Answer:
None of these (see below).
Step-by-step explanation:
y = m cos pt - n sin pt
Using the chain rule:
dy/dt = m * -sin pt * p - ( n * cos pt * p)
= -mp sin pt - np cos pt.
dy/dt^2 = -mp * -cos pt * p - (np * - sin pt * p)
= mp^2 cos pt + np^2 in pt.
Total $129
129 - 24 = 105
105 / 3 = 35

Answer:
Mandy will take 67.5 mins to complete the 15 km race.
Step-by-step explanation:
Given:
Mandy runs 4 km in 18 min
She plans to run in a 15 km race.
We need to find how much time required to run 15 km.
4 km =18 min
15 km = time required for 15 km race
By Using Unitary method we get,
Time required for 15 km = 
Hence time required by Mandy to complete 15 km race is 67.5 mins.
