Jay and Pete are running in a race. At 9am Jay was 15 ft ahead of Pete, at 10am Pete was ‘f' ft ahead of Jay. Write an expressio
Burka [1]

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

Which simplifications of the powers of i are correct?
OleMash [197]

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

i^2=-1\\i^3=-i\\i^4=1

We can use the smaller powers of i to solve the larger powers.

a. i^27=−i

i^{27}\\={i^{24}}.i^3\\={i^{4*6}}.-i\\=(i^4)^6.-i\ \ \ \ As\ we\ know\ i^4=1\\=(1)^6.-i\\=1*-i\\=-i

b. i^28=i

i^{28}\\=i^{4*7}\\=(i^4)^7\\=(1)^7\\=1

c. i^14=1

i^{14}\\=i^{12}.i^2\\=(i^{4*3}).i^2\\=> i^2=-1\\=(i^4)^3.-1\\=(1)^3*-1\\=-1

d. i^8=1

i^8\\=i^{4*2}\\=(i^4)^2\\=(1)^2\\=1

e. i^5=i

i^5\\=i^{2*2*1}\\=i^2*i^2*i\\=(-1)(-1)(i)\\=i

Hence,

The correct simplifications of powers of i are:

a. i^27=−i

d. i^8=1

e. i^5=i
