Tina was observing the changing heights of a ball as it bounced over time. She graphed the function on this coordinate grid to s

how f(x), the height of the dropped ball, in feet, after its xth bounce.
Part A: What does the value of f(3) represent in the given context?

A.
After 4 bounces the height of the ball is 3 feet.

B.
After 3 bounces the height of the ball is 4 feet.

C.
After 4 bounces the height of the ball is 4 feet.

D.
After 3 bounces the height of the ball is 3 feet.


Part B: Tina said that a possible range for the given function is y > 0. Based on the given scenario, do you agree or disagree?

A.
I disagree; because the graph has an asymptote at y = 0, the height cannot be 0.

B.
I disagree; although the graph has an asymptote at y = 0, the ball will stop bouncing and have a height of 0.

C.
I agree; although the graph has an asymptote at y = 0, the ball will stop bouncing and have a height of 0.

D.
I agree; because the graph has an asymptote at y = 0, the height cannot be 0.

The doubling time of a population of grasshoppers is 10 days. By what factor does the population of grasshoppers grow in 35 days
12345 [234]
So in 10 days the grasshopper (x) is doubled (2x)
20 days it is 2(2x) or 4x
30 days it is 2(4x) or 8x
in 35 days it is 1/2 of 10 so 1/2 times 2 times 8x=8x

it increased by a factor of 8

A forester wishes to predict the volume (in cubic feet) of usable lumber in a certain species of tree using the height (in feet)
alex41 [277]

Answer: The response variable = Volume

and explanatory variable(s) in this study are: Height and Diameter.

Step-by-step explanation:

Important definitions:

  • The explanatory variable is a type of independent variable manipulated by the experimenter for the ongoing experimental study.
  • The response variable is a type of dependent variable which depends on the explanatory values provided by the experimenter.

Given: A forester wishes to predict the volume (in cubic feet) of usable lumber in a certain species of tree using the height (in feet) and diameter (in inches) of the trees.

Here, Volume directly depends upon the height and diameter of the tree.

Also, forester ( Experimenter) wants to predict volume by cutting tree that means it is an response variable and it depends on height and diameter , so height and diameter are explanatory variable.

Hence, The response variable = Volume

and explanatory variable(s) in this study are: Height and Diameter.

two dump trucks have capacities of 10 tons and 12 tons. they make a total of 20 round trips to haul 226 tons of topsoil to be us
lozanna [386]
We will define the following variables to solve the problem:
 x = amount of round trips from 10 tons truck
 y = amount of round trips from 12 tons truck
 We write the system of equations:
 x + y = 20
 10x + 12y = 226
 The solution to the system of equations is:
 x = 7
 y = 13
 Answer:
 
10 tons truck makes 7 round trips
 
12 tons truck makes 13 round trips

Ludmilka [50]

203,140

Step-by-step explanation:

f(g(16))=f(16+9)=f(25)=8×25+3=203

g(f(16))=g(8×16+3)=g(131)=131+9=140
