The expression 16t2 represents the distance in feet an object falls after t seconds. The object is dropped from a height of 906 feet.
Write an expression representing the height of the object in feet t seconds
after it is dropped.
0906 - 16t^2
906 + 16t^2
0906 (16t^2)
0906/16t^2

824 feet

that is becuase the greastist common factor adds up to that

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
