What is the minimum value of y =(x-1)2 (squared) +3

1 answer:

4 0

The minimum is X=1 and Y=3, so the minimum is x=3. Use a graphing calculator then Google Search, "How to find the minimum of a graph using a graphing calculator.". The process of this is way to long to explain here, and is best explained visually.

A grocery store sells a 6-pack of bottle water for $3.79, a 9-pack for $4.50, and a 12-pack for $6.89. Which package costs the l

stiks02 [169]

Cost per bottle

6 pack is 3.79 so the cost per bottle is 3.79/6=$0.631666666666667 per bottle

9 pack is 4.50 so the cost per bottle is 4.50/9=$0.50 per bottle

12 pack is 6.89 so the cost per bottle is 6.89/12=$0.574166666667 per bottle

0.63>0.57>0.50

the one that costs the least per bottle is the 9 pack which costs $0.50 per bottle

Answer:

$\boxed{\boxed{\pink{\bf \leadsto It \ will \ take \ 5 hours \ to \ travel \ 300 \ miles. }}}$

<h3>Step-by-step explanation:</h3>

According to Question , a plane travels 120 miles in 2 hours. So here we will use unitary method .

$\bf\implies If \ it \ covers \ 120 \ miles \ in \ 2 \ hours \\\\\bf\implies Then \ one \ mile \ will \ be \ covered \ in \ \dfrac{120}{2} hrs \\\\\bf\implies Hence \ 300 \ miles \ will \ be \ covered \ in \ \dfrac{2}{120}\times 300 hrs = \red{5 \ hours }$

<h3>Hence it will cover 300 miles in 5 hours .</h3>

Here it was a case of direct proportion in which if two things are directly proportional to each other. If one thing thing increases then the value of second also increases. Here if the time increases then the distance also increases
