Find the exact length of the third side.

The answer to your question is   b = 42

Step-by-step explanation:

Data

hypotenuse = 70

leg 1 = 56

Process

1.- To solve this problem use the Pythagorean theorem.

             c² = a² + b²

c = hypotenuse

a = 56

b = x

2.- Solve for b

              b² = c² - a²

3.- Substitution

              b² = 70² - 56²

4.- Simplification

               b² = 4900 - 3136

               b² = 1764

5.- Result

               b = 42

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
