Answer:
Length of hypotenuse of given triangle
= sqrt(356) (exact value)
= 18.87 (to 2 decimal places)
Step-by-step explanation:
Using the pythagorean Theorem,
The hypotenuse
c = sqrt(a^2+b^2)
= sqrt(16^2+10^2)
= sqrt(356) (exact value)
= 18.87 (to 2 decimal places)
There are 16 oz in a Pound. Take 14.99 and divide it by 16. This will give you the cost per oz. 14.99/16= .936875
Answer:
Therefore he should sell 25 units of tacos to minimize his cost .
The minimum cost is $240.
Step-by-step explanation:
Given function,

where C is the cost in dollar to sell x units of tacos.
We know that,
If a function y(x)= ax²+bx+c,
then the function is minimum at 
Here a= 1 , b= -50 and c= 865.
Therefore

Therefore he should sell 25 units of tacos to minimize his cost .
putting the value of x in the given function
C(25)=25²-(50×25)+865
=240
The minimum cost is $240.
