An exponent is a number that is used to multiply the base number by itself. If your number is 4 to the power of two you need to multiply four by four to get sixteen
Answer:
Step-by-step explanation:
Given
Balloon in the east makes an angle of elevation of
and is at height of 461 m
Balloon in the west makes an angle of elevation of
and is at height of 296 m
Erica height is 1.6 m tall so net altitude of Red balloon is 459.4 m
and net height of Blue balloon is 294.4 m
using trigonometry
![\tan 36=\frac{459.4}{d_1}](https://tex.z-dn.net/?f=%5Ctan%2036%3D%5Cfrac%7B459.4%7D%7Bd_1%7D)
![\tan 51=\frac{294.4}{d_2}](https://tex.z-dn.net/?f=%5Ctan%2051%3D%5Cfrac%7B294.4%7D%7Bd_2%7D)
![d_1=632.30 m](https://tex.z-dn.net/?f=d_1%3D632.30%20m)
![d_2=238.4 m](https://tex.z-dn.net/?f=d_2%3D238.4%20m)
Distance between two Balloons
![d=d_1+d_2](https://tex.z-dn.net/?f=d%3Dd_1%2Bd_2)
![d=870.70 m](https://tex.z-dn.net/?f=d%3D870.70%20m)
The correct answer is A. The commutative property says that we can swap number when we add. More exactly... it means that a+b=b+a => -13+27=27+(-13)= 14
Answer:
sqrt 256 is a rational number, so that one is not an irrational number.
Answer:
