A cat is stuck in a tree. A firefighters 15-foot ladder is the leaning against a tree. The ladder and the ground form a 62° angl

artcher [175]

To solve this problem you must apply the proccedure shown below:

1. You have:

Sinα=opposite/hypotenuse

α=62°
opposite=x
hypotenuse=15 ft

2. When you substitute the values into Sinα=opposite/hypotenuse, you obtain:

Sinα=opposite/hypotenuse
Sin(62°)=x/15

3. You must clear "x", as below:

x=(15)(Sin(62°))
x=13.24 ft

The answer is. 13.24 ft

Find dy/dx and d2y/dx2, and find the slope and concavity (if possible) at the given value of the parameter. (If an answer does n

ella [17]

Answer:

The slope of the function is ²/₃ and since the second derivative is zero, the concavity doesn't exist.

Step-by-step explanation:

Given;

x = 6t

y = 4t - 3

point t = 4

$\frac{dy}{dx} = (\frac{dy}{dt} )/(\frac{dx}{dt} )=\frac{\frac{dy}{dt} }{\frac{dx}{dt}} \\\\\frac{dy}{dt} = 4; \frac{dx}{dt} = 6\\\\\frac{dy}{dx} =\frac{4}{6} = \frac{2}{3}$

The slope of the function is ²/₃

take the second derivative of the function;

the second derivative will be zero since the first derivative is a constant value.

$\frac{d^2y}{dx^2} = 0$

Since the second derivative is zero, the concavity doesn't exist.
