Answer:
8x^2 + 34; 45.52 centimeters
Step-by-step explanation:
The perimeter is twice the sum of adjacent edges of a rectangle:
P = 2((2x^2 +9) +(2x^2 +8)) = 2(4x^2 +17)
P = 8x^2 +34
Then when x=1.2, the perimeter is ...
P = 8(1.2^2) +34 = 8·1.44 +34 = 45.52 . . . . cm
I think that maybe 16 is rational
Answer:
(a) 63 (b) 99
Step-by-step explanation:
(a)
length x 2 = 150
275-150=126/2= 63
(b)
8712/88= 99
Answer:
C(t) = $28,000(0.811)^t (Answer A)
Step-by-step explanation:
The value of the car is decreasing. Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation.
Then the desired formula is C(t) = $28,000(0.811)^t (Answer A)
