What we know:
Area=l x w
vertices at (-4,0),(-3,1), (0,-2),(-1,-3)
pythagorean formula=a²+b²=h²
What we need to find:
Area
Finding length:
Length of rectangle is from point (-4,0) to (-1,-3), found it by plotting the points on graph paper. Went down 3 units and right 3 units to go from one point to the other, these are the a and b in the pythagorean formula.
a²+b²=h²
(3)²=(3)²=h²
9+9=h²
18=h²
√18=√h²
√18=h
Finding width:
Width of rectangle is from point (-4,0) to (-3,1), found it by plotting the points on graph paper. Went up 1 unit and right 1 unit to go from one point to the other, these are the a and b in the pythagorean formula.
a²+b²=h²
(1)²+(1)²=h²
1+1=h²
2=h²
√2=√h²
√2=h
Now we can find area,
Area= l x w
= √18 x√2
=√36=6
Area=6
Remember that when we square root a number we get two solutions, one negative and one positive but since length, width and area are positive we only use positive solutions.
If the caterpillar crawled 22cm farther than the ant, then we are adding 53 and 22 to get 75cm.
319049
as 100,042 + 98,117 + 120,890 = 319,049
Answer:
Rounding off we get 3.1%
Step-by-step explanation:
Population in 2000 = 4.2 mil
Population in 2032 ( 32 years later) = 4.2*2= 8.4 mil
Population increase per year:
percentage of population increase:
Answer:
(2.1)
Step-by-step explanation:
assuming your period (.) is actually a comma in the U.S. it would be the coordinate (2,1) where x =2 and y =1.
