Jenna calculated several numbers in her calculator. the result displayed 1.8e-4 on the calculator screen. which equivalent number(s) does this represent? select all that apply. 18 × 104 -0.00018 0.00018 1800 1.8 × 10-4 will mark best answer!

0.00018 and 1.8 × 10-4

Step-by-step explanation:

Jenna calculated several numbers in her calculator. The result displayed 1.8E-4 on the calculator screen.

1.8E^-4 means there are 3 zeroes after decimal then 18. When a value is very less than zero then the calculator shows that in E form. When we move the decimal to the left, it adds 1 to our exponent.

So, the correct answers are :

0.00018 and 1.8 × 10-4

1.8 × 10-4 =

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

x = 23.78
