The equation is:
y = 10 sin(π/15 t) + 30 
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.

Hope this helps :)

A drive-in theater costs $20 per car, plus an additional fee of $4 per person. The cost, C, of the movie when p people are in th
ozzi

Answer:

P=\frac{C}{4} -5

Step-by-step explanation:

Step one:

given

cost  per drive= $20

additional fee per person= $4

let the number of persons be p

and the total cost be C

The total cost function is expressed as

C=20+4p

Step two:

Required:

<u><em>We want to make P subject of the cost function </em></u>

Take 20 to the other side we have

C-20=4p

divide through by 4

P=C-20/4

simplify

P=C/4-5

P=\frac{C}{4} -5

patriot [66]

Answer:

4x² + 12x + 9

Step-by-step explanation:

<h3>Using identity: </h3>

(a +b)² = a² + 2ab + b²

Here, a = 2x  & b = 3

(2x +3 )² = (2x)² +  2*2x*3 + 3²

              = (2x*2x)  + 12x + 3*3

             = 4x² + 12x + 9

Which equations could you use the division property of equality to solve?
disa [49]

Answer:

2.35y = 4.70

4 = 10w

55x = 111

Step-by-step explanation:

Hi, the division property of equality states that if we divide both sides of an equation by a non-zero number, the equality remains. (Both sides remain equal).

So, the equations that we have to use the division property of equality to solve are:

  • 2.35y = 4.70

Dividing both sides by 2.35:

2.35y /2.35= 4.70/2.35

y= 2

  • 4 = 10w

4/10=10w/10

0.4=w

  • 55x = 111

55x/55 =111/55

x = 111/55
