Why?</h2>
Since a right triangle is formed, we can calculate the resultant force using the Pythagorean Theorem which states that:

Where,
c, is the hypothenuse.
a, is one triangle leg.
b, is the other triangle leg.
So, we are given the information:


So, calculating the resultant force (hypothenuse), we have:

Hence, the expression that would find the result velocity is:
a) [tex]Resultant=\sqrt{22^{2} +4^{2} }[/tex]
Have a nice day!
Using the distributive property the product is -12x-20. To distribute you take the numbers and or variables outside of the paranthesis and multiply it by each one in the parenthesis such that 4x is multiplied by -3x getting -12x and multiplying 4x by -5 and the product is -20x and all together the answer is -12x-20
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%
