Answer:
A
Step-by-step explanation:
Length :
Perimeter:
Perimeter = 2(Length + Width)
15x + 17y = 2( + Width)
15x + 17y = 7x + 14y + 2(Width)
15x + 17y -7x -14y = 2(Width)
8x + 3y = 2(Width)
Width =
Width = 4x + 3y/2
Answer:
m∡A = 41.4°
m∡B = 48.6°
m∡C = 90°
a = 3
b = 9
c = 12
Step-by-step explanation:
to find the length of side 'a' I used the Pythagorean Theorem to get:
a² + 9² = 12²
a² + 81 = 144
a² = 63
a = which equals
which is 3
to find m∡B I found the arcsin(B) = 9/12 to get 48.6
to find m∡A I subtracted the sum of 90 + 48.6 from 180°
Answer:
73.77 ft/s
Step-by-step explanation:
Let's imagine this situation as a right triangle where the distance between the two points is the hypotenuse.
-Applying Pythagoras theorem:
#Take the derivative of the first equation and solve for :
#We then substitute the values given in the question to solve for :
Hence, the rate of change of the distance between the motorcycle and the balloon 7 seconds later is 73.77 ft/s
