For t²+6t-20=0 (to find the vertex, or rather the x intercepts), we can add 20 to both sides to get t²+6t=20. Since 6/2=3, we can square 3 to get 9. Adding 9 to both sides, we get t²+6t+9=20+9=29=(t+3)². Finding the square root of both sides, we get t+3=+-√(29). Subtracting 3 from both sides, we get t=+-√(29)-3=either √(29)-3 or -√(29)-3. We have -√(29)-3 due to that t can either be negative or positive. Finding the average of the two numbers, we have
(√(29)-3)+(-√(29)-3./2=-6/2=-3, which is our t value of our vertex and since it's t² and based around t, that is our axis of symmetry. To find the y value of the vertex, we simply plug -3 in for t to get 9+(6*-3)-20=9-18-20=-29, making our vertex (-3, -29)
Answer:
The radius of the circle is 9 in
Choice C is correct
Step-by-step explanation:
254.4696 square inches. Whats the radius of the circle (use pie=3.1416.
The area of a circle with radius r is given as;
We substitute the given area and the value of pi given to solve for the radius;
23 because if there is 14 people remaining and 9 went home early so it would equal 23 because 14+9=23 so there was 23 people
at the party
