Answer:
f(2)=0
Step-by-step explanation:
You plug in 2 for any X's in the equation
f(2)=2^2-4
Volume = π (3.14)×22^2×12.5 = 18,997 inches³
3pm we know this because 5^3= 125 so then we plug in numbers for the exponent in this case 6 which equals 15,625 now 9am plus 6 is 3pm
(a). The element a₂₁ is the number of boys enrolled in Lacrosse.
(b). The address is a₁₂.
(c). [196 174]
[136 169]
[214 242]
(d). The matrix represents the number of boys and girls from towns A and B enrolled in different sports classes.
(e). 1.125 A = [108 90 ]
[72 99 ]
[117 135]<span />
To do this, you'll have to get loris and doris to the same amount of time, we can already tell loris makes 40 bracelets in 100 minutes but we are still missing 20 minutes, so we got to do some math(Ofc we do its mathematics) if you divide 50 by 20 you'll get 2.5 which is how many minutes it takes to make a bracelet. So now we can go back to that missing 20 minutes, if you divide 20 by 2.5, you'll get 8. So in 2 hours loris makes 48 bracelets(20 + 20(50 hours each)=40 + 8(the missing 20 minutes) = 48) But here is the tricky part it says per an hour, so we need to reduce both by half, so loris makes 24 bracelets an hour and doris makes 22 bracelets an hour so loris makes 2 more bracelets and hour than doris... hope i've helped!
