Answer:
do rise over run from the x coordinate 8/1 positive 4 on the x line
Step-by-step explanation:
Vaya a una pagina que se llama y ponga la equacion donde dice inserte el problema y ahi le va a aparecer la grafica
intente
∂t/∂x = -46x/(8 +x² +y²)²
∂t/∂y = -46y/(8 +x² +y²)²
At (x, y) = (1, 1)
.. ∂t/∂x = -46/100
.. ∂t/∂y = -46/100
The answer is true...
Why?
Let's take (2x) as a simple polynomial. Subtracting 2x from 2x is one thing, then adding it's inverse, (-2x) yields the equation to 0. This is why it is true...
Hope this helps!! Please give me brainliest!
Answer:
1/10 per sec
Step-by-step explanation:
When he's walked x feet in the eastward direction, the angle Θ that the search light makes has tangent
tanΘ = x/18
Taking the derivative with respect to time
sec²Θ dΘ/dt = 1/18 dx/dt.
He's walking at a rate of 18 ft/sec, so dx/dt = 18.
After 3seconds,
Speed = distance/time
18ft/sec =distance/3secs
x = 18 ft/sec (3 sec)
= 54ft. At this moment
tanΘ = 54/18
= 3
sec²Θ = 1 + tan²Θ
1 + 3² = 1+9
= 10
So at this moment
10 dΘ/dt = (1/18ft) 18 ft/sec = 1
10dΘ/dt = 1
dΘ/dt = 1/10 per sec
