19 1) Natalie shoots an arrow towards the sky
from the top of a 5 meters high building.
As the arrow flies, its height above the
ground can be modeled as the graph
shown. The vertex on the graph
represents which of the following in the
context of the flight of the arrow?
A. the time elapsed and the height at
which the vertical speed of the arrow is at
a maximum
Time second
B. the time elapsed and the height of the
arrow when it reaches its maximum height
C. the time at which the arrow is halfway through its flight.
D. the time at which the vertical speed of the arrow is zero because it has hit the ground

step-by-step explanation:

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
