Given the function h(x)=x^2+14x+41, to solve by completing square we procced as follows;
x^2+14x+41=0
x^2+14x=-41
but;
c=(b/2)^2
and b=14
hence;
c=(14/2)^2=49
substituting the value of c in the expression we get:
x^2+14x+49=-41+49
x^2+14x+49=8
(x+7)^2=8
this can be written in vertex form;
h(x)=a(x-h)^2+k
where:
(h,k) is the vertex;
thus
(x+7)^2=8
h(x)=(x+7)^2-8
hence the vertex will be at the point:
(-7,-8)
Answer:
I got $7.75.
Step-by-step explanation:
66.85-4.85=62

Answer: (You have to do a tiny bit of work, but im practically giving you the answer)
Step-by-step explanation: We’re trying to find out how many gallons of gas it takes to drive 1 mile.
1. So, 8 divided by 272= 0.02941176
2. Simplify 0.02941176 and you have your answer!
Answer:
(1, -3) can be removed so that the resulting graph represents a function. A relation from a set X to a set Y is called a function if each element of X is related to exactly one element in Y
Step-by-step explanation:
64 hours per hour average
350 miles ÷5.25 hours in which it took= 63.63 rounded is 64 mph average
