To get the points at which the two boats meet we need to find the equations that model their movement:
Boat A:
vertex form of the equation is given by:
f(x)=a(x-h)^2+k
where:
(h,k) is the vertex, thus plugging our values we shall have:
f(x)=a(x-0)^2+5
f(x)=ax^2+5
when x=-10, y=0 thus
0=100a+5
a=-1/20
thus the equation is:
f(x)=-1/20x^2+5
Boat B
slope=(4-0)/(10+10)=4/20=1/5
thus the equation is:
1/5(x-10)=y-4
y=1/5x+2
thus the points where they met will be at:
1/5x+2=-1/20x^2+5
solving for x we get:
x=-10 or x=6
when x=-10, y=0
when x=6, y=3.2
Answer is (6,3.2)
Answer: 1/10
Step-by-step explanation: because there are 10 numbers (1,2,3,4,5,6,7,8,9, and 0)
Answer:
(A)
Step-by-step explanation:
Given the equations:
Substitution simply means replacing the variable y in the second equation with its equivalent x+3 from the first equation.
Substitution of y into 
gives us:
The correct option is A.
