D
Step-by-step explanation:
I've had these kind of questions on tests
The two solutions are 3 and 6. This means that you can write your parabola as

Answer:
22 1/4 feet
Step-by-step explanation:
you can sketch this problem to be a right triangle with a hypotenuse of 24 feet and one leg of 9 feet (17 - 8).
use Pythagorean Theorem to find the base side, which represents the distance between the posts
a² + 9² = 24²
a² + 81 = 576
a² = 576 - 81
a² = 495
a = 
a =
·
= 3
, which is approx 22.25
20 x 5 will give your the best estimate of 23x 4.8 because 20 x 5 = 100 and 23 x 4.8 = 110 hope this helped :)
To find the slope given two points:
(-2, 5) and (1, 4)
subtract the first y from the second y /subtract the first x from the second x
4-5 / 1- -2
-1/3
The slope of the line that passes through the given points is -1/3
Hope this helps :)
