2220000
it just means that 22.2 needs to be multiplied by 10, 5 times, so just move the decimal five to the right.
Answer:
Perimeter = 19.6 cm
Area = 9.3 cm squared
Step-by-step explanation:
Perimeter: Add sides: 3.1 + 9.3 + 7.2 = 19.6
Area: 9.3 x 2 x 1/2 = 9.3
B: 2 and 1/6.
Tricky one if you rush through, its meant to SEEM complicated, like a lot of math questions.
1) Considering that those points (2,k) and (k,32) determines one same line, within the plane. Therefore we can say that
2) Considering that since they pass through the origin then their x -coordinate is equal to zero, and their y coordinate as well so
3) We can state that as a matter of fact (2, k) and (K, 32) can be rewritten as (2,0) and (0,32)
k=0
<span>(x-h)^2 + (y-k)^2 = r^2
(h, k) = (-5, -1)
r = 5
</span><span>(x+5)^2 + (y+1)^2 = 5^2
</span><span>(x+5)^2 + (y+1)^2 = 25</span>
