Answer:
-26
Step-by-step explanation:
2 × 3 + 4 − 6^2
PEMDAS
exponents are first in this equation
2 × 3 + 4 − 36
Then multiply
6 +4 -36
Then add and subtract from left to right
10-36
-26
The change in kinetic energy of the system is 200 J
Kinetic energy is the energy that an object possesses as a result of its motion.
It is given by:
Kinetic energy = (1/2)m[v - u]²
Where m is the mass of the object, v is the final velocity and u is the initial velocity.
Given that m = 16 kg, v = 20 m/s, u = 25 m/s, hence:
Kinetic energy = (1/2) * 16 * (20 - 25)² = 200 J
The change in kinetic energy of the system is 200 J

1) is false, it is always a rhombus.
2) is true, a rectangle with all sides equal would be a square.
3) is false, a kite's side lengths must be 2 pairs of unequal lengths.
4) is true, a square is a rhombus that has 90-degree angles.
5) is true, a kite must have 2 pairs of unequal lengths, but a trapezoid cannot have exactly 2 sides of equal lengths.
The original price was $70.2. (If it’s not supposed to have cents then it’s just $70).
This is because you convert 35% to 1.35. Then, you multiply 52 by 1.35. That’ll give you 70.2.
P(A)=0.2
P(B)=0.3
P(A and B)= 0.2 x 0.3=0.06
