A) Every T is worth 7 points, and every F is worth 3 points.  So if we let T = 7 and F = 3, we can count how many T's and F's each team scored and write it as an expression.


So for the East Side Bulldogs, they have 7 touchdowns and 6 field goals, thus the expression for them is:

7T + 6F

For the West Side Bulldogs, they have 5 touchdowns and 5 field goals, thus the expression for them is:

5T + 5F

B) The difference would be written as:
7T + 6F - (5T + 5F) = 2T + F

C) To determine how many more points the winning team has than the losing team, calculate the scores of the two teams.  Then subtract the smaller number from the larger number to determine the score differential.

A 45 kg skydiver has a speed of 25 m/s at an altitude of 950 meters above the ground. Determine the
Montano1993 [528]

The kinetic energy possessed by the skydiver is 14, 062. 5 Joules

<h3>What is kinetic energy?</h3>

Kinetic energy of an object is defined as the energy possessed by an object due to its motion.

It is also described as the work that is required to accelerate a body of mass from rest to its given velocity.

The formula for calculating kinetic energy is expressed as;

Kinetic energy = 1/2 mv²

Where;

  • m is the mass of the object
  • v is the velocity of the object

Now, substitute the values

Kinetic energy = 1/2 (45)(25)²

Find the square

Kinetic energy = 1/2 (45)(625)

Find the product

Kinetic energy = 1/2(28125)

Find the quotient

Kinetic energy = 14, 062. 5 Joules

Hence, the value is  14, 062. 5 Joules
