The full length of one line times the length of the line outside the circle is equal the the other line.
(7+x)*7 = (13 +8) * 8
Simplify:
7x +49 = 21 * 8
7x +49 = 168
Subtract 49 from each side:
7x = 119
Divide both sides by 7:
x = 17
The answer is B. 17
The tree will both be 5 feet after 2 years.
y=x + 3
y = 1/2x + 4
You need to find the area of the hexagon, and the area of the triangle.
The formula for the area of a triangle is
I hope this helps you a little.
<h3>#a</h3>
- Here we do not have a x in the function but we have a t, that's why I have written t-intercept instead of x-intercept.
Write the coefficients of the quadratic equation:
The discriminant is greater than 0, so the related quadratic equation has 2 real solutions.
<h3>#b</h3>
identify the coefficients of the quadratic function
<h3>' - - - - - - - - - - - - - - - - - - - - - - - - - - - - '</h3>
<em>The maximum value is 720 at t=12</em><em>.</em><em>.</em>
<h3>#c</h3>
- To find this we have replace t with 15
<em>The maximum height it will reach is 675 at t=15</em><em>.</em><em>.</em>
<h3>#d</h3>
- The domain of a quadratic function is the set of all real numbers
- The range is the set of all negative numbers to the maximum vertex
