lina2011 [118]

Answer:

The greatest amount of fizzy drink he can make is 480 ml

Step-by-step explanation:

The ingredients for a fizzzy drink is 5 parts lime juice and 3 parts lemonade

Therefore, we have a total portion of 5 + 3 = 8 parts

Since there ar more parts of lime juice per fizzy drink, we calculate based on lime juice

Also dividing the proportions by we get

5/5 part lime juice and 3/5 parts lemonade or

1 part lime juice and 3/5 parts lemonade or

Thus we have 300 ml lime juice and 3/5× 300 ml lemonade or

300 ml lime juice and 180 ml lemonade = 480

The greatest amount of fizzy drink he can make = 480 ml.

Find the global maximum and global minimum values (if they exist) of x 2 + y 2 in the region x + y = 1. If there is no global ma

Grace [21]

Given that $x+y=1$ , we have $y=1-x$ , so that

$f(x,y)=x^2+y^2\iff g(x)=x^2+(1-x)^2$

Take the derivative and find the critical points of $g$ :

$g'(x)=2x-2(1-x)=4x-2=0\implies x=\dfrac12$

Take the second derivative and evaluate it at the critical point:

$g''(x)=4>0$

Since $g''$ is positive for all $x$ , the critical point is a minimum.

At the critical point, we get the minimum value $g\left(\frac12\right)=f\left(\frac12,\frac12\right)=\frac12$ .

Write an inequality for the graph. Then, in words, describe all the values of x that make inequality true.

GarryVolchara [31]

The equivalent inequality for the number line is x < 8
The equivalent inequality for the number line is x ≥-5

<h3>Inequality functions </h3>

The inequality expression is an expression not separated by an equal sign,

11) The equivalent inequality for the number line is x < 8. This shows that the values of x that make it true must be less than 8.

Note that the sign is less than because the circle is open and moves towards the left of the number line

11) The equivalent inequality for the number line is x ≥-5. This shows that the values of x that make it true must be greater than or equal to 8.

Note that the sign is greater than or equal to because the circle is closed and moves towards the right of the number line
