When multiplying the same base with exponents, you keep the base the same and then you add the exponents, so for this question you do:
10^3 x 10^6
10^9

Answer:
Vertex is (2,0)
Step-by-step explanation:
The vertex of a parabola is x=-b/2a
Since a=-2 and b=8, we have:
x=-8/2(-2)
x=-8/-4
x=2
So the vertex is (2,0)
Answer:
The answer is option A.
p = 0.7(rh + b)
Making h the subject
divide both sides by 0.7
we get
p/0.7 = rh + b
send b to the left side of the equation
p / 0.7 - b = rh
divide both sides by r
we get
( p / 0.7 - b) ÷ r = h
therefore h = ( p / 0.7 - b ) ÷ r
Hope this helps
