In 1985, the price of a gallon of milk cost about $2.20 per gallon. In 2005, the price of a gallon of milk cost about $3.50 per
Assoli18 [71]

the percent increase in the price of a gallon of milk from 1985 to 2005 is 59%

Define percent increase

Percent increase can be described as the rise in the value of an item, in this case the value is milk.

Write out the parameters

In 1985 the price of a gallon of milk is $2.20

In 2005 the price is $3.50

Formula for percent increase

new price-old price/new price × 100

Calculate the percent increase

new price= $3.50

old price= $2.20

= 3.50-2.20/2.20

= 1.3/2.20

= 0.59 × 100

= 59%

Hence the percent increase from 1985 t0 2005 is 59%

What is the minimum value of F(x)= 10x^{2} -6x-3<br> 3/10 or -39/10
kolezko [41]

Answer: 3/10

Step-by-step explanation:

Take the derivative of 10x^2-6x-3 to get 20x-6. Set that equal to 0 to find the critical points of the function. The critical points is when the slope is either 0 or undefined.

Now do:

20x-6=0\\20x=6\\x=\frac{6}{20} = \frac{3}{10}

There are quite a few more steps to actually find the minimum, but for this example you can automatically assume its a minimum because it is the only critical point of the function. Ill show you these extra steps tho.

Plug in two numbers into the derivative. One that is less than 3/10 and one that is greater than 3/10. The numbers 0 and 1 are fine. When x = 0, the function is -6. When x = 1, the function is +14. A switch from negative to positive indicates a minimum value
