The complete question is:

The height of a rocket a given number of seconds after it is released is modeled by h(t) = 6t² + 32t + 10. What does t represent?

Answer:

t represents the number of seconds after the rocket is released.

Step-by-step explanation:

We are told that the height of a rocket a given number of seconds after it is released is modeled by the quadratic equation: h(t) = 6t² + 32t + 10

In this quadratic equation, h (height) is the dependent variable which depends on the number of seconds after rocket is released which is the independent variable

Now, since the independent variable in the function is t, then t definitely represents the number of seconds after rocket is released.

Answer:

|x + 6| = 2

Step-by-step explanation:

|x - b| = c

b is the centre: (-4-8)/2 = -6

b = -6

c is the distance from the centre

-6 - (-8) = -6 + 8 = 2

Or,

-4 - (-6) = -4 + 6 = 2

| x - (-6)| = 2

|x + 6| = 2

A chemical balance needs to weigh 237g using weights of 50g, 20g, 10g and 1g. How many of each weight is needed?

Delicious77 [7]

The required number of weights used in chemical balance to weigh 237g is 4,1,1,7 respectively.

What is mathematical expression?

A mathematical expression expression in mathematical is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Here, it is given that :

A chemical balance needs to weigh 237g using weights of 50g, 20g, 10g and 1g.

Now, let us find the number of weights for each weight type :

For 50g weight the maximum number of weights needed will be 4 that is :

50g x 4 = 200g

Now, for 20g weight the maximum number of weights needed will be 1 that is :

20g x 1 = 20g

Now, for 10g weight the maximum number of weights needed will be 1 that is :

10g x 1 = 10g

Now, for 1g weight the maximum number of weights needed will be 7 that is :

1g x 7 = 7g

Adding all the weights we get :

200g + 20g + 10g + 7g = 237g;

which is the required weight and the number of weights used is 4,1,1,7 respectively.
