Answer:
20 feet
Step-by-step explanation:
Since the term -(x-7)^2 is negative, the largest height that the ball can reach is when this term is 0. 0+20=20, meaning that the highest the ball can go is 20 feet. Hope this helps!
B it is a surd and surds are irrational
An angle is two rays with a common endpoint, called the vertex. The rays are the sides of the angle.
In the angle ∠XYZ, the vertex is Y, and the sides are rays
and
You can name angles by three letters, X on one side, the vertex Y, and Z on the other side: ∠XYZ and ∠ZYX are both names for this angle. Or an angle can be named by just its vertex, for example, ∠Y, as long as it is the only angle with that vertex.
Therefore, the correct option is B
Part A:
f(x) = 20x
Part B:
6 gallons
