The height of a redwood (in meter) tree varies with age (years). Identify the dependent and independent variables.

height is dependent variable

age of redwood is Independent variable.

Step-by-step explanation:

Independent variables are those variables whose value does not gets affected by change in other variable.

dependent variable are those variable are those variables whose value does  gets affected by change in other variable.

means that if there a change in value od one variable then the value of dependent variable also gets changed.

Given

The height of a redwood (in meter) tree varies with age (years).

Here height of redwood will change if age of redwood changes.

hence, height is dependent on age and hence going by definition of dependent variable

height is dependent variable

In the problem age does not change with height of the tree and it is also given that age varies with any other attribute.

hence change in  value of age does not depend on any variable and hence

age of redwood is Independent variable.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13
