Answer:
Step-by-step explanation:
This is an arithmetic sequence
a1 = -2
Difference = 2nd term - first term
![=\frac{-5}{4}-[-2]\\\\=\frac{-5}{4}+2\\\\=\frac{-5}{4}+\frac{2*4}{1*4}\\\\=\frac{-5+8}{4}=\frac{3}{4}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-5%7D%7B4%7D-%5B-2%5D%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B4%7D%2B2%5C%5C%5C%5C%3D%5Cfrac%7B-5%7D%7B4%7D%2B%5Cfrac%7B2%2A4%7D%7B1%2A4%7D%5C%5C%5C%5C%3D%5Cfrac%7B-5%2B8%7D%7B4%7D%3D%5Cfrac%7B3%7D%7B4%7D)

Answer:
149 Millon km is the distance
Answer:
n = ⅜
Step-by-step explanation:
We have that
<span>y = -x</span>²<span>+8x
we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x</span>²+8x--------> x²-8x=0----> x*(x-8)=0
the solution is
x=0
x=8
the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft
the answer is
8 ft
see the attached figure
Solve for the first variable in one of the equations, then substitute the result into the other equation.
3. (1/2, -1,2)
4. (2, -4)
