Answer:

m = -6

Step-by-step explanation:

Suppose we have an differential equation in the following format:

ay' + by = 0

The differential equation has the following equivalent polynomial

ar + b = 0.

The root of the polynomial is a value of m so that the function y = e^(my) is a solution of the equations.

In this problem, we have that:

y' + 6y = 0

The polynomial is

r + 6 = 0

r = -6

So the value is m = -6

y=e^{mx}\implies y'=me^{mx}

y'+6y=0\iff me^{mx}+6e^{mx}=(m+6)e^{mx}=0\implies m=-6

So one solution to the ODE is y=e^{-6x}.

A monument in the shape of a right triangle sits on a rectangular pedestarl that is 7 meters high by 16 meters long. The longest
Minchanka [31]

Answer: 70 meters

Step-by-step explanation:

Hi, since the situation forms a right triangle and a rectangle, we have to apply the Pythagorean Theorem (for the triangle)

c^2 = a^2 + b^2  

Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.  

Replacing with the values given:  

65^2 = 16^2 + x^2  

4,225 = 256 + x^2

4,225-256 = x^2

3,969=x^2

√3,969 =x

63=x

We have calculated the missing side of the triangle, now we have to add the height of the rectangle:

63 +7 =70 meters

Feel free to ask for more if needed or if you did not understand something.
