How long does it take the ferris wheel to make one full rotation?h(t)=9sin(20(t-pi/2))+12        , h in metres and t in seconds

Answers

This is a circular ferris wheel, with diameter of 9 meters, and the axis
mounted 12 meters off the ground.  The equation is the height of the
a point that starts out level with the axis, at 't' seconds after the wheel
starts up. 

Now here's where things start to go awry:

The period of the revolution is the time it takes for the angle
inside the sine to change by 2pi .

20(t - pi/2) = 2pi

20t - 10pi = 2pi

20t = 12pi

t = 12pi/20 = 1.885 seconds

I can't help it.  All I did was the math, and that was bullet-proof. 
It was up to whoever wrote the question to guarantee that the
answer makes sense.

For one thing, I don't believe the 'pi/2' belongs inside the parentheses
with the 't'.  But even if we take the 'pi/2' out of the parentheses, that
still only makes the period 3.183 seconds, which is still an uncomfortable
number ... especially for the riders.

Given the function(x)=5x+4, find its inverse

Answers

the inverse is the reflection across the identiy line, the y=x line basically switch x and y and solve for y f(x)=5x+4 y=5x+4 swtich x=5y+4 solve for y x-4=5y (x-4)/5=y finverse=(x-4)/5
Make the function, f (x) into y. Then switch the variables y and x and solve for y : (x-4)/5

For each group of three forces below, determine whether the forces in each pair are pulling at right angles to each other.A. 12 lb, 13 lb, resultant force 19 lb, yes; 15 lb, 36 lb, resultant force 39 lb, yes

B. 12 lb, 13 lb, resultant force 19 lb, no; 15 lb, 36 lb, resultant force 39 lb, yes

C. 12 lb, 13 lb, resultant force 19 lb, yes; 15 lb, 36 lb, resultant force 39 lb, no

D. 12 lb, 13 lb, resultant force 19 lb, no; 15 lb, 36 lb, resultant force 39 lb, no

Answers

To condition in which we can justify if the forces are pulling at right angles to each other is that the sum of the squares of the two lesser number should be equal to the square of the third number. 

For the first set: 12 lb, 13lb, 19lb. 

                                             12^2 + 13^2 ≠ 19^2

For the second set: 15 lb, 36 lb, 39 lb

                                             15^2 + 36^2 = 39^2

The first pair of forces do not pull at a right angle while the second do.
Thus, the answer is letter B.

How many pairs of parallel sides does a rectangle have?

Answers

A rectangle has 2 sets of parallel sides. The top and bottom, then the left and right.

A rectangle is a quadrilateral which has two pairs of parallel sides.

The explanation in points is written below:

1. A rectangle is a quadrilateral with four sides and four angles.

2. Opposite sides of a rectangle are congruent (equal in length) and parallel.

3. This means that there are two pairs of sides that are parallel to each other.

4. The pairs of parallel sides are the top and bottom sides, and the left and right sides of the rectangle.

To summarize, a rectangle has two pairs of parallel sides: the top and bottom sides, and the left and right sides. This property is a defining characteristic of rectangles.

Given the equation y − 3 = one half(x + 6) in point-slope form, identify the equation of the same line in standard form.A. X-2y=-12
B.Y=1/2x
C.y=1/2x+6
D.y=1/2x+9

Answers

y - 3 = 1/2(x + 6) =...point slope form
y - 3 = 1/2x + 3
y = 1/2x + 3 + 3
y = 1/2x + 6...slope intercept form
-1/2x + y = 6...multiply everything by -2
x - 2y = -12 <=== standard form
C.y=1/2x+6, is fit....
