Step-by-step explanation:
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Solve for x
Subtract x both sides
Adds 1 both sides
The solution is the interval -------> (3,∞)
All real numbers greater than 3
In a number line is the shaded area at right of x=3 (open circle)
see the attached figure
Area is multiplying the width and the length so
area= 3.2 × 1.5 = 4.8
and perimeter is adding all sides together so
perimeter= 3.2 + 3.2 + 1.5 + 1.5 = 9.4
The answer is X.
In order for it to be a function, there should be only one y-value for every x-value. Graph x is the only one that obeys this rule, therefore it is the answer
