Answer:
Approximately 12.04 units.
Step-by-step explanation:
The find the distance between any two points, we can use the distance formula, which is:
We have the points (2,7) and (-6,-2). Let's let (2,7) be (x₁, y₁) and let's let (-6, -2) be (x₂, y₂). Substitute:
Subtract:
Square:
Add:
Approximate
So, the distance between (2,7) and (-6,-2) is approximately 12.04 units.
And we're done!
Answer:
d=5.656854
Step-by-step explanation:
d=√ ( 4 − 8 ) 2 + (− 7 − (− 3 ) ) 2
d=√ ( − 4 ) 2 + ( − 4 ) 2
d= √ 16 + 16
d= √32
d=5.656854
Answer:
970m^{2}
Step-by-step explanation:
This polygon can be divided in two figures: one is a triangle, an the other one is a square.
We'll begin calculating the triangle's area, using the following formula:
Where:
As you can see, I added both sides of the triangle that measure 9 m and also the lenght of the square that measures 20 m! This added up is what the base of the triangle measures on total.
Now we are going to calculate the square's area, that is much more simple:
Where:
To know the whole figure's area, we add up both areas:
Answer:
320.6
Step-by-step explanation:
<u>Three hundred twenty = 100 * 3 + 10 * 2 = 320</u>
<u>Six tenths: 0.1 * 6 = 0.6</u>
<u />
320 + 0.6
320.6
Answer: 320.6
