Answer:
Step-by-step explanation:
it is divided into 4 rectangles
first rectangle ( 100 cm ^2)
area = l × b
= 10 × 10 = 100 cm^2
second rectangle ( 60 cm^2)
area = l × b
= 6 × 10 = 60 cm^2
third rectangle ( 20 cm^2)
area = l × b
= 2 × 10 = 20 cm^2
fourth rectangle ( 12 cm^2)
area = l × b
= 2 × 6 = 12 cm^2
so total area of the rectangle = 100 + 60 + 20 + 12 cm^2
= 192 cm^2

Angles in a triangle may or may not be congruent.
The values of x and y are 90 and 47, respectively.
From the figure, we have:
This means that, angle x is a right-angle.
So, we have:
Triangle ABC is an isosceles triangle.
So, we have:
The measure of y is then calculated as:
--- sum of angles in a triangle
This gives
Subtract 137 from both sides
Hence, the values of x and y are 90 and 47, respectively.

Applying the properties of Isosceles triangle and the sum of triangle theorem, the values of x and y in the image given are:
Recall the properties of Isosceles Triangle:
An isosceles triangle has equal base angles an two equal legs that are opposite the base angles.
Triangle ABC is an isosceles triangle.
- Therefore:
m<ACD = m<ABD = 47 degrees
Find y:
- Substitute
y = 1/2(180 - (47 + 47))
y = 43 degrees.
Find x:
x = 180 - (y + m<ABD)
- Substitute
x = 180 - (43 + 47) (sum of triangle)
x = 90 degrees
Therefore, applying the properties of Isosceles triangle and the sum of triangle theorem, the values of x and y in the image given are:

Answer:
x - y = -4
Step-by-step explanation:
Standard Form: Ax + By = C
A is non-negative
Step 1: Define equation
y - 3 = (x + 1)
Step 2: Solve to Standard Form
- Add 3 to both sides: y = x + 4
- Subtract x on both sides: y - x = 4
- Factor out negative: -(x - y) = 4
- Divide by -1 on both sides: x - y = -4
-y + (x + 1) = -3 would be the answer in standard form.
Where f(x) represents the height, in feet, of the water from the fountain at different times x, in seconds.
What does the average rate of change of f(x) from x = 2 to x = 5 represent?
a.The water travels an average distance of 4 feet from 2 seconds to 5 seconds.
b.The water travels an average distance of 1 foot from 2 seconds to 5 seconds.
c.The water falls down with an average speed of 2 feet per second from 2 seconds to 5 seconds.
d. The water falls down with an average speed of 1 foot per second from 2 seconds to 5 seconds.
Answers
Therefore, the water falls down with an average speed of 1 foot per second from 2 seconds to 5 seconds.
m = (f( b ) - f ( a )) / ( b - a )
a = 2, b = 5
f ( a ) = f ( 2 ) = - 4 + 12 + 6 = 14
f ( b ) = f ( 5 ) = - 25 + 30 + 6 = 11
m = (11-14) / (5-2) = -3/3 = -1
Answer: D ) The water falls down with an average speed of 1 foot per second from 2 seconds to 5 seconds.

Answer: As the data plan increases, the text messages also increases. It's Perfectly straight line and positive correlation.
Step-by-step explanation:
From the question, we are told that the correlation coefficient for the relationship that exists between the size of cell phone data plan, x, and number of text messages sent, y, is R=+0.97.
This shows that a positive correlation exist between both variables. A positive correlation is a relationship that exist between two variables whereby both variables move in tandem, that is, they move in the same direction. In this equation, a positive correlation exists as one variable increases, the other increases. As data plan increases, the text messages also increases.
