The distance between any 2 points (x1,y1) and (x2,y2) is
given
(0,a) and (a,0)
the disance is a√2
Question 1:
The area of a regular hexagon knowing one of its sides by definition is given by:
A = (3 * root (3) * L ^ 2) / (2)
Substituting values we have:
A = (3 * root (3) * (10) ^ 2) / (2)
A = 259.8076211
Rounding off we have:
A = 259.8 squeare feet
Answer:
the area of the floor is:
A = 259.8 squeare feet
option B
Question 2:
We search the are of each sector separately:
For Den:
A1 = (16) * (16)
A1 = 256
For Entrance:
A2 = (4) * (4)
A2 = 16
For Kitchen:
A3 = (12) * (6) + (6) * (6)
A3 = 72 + 36
A3 = 108
The total area is:
A = A1 + A2 + A3
Substituting:
A = 256 + 16 + 108
A = 380 square feet
Answer:
A = 380 square feet
option F
Question 3:
For this case we look for the area of the two shaded triangles.
We have then:
Triangle 1:
A1 = (1/2) * (3) * (4)
A1 = 6
Triangle 2:
A2 = (1/2) * (3) * (4 + 5)
A2 = 13.5
The area of the shaded region is the sum of the areas:
A = A1 + A2
Substituting:
A = 6 + 13.5
A = 19.5 square units
Answer:
A = 19.5 square units
option D
Question 4:
The area of the parallelogram by definition is:
A = (b) * (h)
Where,
b: base
h: height
Substituting values we have:
A = (15) * (15 + 6)
A = 315 square centimeters
Answer:
A = 315 square centimeters
option J
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.
Answer:
The answer is corresponfing angles theorem
Answer:
4x²
Step-by-step explanation:
Your equation is 4x² - 6x² + 7x² - 20x² + 19x².
Since they all have the same variable, simply combine them all to find your answer.
4x² - 6x² + 7x² - 20x² + 19x²
-2x² + 7x² - 20x² + 19x²
5x² - 20x² + 19x²
-15x² + 19x²
4x²
