Answer:

x = ~8.9

Step-by-step explanation:

a^2 + b^2 = c^2

c is the long side

a and b are the other two shorter sides

this means

x^2 + 19^2 = 21^2

x^2 + 361 = 441

x^2 = 441- 361

x^2 = 441- 361

x^2 = 80

square root of 80 = ~8.9

x = ~8.9

Select the scenarios that correctly represent the given graph
sammy [17]

Answer:

Option 1 and option 5.

Step-by-step explanation:

The given graph is a downward parabola. It means the value of function increases and after reaching its maximum point the value of function decreases.

Scenario 1 : The height of a stone shot by a catapult reaches a maximum height and then falls on the ground.

The graph of this scenario is a downward parabola. Therefore option 1 is correct.

Scenario 2 : The speed of a car increases constantly by 10 miles per hour.

The graph of this scenario is a straight line with slope 10. Therefore option 2 is incorrect.

Scenario 3 : The radioactivity of a substance decreases by 10% every year.

The graph of this scenario is an decreasing curve which represents an exponential function. Therefore option 3 is incorrect.

Scenario 4 : The amount of money in an account decreases for a few months and then increases.

The graph of this scenario is a upward parabola. Therefore option 4 is incorrect.

Scenario 5 : The sale of product increases at first and then decreases.

The graph of this scenario is a downward parabola. Therefore option 5 is correct.

Therefore, the correct options are 1 and 5.
