You can't she do the same thing to me like I just be answering question for points and they mostly be correct and she just be deleting the questions like crazy.
The rate of change of the size of the diagonal is; 25.2 ft/s
By Pythagoras theorem;
The length, l of a diagonal of a rectangle whose sides have lengths x and y is;
In essence; the length of the diagonal is dependent on the length, x and y of the sides.
Therefore;
(dl/dt)² = (dx/dt)² + (dy/dt)²
where;
- (dx/dt) = 19 ft/s
- (dy/dt) = -15 ft/s
Therefore,
(dl/dt)² = 19² + (-15)²
(dl/dt)² = 361 + 225
dl/dt = √586
dl/dt = 25.2
Therefore, the size of the diagonal is changing at a rate of; 25.2 ft/s.

Answer:
Yes
Step-by-step explanation:
The first one is 35+15 because 7*5 is 35 and 3*5 is 15
The second one is 45+5 because 9*5=45
35+15=50
45+5=50
Yes, they are equal.
