15 -differences between gymnosperms and angiosperms:
- In gymnosperms ovules are exposed but in angiosperm ovules are enclosed in ovary.
- In angiosperm seeds are enclosed inside the fruits but in gymnosperm seeds are not enclosed inside the fruits.
- Gymnosperm bear cones instead of flowers but angiosperm bear well developed flowers.
16-
- They have mammary glands.
- Their body is covered with hai.
- Breathing takes place through lungs.
17- Uniform acceleration is a change of equal velocity in equal interval of tine.
Non- Uniform acceleration is a change of unequal velocity in equal interval of time.
18- Three equation of motion:
- v =u+at
- s=ut+1/2at^2
- v^2 = u^2+ 2as

Since
∠CPD = x
and segment PN is the angle bisector of this angle, therefore segment PN
equally divides ∠CPD into two angles. Which means that:
∠CPN = ∠NPD = x / 2
Further,
segment PN is also the perpendicular bisector of AB which further means that
the intersection formed by PN and AB creates a right angle (90°). Therefore:
∠NPD + ∠DPB = 90°
x/2
+ ∠DPB =
90°
∠DPB =
90 – x/2
Therefore:
sin∠<span>DPB = sin(90 – x/2) which is not in the choices</span>
However we know that the
relationship of sin and cos is:
sin(π/2
- θ) = cos θ
Where,
π/2
= 90
θ =
x/2
Therefore:
sin(90 – x/2) = cos(x/2)

Answer:
interest: $60
Payment: $360
Step-by-step explanation:
I = Prt
Interest for four years = 300 * 0.05 * 4 = 60
P = P₁ + I = 300 + 60 = 360
Answer: 32
Step-by-step explanation:
Answer:
Though no attachment is included, I believe the answer would be point V.
Step-by-step explanation:
The reason for this belief is because V is the only variable commonly used in both planes. Which would mean V is the point of intersection, since they are the exact same spot.
