Answer:
–90° and 630°
Step-by-step explanation:
The described angle will be -90° plus any integer multiple of 360°. Possible values for the angle are ...
-90° and 630°
_____
Angles are conventionally measured counterclockwise from the positive x-axis. The angle shown in the attachment is measured clockwise, so represents a <em>negative</em> 90° angle.
The perimeter is the total measurement of all the sides together.
P = 82
Perimeter is side + side + side and so on.
So here is what we have.
15.4 + 16.2 + 28.7 + d = 82
Add up what you have now
60.3 + d = 82
Subtract 60.3 from both sides to get D
d = 82 - 60.3
d = 21.7
2.4 is the right answer my guy
Lets suppose k is the constant of proportionality.
z = k * x / y
when x is 16 and y is 17, z has the value 11.294117647059
11.294117647059 = k * 16/17
Multiplying 17 on both sides
11.294117647059 * 17 = k * 16
192 = k * 16
Dividing 16 on both sides
192/16 = k
k = 12
Now when x= 22, and y= 26
z = k * x/y
z = 12 * 22 / 26
z = 10.1538461538 : Answer
Hope it will help :)
Answer:
Step-by-step explanation:
The given equation 5y'' + 3y' - 2y =0 can be written as
Solving for complementary function we have Roots of 
as follows
Thus the complementary function becomes
y=
where
are calculated roots
thus solution becomes
Now to solve for the coefficients we use the given boundary conditions
hence the solution becomes
