Answer:
26.230 Inches per second.
Step-by-step explanation:
Since, Area of square is decreasing at the rate of 43 square inches per second And area is directly proportional to square of the side , So
Its side will be decreasing at the rate of inches per second .
Now,
Perimeter of square is directly proportional to 4 times of the side of the square.
so Perimeter of square will be decreasing at the rate of 4×
After rounding off to three decimal places we will get 26.230 Inches per second.
First option is correct.
Since we have given that
JKL is a right triangle.
Length of JK = 12
Length of KL = 5
By Pythagoras theorem, we get that
So, cos (L) would be
cos(L)=base/hypotenuse
cos(L)=5/13
Hence, First option is correct.
