Answer:
C) 65°
Step-by-step explanation:
The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(?) = 25/59
? = arccos(25/59) ≈ 64.93°
The indicated angle is about 65°.
_____
You can see that the figure is drawn approximately to scale and that the angle is more than 45°. (The unmarked leg is longer than the given leg.) The only answer choice that is more than 45° is the one shown above.
Answer:
√(-2)²+12+14=√16+14=4+14=18
Step-by-step explanation:
Yes you can. If a vertical line passes trough a line more than once in a graph, then it is inverse but if it passes trough only once it is a function
Answers:
Kinetic Energy Formula: 
Potential Energy Formula: 
Explanations:
For KE:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
For PE:
In the above equation, m represents the mass of the object, h represents the height of the object and g represents the gravitational field strength (9.8 N/kg on Earth) - sometimes referred to as the acceleration of gravity.
