Answer:
<u>t ≤ 325</u>
Step-by-step explanation:
the inequality: t+225 ≤ 550
t ≤ 550-225
Subtract 225 from 550
t ≤ 325 :)
3(4x-6)=2y
distribute
12x-18=2y
divide both sides by 2
6x-8=y
y=6x-8
Answer:
![y(x) = e^{3x} [Acos x+Bsin x]](https://tex.z-dn.net/?f=y%28x%29%20%3D%20e%5E%7B3x%7D%20%5BAcos%20x%2BBsin%20x%5D)
Step-by-step explanation:
Given is a differential equation
We have characteristic equation as
The above quadratic cannot be factorised hence use formula
Hence general solution would be
Answer:
Cheetahs can go from 0 to 60 miles per hour in just 3.4 seconds and reach a top speed of 70 miles per hour. While they are the fastest land animal in the world, they can only maintain their speed for only 20 to 30 seconds.
Step-by-step explanation:
The sum of 1.5x and 16.5x is equal 180°.
1.5x + 16.5x = 180
18x = 180 |:18
x = 10
The angles 20y and 16.5x are the vertical angles, therefore:
20y = 16.5x
20y = 16.5(10)
20y = 165 |:20
y = 8.25
<h3>Answer: x = 10 and y = 8.25</h3>
