Answer:

  60 m

Step-by-step explanation:

The difference in height is the short leg of a right triangle with long leg 35 m and hypotenuse 37 m.

  (∆h)² + 35² = 37² . . . . . . . . . . the Pythagorean theorem

  (∆h)² = 1369 -1225 = 144

  ∆h = √144 = 12 . . . meters

The taller building is 48 m + 12 m = 60 m high.

My professor showed us in class today how to use ode45 to solve a differential equation numerically. i would like to use it on m
Brilliant_brown [7]

Yes, ode45 can be used for higher-order differential equations. You need to convert the higher order equation to a system of first-order equations, then use ode45 on that system.

For example, if you have

... u'' + a·u' + b·u = f

you can define u1 = u, u2 = u' and now you have the system

... (u2)' + a·u2 + b·u1 = f

... (u1)' = u2

Rearranging, this is

... (u1)' = u2

... (u2)' = f - a·u2 - b·u1

ode45 is used to solve each of these. Now, you have a vector (u1, u2) instead of a scalar variable (u). A web search regarding using ode45 on higher-order differential equations can provide additional illumination, including specific examples.

Fone the slope of a line that is perpendicular x = -12
Vinvika [58]

Answer:

m [slope] = 1/12

Step-by-step explanation:

If a line is perpendicular (90 degrees, forms a right angle) to another, the slope of the line must be an opposite reciprocal of the other. The opposite reciprocal of m is -1/m.

An opposite reciprocal is created by flipping the numerator and denominator, and making it negative.

Therefore, if m is -12 it's opposite reciprocal is -1/-12 = <u>1/12</u>.
