pi*r^2

pi*0.8^2 = 2.0106192983 m

approx = 2.011 m = 0.0020106192983 km = 0.002012 km approx

28800*0.0020106192983 = 57.905835791 km

What is the value of h(-7)<br><br> h(x) =|3x| -1
Art [367]

Answer:

20

Step-by-step explanation:

h(-7) just means that inside the x value, you replace the x with a -7.

h(-7) = |3x| - 1

h(-7) = | 3(-7)| - 1

h(-7) = | -21 | - 1

NOTE: -21 is inside |x|, those straight lines mean absolute value. No matter what, any negative number would turn into a positive one. And if it’s posititve, then it stays positive.

h(-7) = 21 - 1

h(-7) = 20

You are measuring the height of a statue. You stand 17 feet from the base of the statue. You measure the angle of elevation from
olga_2 [115]

Answer:

height ≈ 31 ft

Step-by-step explanation:

The illustration below will form a right angle triangle. He is standing 17 ft away from the base of the statue.  The angle of elevation from the ground to the top of the statue  is 61°. The height of the statue can be computed below.

adjacent side of the triangle = 17 ft

opposite side = a

Using SOHCAHTOA principle

tan 61° = opposite/adjacent

tan 61° = a/17

cross multiply

a = 17 tan 61°

a = 17 × 1.80404775527

a = 30.6688118396

a ≈ 31 ft
