History: In the 1800s, women often carried pleated fans. One of the fans on display at the Smithsonian is
7 inches long and, when fully open, sweeps out an angle of 80°. How long is
the trim, to the nearest tenth of an inch, on the curved edge of the fan?
O 15 inches
9.8 inches
19.6 inches
O 56 inches

9.8 inches

Step-by-step explanation:

θ = 80° (π/180) = 4π/9 radians

arclength = Rθ = 7(4π/9) 28π/9 = 9.8 inches

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
