What is the length of ac? round to the nearest tenth.

AC ≈ 10.5 cm (1 dec. place )

Step-by-step explanation:

Given

tan55° =

Multiply both sides by b

b × tan55° = 15 ( divide both sides by tan55° )

AC = b = ≈ 10.5 cm

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
