- Get the prime factors of -16
- 16 2
- 8 2
- 4 2
- 2 2
1
16 = 2⁴
- Express the -16 as a power
![\sqrt[4]{-2^{4}} or \sqrt[4]{2^{4}i^{2}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B-2%5E%7B4%7D%7D%20%20or%20%20%20%5Csqrt%5B4%5D%7B2%5E%7B4%7Di%5E%7B2%7D%7D)
Remember that -1 = i²
- Get the fourth root of -16

Step-by-step explanation:
Answer:
distance of diver 1 from the shark ≈ 18.88 m
Step-by-step explanation:
The illustration forms a triangle. The base of the triangle which is their distance apart is given as 30 m . The known angle of the triangle are 52° and 39°. To find the unknown side we subtract the sum of 52° and 39° from 180°. Note that the total angle in a triangle is 180°.
Therefore,
180 - (52 + 39) = 180 - 91 = 89
°. Now the three angle of the triangles are 52°, 39° and 89°.
Using the law of sine we can find the distance of the diver 1 from the shark.
let a = distance of the first diver to the shark.
a/sin 39° = 30/sin 89°
cross multiply
a sin 89° = 30 sin 39°
divide both sides by sin 89°
a = 30 sin 39°/sin 89°
a = 30 × 0.62932039105
/sin 89°
a = 18.8796117315
/0.99984769515
a = 18.8824876258
a ≈ 18.88 m
Answer:
28 and 29
Step-by-step explanation:
the equation is x÷7≤4
26÷7= 3.7 ≠ x÷7≤4
27÷7= 3.8 ≠ x÷7≤4
28÷7=4
29÷7= 4.14=x÷7≤4
