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:
h(n) = - 5.3![(-11)^{n-1}](https://tex.z-dn.net/?f=%28-11%29%5E%7Bn-1%7D)
Step-by-step explanation:
This is a geometric sequence with n th term
h(n) = h(1) ![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
where h(1) is the first term and r the common ratio
Here h(1) = - 5.3 and r = - 11, thus
h(n) = - 5.3
← explicit formula

Answer:
2.5(x)+6=3.25(x)+3 4=x. Real world problem below
Step-by-step explanation:
Nico is organizing a party. Going skating, admission is 6 dollars, and each person pays 2.5 dollars for a pair of skates. If he has 3 other people in his group, the equation is 2.5(4)+6=24. He is also looking at going to a trampoline park. It is 3 dollars to get in, and 3.25 per person for an hour on the trampolines. This equation can be shown as 3.25(4)+3 which equals 24.
