Answer:
a) 300 miles
b) 2pm}
That is all I can help you :(
Step-by-step explanation:
8am + 6hrs =14hrs =2pm
Multiply the original DE by xy:
xy2(1+x2y4+1−−−−−−−√)dx+2x2ydy=0(1)
Let v=xy2, so that dv=y2dx+2xydy. Then (1) becomes
x(y2dx+2xydy)+xy2x2y4+1−−−−−−−√dxxdv+vv2+1−−−−−√dx=0=0
This final equation is easily recognized as separable:
dxxln|x|+CKxvKx2y2−1K2x4y4−2Kx2y2y2=−dvvv2+1−−−−−√=ln∣∣∣v2+1−−−−−√+1v∣∣∣=v2+1−−−−−√+1=x2y4+1−−−−−−−√=x2y4=2KK2x2−1integrate both sides
Answer:
4
Step-by-step explanation:
4X7 =28
4X2 =8
28-8 =20/5
=4
Is that supposed to be : y = -x^3 ??
<span>i have the same question </span>
<span>yes it is </span>
<span>so when you write x2 you mean x^2 and 2x is 2^x also ? </span>
<span>is it an exponent
sorry, need ponts

Answer:
Example
Step-by-step explanation:
1 Determine if the value 3 is a solution of the equation .Notice in the equation 3x + 3 = x + 13, the solution 5 is not evident by . 2x-2x + 9 = 3x- 9-2x+ 9. 9 = x. from which the solution 9 is obvious. If we wish, we .
