<span>y'' + 2y' + 17y = 0 </span>
<span>y(0) = 1 y'(0) = -1 </span>
Simplify 1st equation
2x-y=-2
simplify second equation
-x+y=5
add both equations
2x-y=-2
-x+y=5
------------
x =3
-x+y=5
-3+y=5
y=8
x=3, y=8
Answer:
See explanation below
Step-by-step explanation:
Given the ratio between two groups to be 3:7
Total ratio = 3+7 = 10
Total sweet shared = 30sweets
For the group with ratio of 3;
Share = 3/10×30
Share = 3×3
Share = 9 sweet
For the group with ratio of 5
This share = 7/10×30
This share = 7×3
This share = 21sweet
Answer:
F=26.555≈27 degrees
Step-by-step explanation:
sin F = opposite/hypotenuse = 3.8/8.5
sin F = 3.8/8.5
F = sin^-1(3.8/8.5)
(3.8 is opposite of angle F, 8.5 is hypotenuse)
