One way to do this is to notice
Then
We have
and since 
has a period of 
,
and so
A. let the distance be d
so we have Δd/Δt=8.8min
Δd= 8.8Δt
d=∫8.8Δt-------(1)
b. d should be positive because the diver is ascending at a positive rate relative to depth
c. d=rt
t=d/r = 32.12/8.8 min
t= 3.65min
Answer:
20/4.6 or 4.35
Step-by-step explanation:
unit cost is 20/4.6 which rounds to 4.35
Answer:
69°, 69°, and 42°
Step-by-step explanation:
Isosceles triangles have three angles -- one vertex angle and two base angles.
The <u>base angles have the same measure</u> and the vertex angle has a different measure.
<u>Remember all triangles' interior angles sum to 180°.</u>
If the vertex angle is 42°, then the two base angles combined are:
180° - 42° = 138°
Since the base angles are the same, <u>each base angle is:</u>
138° ÷ 2 = 69°
Therefore the angles in the triangle measure 69°, 69°, and 42°.
Answer:
8
Step-by-step explanation:
Step 1: Set up equation
-1 = 7 - x
Step 2: Subtract 7 on both sides
-8 = -x
Step 3: Divide both sides by -1
x = 8
So 7 subtracted by 8 equals -1.
