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

So what you got to do is divide them perseay use a calculator for the first one 2/15 what would that be in a decimal 0.13333333333333 what ever on has 0.13333333  or something else repeating that is the one that you will circle 11/20=0.55   17/40 =0.425 1/2=0.5 so you answer would be 2/15

A quadrilateral has angle measures of 41 52 and 54 which is the measure of the last angle
nexus9112 [7]

Answer:

213 degrees

Step-by-step explanation:

A quadrilateral has an internal measurement of angles of 360 degrees.  Given that we have 3 measures of the angles, we simply need to find the 4th.  This can be accomplished with the following equation:

x + 52 + 54 + 41 = 360

x + 52 + 95 = 360

x + 147 = 360

x = 213

Hence, the measure of the final angle is 213 degrees.

Cheers.
