Answer:
-0.69 feet per second
Step-by-step explanation:
We have dx/dt = 2 ft/sec, and we want to determine dy/dt.
x and y are related by the Pythagorean Theorem.
x²+y²=16²
Differentiate both sides of this equation with respect to t to get


Divide both sides by 2y

When x = 5 ft, we have
x²+y²=16²
5²+y²=256
y²=256-25=231
therefore
y= 

=-0.69
The top of the ladder is sliding down (because of the negative sign in the result) at a rate of -0.69 feet per second.
Based on the information given, it has been calculated that they value of x will be 0.9646.

Solving triangles</h3>
Based on the information given, it should be noted that the sine formula will be used.
Therefore, the equation to solve the question will be:
Sin 16° = x/3.5
x = Sin 16° × 3.5
x = 0.2756 × 3.5
x = 0.9646

Answer: 6 Hope this helps, please consider making me Brainliest.
Step-by-step explanation:
Let's plug in the assigned values of x and y:
2(3x - 6) - 5y --> 2(3(-2) - 6) - 5(6) =
2(-6 - 6) - 5(-6) =
2(-12) - (-30) =
-24 + 30 =
