Answer:
y = (1/2)x + 0
Step-by-step explanation:
The equation would be y = mx + b
m is the slope and b is the y-intercept
The speed is 630mp/s I think. Because you have to multiply Wavelength by Frequency to get true speed
Answer:
Step-by-step explanation:

Answer:
1. ft 2. yards 3. units.
Step-by-step explanation:
Pythagorean's Theorem
A and b are both side lengths, c is the hypotenuse.
7^2 + 5^2 = 74
sqrt(74) is the answer for 1.
30^2 - 5^2 = 875
Simplify the radical. sqrt(875) --> 5sqrt(35). The answer for three.
There's a rule in geometry that says a diagonal of a square is the same length as taking a side length times the square root of two. There's your answer for two.
