Math it's just multiplying and dividing fraction. just 7 & 8
1 answer:
7.
find a common denominator
it will turn into 54 over 45 times -50 over 45
multiply across, leaving the denominator the same
divide the numerator by the denominator
leaving you with 60
ANSWER: 60
8.
Turn the whole number into a fraction by multiplying 3 by 8, also write an 8 under your answer, put the negative in front of the fraction

The answer to the question is (2,-2) d
Answer:
initial velocity = 64 m/s
Step-by-step explanation:
Differentiate H = 64t - 16t² to find an equation for velocity:
Velocity = = 64 - 32t
Initial velocity (u) is when t = 0:
u = 64 - 32(0)
⇒ u = 64 - 0
⇒ u = 64 m/s
