Answer:
and ![(3,0)](https://tex.z-dn.net/?f=%283%2C0%29)
Step-by-step explanation:
Think about it.
What two numbers multiply to -15 and add up to 2?
The answers are 5 and -3.
So plug that into the factored form of a parabola.
![y=(x+5)(x-3)](https://tex.z-dn.net/?f=y%3D%28x%2B5%29%28x-3%29)
To find the x-intercepts, plug in 0 for
.
![(x+5)(x-3)=0](https://tex.z-dn.net/?f=%28x%2B5%29%28x-3%29%3D0)
Since we are multiplying, at least one of the terms has to equal 0.
![x+5=0 \\ x-3=0 \\ \\ x=-5,3](https://tex.z-dn.net/?f=x%2B5%3D0%20%5C%5C%20x-3%3D0%20%5C%5C%20%5C%5C%20x%3D-5%2C3)
So the x-intercepts are
and
.

Step-by-step explanation:
Answer:
d) 0.8 mile
Step-by-step explanation:
Coordinate of object B = (6, 6)
Coordinate of object C = (1, 4)
Coordinate of the archaeologist = (6, 1)
✍️Distance between Object B (6, 6) and the archaeologist (6, 1):
Distance = |6 - 1| = 5 units = 5 miles
✍️Distance between Object C (1, 4) and the archaeologist (6, 1):
Using the distance formula,
, we would have:
![d = \sqrt{(6 - 1)^2 + (1 - 4)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%286%20-%201%29%5E2%20%2B%20%281%20-%204%29%5E2%7D%20)
![d = \sqrt{(5)^2 + (-3)^2}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B%285%29%5E2%20%2B%20%28-3%29%5E2%7D%20)
![d = \sqrt{25 + 9}](https://tex.z-dn.net/?f=%20d%20%3D%20%5Csqrt%7B25%20%2B%209%7D%20)
(nearest tenth)
Comparing how far each object is from the archaeologist, object C is 0.8 mile (5.8 - 5 = 0.8) farther than object B.
