A list of ordered pairs may or may not represent a function.
The six ordered pairs are: \(\mathbf{(x,y) = \{(0,3),(1,6),(2,12),(3,24),(4,48),(5,96)\}}\).The ordered pair is a function.(a) The ordered pair
Let x represent the number of folds, and y represent the thickness.
So, the first ordered pair is:
\(\mathbf{(x,y) = (0,3)}\)
When x increases by 1, the value of y gets doubled.
So, the six ordered pairs are:
\(\mathbf{(x,y) = \{(0,3),(1,6),(2,12),(3,24),(4,48),(5,96)\}}\)

What is elevation?
The elevation is the height of an object or point above a given reference point, usually sea level. It is often used to describe the height or altitude of a geographic location, such as a mountain peak or a city, and is commonly measured in feet or meters.
In the context of elevation, | -7 | feet would mean the vertical distance between the point at -7 feet and sea level (0 feet).
The vertical distance between two points is calculated by taking the absolute value of the difference between their elevations. So, in this case, the absolute value of -7 is 7, which means the point is 7 feet below sea level.
The correct answer is option (b) The vertical distance between the point at -7 feet and sea level (0 feet).
