Using the distance formula:

AB^2 = (-2-6)^2 = (2-2)^2
          = 64
    AB = 8 units
BC^2 = (6-0)^2 + (2-8)^2
          = 36 + 36
          = 72
    BC = 6 root 2
AC^2 = (-2-0)^2 + (2-8)^2
          = 4 + 36
          = 40
    AC = 2 root 10

Perimeter = 8 + 6 root 2 + 2 root 10
                 = 2 (4 + 3 root 2 + root 10) units

Samantha puts an initial $500 into a savings account. The account has a 4% annual compound interest rate. What is the function t
konstantin123 [22]
Hello! I can help you with this!

a. The function that would best represent Samantha's account is f(5) = 500(1 + 0.04)^5. This is because $500 is the principal, the interest rate is 4%, and we're looking for the amount in the savings account 5 years later.

b. Okay. 1 = 0.04 is 1.04. 1.04^5 is 1.216652902. It's a long decimal, but don't delete it. Multiply that decimal by 500 and you get 608.32645 and other numbers behind it or 608 when rounded to the nearest dollar. Samantha will have about $608 in her savings account in 5 years.

Note: The formula goes like this: f(x) = P(1 + r)^x. This means, you add 1 and the simple interest rate in decimal form together and raise that up by the exponent. There is no shortcuts for this, so you'll have to use the calculator. There will be a very long decimal, but don't clear it. Instead, multiply it by the principal to get the answer. It seems very complicating, but if you do this right, it gets easier overtime and you'll make less errors. There are more complex problems out there, so this formula is very important, but it was kept simple for this question.

For each parallelogram find the length of the base or height the first parallelogram has the area of 60 meters square the base i
Lynna [10]

Answer:

  5 m

Step-by-step explanation:

You know the area of a parallelogram is the product of its base length and height:

  area = base × height

Fill in the given values, and solve for height:

  60 m² = (12 m) × height

  (60 m²)/(12 m) = height = (60/12) m

  height = 5 m

The height is 5 meters.
