Answer:
Step-by-step explanation:
Given differential equation,
Characteristic equation is given by
.
Differential equation have repeated roots and solution of differential equation is .............................(1)
Initial conditions are
Plugging first condition in equation (1),
Equation (1) becomes
............................(2)
differentiate equation (2) with respect to 'x',
Plugging second condition,
Hence,
Answer:
<h2>5s 4 X 2</h2>
Step-by-step explanation:
Answer:
0.1, 1/2, 0 .7 , 3/4
Step-by-step explanation:
3/4, 0.7, 1/2 , 0.1
Change the numbers to the same form
3/4 = .75 1/2 = .5
.75 , .7 , .5 , .1
We want the numbers from least to greatest or smallest to biggest
.1 is the smallest
then .5
then .7
then .75
Changing the numbers back to the original form
0.1, 1/2, 0 .7 , 3/4
Answer:
a) 9r=63
b) 14 mi/h
Step-by-step explanation:
Let say r the speed of the slower cyclist,
2*r the speed of the faster cyclist,
they meet 3 hours later:
a)
<u> (r+2*r)*3=63 </u>
3r*3=63
9r=63
r= 63/9
r=7 (mi/h)
b)
<u>2r=14 (mi/h)</u>
