Answer:
Option C
Step-by-step explanation:
From the question we are told that
Co-ordinate of school A =(7,12)
Co-ordinate of school B =(-21,-13)
Generally the sum of the vector is mathematically represented
![(A+B)=(-21-7,-13-12)](https://tex.z-dn.net/?f=%28A%2BB%29%3D%28-21-7%2C-13-12%29)
![(A+B)=(-28,-25)](https://tex.z-dn.net/?f=%28A%2BB%29%3D%28-28%2C-25%29)
Generally the actual distance between the schools is mathematically given as
![d=\sqrt{-28^2+-25^2}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B-28%5E2%2B-25%5E2%7D)
![d=\sqrt{1409}](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B1409%7D)
![d=37.5366 \approx 37.537m](https://tex.z-dn.net/?f=d%3D37.5366%20%5Capprox%2037.537m)
Answer:
- 15 2/9
Step-by-step explanation:
3⁻² = 1 / 3² = 1/9
(½)⁻⁴ = 1 / (½)⁴ = 1 / (1/16) = 16
³√(8/27) = ³√8 / ³√27 = 2/3
1/9 - 16 + 2/3 = 1/9 - 144/9 + 6/9 = - 137/9 = - 15 2/9
A trapezoid is a quadrilateral with one pair of opposite sides parallel. It can have right angles (a right trapezoid), and it can have congruent sides (isosceles), but those are not required.
I think the answer is $440. 5% is $10 1% is $2 = $12 x 2 = $24
$24 x 10 = $240
200+240=440
