Answer:

Step-by-step explanation:

Well. There are many possibilities. There are 26 letters in the alphabet. Take the K and W out. You have 24. So, just go through every letter. Putting  them together to make a name, it could be anything really. It might take a while, but write out the alphabet, and see what names you can make starting with K and W. I hope this helped!! :)

The polynomial 40p + 50f + 90 represents the amount of ink, in milliliters, of printing "p" poster and f flyers in
Troyanec [42]

color : 40p + 50f + 90

b&w : 15p+20f + 45

p = 26

f = 45

[substitute the values given]

color : 40(26) + 50(45) + 90

b&w : 15(26)+20(45) + 45

[solve the equation]

color : 3380

b&w : 1335

[subtract to see how much ink is saved]

3380 - 1335 = <u>2045</u>

LUCKY_DIMON [66]

Answer:

Part A:  A(m(t)) = π(81t²); Part B:  1017.36

Step by step explanation:

Part A:  

To find A(m(t)), we substitute our value for m(t), 9t, in place of m:

A(m(t)) = πm² = π(9t)² = π(81t²)

A(m(t)) = π(81t²)

Part B:  

Substitute 2 in for t:

A(m(2)) = π(81(2²)) = π(81(4)) = 3.14(324) = 1017.36
