You plant a tree that is 36 inches tall. After one year, the tree is 43 inches tall. Which expression describes the percent of i
Inessa05 [86]




36 - 100%43 - x  %
we multiply by cross ->  36 * x = 100 / 43 
we should remove '100%' from new value, because we find only increase.. no new value in percent.
x + 100 = (43 * 100)/36 
x =  4300/36 - 100x = 119+ 16/36 -100x = 19 +4/9



the answer is 

19.44% increase

Mark stated that the slope of the line that passes through these two points (1, -19) and (-2, -7) is -¼. Is Mark correct? Explai
ladessa [460]

9514 1404 393

Answer:

  no

Step-by-step explanation:

The slope formula is ...

  m = (y2 -y1)/(x2 -x1)

We can use the values ...

  (x1, y1) = (1, -19)

  (x2, y2) = (-2, -7)

Putting these into the formula gives ...

  m = (-7 -(-19))/(-2 -1) = 12/-3 = -4

The slope is -4, not -1/4. Mark is incorrect.

Write an equation that is perpendicular to y=3/5x-1 and passes through the point (9,14)
Leokris [45]

Answer:

y=(-5/3)x+29

Step-by-step explanation:

we will use the base formula y=mx+b

In order to be perpendicular, the slope must be the flipped fraction and have the opposite sign, so our m is (-5/3)

y=(-5/3)x+b

You can plug in the (9,14) point in order to find the b

14=(-5/3)(9)+b

14=(-45/3)+b

14=(-15)+b

14+15=b

29=b

and so altogether our equation is y=(-5/3)x+29

Draw a line graph that represents the relationship between mass and kinetic energy in Experiment 2. Make sure to give the graph
Leya [2.2K]

The linear function that maps the relation between kinetic energy and mass is given at the end of the question.

<h3>What is the kinetic energy of an object?</h3>

The kinetic energy of an object is given by the following formula:

E = 0.5mv².

In which:

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

In this problem, we suppose a velocity of 2.5 m/s, hence the kinetic energy is:

E = 0.5m(2.5)² = 3.125m.

Hence the graph is plotted at the end of the answer.
