-4/15 mile per minute
Answer:
12:28
Step-by-step explanation:
yesterday the ratio would be 6:14 so then you double that to get 12:28
A cube has six sides so i divide 150 by 6 which is 25, so now we know wach side has an area of 25 square inches, square root 25 is 5. now we know each side length is 5 inches
For this case we have an equation of the form:
y = A * (b) ^ t
Where,
A: initial amount
b: decrease factor
t: time
Substituting values:
y = 30 * (b) ^ t
To calculate t we use a point in the table.
We have:
(t, y) = (1, 28.5)
Substituting:
28.5 = 30 * (b) ^ 1
b = 28.5 / 30
b = 0.95
Answer:
a. Decay factor is 0.95
Answer: The boat moved 768.51 feet in that time .
Step-by-step explanation:
Since we have given that
Height of the lighthouse = 1000 feet
Angle depression to boat 'a' = 29°
Angle of depression to shore 'b' = 44°
Consider ΔABC,
Now, Consider, ΔABD,
We need to find the distance that the boat moved in that time i.e. BC
so,
Hence, the boat moved 768.51 feet in that time .
