Answer by YourHope:


Hi! :)


The graph shows f(x) = [1/2]^x and its translation, g(x). Which describes the translation of f(x) to g(x)?


Translation of four units up! The f(x) function cannot possibly be f(x)=1/2, though, because that would be a horizontal line through y = 1/2 and that function is clearly not a horizontal line.  So whatever f(x) is really, add 4 to the tail end of it to show its translation!

“A patchwork blanket is made up of 10 identical squares. Liam has made 14 squares,Raj has made 12 squares and Gemma has made 15
steposvetlana [31]
Well, assuming that Liam, Raj, and Gemma all have squares identical to each other, then you would first add them all up. 14+12+15=41. Then, you would divide the total number of squares by the number of squares in a quilt. 41/10=4.1, or 4 1/10.
Hope this helps!

Answer:

B)

4.5 cm

Step-by-step explanation:

The formula for arc length when our central angle is in degrees =

2πr(θ/360)

θ = 86°

Diameter = 6cm Radius = Diameter /2

Radius = 6cm/2 = 3cm

Hence,

Intercepted arc length = 2 × π × 3 (86/360)

= 2 × π × 3 × 0.2388888889

= 4.5029494701 cm

Approximately = 4.5 cm

Option B is the correct answer
