Step-by-step explanation:
Horizontal it is 4
Vertical it is 2
Use of Pythagoras theorem to find AB
AB= root of 4^2 + 2^2
= 4.47
Answer:

8 )
Step-by-step explanation:
7 ) 8)
In Δ ABC In Δ XYZ
∠ C = 45° ∠ X = 60°
∠ A = 90° ∠ Y = 90°
To Find :
x = ?
y = ?
Solution:
We Know
In Δ ABC
∠ C = 45°
∠ A = 90°
∴ ∠ B = 45° ......Angle sum property of a triangle i.e 180°
∴ Δ ABC is an Isosceles Triangle
∴ AC = AB = x =
Now appplying Trignometry identity we get
Now In Δ XYZ
∠ X = 60°
∠ Y = 90°
∴∠ Z = 30° . .....Angle sum property of a triangle i.e 180°
Now appplying Trignometry identity we get
Now,
Let
. Then
and
are two fundamental, linearly independent solution that satisfy
Note that
, so that
. Adding
doesn't change this, since
.
So if we suppose
then substituting
would give
To make sure everything cancels out, multiply the second degree term by
, so that
Then if
, we get
as desired. So one possible ODE would be
(See "Euler-Cauchy equation" for more info)
X < -1
rearrange➡ 5 + 6 × (x + 4) - (20) < 0
➡ ( 5 + 5 × ( x + 4 )) - 20 < 0
Pull out all of the like terms (factors) ➡ 5x + 5 = 5 ( x + 1)
5 × ( x + 1 ) < 0
divide botg sides by 5
Solve, basic inequality
Subtract 1 frok basic sides
x < -1
Answer:
0
Step-by-step explanation:
Since
1
is constant with respect to
A
, the derivative of
1
with respect to
A
is
0
