When the Olympic Games were held outside Mexico City in 1968, there was much discussion about the effect the high altitude (7340

feet) would have on the athletes. Assuming air pressure decays exponentially by 0.4% every 100 feet, by what percentage is air pressure reduced by moving from sea level to Mexico City?

Answer: By moving from sea level to Mexico City  air pressure is reduced by 25%.

Step-by-step explanation:

Hi, to answer this we have to apply a decrease rate formula

P0 (1-r)^x

Where:  

p0= initial pressure

r = decrease rate. (0.4 = 0.4/100=0.004 decimal form)

x = feet (hundredths, since the air pressure decays every 100 feet we have to divide the input value by 100)

Replacing with the values given

P0 (1- 0.4/100)^(7340/100) =

P0 (0.996)^73.4 =

P0 ( 0.75)=

The air pressure at Mexico City compared to the sea level is 75% (0.75 x 100 =75%)

To obtain the percent decrease  

100% -75% =25%

Average rate of change is defined by (y^-y)/(t^-t) where the ^ means the final(so final y and final t)
So you'd do (8.75-2.75)/(12-4) which is 6/8 which is 3/4 of a dollar per week

The conversion of square feet to square yards can be represented by direct variation. Three square yards are
grandymaker [24]
<h3>The constant of variation is \frac{1}{9}</h3><h3>The equation is y=\frac{1}{9}x</h3>

<em><u>Solution:</u></em>

Given that,

The conversion of square feet to square yards can be represented by direct variation

Let y represent the number of square yards

Let x be the number of square feet

y \propto x

y = kx ------ eqn 1

Where, "k" is the constant of variation

Three square yards are  equivalent to 27 square feet

Substitute, y = 3 and x = 27 in eqn 1

3 = k \times 27\\\\k = \frac{3}{27}\\\\k = \frac{1}{9}

Thus the constant of variation is \frac{1}{9}

<em><u>What is the equation representing the direct variation?</u></em>

Substitute k = 1/9 in eqn 1

y = \frac{1}{9}x

Thus the equation is found
