Answer:
D: -96
Step-by-step explanation:
The sequence is to multiply by -4. 24 times -4 = -96
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)
I’m pretty sure it’s the first option
Answer:
9.75 feet
Step-by-step explanation:
You use the pythagorean theorem to solve. A is the unknown, while b is 7 feet, and c is 12 feet
A^2 + 7^2 = 12^2
A^2 + 49 = 144
Subtract 49 from both sides to get
A^2 = 95
then take the square root of both sides to get
A (the height) = 9.74679434481
I usually round to 2 decimal points to get the answer 9.75 feet.
