Find the area of the following circle.
ra 9 yd.
Area
square yards.

Answers

Answer 1

Answer: Well the formula for this problem is A=3.14(pi) * radius * radius
So multiply 3.14 times 9 times 9. first multiply 9 with 9 you get 81 then you multiply 81 times 3.14 which equals 254.34. When you find the formula to this kinds of equations it's very easy all you have to do is plug in the numbers. Hope this helps :)

The sum of two numbers is 8, and their product is 80.a) Let x represent one of the numbers, and write an expression for the other number in terms of x. Use the expressions to write an equation that models the situation given above.
b) Use the Quadratic Formula to solve the equation. Write the solution in terms of i.

Answers

From their sum, the numbers are ' x ' and ' 8 - x ' .

From their product, x(8 - x) = 80 .

When you massage and manipulate this equation into the standard
quadratic form, you have

   x² - 8x + 80 = 0 .

Applying the quadratic formula to tease out the solutions of this equation,
we find that they are

   x = 4 + 64 i
and
   x = 4 - 64 i

Final answer:

The two numbers are represented by x and 8 - x. By setting x * (8 - x) = 80, we obtain a quadratic equation which can be solved using the Quadratic formula to find x = 2 and x = -40. However, we ignore the negative solution as we're dealing with positive numbers, resulting in 2 and 6 as the two numbers.

Explanation:

First, let's identify the two numbers. Let's let x represent one of these numbers. Because we're told that the sum of the two numbers is 8, we can express the second number as 8 - x.

Next, let's use this information to write our equation. We're told that the product of our two numbers is 80. In terms of x, we can write this as: x * (8 - x) = 80. Simplify this to obtain the quadratic equation: -x^2 + 8x - 80 = 0.

From this, we can apply the Quadratic Formula, which is x = [-b ± sqrt(b^2 - 4ac)] / (2a). Substituting a = -1, b = 8, and c = -80 into the formula, we find the solutions are x = 2 and x = -40. However, since we're dealing with positive numbers here, we can ignore the negative solution, leaving us with the two numbers as 2 and 6.
