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 .
Answer:
19
Step-by-step explanation:
6 times 2 = the years between the youngest and oldest. 6 times 2 =12. 7+12=19
Make y = mx = b
y = -x - 1
Slope is -1
Perpendicular = opposite sign and reciprocal slope
1/1 = 1, slope would be 1
Solution: slope = 1
X=10 y=5 would be the answers I'm not sure on the equation
The answer would be 1, prime numbers can only be evenly divided by one or itself also positive divisors can only be one or itself.
