the function f(x) = 15(1.4)^x represents the area in square inches of a photograph after it has been enlarged x times by a factor of 140%. what is the area of the photograph after it has been enlarged 4 times?
a. 5.6 square inches
b. 57.624 square inches
c. 41.16 square inches
d. 560 square inches

57.624 in²

Step-by-step explanation:

f(4) = 15(1.4)^4

= 15 (14/10)^4

= 15 (7/5)^4

= 15 (2401/625)

= 7203/125 = 57.624 in²

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
