For the answer to the question above,  we will use this formula to solve this problem
<span>d = kv^2 </span>

<span>plugging in, </span>
<span>4.2 = k*10^2 </span>
<span>k = 0.042 </span>

<span>d = 0.042v^2 </span>

<span>the revoised equation will be </span>
<span>d = 0.9*0.042v^2 , i.e. </span>

<span>d = 0.0378v^2 

I hope my answer helped you</span>

A car trip is 1/2h shorter that a bus trip. How long is the car trip if the bus trip is 3/4h?
IgorLugansk [536]

Answer:

1/4h

Step-by-step explanation:

The car trip is 1/2h shorter than the bus trip.

The bus trip is 3/4h long.

Therefore, the length of the car trip is:

3/4h - 1/2h = 1/4h

The car trip is 1/4h long.

Because the coefficient of x^2 is -1, we know that a will be -1.  Knowing that the coefficient of x is -4, we can calculate that p=2.  Thus, we have -1(x+2)^2+q is our equation.  This is equal to -x^2-4x-4+q.  As the constant term must be 2, we can then see that q is 6.

As such, we have -1(x+2)^2+6=0 as our factorization.

To solve this equation, we can use the quadratic formula.  Plugging in values, we have:

\frac{4+-2 \sqrt{6} }{-2}
which is equal to: (when the fraction is simplified)
-2+- \sqrt{6}

Ratio expresses the relationship between two numbers. It shows the frequency of the number of times that one value is contained in another number. The sign used to represent ratios is :

<h3>Determining the total cards made. </h3>

Total card = (sum of ratios x number of get well cards) / ratio of get well cards

(11 x 60) / 5 = 132

<h3>Number of birthday cards made </h3>

6/11 x 132 = 72 cards
