No real zeros.

Step-by-step explanation:

Given... y = What are all the real zeros of y=(x-20)^2 +5, №18010167, 15.05.2021 02:49

Since above equation has no real real value, there are no zeros.

But complex zeros are:

No real zeros for the function.

Explanation:

zero of a function f, if f(r) = 0

solve:

\sf y=(x-20)^2 +5

so when f(y) = 0

\hookrightarrow \sf (x-20)^2 +5 = 0

\hookrightarrow \sf (x-20)^2  = -5

\hookrightarrow \sf (x-20)  = \sqrt{-5}

\hookrightarrow \sf x  = \pm \sqrt{-5} +20

\hookrightarrow \sf x  = \sqrt{-5} +20, \ \sf x  = -\sqrt{-5} +20

check:

\hookrightarrow f \sf (\sqrt{-5} +20) = Not \ applicable, f \sf (-\sqrt{-5} +20) = Not \ applicable

SI=(P*R*T)/100

P=2000

R=1.5

T=6

SI=(2000*1.5*6)/100

=(2000*9)/100

=180

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5

Speed=Distance/time

Here,

distance=15m

time=1sec

speed=15/1=15m/sec

Distance=Speed*time

time=15min=15*60sec=900sec

Distance travelled in 15 min=15*900=13,500m

=13500/1000 km=13.5Km
