Answer:
72X + 54
Step-by-step explanation:
A.
continuious means they both approach the same number as they approach 1
basically, find the vallues of q in terms of p for which both of them equal 1
so
1+2p(1-1)+(1-1)^2=1 (this simplifies to 1=1 so don't mess with the p)
q(1)+p=1, q+p=1, q=1-p
the value of q that will make it continous at x=1 is 1-p
B. find the values of p and q such that their derivitives are equal at x=1
first one's derivitive:
2px+2x-2, at x=1, 2p+2-2=2p
2nd one's derivitive:
q
so
2p=q
from the value in part a
q=1-p
2p=1-p
add p to both sides
3p=1
divide by 3
p=1/3
q=1-1/3
q=2/3
the function is
1+(2/3)(x-1)+(x-1)^2 for x≤1 and
(2/3)x+(1/3) for x>1
C. take the derivitive twice to get
0 and
0
both same deriritive
find if they have the same value
well, 0=0
yes
A. q=1-p
B. p=1/3, q=2/3
C. yes, both have value of 0 and change of slope is 0
The tiles are identical, so you would need them to fit exactly.
if he uses 144 tiles to cover the floor, the area would be 72/144 = 0.5 square feet
this is just one example
