What is the mapping notation that will transform triangle ABC to triangle A'B'C'?
A.(x + 2,y - 14)
B.(x - 4, y - 8)
C.(y, -x)
D.(-y, x)

Answers

Answer:

The transformation is (y,-x)

Step-by-step explanation:

To know the mapping notation, we need to know the coordinates of the image and the pre-image

For the pre-image, we have;

A(3,8)

B(6,8)

C(6,2)

For the image, we have

A’( 8,-3)

B’ (8,-6)

C’ (2,-6)

So let us try and get the transformation from the coordinates

We can see that this is;

(x,y) to (y,-x)

Amanda increased the amount of protein she eats every day from 48g to 54g. By what percentage did Amanda increase the amount of protein she eats?

Answers

Answer:

Explanation:

The formula for calculating the percent change is:

p=N−OO⋅100

Where:

p is the percent change - what we are looking for

N is the New Value - 54g for this problem

O is the Old Value - 48g for this problem

Substituting and calculating p gives:

p=54−4848⋅100

p=648⋅100

p=60048

p=12.5

Please MARK AS BRAINLIEST

Answer:

12.5%! :)

Step-by-step explanation:

The formula for calculating the percent change is:

p=N−OO⋅100

Where:

p is the percent change - what we are looking for

N is the New Value - 54g for this problem

O is the Old Value - 48g for this problem

Substituting and calculating p gives:

p=54−4848⋅100

p=648⋅100

p=60048

p=12.5

which means that our answer would be 12.5%

In 2000 jonesville had a population of 15,000. In 2001 the population was 16,250 and in 2002 the population was 17,500 in the population grew at the same constant rate each year which model describes the population growth for n years after 2000?

Answers

Answer:

15000+1250x

Step-by-step explanation:

Since the initial population is 15,000, we want to know how many people are going to Jonesville each year.  Assuming that in 2001 and in 2002, each year adds 1,250 people and that it is constant.  The equation is 15000+1250x in which 15,000 represents the initial number and 1250 is the amount of people added each year followed by x which is the number in years.

A man ran on a treadmill for 1,600 seconds. At the end of his run, the treadmill indicated his energy output as 240,000 J. What average power did he generate?

Answers

Answer:150 watts

Step-by-step explanation: Alright so first we need to know our equation and what we're given. So for the equation its P=w/t where work also equals change in energy. So if time is 1,600 seconds and work or energy is 240,000 J then Power equals 240,000J/1,600 sec = 150 Watts

Laura and Kennedy are at softball practice. Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second. Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second.

Answers

Answer:

C

Step-by-step explanation:

The system of equations [tex]y = -16x^2+60x+3\\y=-16x^+55x+2.5[/tex]  models the projectile motion of the two balls. option C is correct.

Laura and Kennedy are at softball practice. Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second. Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second. The projectile equations is to be determined.

What is the projectile motion?

Projectile motion is the movement of an entity projected into the space. After the initial force that launches the object, it only experiences the force of gravity. The object is called a projectile, and its path is called its trajectory.

Projectile equation = vertical motion + horizontal motion + intercept.

Laura hits a ball that is 3 feet above the ground with an initial upward velocity of 60 feet per second.
y = gx²/2 + v*x + 3
y = -32/2 * x² + 60x + 3
y = -16x² + 60x + 3

Similarly, Kennedy hits a ball that is 2.5 feet above the ground with an initial upward velocity of 55 feet per second.
y = -16x² + 55x + 2.5

Thus, the system of equations [tex]y = -16x^2+60x+3\\y=-16x^+55x+2.5[/tex]  models the projectile motion of the two balls. option C is correct.

Answer: x equals forty one over five

Step-by-step explanation: Add the numbers 18x-15+3x-11+4x+1=180 18x-25+3x+4x=180 then you combine like terms and you get, 18x-25+3x+4x=180 25x-25=180 then you add 5 to both sides of the equation 25x-25=180. 25x-25+25=180+25 then you simplify then you add the numbers 25x=205 then you divide both sides of the equation by the same term 25x=205 25x/25 = 205/25 then you simplify, you cancel terms that are in both the numerator and denominator then you divide the numbers and you get, x equals forty one over five.
