What is the perimeter of parallalogram qrst, shown. a.21.62. b 26.65. c 20.33. d 17.16

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

h(x) * s(x) = 200(1.05)^(x - 1)

Step-by-step explanation:

Our interest equation is s(x) = (1.05)^(x - 1). This is actually a part of a bigger formula for calculating the amount of money accumulated including interest:

A = P(1 + r)^n, where A is the total, P is the principal amount (initial amount), r is the interest rate, and n is the time

Here, we technically already have the (1 + r)^n part; it's just (1.05)^(x - 1). The principle, though, will actually be the 200 because she starts out at $200.

Thus, to combine these, we simply multiply them together to get:

h(x) * s(x) = 200(1.05)^(x - 1)
