Answer:
d=rt
r=420 per hr, 3 hrs = 420/3= 140
t=1
d=140×1=140miles
Comparing to the standard equation, the parabola with a vertex at (-2,0) is given by:
y = (x + 2)²
<h3>What is the equation of a parabola given it’s vertex?</h3>
The equation of a quadratic function, of vertex (h,k), is given by:
y = a(x - h)² + k
In which a is the leading coefficient.
In this problem, we have that h = -2 and k = 0, and all the options have leading coefficient a = 1, hence the equation is:
y = (x + 2)²

Answer:
The watermelon weighs more.
Step-by-step explanation:
I know this because 1 kilogram is equal to 2.20462 pounds. This means that 7.5 kilograms weighs as much as 16.5347 pounds. 16.5347 is greater than 12, so this means the watermelon weighs more.
