Pythagorean triples are given by the formula x^2-y^2, 2xy, and x^2+y^2. Use the formulas for the Pythagorean triples to find a right triangle with leg lengths of 16 and an odd number. Show all of your work for full credit.

Answers

Answer:

Let the unknown length be x

We have a formula to find the triplet of a right angle triangle

Put the given length equal to all three terms in the triplet

$2m,m^2-1,m^2+1$

put 16 equal to all above three but number comes out has to be integer.

$2m=16$

$\Rightarrow m=8$

Now, $m^2-1=16$

$m^2=17$ will not give integer.

And now, $m^2+1=16$

$m^2=15$ will not get integer value

Hence, the value of m will be 8

And substituting the value in the triplet formula we get

$2m=2\cdot 8=16$ which is given.

$m^2-1=64-1=63$ the other leg and is odd.

And $m^2+1=64+1=65$ the hypotenuse or the longest side.

Hence, 16,63 and 65 will form a right triangle

Pythagoras theorem is:

$\text{one side}^2+\text{other side}^2=hypotenuse^2$

Here, 16 and 63 are sides or legs and 65 is the hypotenuse.

Jim runs a food cart and during a busy outdoor festival he sold $7343.75 worth of food. he sells hot dogs for $2.95 and steak sandwiches for $9.95. if he sold a total of 985 items that day, how many of each item did he sell? and show your work

Answers

$7343 worth of food
$2.95 hot dogs (h)
$9.95 steak sandwiches (s)
985 items sold
so what you want to do is set up two equations
h+s=985
2.95h+9.95s=7343.75
solve one of these equations for a variable
h+s=985 subtract s
h=-s+985 plug into other equation
2.95(-s+985)+9.95s=7343.75 multiply out
-2.95s+2905.75+9.95s=7343.75 combine like terms
7s+2905.75=7343.75 subtract 2905.75 from both sides
7s=4438 divide by 7
s=634 then plug this number into one of the equations preferably the simpler one
h+634=985 subtract 634 from both sides
h=351
the amount of hot dogs sold is 351 and the amount of steak sandwiches is 634
i hope this helps.

The height of a ball in feet is modeled by $y = - 16x {}^(2) + 72x$
where X is the time in seconds after the ball is hit. How long is the ball in the air?

(May I also get steps on how to solve these kind of questions please?)

Answers

The value of time of the ball in the air is,

⇒ 4.5 seconds

What is Quadratic equation?

An algebraic equation with the second degree of the variable is called an Quadratic equation.

We have to given that;

The height of a ball in feet is modeled by the equation,

y = - 16x² + 72x

where, x is the time in seconds after the ball is hit.

Hence, For time of the ball in the air, we can plug y = 0 in above equation.

y = - 16x² + 72x

0 = - 16x² + 72x

Solve for x;

- 16x² + 72x = 0

- 4x (4x - 18) = 0

This gives,

4x = 18

x = 18/4

x = 4.5 seconds

Thus, The value of time of the ball in the air is,

⇒ 4.5 seconds

The answer to this question is 4.5 seconds. You can see from the graph that the ball is above the ground in the interval 0 < t < 4.5. It is at t = 4.5 where the graph touches the t-axis. When it touches the t-axis, then the height is 0 and therefore on the ground.
