if the length of the drawbridge, r, is 20 meters and the point p is 16 meters above the roadway , what is the distance d?
zhenek [66]
I'm assuming that the figure formed in this problem is a right angle. Thus, we need to use the Pythagorean theorem to get the distance or the hypotenuse.

Length = 20 meters
Height = 16 meters

a² + b² = c²

(20m)² + (16m)² = c²
400m² + 256m² = c²
656m² = c²
√656m² = √c²
25.61 m = c

The distance is 25.61 meters.

Differentiate with respect to x:y= sinh^-1(x^2+1)
Aleks [24]

Answer:

The first derivative of y = \sinh^{-1} (x^{2}+1) is y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}.

Step-by-step explanation:

We proceed to find the first derivative of y = \sinh^{-1} (x^{2}+1) by explicit differentiation and rule of chain:

y = \sinh^{-1} (x^{2}+1)

y' = \frac{2\cdot x}{\sqrt{(x^{2}+1)^{2}+1}}

y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}

The first derivative of y = \sinh^{-1} (x^{2}+1) is y' = \frac{2\cdot x}{\sqrt{x^{2}+2\cdot x +2}}.

What is the simplified form of this expression? (2x + 9) + (11x − 4)
timama [110]
The simplified form is 13x+5

You first add 2x and 11x, where you will get 13x, and from there, you subtract 4 from 9, where you will get 5, resulting in the answer of 13x+5.

Hope this helps :)
