Is this set of numbers a Pythagorean triple? yes or no
Kaylis [27]

<u>Answer</u>:- No.

<u>Explanation</u> :-

<u>Substitute these numbers in pythagoras theorem to check if the set of numbers is a pythagorean triplet.</u>

<u>Pythagoras theorem</u> :- sq. of hypotenuse (longest side) is equal to the sum of sq.s of other two sides.

<u>Here</u>,

hypotenuse = 12 (as it is the longest side)

and other two sides are 6 and 9.

----> 6^2 + 9^2 = 12^2

----> 36 + 81 = 144

----> 117 = 144

Since, LHS is not equal to RHS, this set of numbers is not a pythagorean triplet.

A fast food restaurant sells between 164 and 328 hamburgers per day. If the company profits $82.00 per 82 hamburgers sold, appro
murzikaleks [220]
If the company earns $82 per 82 hamburgers then that means that the company earns $1 per burger sold. Therefore we are able to deduct that the company profits in between $59,860 and $119,720 a year. We know this because the minimum number (164) x 365 is 59,860 and the maximum number (328) is 119,720.

What are the zeros (x intercepts) of the quadratic function?
topjm [15]

Answer:it’s d

Step-by-step explanation:

The parabola (u sharp thing lol) passes the horizontal (x axis) and it touches the horizontal line twice... this is always. If you look closely it touches 1, -5 ( the negative comes from being to the left side) and since this is your horizontal line both these number go first (1) (-5) then you just include the 0s because the y intercept is always like that majority of times but also bc it’s not touching that lines (vertical line heheh) hope that makes sense.
