- Quadratic Formula:
, with a = x^2 coefficient, b = x coefficient, and c = constant.
Firstly, starting with the y-intercept. To find the y-intercept, set the x variable to zero and solve as such:
<u>Your y-intercept is (0,-51).</u>
Next, using our equation plug the appropriate values into the quadratic formula:
Next, solve the multiplications and exponent:
Next, solve the addition:
Now, simplify the radical using the product rule of radicals as such:
- Product Rule of Radicals: √ab = √a × √b
√1224 = √12 × √102 = √2 × √6 × √6 × √17 = 6 × √2 × √17 = 6√34
Next, divide:
<u>The exact values of your x-intercepts are (-4 + √34, 0) and (-4 - √34, 0).</u>
Now to find the approximate values, solve this twice: once with the + symbol and once with the - symbol:
<u>The approximate values of your x-intercepts (rounded to the hundredths) are (1.83,0) and (-9.83,0).</u>
The area used to make the triangular flag is 15 square inches.
Given
Two of the sides are 8 in.
Lila made a triangular flag to cheer on her favorite sports team.
The perimeter of the flag is 20 inches.
<h3>What is Heron’s formula?</h3>Semi-perimeter is equal to the sum of all three sides of the triangle divided by 2.
Then,
The value of S is;
Therefore,
The area used to make the triangular flag is;
Hence, the area used to make the triangular flag is 15 square inches.
