Answer:t=2.11 hr
Step-by-step explanation:
Given
Aydlett is 2 miles offshore and village is 6 miles down a straight line from the Point on the shore nearest the island
Person can row boat at 2 mph in water and can walk 5 mph in land
Let us suppose Person land the boat at a x miles from Point on the shore
thus time taken by him to reach
Time taken person to reach village by land is
total time
we need the time to be least so differentiate t w.r.t to x
Equating Above term to zero to get minimum time
Substituting x in time equation
The lateral area of a cone is 147ft².
The total surface area of the cylinder is 867ft².
The total surface area is 1014ft²
<h3>What is the lateral surface area of a cone?</h3>
The lateral area of a cone is defined as the area covered by the curved surface of the cone.
Lateral area of a cone = πr x √(r² + h²)
Where:
- r = radius = 12/2 = 6ft
- h = height = 5ft
- π = 3.14
3.14 x 6 x √(36 + 25) = 147ft²
<h3>What is the total surface area of the figure ?</h3>
Total surface area of the cylinder : πr(r + 2h),
(3.14 x 6) x (6 + 40) = 867ft²
Total surface area = 867 + 147= 1014ft²

Answer:
1/5
Step-by-step explanation:
When the dilation is centered at the origin, the dilation factor is applied to each pre-image coordinate to get the image coordinate.
k(10, -15) = (2, -3)
k = 2/10 = -3/-15 = 1/5
The scale factor of the dilation is 1/5.
