1.181 is the decimal equivalent to 13/11
Solution:
we have been asked to find a function for the given sitatution
The given situation is
A movie store sells DVDs for $11 each. what is the cost C of n DVDs.
Cost of 1 DVD is $11, then the cost of 2 DVDS will be 2x11=$22.
Cost of 1 DVD is $11, then the cost of 3 DVDS will be 3x11=$33.
......................................................................................................................
.......................................................................................................................
Cost of 1 DVD is $11, then the cost of n DVDS will be nx11=$11n.
Since the price is increasing exactly by $11 for each additional DVDS so the Graph will be discrete.
Hence the correct option is C=11n, Discrete.
3. f(-6) = 12+1 =13
f(-2) = 4+1 = 5
f(0) =1
Range {1,5,13}
4. f(-2) = (-2)^3+1 =-7
f(-1) = (-1)^2 +1 =0
f(3) = (3)^3 +1 = 28
Range = {-7,0,28}
5.the sequence is arithmetic
d= -11+19 = 8
an = a1 + d(n-1)
an = -19 +8(n-1)
6.l =w+5
a =l*w
a(w) =(w+5) * w
a(w)= w^2 +5w
f(w) = w^2 +5w
f(8) = 8^2 +5(8)
f(8) = 64 +40
f(8) =104 in^2
A = 3 b = -16 and c = 2
the radicand would be
sq root (b^2 -4*a*c) =
sq root (256 -4*3*2) =
sq root (232)
So the roots will be real and not complex.
Just add 360 to -800 until you end up with an angle between 0 and 360:
-800+360=-440
-440+360=-80
-80+360=280
So the angle is 280 degrees.
