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.
the corresponding point on the graph of where
is
.
<u>Step-by-step explanation:</u>
We have , The point (-12,12) is on the graph of y=f(x). We need to Find the corresponding point on the graph of y=g(x) where g(x)= 1/3f(x) . Let's find out:
On function , a point
lies . Another function
.
According to question , as On function , a point
lies :
⇒
Now, Putting x = -12 in function we get:
⇒
⇒ {
}
⇒
⇒
Therefore, the corresponding point on the graph of where
is
.
