Answer:
19%
Step-by-step explanation:
An exponential relationship is modeled by y = 31(0.81)^x , what is the percent rate of change for this function?
From the above exponential relationship given, we can see that this exponential relationship is an exponential decrease.
Where the formula:
y = a(1 - r)^t
Where a = Initial amount
r = rate of change in percent
t = time in years
y = a(1 - r)^x = y = 31(0.81)^x
1 - r = 0.81
r = 1 - 0.81
r = 0.19
Converting 0.19 × 100
= 19%

Answer:
B. 26.65
Step-by-step explanation:
QRST is a parallelogram
so
QR = TS = 7
and
QT = RS = √[(6)^2 +(2)^2] = √40 = 6.3246
So the perimeter of parallelogram:
= 2(7) + 2(6.3246)
= 14 + 12.6492
= 26.65
Answer is B. 26.65
