Y · y = y²
when multiplying exponents, you add them together
9x^2-16y^2=
(3x+4y)(3x-4y)
Answer:
1.1 meters/second
Step-by-step explanation:
Speed = the magnitude of distance / time
Distance = 9.9 meters
Time = 9.0 seconds
Speed = 9.9 meters / 9.0 seconds = 1.1 meters/second
Answer:
≈ 37.9°
Step-by-step explanation:
Using the tangent ratio
tanΘ = where (x, y ) = (9, 7 )
tanΘ = , thus
Θ = ( ) ≈ 37.9° ( to the nearest tenth )
Divide total distance by total time:
30 feet / 2 seconds = 15 feet per second
Answer: 15 feet per second
