Answer:
a = 3
b= -1
c = 5
X = (-b +- sqrt [b^2 - 4ac]) / 2a
X = (--1 +- sqrt (1 - 4*3 * 5)) / 2* 3
x = (1 += sqrt (1 -60)) / 6
x1 = (1 + sqrt (-59)) / 6
x2 = (1 - sqrt (-59)) / 6

A) (the first data set)
Step-by-step explanation:
It is the only one that has enough numbers to be represented by the histogram
Answer:
(x - 3)^2 + (y - 4)^2 = 3^2
Step-by-step explanation:
Notice that both endpoints are on the vertical line x = 3. Thus, to determine the diameter of this circle, we need only subtract 1 from 7, obtaining 6. The diameter is 6, so the radius is 3.
The center is on the vertical line x = 3 and is halfway between the endpoints of the diameter, that is, at y = 4. (3, 4) describes this point.
Then we insert the known quantities into the general equation for a circle with center at (h, k) and radius r: 3 for h, 4 for k and 3 for r:
(x - 3)^2 + (y - 4)^2 = 3^2 is the desired equation.
Answer:
10 feet
Step-by-step explanation:
Since the bird is 8 feet above and the badger is 2 feet below, you want to add the two lengths to get 10 feet between them.
