tekilochka [14]

You add the time she already drove (15+10) and get 25

56-25 = 31 minutes left.
Now if the 56 minute trip includes the stop at the store, we are OK with that answer. If not, then we have to know how long she stopped at the store and add it onto 31 minutes.

When Determining the Relationship between my height and my weight.

BMI=WEIGHT/HEIGHT*HEIGHT.

BMI is the dependent variable

Weight and height are independent variables.

Step-by-step explanation: Mathematical representation of data or information is a very important strategy applied to solve certain Complex problems.

Mathematical representation helps to make Complex data or information easily understood,it helps one to derive the possible root cause and outcomes of problems,it also shows Relationship between various treatments or variables or drugs applied in solving problems example in treatment of Diseases.

BMI(BODY MASS INDEX) is a life situation where I have used Mathematical representation to solve, it used to show how your height and weight is related.

Independent variables are variables that do not cause any changes t other variables when altered.

Dependent variables are variables which can cause change in a situation when altered.

In this case BMI depends on The weight and height of a person, while the Weight and height of a person are independent on the BMI.

A rocket carrying fireworks is launched from a hill 60 feet above a lake. The rocket will fall into the lake after exploding at

castortr0y [4]

Answer:

Step-by-step explanation:

Given the rocket's height above the surface of the lake given by the function h(t) = -16t^2 + 96t + 60

The velocity of the rocket at its maximum height is zero

v = dh/dt = -32t + 96t

At the maximum height, v = 0

0 = -32t + 96t

32t = 96

t = 96/32

t = 3secs

Substitute t = 3 into the modeled function to get the maximum height

h(3) = -16(3)^2 + 96(3) + 60

h(3) = -16(9)+ 288 + 60

h(3) = -144+ 288 + 60

h(3) = 144 + 60

h(3) = 204

Hence the maximum height reached by the rocket is 204m

Get the height after 2 secs

h(t) = -16t^2 + 96t + 60

when t = 2

h(2) = -16(2)^2 + 96(2) + 60

h(2) = -64+ 192+ 60

h(2) = -4 + 192

h(2) = 188m

Hence the height of the rocket after 2 secs is 188m
