Step-by-step explanation:
uhhhhhhhhhhhhhhhhhh trust me
Answer:
B)313 ft
Step-by-step explanation:
Hello,I think I can help you with this
to solve this you need to find all the measures of the rigth triangle formed by Hailey, the boat, and the point on the surface of the sea just above the head of Hailey
Step 1
define
triangle
Hypotenuse=300 feet
opposite side=y
adjacent side=x
angle of depression =30°
Step 2
find the distances

so, the point on the surface of the sea just above hailey is 259.8076 ft from the boat

hailey is at a depth of 150 feet
Step 3
now,her partner is 25 feet directly below her,it is
partner's depth is =hailey is at a depth of 150 feet+25
Y=175
he is at the same distance from de boat ( horizontal),because it is the same point in the sea surface.
X=259.80
Step 4
to find the distance between the partner and the boat we can use
Pythagoras theorem
![adjacentside^{2} +opposite side^{2} =hypotenuse^{2} \\\sqrt[2]{adjacentside^{2} +opposite side^{2}} =Hypotenuse\\Hypotenuse=\sqrt[2]{175^{2} +259.8076^{2}} \\\\Hypotenuse=313.24 ft](https://tex.z-dn.net/?f=adjacentside%5E%7B2%7D%20%2Bopposite%20side%5E%7B2%7D%20%3Dhypotenuse%5E%7B2%7D%20%5C%5C%5Csqrt%5B2%5D%7Badjacentside%5E%7B2%7D%20%2Bopposite%20side%5E%7B2%7D%7D%20%3DHypotenuse%5C%5CHypotenuse%3D%5Csqrt%5B2%5D%7B175%5E%7B2%7D%20%2B259.8076%5E%7B2%7D%7D%20%5C%5C%5C%5CHypotenuse%3D313.24%20ft)
so, Hailey's diving partner is 313 ft away from the boat(B)
Have a great day.
Answer:
so u multiply negative four times nagative 1.5
The correct answer is b because of the answers given you start to graph it gives you the answer.
Answer:
C. 81π cm³
Step-by-step explanation:
The volume of the cylinder is found using the volume formula:
V = πr²h
where r is the radius and h is the height.
__
<h3>application</h3>
For the cylinder shown, the radius is r = 3 cm, and the height is h = 9 cm. Then the volume is ...
V = πr²h = π(3 cm)²(9 cm) = 81π cm³ . . . . matches choice C
