1.539 ÷100 would be the same
Answer:
-8
Step-by-step explanation:
x^(m/n)=![\sqrt[n]{x}^m](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Bx%7D%5Em)
(-32)^(3/5)
=![\sqrt[5]{(-32)} ^3](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B%28-32%29%7D%20%5E3)
=(-2)^3
=-8
Answer:
9 years
the tree doubles in height
we can make a model
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1024
Let's say 1024 is the maximum height
half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year

Step-by-step explanation:
I think its correct
Answer:
1548.66 feet
Step-by-step explanation:
We can draw a straight line down the middle to form two right triangles
This will split the 70 degree angle into two 35 degree angles
We now have two 90-35-55 right triangles
Now we can use cos(55) * the hypotenuse on both sides to get the distance across the lake
Thus we have:
1200cos(55 = 688.29
1500cos(55 = 860.36
Best of luck
