2(−0.45)5=9.2
Step-by-step explanation:
=23.45
What is unit price?- unit price is the cost of one item(which in this case is an apple)
5 apples- $1.30
1 apple- 1.30 / 5
= $0.26
Answer:
3695.5 m
1530.73 m
Step-by-step explanation:
Given in the question,
The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m
We will use trigonometry identities
<h3>sinФ = opposite / hypotenuse</h3><h3>cosФ = adjacent/ hypotenuse</h3>
1)
distance of probe from top of sea to surface = x
cos(90 - 67.5) = x / 4000
x = 3695.5 m
2)
horizontal distance from ship to probe = y
sin(90-67.5) = y / 4000
y = 1530.73 m
