Answer:
(15 + f) feets
Step-by-step explanation:
Given that:
Race between Jay and Pete:
Let ;
distance covered by Jay = j
Distance covered by Pete = p
At 9:00a.m :
Jay was 15 feet ahead of Pete
Hence,
j - p = 15 feet
At 10 a.m :
Pete was 'f' feet ahead of Jay:
p - j= f feets
Number of feets Pete ran than Jay between 9 to 10 a. M
f feets + number of feets at which Pete was being Jay at 9a.m
f feets + 15 feets = (15 + f) feets
Answer:the percent change in the puppy's weight= 275%
Step-by-step explanation:
Jillian's puppy Weight at 2 months =16 pounds
Jillian's puppy Weight at 8 months =60 pounds
percent change in the puppy's weight= change in weight / Old weight x 100
(60 pounds -16pounds ) / 16 x 100
44/16 x 100 = 275%
The correct simplifications of powers of i are:
a. i^27=−i
d. i^8=1
e. i^5=i
Step-by-step explanation:
We know that
We can use the smaller powers of i to solve the larger powers.
a. i^27=−i
b. i^28=i
c. i^14=1
d. i^8=1
e. i^5=i
Hence,
The correct simplifications of powers of i are:
a. i^27=−i
d. i^8=1
e. i^5=i
