The distance between the points A to B is 899.9 feet. After rounding off the nearest integer we get 900 feet as the final answer.
Given we know that CD is perpendicular to AD.
The distance between CD is 139 feet.
As from points A the boat's crew measure the angle of elevation to the beacon as 6°
therefore, m∠A = 6°
Another time the angle of elevation is measured from point B which is 19°.
therefore, m∠DBC = 19°
tan 19° = CD/BD
BD = CD/tan19°
BD = 136/tan 19°
now for tan 6° = CD/AD (tangent is opposite over adjacent)
AD = CD/tan 6°
AD = 136/tan 6°
AB = AD ₋ BD
AB = 136/tan 6° ₋ 136/tan 19°
AB = 1295.2 ₋ 395.3
AB = 900 feet
hence the distance from point A to B is 900 feet.

Answer:
gof(x) = x²+8x+15
Step-by-step explanation:
gof(x) = g(f(x))
f(x) = x + 4 and g(x)=x²-1
Substituting
gof(x) = g(f(x)) = g(x + 4) = (x+4)²-1
gof(x) = x²+8x+16 -1 = x²+8x+15
That is if f(x) = x + 4 and g(x)=x²-1, gof(x) = x²+8x+15

Answer:
5.4 yards of fabric can be used to make one dress.
Step-by-step explanation:
We are given the following in the question:
Amount of fabric available = 27 yards
Number of dresses to be made = 5
Amount of fabric required make each dress =
Thus, 5.4 yards of fabric can be used to make one dress.
The answer lies between the whole number 5 and 6.
