Select the scenarios that correctly represent the given graph

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.

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

you have 6 equal triangles, find the area of one of them (b*h/2) and multiply by 6

(8*4: 2)*6 =

32 cm² is your answer
