Once his parachute is open, a skydiver descends at a rate of 25 feet per second. 90 seconds after the parachute opens, his altit

ss7ja [257]

Using the information given and linear function concepts, it is found that:

a) The equation is: $y(t) = -25t + 5000$ .

b) The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.

c) It takes 200 seconds for the skydiver to reach the ground.

<h3>What is a linear function?</h3>

A linear function is modeled by:

$y(t) = mt + b$

In which:

m is the slope, which is the rate of change, that is, by how much y changes when t changes by 1.

b is the y-intercept, which is the value of y when x = 0.

Item a:

The skydiver descends at a rate of 25 feet per second, hence $m = -25$ .

Then:

$y(t) = -25t + b$

<u>90 seconds after the parachute opens, his altitude is 2750 feet</u>, which means that when $t = 90, y = 2750$ , which is used to find b. Then:

$2750 = -25(90) + b$

$b = 5000$

Hence, the equation is:

$y(t) = -25t + 5000$ .

Item b:

Time is in seconds, hence, this is y(120).

$y(120) = -25(120) + 5000 = 2000$

The skydiver’s altitude after the parachute has been open for 2 minutes is of 2000 feet.

Item c:

The time it takes to reach the ground is t for which y(t) = 0, hence:

$-25t + 5000 = 0$

$25t = 5000$

$t = \frac{5000}{25}$

$t = 200$

It takes 200 seconds for the skydiver to reach the ground.

How can you use the transformation to prove two triangles are congruent

Alla [95]

You could use a translation to move one to the same position as the other and compare if they have the same orientation (like both are pointing up).
If not, you could use rotation to do so, then use translation. Sometimes even reflections might work, but that's a bit more complex.

rjkz [21]

The answer should be $10.80.
The reason being. 180 x 6% = 10.80. You would then add 10.80 to 180 to get the total which would be $190.80. But you only need what the tax would be so the tax would be $10.80
