To find the answer, we plug 8 into the equation in the place of x, since x represents the number of minutes.
w(8) = 250(8)
2(8) = 2000
You can read 2000 words in 8 minutes.
It is given in the question that
A projectile is fired at 657 mi/hr. how fast is that in meters per second? use the conversion factor 1 mile = 1610 m.
So we need to convert miles per hour to meters per second.
And it is given that 1 mile equals to 1610 meters and 1 hour equal to 3600 seconds.
So we will get
Answer:
x = 65
Step-by-step explanation:
<h3>Check the possibilities:</h3><h2>A:</h2>
u(n)=n-1
u(6)=6-1= True
u(10)=10-1≠7 False
<h3>
A is eliminated.</h3>
<h2>
B:</h2>
u(n)=2n-7
u(6)=2(6)-7=12-7=5 True
u(10)=2(10)-7=20-7≠7 False
<h3>
B is eliminated.</h3>
<h2>
C:</h2>
u(n)=0.5n+2
u(6)=0.5(6)+2=3+2=5 True
u(10)=0.5(10)+2=5+2=7 True
<h2>
C is your answer.</h2>
<h3>
Check D although we know it's C:</h3>
u(n)=n/6 +4
u(6)=6/6 +4=1+4=5 True
u(10)=10/6 +4=2.5+4=6.5≠7 False
