Answer:

1. 14.5

2. 16

Step-by-step explanation:

1. a^2 + b^2 =c^2

20^2 + 21^2 = c^2

400 + 441 = c^2

841 = c^2

\sqrt{841} = \sqrt{c}

29 = c

29/2 = x

14.5 =x

2. c^2-b^2 = a^2

34^2 - 30^2 = a^2

1156 - 900 = a^2

256 = a^2

\sqrt{ 256 } = \sqrt{a}

16 = a

1. Kyle and John are twins who decided to plan an imaginary trip that started with cliff jumping. There were two different spots
Vikki [24]

Answer:

a) Δx = -35ft

b) Δx = -25ft

c) Kyle traveled 10ft more than John

Step-by-step explanation:

We define a coordinate reference system() in which y = 0 corresponds to the water surface.

a) The initial position of Kyle in our coordinate reference system is:

   x_{o} = 20 ft

   and his final position is:

   x_{f} = -15 ft

   Therefore, he traveled

   Δx = x_{f} - x_{o} = -15 - 20 = -35 ft

b) The initial position of John in our coordinate reference system is:

   x_{o} = 15 ft

   and his final position is:

   x_{f} = -10 ft

   Therefore, he traveled

   Δx = x_{f} - x_{o} = -10 - 15 = -25 ft

c) Then, Kyle traveled 10ft more than John

Solve the formula for the indicated variable <br> A=1/2bh solve for h
vfiekz [6]

Answer:

h=A*2b

Step-by-step explanation:

A=1/2bh

1/2bh=A

1/2bh÷1/2bh=A÷1/2bh (the 1/2b will cancel with the 1/2b on the left leaving h)

h=A*2b
