Answer:
The 13.2 meters from that point on the ocean floor to the wreck.
Step-by-step explanation:
As given
A ship's sonar finds that the angle of depression to a ship wrack on the bottom of the ocean is 12.5°.
If a point on the ocean floor is 60 meters.
Now by using the trigonometric identity.
As shown in the figure given below.
Perpendicular = CB
Base = AC = 60 meters
Put in the identity
CB = 60 × 0.22
CB = 13.2 meters
Therefore the 13.2 meters from that point on the ocean floor to the wreck.
If x=0 then they have same value
1st and 2nd options are out
for x=-1
g(-1)=1
h(-1)=-1
3rd is true
4th
false
for all values except zero, g(x)>h(x)
correct ones are
g(x) > h(x) for x = -1.
For positive values of x, g(x) > h(x).
For negative values of x, g(x) > h(x).
Given that the angle of incidence is equal to the angle of reflection, we can state tha the angle formed by the eyes of Jason with the mirror is equal to the angle formeb by the top of the three with the same mirror.
Then, you can write this similarity equation:
[height of the eyes of Jason] / [distance from the poistion of Jason to the image on the mirror] = [height of the tree / distance from the mirror to the base of the tree]
6feet / 8feet = x/40feet
x = 40feet *[6/8] = 30 feet.
Answer: 30 feet.
Answer:
1.2m
Step-by-step explanation:
You must first find out how much the daffodil grew over the 8 days:
0.05 x 8 = 0.4
Then you must add how much it grew to the original height:
0.4 + 0.8 = 1.2
Hope this helps you out! : )
Answer is r32 because it is the square root of an exponent you must divide it.
