Answer:

16ft

Step-by-step explanation:

The answer is 16ft because the area of a trapezoid is a + b/2  x h.

5 + 8/2 = 13/2 = 6.5

104/6.5 = 16

The height is 16ft.

Volgvan

Answer:1+10(1-\cos (\frac{\pi t}{9}))

Step-by-step explanation:

Given

radius of wheel r=10 m

Time period of Wheel T=18 s

and T\cdot \omega =2\pi , where \omega =angular velocity of wheel

\omega =\frac{2\pi }{18}

Let at any angle \thetawith vertical position of a point is given by

x=r\sin \theta

y=y_0+r(1-\cos \theta )

and \theta =\omega \times t

for velocity differentiate x and y to get

v_x=r\cos \theta =r\cos (\omega t)

v_y=0+r(\sin \theta )=r\sin (\omeag t)

Height at any time t is given by

h=1+10(1-\cos \theta )=1+10(1-\cos (\frac{\pi t}{9}))

in coordinates plane, what is the length of the line segment that connects points at (4, -1) and (9, 7) ? round to the nearest h
Travka [436]

Answer:

<h2>17.72</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have the points (4, -1) and (9, 7). Substitute:

d=\sqrt{(9-4)^2+(7-(-10))^2}=\sqrt{5^2+17^2}=\sqrt{25+289}=\sqrt{314}\approx17.72

How do I solve this?
Hunter-Best [27]

9514 1404 393

Answer:

  • x = 10
  • y = 19

Step-by-step explanation:

Consecutive interior angles between parallel lines are supplementary.

Let's start with x.

  (8x +40)° +(6x)° = 180°

  14x +40 = 180 . . . . . . . . . divide by °, collect terms

  14x = 140 . . . . . . . . . subtract 40

  x = 10 . . . . . . . . divide by 14

__

We can use the same approach for y:

  (7y)° +(3y -10)° = 180°

  10y = 190 . . . . . . . . . . . divide by °, add 10, collect terms

  y = 19 . . . . . . . . . . . divide by 10
