Explanation:
Let's find the slope of the table. This will tell us the rate of change.
m = slope
m = (y2-y1)/(x2-x1)
m = (25250 - 26375)/(2 - 1) .... I used the first two rows
m = -1125/1
m = -1125
The slope of -1125 means the plane's altitude is decreasing at a rate of 1125 feet per minute. This is the descent speed.
Since we're told the initial altitude was 27500 ft, this means b = 27500
This means y = mx+b turns into y = -1125x+27500
x is the number of minutes and y is the altitude at time x
As a way to check this, plug in various x values of the table. You should get corresponding y values that match the table. I'll let you do this part.
------------------
Now plug in y = 16250 and solve for x
y = -1125x+27500
16250 = -1125x+27500
-1125x+27500 = 16250
-1125x = 16250-27500
-1125x = -11250
x = -11250/(-1125)
x = 10
It takes 10 minutes after the descent period has started, for the pilot to get to 16,250 ft.
Since the pilot was contacted at the x = 4 minute mark, this means 10-4 = 6 minutes is the duration needed for the pilot to go from 23,000 ft to 16,250 ft.
Quotient=?
The slope can be found using the coordinates of the given point and the y-intercept. The equation of the line is y = -2x - 5.
To write the equation of a line with a given y-intercept and a point, we can use the slope-intercept form:
y = mx + b.
The y-intercept is -5, so the equation becomes:
y = mx - 5.
We also know that the line passes through the point (-3, 1). To find the slope (m), we can use the formula:
m = (y2 - y1) / (x2 - x1). Substituting the coordinates, we get:
m = (1 - (-5)) / (-3 - 0)
= 6 / -3
= -2.
Plugging the slope and y-intercept into the equation, the equation of the line is: y = -2x - 5.

Answer:
A = 4 cm^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 b*h
The base is 4 and the height is 2
A = 1/2 ( 4*2)
A = 1/2*8
A = 4 cm^2
Answer:
4
Step-by-step explanation:
A = BH/2
or Area = Base multiplied by Hieght divided by 2.
(b)4 x (h)2 = 8
8/2 = 4
Answer:
El indicador mencionado en el enunciado indica que la suma de los resultados de las pruebas de razonamiento cualitativo de los estudiantes dividido por la población de los estudiantes arroja ese promedio.
El promedio indica el valor "central" del indicador, no estudia la dispersión de los resultados de las pruebas, es decir, como se distribuye la colección de indicadores.

The calculated value of the area of the parallelogram is 99 square cm
From the question, we have the following parameters that can be used in our computation:
The parallelogram
Where we have
Height = 11 cm
Base = 5 cm + 4 cm = 9 cm
The area of the parallelogram is calculated as
Area = Base * Height
Substitute the known values in the above equation, so, we have the following representation
Area = 11 * 9
Evaluate the product of 11 and 9
So, we have the following representation
Area = 99
Hence, the area of the parallelogram is 99 square cm
